System uses ~300GB

After upgrading to 10.13, my 500GB SSD is nearly full. With 10.12 i always had ~200GB free. Looking at AboutThisMac->Storage->Manage, i see "System" using up nearly 300GB. However, looking at my SSD in finder, i cannot see any folders that would sum up to this size.


Does anyone notice this as well and is there a workaround?

Here's a "working fix":


  • Revert to Seirra via TimeMachine backup
  • Upgrade to High Seierra Beta 2 directly by checking convert to APFS


Tried adding/deleting couple large files and the disk space seems to be released properly, so far 🙂

Yes, Beta 2 seems better. Still keeping a close eye though - I was down to less than 1.5GB before I took drastic action

You mean "unchecking" convert to APFS. APFS is the problem at the moment.

he means "checking" from Sierra strait to High Sierra Beta 2.

So convert from HFS to APFS but using Beta 2 instead of Beta 1? Is this confirmd by others?

No, I meant "checking." APFS works as expected in reclaiming spaces in beta 2. I've tried quite some large files adding/deleting, disk space has been properly reclaimed 🙂

My experience to date is that APFS in Beta 2 does *not* exhibit this problem. I am keeping constantly refreshed backups via Carbon Copy Cloner and I still have my little magic USB installer becasue, well. you know.


However, since I reformstted and installed Beat 2, free space has remained around 55GB, so looking good so far

My experience too

Try deleting something large. This all started when my computer crashed. I'm wondering if my partition is somehow corrupted and APFS is unable to handle it. (Even though I can succesfully get through a First Aid.)

Beta 2 update 1 is still exhibiting this problem on my test machine. It's down to just over 3GB of free space with a System folder of over 130GB and growing every time I delete a file and empty the trash.


Bug report submitted!

Have you upgraded to APFS with Beta 2 Update 1 or before this release?

I think update doesn't fix problem if it already happened but prevents it to happen after installing.

Has anyone found a solution besides erasing and reinstalling? I noticed after Beta 2, my storage climbed a little bit.

I then tried installing public beta over it and since then, it has actually went down, probably because of the public download file but it looks like it was removed after the install.

If you do erase, can you restore from backup or do you need to start clean?


Anyone that is on Beta 2 after reinstalling, can you confirm your storage has not disappeared again?

First came here as my Time Machine 6TB volume in my Pegasus R4 array began having difficulties backing up my drives, which has never happened. I converted my volumes to APFS and made certain Time Machine is still HFS+ Journaled. Oddly, all APFS drives are greyed out and backing up is not working at all. Booted into safe mode, ran fsck on every volume, found some errors, made corrections, deleted an local snapshots (found two) and followed a number of suggestions from this thread (thanks!).


While reading I noticed the biggest issue is drive space being eaten away. Im sure this is not the problem but just in case, I had the very same issues on my current gen Mac Pro6,1 SSD. Turns out iCloud Drive was eating up my boot volume as "Store in iCloud" under "Storage" in "System Information" was turned on and was downloading files from my iTunes Library and Photos including any iCloud documents. I was panicking as GB's of data were disappearing in front of my eyes. Once I turned it off, all the space was freed and the amount of data returned to the usual range I am used to seeing.


Again, doubt this is the issue as it's too obvious and from what I gathered this goes deeper with issues between APFS and HFS+ (Journaled Extended) volumes. My issue is not being able to use any drive, my usual 6TB drive in my R4 array or any other attached drive formatted for Time Machine. It recognizes the volume, but under "Options" all of my hard drive including the boot drive that are now APFS are greyed out. If anyone has any advice I'd greatly appreciate it. Thanks!

Those steps saved my ***. Worked perfectly, and my restored CCC backup now shows the proper amount of free space on my internal drive.

After I had all the same issues of above, I did the following which solved all problems for me:

1. Made a backup with CCC

2. Removed my Samsung 850 EVO 1TB and did a Low Level Format on my Windows Server ( Low Level Format Tool)

3. Then formatted new HFS+

4. Replaced the SSD and booted with HIGH SIERRA DP1 Bootstick to do an absolut clean install.

5. After Configuration of iCloud, Apple ID and Networksettings updated Step by Step to DP 2.1. Enabling TRIM again.

6. Manually bring the files from Clone-backup back to the system


System was at about 18GB after this procedere and now during installations growing normally to 45GB. When I compare to my imac this seems to be correct. There it is at about 140GB..


There are no Backlight problems. Slow booting seems to be gone. System works very smooth without Fan overload.

The main problem I think is the conversion of the old used HFS+ to APFS and/or the enabled Trim.


When the work is over I will come back again and tell the last experiences belonging boot sequence time.


Only must get the machine MBP 13" late 2010 to active directory.
