Suddenly I have more hard drive space?

[dgerch]

After I downloaded Yosemite I noticed my hard drive went from having about 93 Gigs of free space to almost 104? How did I suddenly free up about 11 gigs of hard drive space? Has this happened to anything else? What was deleted?

I seem to have gain more or less the same as you. Maybe they deleted some unused system files?

224gb before the update and 232 after the update mba mid 2013

Same here...gained about 3 GB. At first I thought I was imagining my increase in HD space. Iʻll take it though...

I gained about 7 gig

One of my MacBooks - a mid 2012 air with only 64 GB RAM went from about 2 gig free to over 9. I'm happy. But still need to increase drive. 25gb is lost in the system files.

I noticed a sizable increase too.

I had about the same increase as well. Compression built in possibly?

Going from ML to Mavericks had exact same effect, more disk space available.

Yup I went from 9gb to 20gb. I was wondering maybe it's all the caches from general usage that was removed..

I did an update to trim and either because of the author (more likely an OS X change) the hibernate file is now disabled by default...that would account for the increased hard disk space. Can anyone confirm?

Same here. Upgrading to Yosemite seems to have freed up about 10gb of space on my macbook air and iMac.

Gained 20 gigs from fresh install to time machine recovery
