[Solved] "System" is using lots of Disk Space on Mojave and High Sierra
Like @johnfbraun mentioned in a recent episode, I've now started seeing "System" using over 100GB on my APFS-formatted High Sierra and Mojave systems. I've been running all kinds of utilities to find the answer, to little/no avail.
This morning, with DaisyDisk, I realized that my Drive Genius logs were taking up ~20GB. Those were mostly in ~/Library/Logs/com_prosofteng_logs/DriveGenius/dp. I don't launch Drive Genius often these days, so I assume these are from its Drive Pulse app (which I'm not keen on anyway). I opened that folder and saw a few very large .tlg files in there. Before just manually deleting them, I launched Drive Genius... and watched it wipe them away.
Perhaps Drive Genius is built to "process" these, but only after launch?
Anyway, that's one small dent in my System Storage usage (I still have 152GB used there). What have you found that helps?
