Can some you share a light in the use and applicability of MacOS (15.X) on Parallels 20 on M4? Note that W11 (ARM) supports X86, even some old software works. For MacOS (older none silicon versions are not supported). The App Store seems not workable due to limitations (experienced, and noted in KBs), x86 versions of MacOS or Windows 10 are not use able (experienced, pro has experimental support for x86 but I did not get it to work - others has same experience). XCode (did not try it myself) I read is not usable... due to Apple restrictions - leaves the question, please clarify, what is the purpose of Parallels 20 in M4 ?
