Updating virtualized macOS, particularly on M1 Macs, has been challenging for some users like Howard Oakley.Attempts to update from version 15.3.2 to 15.4.1 on the M1 Pro resulted in a kernel panic and failure.The macOS 15.4.1 update seems to have resolved issues with real macOS installations but not with virtual machines.Users with existing VMs of Sequoia versions prior to 15.4 might face difficulties updating to 15.4 or later on an M1 host.
