My initial experience was horrible with Sonoma. A brand new iMac M3 maxed out. I never migrated any data. No Time Machine migration. Everything was on iCloud. Files, iCloud mail account. Seriously, I copied nothing from any drive. Soon as I started to set it up, it asked to be updated to Sonoma, since it shipped with Ventura. Soon as it finished the Magic Trackpad was all over the place, stuttering, jumping, pausing. It was getting worse, so I did a safe boot after and it helped. Then the ejects of external SSD was happening. Then Quicktime just froze combining some mov files into one. The screen turned pinked and the iMac shut down and rebooted. Oh yeah the keyboard and trackpad disconnected and had to be reconnected manually. I did another safe boot later. Then Mail started to just expectedly quit on its own randomly. I only have one mail account "iCloud". So then I ended up Reinstalling Mac OS. That improved Magic Trackpad a lot, but Mail still keep crashing. I finally had it and just Erase All Contents and Settings start all over again. NO Migration from any drive since I have iCloud everything. Updated to 14.5 , now I only have the sudden eject of SSD USB drive (not often but can happen), and Pages locking up once and forcing it to quit. I did another Safe boot to clear up cache and this is where I'm at. Maybe 14.5 will stay stable. If I was a new Apple customer I would have been extremely disappointed and regret the purchase. I've experienced worse with Apple stuff so I deal with it and fix what I can. Anyway Sonoma was terrible for my initial experience with it.
