Can you use Microsoft Remote Desktop to connect to your MacBook or iMac? The answer is a bit more nuanced than a simple yes or no. While Microsoft's remote desktop solution (now updated and rebranded as the Windows App) doesn't support remote controlling a Mac from another device, it does allow you to control a Windows PC from your Mac, and that's what most of you are trying to do.

Whether you're working from home, supporting a remote client, or simply trying to log into your office PC from a MacBook, Microsoft's remote desktop tool remains one of the most stable and secure options. In this guide, we'll walk you through exactly how to use Microsoft Remote Desktop on a Mac, help you determine if it's the right fit for your remote access needs, and introduce a great alternative, DeskIn, if you're looking for more flexibility or features. You can use DeskIn to remotely control a Mac in less than 3 minutes.

👀 Note: If you're interested in the transition from Microsoft Remote Desktop to the Windows app, read the following articles for more information.

How to Download and Set Up Microsoft Remote Desktop on Mac

Microsoft has gradually replaced the Microsoft Remote Desktop connection for Mac with the new Windows App, which supports services like Windows 365, Azure Virtual Desktop, and RemoteApp. If you're still using the older version, it's recommended to upgrade for continued support and improved features to control your Windows PC from your Mac with ease..

Currently, you can only download the Windows App through the Mac App Store. Unfortunately, there is no offline installer, nor can you download the app directly via a browser. Here's how to easily download and set up Microsoft's Windows App for macOS from the App Store:

Step 1. Download Microsoft Remote Desktop from the Mac App Store

  • Open the Mac App Store.

  • In the search bar, type "Microsoft Remote Desktop" or "Windows App".

  • Click on the correct listing and download the latest version of the app.

Once the app is downloaded and installed, open it from your Applications folder to begin the setup process.

Log in to Windows App on Mac

Step 2. Enable Remote Desktop on Your Windows PC

  • On your Windows PC, go to "System Settings > Remote Desktop".

  • Toggle on the option to allow remote connections.

  • Ensure that the PC remains powered on and connected to the internet.

Your Windows PC must stay accessible for remote sessions, so confirm that it's not set to automatically sleep or turn off.

Step 3. Add Your PC to Microsoft Remote Desktop on Mac

  • On your Mac, open the Windows App (Microsoft Remote Desktop).

  • Click on the "+ Add PC" button.

  • Enter the PC name (device name) or IP address of the Windows PC you want to connect to. You can find this information on the Windows PC by going to "Settings > System > About" or by running "ipconfig" in the "Command Prompt".

  • Enter the "Windows account credentials" (username and password) used on the target PC.

Step 4. Customize Your Connection Preferences

Before connecting, you can configure various settings to improve the experience:

  • Display settings: Adjust the resolution to match your screen size.

  • Audio redirection: Decide if you want to hear sound from your Windows PC through your Mac.

  • Clipboard sharing: Enable copy/paste between your Mac and the Windows PC.

  • Local resources: Share local folders and printers, if necessary.

Make sure to tailor these preferences based on your connection speed and specific use case (work tasks, gaming, remote support, etc.). Optimizing these settings can make a significant difference in the quality of your remote session.

Step 5. Connect to Your Windows PC

Once you've configured all your preferences, click the "Connect" button. After a brief loading period, the full Windows desktop environment will appear on your Mac, giving you full control as though you were sitting right in front of the PC. Now, you can use your Windows PC remotely from your Mac seamlessly!

Tips for a Smooth Microsoft Remote Desktop User Experience

When using Microsoft Remote Desktop to control your Mac from Windows or vice versa, optimizing both the setup and connection quality can significantly enhance your remote access experience. Here are some tips to ensure a smooth and uninterrupted session.

  • Keep Your Windows PC Always On or Enable Wake-on-LAN. Ensure your Windows PC stays powered on or enables Wake-on-LAN. This feature allows your PC to be remotely awakened from sleep or hibernation. Without this, you won't be able to establish a connection if the PC is turned off.

  • Optimize Your Network Connection For the best experience.

  • Wired Ethernet: Provides the most stable and fastest connection, reducing latency.

  • 5GHz Wi-Fi: Offers faster speeds and less interference compared to 2.4GHz, improving overall performance.

  • Use the Same Network (If Possible) For better speed and responsiveness, ensure both your Windows PC and Mac are connected to the same local network (Wi-Fi or Ethernet).

  • Use Multiple Monitors. If you have multiple displays, Microsoft Remote Desktop can extend your desktop. This feature is useful for multitasking, so configure your display settings accordingly.

