Since I upgraded to macOS High Sierra, one week ago, I have noticed that each time I wake the computer from sleep, the space left on the drive have decreased by a, somewhat, random amount.
I have very little free space on my drive - too little actually - so I usually keep an eye on it during each session I'm using the computer.
My first notice was that the assumed left space of about 6GB was only about 5. The day after the space was down to ~150MB! I did some cleanup, removed Xcode derived data, cleaned out cashes etc, and restarted. I think I got back to about 3-4GB.
Fast forward to the day before yesterday. Then I cleaned out a lot of junk and I had about 17GB of free space. Yesterday I only had just below 16GB, and today I only have ~10GB. After a reboot I got 12.5GB, but I also removed about maybe a 500MB yesterday, so I should at least have more than 16GB if everything was working the way I was expecting it.
What I have tried to 'solve' the problem is to see if closing apps increases the space - and it does - but not that much so I regain all 'lost' space. I also cleaned out cashes and Xcode derived data. But since I did this the first time, there is usually not much of a gain here.
I have a MBP Retina, i7, with 16GB of memory and ~500GB of disk. The computer is from 2013, I think. I regularly use Xcode, Safari, iTunes, Messages. Sometimes also Affinity Photo, Aurora HDR, Luminar and qbittorrent.
Searching on google, it seems like I'm the only one having this kind of problem. Or is there someone else having similar issues with decreasing space on the drive?
All help on this issue is welcome!
