I couldn't understand why, since About This Mac shows that there's 2.07 TB available. I discovered the problem when I was trying to import FinalCut Pro media and it gave me the error that there wasn't enough space on my local hard drive. Combined with the regular data, it says I've used up 3.98 TB of my 4 TB hard drive. Why does my Mac HD have over 2 TB of purgeable data when I've only used 1.7 TB of regular data? I'm trying to understand why my Mac HD is showing 2.04 TB of purgeable data. These total 13 GB on this MB pro and would seem to be correct. Is it /System folder plus /Libray folder. QUESTION: When Storage reports that the System is X size, what folders are used to arrive at this sum? If I know that for sure, I can go in and add them up and come up with an accurate size. Why does About this Mac show the System software taking up 54.05 GB of data? The /System folder contains 6.76 GB of data. However, even after installing a fresh copy of Mojave today, when I do an About this Mac > Storage > and hover my cursor over the gray section of the bar, it show: System 54.05 GB.Ĭhecking my folders individually,I discovered that: I booted up in Recovery mode, erased the HD, installed a fresh copy of Mojave and migrated my data from a clone of my old MB pro. System Software is 53GB out of 250 GB HD I took over a 2012 MB Pro, 15' Retina from someone who upgraded to a new 16' MB Pro. But I moved those to my external drive.Īny one got any concrete ideas and what can I try? I think I sudden realize my 512 GB HD has alot of free space to little. I aways upgrade to the latest OS on the day it releases or maybe 1 week at the most. Have been trying to upgrade xCode for months now, no success. The free version of Clean MyMac X didn't do much except save me 5 GB.Delete local versions of timemachine backup via 'tmutil listlocalsnapshotdates and deletelocalsnapshotdates.Took a look at Storage, and rebooted in normal node. I always keep my ~/Libraries/Application Support, Logs, Caches, clean,.Cleaned up my Download folder of old *.dmg, *.pkg, *.zip and other larger files.Move my iOS backups to an external drive.Removed some applications, including Xcode.Gained some disk space back but the System Data has not budge at all.

I've tried alot of things to reduce the storage on my HD. Left Top Apple Icon -> About This Mac -> Storage.
