i am trying to use the sudo trimforce enable command in terminal. It goes through the motions like it's enabling trim, but it is not showing that trim support is on. I have a Samsung 850 Pro SSD and it has always worked on prior OSes. Anyone know about this?
Has anyone been able to enable trim on 10.13?
I have two installations. One was an upgrade, the other a fresh install. Trim works on both.
And you ran the "sudo trimforce enable" in terminal and are getting a Trim Support "Yes" in About This Mac -> System Report?
I just double checked and it is indeed broken in Beta 4!
The command runs correctly, but trim never shows after reboot. Even disabling SIP does not fix it.
Bug filed.
For now I am using Disk Sensei to force trim. It works and does so without disabling SIP.
Thanks!! Hopefully it will get fixed in the next release.
Hi do you have the bug number? This is a serious bug that can't wait two weeks or however long for the next beta. My machine has been gradually losing disk space since installing beta 4 and I now have less than 40GB remaining from over 100GB 5 days ago. I'll run into problems or run out of disk space before the next beta release - assuming it even includes a fix - rendering my machine inoperable. I think this needs an emergency fix as a priority. Unless someone can suggest a 'safe' workaround? I'm running an Apple SSD which says trim is enabled. Is Disk Sensei okay to use in this instance?
Lack of Trim does not impact free space. It enhances SSD internal free space recovery performance mainly noticable in high disk utilization scenarios. The OS provides a list of freed sectors to the SSD, which might elect to use that information in its idle time erase routines. In most cases, you would not really notice unless you time write operations.
It does not have any effect on free list of HFS Plus APFS - e.g. the free space reported.
I would recommend looking into where the disk space is gobbled up - logs, core dumps, VM files, temp files?
Well it still doesn't work on Beta 5. Just ran it and restarted and Trim is marked as "No"
Did you try again to enable it?
My Disk Sensei forced trim survived several Beta 5 reinstinalls.
Yes, I tried Disk Sensei and it says "Trim is enabled but not working" and tells me it's either incompatible or I need to restart. Neither of those things are true. It will let me trim the drives manually so I will just wait ujtil they fix it.
Same here with a Mac Mini that has both a user replaced internal SSD and external SSDs via Thunderbolt 2. All of the drives were showing trim enabled prior to installation of the 10.13 beta today.
Well it still doesn't work in Beta 6 - at least the terminal command activation.
Confirmed not working in Beta 6.
As a work around, I am using Disk Sensei, which installs a Trimenabler extension and that is working.
There is also a free Trimenabler that provides the same capability for free. Other features of the app require payment.
