I noticed after the mavericks install that it free'd up about 15GB's of space on my crucial ssd. All my other apps and everything else is still there. I have my iTunes library on a different drive.

Anyone else notice this?

Regained hard drive space after installing Mavericks

I regained almost 200 GB after installing Mavericks. Does anybody know why?

I did a clean install of Mavericks,

to my surprise, this OSX only took about 10 GB of space.

I believe ML took 15 GB.

so Mavericks is a lot leaner :)

Me too

Added >100 GB free space to the HD of my 2012 Retina MBA 15". Persisted through a couple restarts. I don't find anything missing so I can't figure out what happened, but I'm grateful for the extra space.

Updated from GM v1 last night and lost about 10 GBs after a clean install and migration from a time machine backup using Migration Assistant.

No idea why this would be the case, but it happened.

To those who gained space:

Was it a clean install or typical app store install?

Yeah I got lots of space from the update as well, which is awesome! At first I thought it deleted some of my stuff haha. I need all the space I can get with an SSD. I just did it straight from the App Store no clean install.

What I want to know is, where was all this wasted space on the HD, and if it fills up again, how to clean it up without waiting for the next version of Mac OS to do it for us?

I think it was actually an essential part of OS X. Probably don't have to worry about it again. At least I hope not :p

There are a few things that my cause this.

1. Most caches are cleared after installing a new OS. Caches may become quit big after a few months of usage, up to a few GB's.

2. Your hibernation file is deleted after installing a new OS. The hibernation file is used by OSX to store the contents of you memory when you put your mac to sleep for a function called "safe sleep". In case of a power outage your RAM is cleared so your mac will resume from hibernation instead of sleep. So after you put your mac to sleep for the first time, the entire contents of your memory is stored on your disk including the empty space. If you have 8gb of memory installed you will have a hibernation file of 8gb on your disk.

3. In Mountain Lion, Apple has updated Time Machine so it will make local backups while your not connected to you backup-disk. It will keep these backups on your disk until the disk becomes too full so they can become huge. The moment you connect your mac to your backup-disk it will write all these backups to your backup-disk so you won't lose any backup. Chances are you made sure you have a working backup on your backup-disk before you upgraded to mavericks and so your local backups have been cleared.

Just to update:


I did a clean install after feeling like I lost a lot of space that I could not recover.

After the clean install I gained 17 gigs of space !

I don't know exactly why but thats what it is...
