Therefore, you can safely delete everything in ~/Library. Cmd/double click that & repeat the process.įrom what is in /System/Library/User Template/Library, here is what ~/Library contains when you create a brand new user.Īlmost all entries are empty directories.Application Support is usually the largest by quite some margin, so.Back in the ~/Lib folder, set to sort by Size from the column headers.Hit Cmd/J for View Options & set to 'Calculate all sizes'.Open the ~/Library folder, set to List View.If someone remembers & drops it in comments, that would be very nice)Īnother way to hone down the largest users would be. (There's another similar tool I can't right now remember the name of. I'd still be very, very careful in there, but maybe try something like Grand Perspective to see what the largest users are. That said, some apps can store large cache files in there, others may be folders for apps you long-since deleted - those would be safe candidates.ħ0GB is a pretty big lib, btw, mine is only 30GB & I'm a heavy user.
It would generally be unwise to start playing in there without being certain of what you are doing. ~/Library is where all your apps store their prefs, how you want them to work for you. However, with it being a somewhat loaded dev machine, I was surprised to find that the system was surprisingly tolerant of the complete removal of ~/Library. In my case the user account was not valued and the machine was pending complete format. I understand that this could be a hugely risky move depending on what applications are installed and your level of comfort with losing data/time. After all settings were back in place, a df -h showed that I reclaimed about 16GB. The system survived and is still running great. Upon boot I had to log back into iCloud, set up Slack, set preferences on keyboard, trackpad, terminal, browser, programs, etc. I didn't expect that the system would return to an operational state.

Having planned on performing a fresh install anyway, I further experimented by rming the entire ~/Library directory and rebooting. In the Mail sidebar, Control-click a Bin mailbox, then choose Erase Deleted Items. In the Mail app on your Mac, do one of the following: Choose Mailbox > Erase Deleted Items, then choose an account. I began experimenting with ~/Library to reduce bloat on a system where HDD space was running low. indicates that there are 3.2Gb of deleted mail items, which are still not removed from the drive.

While developing BLE applications on 10.11.x versions of Mac OS, I often found that I had to clear BLE data from ~/Library in order to return to a pre-connected/paired state on server (not client) devices. This question is a bit old now, but I figured I'd add my experience for googling.
