No VM can start after quitting and starting UTM again #7583
Description
Describe the issue
From a cold boot, everything works fine. After a first use of UTM and it VMs everything is closed properly, including UTM.
Then, after starting UTM again no one of all the VMs can start. The VM console is black and it shows the spinning wheel forever. The windows has to be closed and the QUEMULauncher process has to be killed manually.
The only way to make UTM work again is rebooting the machine.
This only happens after upgrading macOS from version 15 Sequoia to version 16 Tahoe.
Configuration
- UTM Version: 4.7.5, also tried 5.0.0 beta with the same result
- macOS Version: 26.2
- Mac Chip: M1 Pro (MacBookPro18,3)
Crash log
There is no crash.
Debug log
This is an example from one VM, all of them show the same behaviour, whatever the guest OS and its configuration (based on the defaults for the guest), be it Linux, Windows or other (FreeBSD at the moment).
