My LR 2.6 install has worked fine for years on my black Mac, running 10.6.8. It suddenly pushes my CPU to overdrive, my fan kicks on and it will neither load libraries or finish creating new ones. It will not completely load despite waiting forever... literally. Any ideas? Anyone. I have years of libraries that I can't open right now. I have rebooted, force killed, etc.. I have not reloaded the app from scratch (last resort).
Any error message? Or part of Lightroom appears to open but it doesn't finish? what does happen? Or just nothing happens?
Reinstalling and renaming the preferences file to something else so LR creates a new one are the two suggestions I'd have.
It sounds like the software equivalent of a heart attack in old age! My prescription would be LR 5.7 used daily.
