[MacOS] ATLab ‘Play’ button not working

[Sandra T]

Hello! I’m on the VM setup guide and I just finished the ‘Customize Settings’ step. The next step is to click the play button in the VM window, but when I click it, it gives me 3 errors in a row:

Could not open /dev/vmmon: Broken pipe. Please make sure that the kernel module `vmmon’ is loaded.

Failed to initialize monitor device.

Transport (VMDB) error -14: Pipe connection has been broken

Please help? Thank you!

The error is telling you that VMWare is not being allowed to display on your screen.

1. Always the first thing to try: reboot after installing VMWare, then try the play button again (because it installs low-level extensions to MacOS that will only be activated when the computer boots)

2. If you have VirtualBox installed (from previous testing that we asked you to do), uninstall it, then reboot (and possibly even re-install VMWare + reboot again, just to be sure!)

3. VMWare should have prompted you to agree to a kernel extension when you installed it, but this dialogue box doesn’t always appear. So, go to System Preferences (on your Mac) – Security & Privacy – General and look for something to click to agree to VMWare. As well as the General tab, look in the Privacy tab and find all the places where you can tick VMWare (e.g., Full Disk Access)

Thank you so much! Everything’s (I hope) working now, I also tried this solution I found on the VMWare forums, I had to do something weird because I didn’t have the allow options in my Security and Privacy > General.

Here’s the link for anyone else who gets this issue!
