If you run macOS virtual machines (VMs) on Apple silicon Macs using lightweight virtualisation, you may wish to […]
Apple claims that its macOS VMs can run Metal and deliver “great graphics performance”. How could you assess that, and are they really that good?
Code run in a lightweight Virtual Machine can’t take advantage of the Efficiency cores of the host Apple silicon Mac. How then does Sonoma handle its threads?
Once the virtualisation app has configured a VM to be run, it starts it, and stands back as the macOS Virtual Machine Service does all the hard work.
How to run apps on the host, access iCloud Drive, and get faster file write performance in a macOS VM. And why Spotlight is limited, and the Force Quit dialog a bit odd.
Using lsregister to clean up the Open With menu only works temporarily, and it’s populated by apps found anywhere local to your Mac. That’s not good for VMs sharing the Applications folder.
