TLDR: macOS virtualization is as fast as native due to hypervisor support, with free but limited driver support thanks to virtio. MacOS guests are limited to 2 at a time, and cannot use iCloud services or log in to the App Store.
Also FYI:
- launch times are fast enough for serverless
- you can restore snapshots for macOS guests but not for Linux
- Apple's open-source container support is built on Virtualization, making it a much more secure option than Docker
What's needs investigating is access to the secure enclave. You can login with an apple ID and use enclave API's; it's not clear if this is emulated or handled using the host enclave with a different scope - i.e., if this presents any security issues. To be conservative, one might avoid logging in using an Apple ID with sensitive information in an automated/CI context.
- thisislife2 6mo agoFor me the key point was how the frog is slowly being boiled and macOS is being converted slowly to ios / iPadOS with increasing restrictions. Case in point, now system developers cannot build and sell custom virtualisation solutions for Macs: > For vendors like VMware and Parallels ... there’s no scope for either of them to engineer better or faster graphics support, as that’s determined by features provided in both guest and host operating systems, via Virtio or an equivalent. That puts Apple in charge of what hardware and features are supported by virtualisation on Apple silicon.
