Unable to Update Virtualized macOS
I have since tried updating my 15.3.2 VM to 15.4.1 on the M4 Pro, a surprisingly large update of over 6 GB, and that continues to result in a kernel panic and failure. I have also tried updating from 15.1 to 15.4.1 with an extraordinarily large download of more than 15 GB, only to see a repeat of the same kernel panic, with an almost identical panic log.
The macOS 15.4 update was particularly large, and some Apple silicon Macs were unable to install it successfully, most commonly on external bootable disks. From your reports, the 15.4.1 update seems to have fixed those problems with real rather than virtualised macOS. However, it hasn’t done anything to solve problems with VMs.
If you have an existing VM running any version of Sequoia prior to 15.4, then you’re unlikely to be successful updating that to 15.4 or later using an M4 host.
