TFA does not contain the word "copy", but copy-paste (shared clipboard) support stands out strongly to me as being "different" in Apple Silicon virtualization at this time.

TFA does mention the word "clipboard", but the containing sentence, while perhaps technically correct, seems a bit misleading, as follows: "As implemented in macOS (both as guest and host), there are also extensions to support keyboard and pointing devices, a shared clipboard, and high-performance graphics with Metal and GPU support." As I understand it, even if those extensions "exist", what good are they if they are not adopted?:

- If you virtualize macOS within macOS on Apple Silicon using UTM, you cannot copy paste between systems reliably (bidirectional shared clipboard is very, very fragile; "can" work a little but is essentially fully broken/unreliable).

- If you virtualize macOS within macOS on Apple Silicon using Parallels (often considered a best-choice solution), you cannot copy paste between systems at all (bidirectional shared clipboard is an explicit non-feature at this time).

Thus, if you want bidirectional clipboard, on a macOS host, you'll have to run a *nix (seems to work) or maybe Win (I haven't tried) guest OS.

I would have tried VMWare Fusion (free for personal use), but after jumping through all the signup and download navigation hoops, I couldn't even get the download link to un-gray itself out for me. Is bidirectional macOS to macOS clipboard implemented there? IDK and I cannot tell.
