Mac System Data is large This question pops up alot. Can't find anything to help. Left Top Apple Icon -> About This Mac -> Storage. Shows System Data at 325 GB. I've tried alot of things to reduce the storage on my HD. Gained some disk space back but the System Data has not budge at all. Where's what I've done: Removed some applications, including Xcode Move my iOS backups to an external drive Cleaned up my Download folder of old *.dmg, *.pkg, *.zip and other larger files. I always keep my ~/Libraries/Application Support, Logs, Caches, clean, Rebooted into Safe Mode. Took a look at Storage, and rebooted in normal node. Delete local versions of timemachine backup via 'tmutil listlocalsnapshotdates and deletelocalsnapshotdates. The free version of Clean MyMac X didn't do much except save me 5 GB. Have been trying to upgrade xCode for months now, no success. In the meantime the OS has been updated. I aways upgrade to the latest OS on the day it releases or maybe 1 week at the most. I think I sudden realize my 512 GB HD has alot of free space to little. Thought it was videos and music. But I moved those to my external drive. Any one got any concrete ideas and what can I try? Thanks. [Re-Titled by Moderator]
