I tried creating a tech support ticket but after two attempts, the system is not showing any tickets.
Mac OS 10.10.1
Progress bar is always greater than 100%, actually stuck at exactly 170% for about an hour, despite files being scanned.
The screenshot says it all.
EDIT:
After several hours at 170%, now it's stuck at 198%... wondering if/when this scan will ever finish... 4 hours, 20 minutes and counting.
