Q: Unable to "Prepare library". Status bar stuck at 55%

I started Photos for the first time and system started the "preparing Library" process. It ran for about 20 minutes and froze. Photos does not allow a user to exit the program during this process so a hard restart is the only way to unfreeze the system. I made 3 attempts including letting the process run for more than 24 hours and it still hangs at 55% complete. Any ideas?

iCLOUD, Mac OS X (10.6.8)
