I've spent the past day and a half restoring my mac (osX 10.5.5) to working condition. Yesterday I dumped thousand of fonts into ~Library/Fonts. My system became unstable. I tried using Linotype FontExplorer X to turn off all but 1000 fonts, but my mac was still hosed. Certain apps would crash as soon as they started. I used TIme Machine to restore that directory to its prior state, and now I'm back in working condition.
I would love to have all of these fonts as a resource. How do I use them without causing problems for my mac?