💥 Microsoft Remote Desktop – Key Drawbacks:

  • Windows Pro required: Not supported on Windows Home editions.

  • Complex setup for remote access: Needs port forwarding or VPN for external connections.

  • Single user session only: Doesn’t support multiple simultaneous users.

  • Performance issues on weak networks: laggy under low bandwidth or high latency.

  • Limited mobile experience: Mobile apps are basic and not touch-optimized.

FAQs About Microsoft Remote Desktop Connection for Mac

Does Microsoft Remote Desktop for Mac support dual monitors?

Yes. The Windows App (formerly Microsoft Remote Desktop) for Mac supports multiple monitors when connecting to a Windows PC. You can enable this feature by going to your PC's display settings in the app and selecting the option to "Use all monitors." This is especially useful for multitasking or extended workspace setups.

Can I transfer files from my Mac to the Windows PC during a session?

Yes, but with limitations. While Microsoft Remote Desktop does not support direct drag-and-drop file transfers between Mac and Windows, you can share local Mac folders with the remote Windows session. Simply configure folder redirection in the PC's connection settings under the "Folders" tab before connecting.

If that's too limited or slow, DeskIn enables high-speed file transfer with full drag-and-drop — no folder mapping or advanced configuration needed.

Does Microsoft Remote Desktop work over the internet or only on local networks?

It works both ways. You can access your Windows PC from your Mac over the internet as long as the PC is configured correctly, has a public IP address or VPN access, and Remote Desktop is enabled. For best performance, ensure both devices have stable internet connections.

Can Microsoft Remote Desktop connect to a Mac from a Windows PC?

No. Currently, Microsoft Remote Desktop does not support remote control of a Mac from a Windows PC. It only allows controlling a Windows PC from a Mac. If you need to remote control a Mac from Windows, you'll need to use a third-party solution like DeskIn.

Final Words

Connecting your Mac to Microsoft Remote Desktop is a reliable way to access your Windows PC remotely, ideal for personal use or working across platforms. With just a few setup steps, downloading the Windows App from the Mac App Store, enabling Remote Desktop on your Windows PC, and configuring your connection, you can enjoy full control of your Windows desktop from macOS.

For simple, everyday use, Microsoft Remote Desktop offers a solid and secure solution.

Why Is My TeamViewer Not Connecting?

If TeamViewer can’t connect, shows “Unable to connect to partner,” or gets stuck on “Connecting,” or even fails to log in, the issue usually comes from one of several core areas. Common causes include unstable internet, incorrect Windows permissions, firewall or proxy blocking, IPv6 conflicts, licensing errors, or temporary server maintenance.

9 Ways to Fix TeamViewer Connection Issues

Whether you’re using the free or business edition of TeamViewer on Windows, macOS, iPhone/iPad, or Android, these 9 fixes will help you troubleshoot and restore your connection quickly. These steps are simple, effective, and compatible with all devices to ensure smooth remote access.

For more device-based tutorials, check out:

Method 1: Check Internet Connection and VPN Status

Network instability is the most common reason for TeamViewer connection failures. Unstable Wi-Fi, VPN misconfigurations, or proxies may cause timeouts or connection blocking.

Steps:

  1. Press Win + R, type cmd, and hit Enter.

  2. Type ping -t 8.8.8.8 and observe the response time. If latency spikes or packets drop frequently, your network is unstable.

  3. Use Speedtest to check your internet speed or restart your router / switch to a wired connection for better stability.

check network speedtest

If your internet is fine but TeamViewer still won’t connect, move on to the next fix.

Method 2: Change TeamViewer Access Permissions

If you can’t connect or can’t control your partner’s screen, your access permissions may be too limited.

Steps:

  1. On the remote computer, open TeamViewer, click the gear icon, and open Options.

  2. Go to Advanced, then click Show advanced options.

  3. Under “Advanced settings for connections to this computer,” set Access Control to Full Access.

This ensures you have full control and can solve most permission-related connection problems.

Method 3: Check and Adjust Windows Settings

If TeamViewer keeps failing to connect, Windows User Account Control (UAC) or Remote Desktop settings may be interfering.

  • Make sure UAC allows TeamViewer to make system changes.

  • Verify that Remote Desktop services are running.

  • Restart your computer after major Windows or TeamViewer updates.

Method 4: Adjust Firewall and Proxy Settings

Windows Firewall or proxy restrictions can block TeamViewer’s necessary ports.

Steps:

  1. Open Windows Defender Firewall → Allow an app through Firewall.

  2. Click Change settings, then ensure TeamViewer Remote Control Service is checked.

  3. Go to Control Panel → Internet Options → Connections → LAN Settings, and uncheck Use a proxy server for your LAN if it’s enabled.

