Hi Mikhail,
Let me first tell you that this statement "Parallels Desktop 19 isn't supported to run on Mac computers with macOS 15 as a main system" it's completely inaccurate;
I was using version 19 until last week with my previous mac mini (M2 pro) and macOS 15 installed on it.; all virtual machines were working without any issue; hence, it's NOT macOS 15 the issue but something with the new processor M4.
Additionally, I'm STILL using version 19 on my macBook Pro M3 Pro with macOS 15 installed (See attached picture)
I have been using Parallels for years, but lately I've noticed that you guys don't support previous versions almost immediately something happens (update macOS or issues with new processors).
If you are not guaranteeing supporting your products for "perpetual licenses" why you don't stop to sell them and only offer what you are willing to support ?
I found this completely disconsidered behavior to ask us (your customer) to pay for "upgrades" every year. (in my case 2 licenses)
At least, this time, since this nothing to do with macOS, should offer us another option that just "buy" the new version.
Please let us know if you definitely won't patch version 19 and no other option will be offer but just pay for the upgrade.
Thanks,
Fred
