Nope, after the latest round of updates "My Mac" no longer appears for my OSX application project. So frustrating! Not sure if this is from the Ventura 13.3.1 update or the XCode 14.3 update, I just did both.
... (edit) ...
Probably XCode 14.3 - my old MacBook Pro is also on OSX 13.3.1, but XCode 14.2, and I can still run on "My Mac" there. (It's either that or something to do with the old intel chip, I suppose.)
