My main question is how do I get my iPhoto library back on my Mac ? I’m was running macOS High Sierra Public Beta 1 And I started getting a constant restart saying ‘your computer restarted because of a problem. The log shows there is a panic report with the kernel trap. The only way out of the restart was to downgrade out of the Beta version onto the Mac OS High Sierra. I’m happy to stop running the Beta version, if it means my Mac works normally as doesn’t keep asking to restart. I now find my iPhoto library has gone and saying ‘unsupported library create a new library?' All my photos are on my iPhone and in the iCloud so nothing lost. Is there a way to get my full library of photos back on my Mac without losing anything ?
