I switched to OpenSUSE from Fedora 38. This was back in Nov 2023. Had used fedora for around 1 yr or so and used opensuse after that for few months before I finally switched to Debian.
Yeah it was tough to install it on MBP 2012. Before this particular installation i already had tried to install it once or twice and failed due to some bootloader / grub efi issue.
But i came back after months and tried to get feel of KDE on it. Its good but package manager and software repos are very niche. Not easy to find some apps in repos and u can always install from .tar ball but i dont like that approach. So i hoped to another disteo. YaST tools are awesome. It was the package manager / repo why i switched not KDE itself.
