Back on August 7/22 I bought Parallels Desktop 17 for my Macbook M1 Pro , secretly these people knew it didn't work with Macbook M1 Pro, they knew it had problems . I could not get them to tell me it didn't until they had danced me around for days until suddenly they turn around and say Desktop 18 works for Macbook M1 Pro but they put a deadline that meant I was 8 days too late to get a free upgrade. I finally said I wanted a refund but now its a couple days too late for a refund for this failure of an app. Worst company ever.
