Ejecting the virtual media after usage causes macOS 15.6 to show the loading cursor icon and freeze:
The macOS UI becomes unresponsive, and it is required to restart the machine to solve the issue.

The issue happens 90% of the time.

I wasn’t able to reproduce this issue on 15.3.1 (M1 Pro) or 15.7 (M4 Max), but I did notice something more interesting. the OS doesn’t allow me to eject the image. The eject function works fine when the controlled device is Windows.

Could you please share the logs from /userdata/jetkvm/last.log when you attempt to eject the image?
That would be very helpful for troubleshooting. If you prefer not to share the logs publicly, you can send them to siyuan+issue730#buildjet.com.