If it’s too complex to reconfigure, consider switching to DeskIn — it connects instantly without firewall hassle.

Method 5: Disable IPv6 on Both Computers

IPv6 incompatibility can sometimes cause connection failures.

Steps:

  1. Press Win + R, type ncpa.cpl, and hit Enter.

  2. Right-click your active network → Properties.

  3. Uncheck Internet Protocol Version 6 (TCP/IPv6) and click OK.

  4. Repeat the same on the remote PC.

Reboot and retry — this often resolves unknown “Cannot connect to partner” errors.

Method 6: Update or Reinstall TeamViewer

Outdated or unofficial versions can lead to compatibility issues.

Steps:

  1. Open TeamViewer → Menu (≡) → Check for new version.

  2. If updating doesn’t help, uninstall TeamViewer from Control Panel → Programs and Features, then reinstall the latest version from the official website.

Pro tip: If you’re on Mac, you can also use Microsoft Remote Desktop or turn your iPad into a second screen for smoother multitasking.

Method 7: Refresh DNS and TCP/IP via CMD

If login or verification fails, network cache may be corrupted.

Steps:

  1. Open CMD as Administrator.

  2. Type the following commands one by one:

ipconfig /release  

ipconfig /flushdns  

ipconfig /renew  

nbtstat –r  

netsh int ip reset resetlog.txt  

netsh winsock reset

teamviewer cmd refresh
  1. Restart your PC and reconnect TeamViewer.

Method 8: Check TeamViewer Server Status

Sometimes, the issue isn’t on your end.

Steps:

  1. Visit the TeamViewer server status page.

  2. Check if your regional servers are down.

  3. If there’s downtime, wait or use DeskIn as a stable alternative.

Method 9: Perform a Clean Boot to Eliminate Background Conflicts

Antivirus or startup apps may interfere with TeamViewer.

Steps:

  1. Press Win + R, type msconfig, and hit Enter.

  2. Under General, select Selective startup and uncheck “Load startup items.”

  3. In Services, check “Hide all Microsoft services” and click Disable all.

  4. Restart your PC.

  5. Temporarily disable antivirus software and try connecting again.

This isolates background conflicts that cause TeamViewer connection drops.

Fixing “Commercial Use Detected” on TeamViewer

Even personal users are sometimes flagged for commercial use due to TeamViewer’s detection algorithms. This disrupts workflow and limits functionality. You can appeal to unlock your account or switch to DeskIn, which allows free commercial usage without restrictions.

Why Does TeamViewer Flag for Commercial Use?

TeamViewer monitors your IP, domain, connection frequency, and activity. Using corporate domains or connecting to multiple devices may trigger a “commercial use suspected” warning.

How to Submit an Appeal

  1. Visit the TeamViewer Commercial Use Suspected page.

    teamviewer commerical use form
  2. Fill out your name, email, affected TeamViewer ID, and explain your personal use case.

  3. Upload your log files

  4. Wait about 7 days for review.

After approval, your account will return to the free version.

Temporary Workaround: Use DeskIn

If you’re locked out of TeamViewer, DeskIn offers free, unrestricted remote control for both personal and business use. It’s fast, stable, and won’t get blocked for “commercial activity.”

  1. Press Win + R, type cmd, and hit Enter.

  2. Type ping -t 8.8.8.8 and observe the response time. If latency spikes or packets drop frequently, your network is unstable.

  3. Use Speedtest to check your internet speed or restart your router / switch to a wired connection for better stability.

check network speedtest

If your internet is fine but TeamViewer still won’t connect, move on to the next fix.

Method 2: Change TeamViewer Access Permissions

If you can’t connect or can’t control your partner’s screen, your access permissions may be too limited.

Steps:

  1. On the remote computer, open TeamViewer, click the gear icon, and open Options.

  2. Go to Advanced, then click Show advanced options.

  3. Under “Advanced settings for connections to this computer,” set Access Control to Full Access.

This ensures you have full control and can solve most permission-related connection problems.

Method 3: Check and Adjust Windows Settings

If TeamViewer keeps failing to connect, Windows User Account Control (UAC) or Remote Desktop settings may be interfering.

  • Make sure UAC allows TeamViewer to make system changes.

  • Verify that Remote Desktop services are running.

  • Restart your computer after major Windows or TeamViewer updates.

Method 4: Adjust Firewall and Proxy Settings

Windows Firewall or proxy restrictions can block TeamViewer’s necessary ports.

