Before I upgraded I cleaned my harddrive a bit and had 50Gb free. I updated smoothly without issue. The next day I received an alert telling me I had limited harddrive space. I checked the 'get info' menu on my harddrive icon and it said I had 756 Mb. I deleted some more things, leaving me at 6Gb and then watched my harddrive space disappear. I immediately disabled versions in the Time Machine Preferences. After disabling versions I got the previous 6Gb back but I'm still missing the original 50Gb. I ran a time machine backup after finding some info that backing it up will clear the space but it did not. Anyone have any ideas how I can get the 50Gbs of space back?
