Mac版Xamarin Android Player无法启动，提示内核驱动未加载该如何解决？

Hey there, let's tackle this kernel driver issue head-on—this is a common snag with XAP on High Sierra, and I've got a few tried-and-true solutions that should get you up and running:

1. Manually Load the Kernel Driver via Terminal #

First, let's try forcing the driver to load directly. Open up your Terminal app and run these commands one by one:

• Unload any partially loaded instance first:

  sudo kextunload /Library/Extensions/xamarin.android.player.kext
  

• Then load the driver with elevated permissions:

  sudo kextload /Library/Extensions/xamarin.android.player.kext
  

You'll need to enter your Mac's admin password when prompted. After this, close Terminal and try launching Xamarin Android Player again.

2. Allow Third-Party Kernel Extensions in Security Settings #

macOS 10.13+ has stricter security rules for kernel extensions, so you might need to manually approve Xamarin's driver:

• Open System Preferences → Security & Privacy → General tab.
• Look for a message at the bottom that says "System software from developer 'Xamarin Inc.' was blocked from loading".
• Click the Allow button next to this message.
• Once approved, go back to Terminal and re-run the sudo kextload command from step 1, then restart XAP.

3. Fix Permissions for the Kernel Driver #

Sometimes incorrect file permissions can prevent the driver from loading. Let's reset them:

• Run this command in Terminal to set the correct ownership:

  sudo chown -R root:wheel /Library/Extensions/xamarin.android.player.kext
  

• Then reload the driver again with:

  sudo kextload /Library/Extensions/xamarin.android.player.kext
  

4. Full Uninstall and Reinstall Xamarin Android Player #

If the above steps don't work, a clean reinstall might do the trick:

• Drag Xamarin Android Player from your Applications folder to the Trash.
• Delete these leftover files/folders (use Finder's "Go to Folder" with Cmd+Shift+G):
  • ~/Library/Application Support/XamarinAndroidPlayer
  • /Library/Extensions/xamarin.android.player.kext
• Download the 0.6.5 installer again, run it, and go through the setup.
• After installation, don't launch XAP yet—head to Security & Privacy to approve the kernel extension first, then start the app.

A quick note: If you don't see the "Allow" button in Security & Privacy right away, restart your Mac first, then check the settings immediately after logging back in.