Steps:

  1. Open Windows Defender Firewall → Allow an app through Firewall.

  2. Click Change settings, then ensure TeamViewer Remote Control Service is checked.

  3. Go to Control Panel → Internet Options → Connections → LAN Settings, and uncheck Use a proxy server for your LAN if it’s enabled.

If it’s too complex to reconfigure, consider switching to DeskIn — it connects instantly without firewall hassle.

Method 5: Disable IPv6 on Both Computers

IPv6 incompatibility can sometimes cause connection failures.

Steps:

  1. Press Win + R, type ncpa.cpl, and hit Enter.

  2. Right-click your active network → Properties.

  3. Uncheck Internet Protocol Version 6 (TCP/IPv6) and click OK.

  4. Repeat the same on the remote PC.

Reboot and retry — this often resolves unknown “Cannot connect to partner” errors.

Method 6: Update or Reinstall TeamViewer

Outdated or unofficial versions can lead to compatibility issues.

Steps:

  1. Open TeamViewer → Menu (≡) → Check for new version.

  2. If updating doesn’t help, uninstall TeamViewer from Control Panel → Programs and Features, then reinstall the latest version from the official website.

Pro tip: If you’re on Mac, you can also use Microsoft Remote Desktop or turn your iPad into a second screen for smoother multitasking.

Method 7: Refresh DNS and TCP/IP via CMD

If login or verification fails, network cache may be corrupted.

Steps:

  1. Open CMD as Administrator.

  2. Type the following commands one by one:

ipconfig /release  

ipconfig /flushdns  

ipconfig /renew  

nbtstat –r  

netsh int ip reset resetlog.txt  

netsh winsock reset

teamviewer cmd refresh
  1. Restart your PC and reconnect TeamViewer.

Method 8: Check TeamViewer Server Status

Sometimes, the issue isn’t on your end.

Steps:

  1. Visit the TeamViewer server status page.

  2. Check if your regional servers are down.

  3. If there’s downtime, wait or use DeskIn as a stable alternative.

Method 9: Perform a Clean Boot to Eliminate Background Conflicts

Antivirus or startup apps may interfere with TeamViewer.

Steps:

  1. Press Win + R, type msconfig, and hit Enter.

  2. Under General, select Selective startup and uncheck “Load startup items.”

  3. In Services, check “Hide all Microsoft services” and click Disable all.

  4. Restart your PC.

  5. Temporarily disable antivirus software and try connecting again.

This isolates background conflicts that cause TeamViewer connection drops.

Fixing “Commercial Use Detected” on TeamViewer

Even personal users are sometimes flagged for commercial use due to TeamViewer’s detection algorithms. This disrupts workflow and limits functionality. You can appeal to unlock your account or switch to DeskIn, which allows free commercial usage without restrictions.

Why Does TeamViewer Flag for Commercial Use?

TeamViewer monitors your IP, domain, connection frequency, and activity. Using corporate domains or connecting to multiple devices may trigger a “commercial use suspected” warning.

How to Submit an Appeal

  1. Visit the TeamViewer Commercial Use Suspected page.

    teamviewer commerical use form
  2. Fill out your name, email, affected TeamViewer ID, and explain your personal use case.

  3. Upload your log files

  4. Wait about 7 days for review.

After approval, your account will return to the free version.

Temporary Workaround: Use DeskIn

If you’re locked out of TeamViewer, DeskIn offers free, unrestricted remote control for both personal and business use. It’s fast, stable, and won’t get blocked for “commercial activity.”

Besides DeskIn, there are several traditional ways to transfer photos from iPhone to Windows. Below are four reliable methods — both wired and wireless — including their limitations and setup requirements.

1. Transfer via USB Cable (Windows 10/11)

  2. Unlock your iPhone and tap Trust This Computer when prompted.

  3. On your PC, open File Explorer → find your iPhone under “This PC.”

  4. Open Internal Storage > DCIM, where your camera photos and videos are stored.

  5. Copy and paste (Ctrl+C / Ctrl+V) the desired photos or folders into a target location on your PC.

Tip: If your PC can’t read HEIC files, go to Settings > Camera > Formats on iPhone and select Most Compatible, or install a HEIC extension on your PC.

Read more:

2. Use iCloud for Windows

The biggest advantage of iCloud is wireless synchronization—no cables required.
However, it depends on internet speed and only offers 5GB of free storage.

