Snow Leopard Server stops working with Parallels 26 upgrade. I upgraded Parallels from 20.4.1 to 26 and my Snow Leopard (MacOS 10.6) no longer boots.
I see that I am still being shadow-banned by Parallels for pointing out that their software phones home to a Chinese website. Seriously?!!!
Same problem...!!! Same upgrade from 20.4.1 to 26.1.2 (Parallels). iMac Retina 5K 2019, Intel Core i5, SSD 1 To and 40 Go RAM. Is there something to do ??? No problem with others VM (Windows 10, Debian 13, Ubuntu, MacOS X Mojave).
Same problem: "UEFI Interactive Shell v2.2" ... I upgraded Parallels from 20.4.1 to 26.2.0 and 26.1.1 and 26.1.0 on Intel and my Snow Leopard (MacOS 10.6.8) no longer booted. However, my Snow Leopard VM booted again after I downgraded Parallels by installing version 20.4.1 which you can download here: https://download.parallels.com/desktop/v20/20.4.1-55996/ParallelsDesktop-20.4.1-55996.dmg . Until Parallels fixes their version 26.x, version 20.4.1 seems to be the last version that works with Snow Leopard. I hope this helps you too. You might need to reenter your Parallels license key (I didn't)
For what it's worth my Intel mac host runs MacOS Sequoia Version 15.7.3 (not the current Tahoe vs 26.2)
