Latest Geekbench performance figures for macOS VMs, and testing of how few cores and how little memory is really needed: could you run a macOS VM usefully on a MacBook Neo?
Virtualising macOS, Linux and Windows on Intel Macs has been relatively straightforward, and device support left to the developer. That won’t work for Apple silicon Macs. This explains what happens, its strengths and limitations as a result.
In Ventura, VM disk performance was poor, with write speeds of 0.7 GB/s. How fast is it now in macOS 26.4, and how does using FileVault affect it? Plus a note on problems with BSIs in VMs.
Doesn’t macOS wear out internal SSDs quickly because of all the data it writes to them? Will my Mac’s SSD wear out prematurely? How can I tell?