Steps:

  1. Download iCloud for Windows from the Microsoft Store.

  2. Sign in with your Apple ID (same as your iPhone).

9 Ways to Fix TeamViewer Connection Issues

Whether you’re using the free or business edition of TeamViewer on Windows, macOS, iPhone/iPad, or Android, these 9 fixes will help you troubleshoot and restore your connection quickly. These steps are simple, effective, and compatible with all devices to ensure smooth remote access.

For more device-based tutorials, check out:

Method 1: Check Internet Connection and VPN Status

Network instability is the most common reason for TeamViewer connection failures. Unstable Wi-Fi, VPN misconfigurations, or proxies may cause timeouts or connection blocking.

Steps:

  1. Press Win + R, type cmd, and hit Enter.

  2. Type ping -t 8.8.8.8 and observe the response time. If latency spikes or packets drop frequently, your network is unstable.

  3. Use Speedtest to check your internet speed or restart your router / switch to a wired connection for better stability.

check network speedtest

If your internet is fine but TeamViewer still won’t connect, move on to the next fix.

Method 2: Change TeamViewer Access Permissions

If you can’t connect or can’t control your partner’s screen, your access permissions may be too limited.

Steps:

  1. On the remote computer, open TeamViewer, click the gear icon, and open Options.

  2. Go to Advanced, then click Show advanced options.

  3. Under “Advanced settings for connections to this computer,” set Access Control to Full Access.

This ensures you have full control and can solve most permission-related connection problems.

Method 3: Check and Adjust Windows Settings

If TeamViewer keeps failing to connect, Windows User Account Control (UAC) or Remote Desktop settings may be interfering.

  • Make sure UAC allows TeamViewer to make system changes.

  • Verify that Remote Desktop services are running.

  • Restart your computer after major Windows or TeamViewer updates.

Method 4: Adjust Firewall and Proxy Settings

Windows Firewall or proxy restrictions can block TeamViewer’s necessary ports.

Steps:

  1. Open Windows Defender Firewall → Allow an app through Firewall.

  2. Click Change settings, then ensure TeamViewer Remote Control Service is checked.

  3. Go to Control Panel → Internet Options → Connections → LAN Settings, and uncheck Use a proxy server for your LAN if it’s enabled.

If it’s too complex to reconfigure, consider switching to DeskIn — it connects instantly without firewall hassle.

Method 5: Disable IPv6 on Both Computers

IPv6 incompatibility can sometimes cause connection failures.

Steps:

  1. Press Win + R, type ncpa.cpl, and hit Enter.

  2. Right-click your active network → Properties.

  3. Uncheck Internet Protocol Version 6 (TCP/IPv6) and click OK.

  4. Repeat the same on the remote PC.

Reboot and retry — this often resolves unknown “Cannot connect to partner” errors.

Method 6: Update or Reinstall TeamViewer

Outdated or unofficial versions can lead to compatibility issues.

Steps:

  1. Open TeamViewer → Menu (≡) → Check for new version.

  2. If updating doesn’t help, uninstall TeamViewer from Control Panel → Programs and Features, then reinstall the latest version from the official website.

Pro tip: If you’re on Mac, you can also use Microsoft Remote Desktop or turn your iPad into a second screen for smoother multitasking.

Method 7: Refresh DNS and TCP/IP via CMD

If login or verification fails, network cache may be corrupted.

Steps:

  1. Open CMD as Administrator.

  2. Type the following commands one by one:

ipconfig /release  

ipconfig /flushdns  

ipconfig /renew  

nbtstat –r  

netsh int ip reset resetlog.txt  

netsh winsock reset

teamviewer cmd refresh
  1. Restart your PC and reconnect TeamViewer.

Method 8: Check TeamViewer Server Status

Sometimes, the issue isn’t on your end.

Steps:

  1. Visit the TeamViewer server status page.

  2. Check if your regional servers are down.

  3. If there’s downtime, wait or use DeskIn as a stable alternative.

Method 9: Perform a Clean Boot to Eliminate Background Conflicts

Antivirus or startup apps may interfere with TeamViewer.

Steps:

  1. Press Win + R, type msconfig, and hit Enter.

  2. Under General, select Selective startup and uncheck “Load startup items.”

  3. In Services, check “Hide all Microsoft services” and click Disable all.

  4. Restart your PC.

  5. Temporarily disable antivirus software and try connecting again.

This isolates background conflicts that cause TeamViewer connection drops.

Fixing “Commercial Use Detected” on TeamViewer

Even personal users are sometimes flagged for commercial use due to TeamViewer’s detection algorithms. This disrupts workflow and limits functionality. You can appeal to unlock your account or switch to DeskIn, which allows free commercial usage without restrictions.

Why Does TeamViewer Flag for Commercial Use?
