MacOS High Sierra (10.13): Trim working?

Trim does not initially change performance at all, what is does Is to help prevent a severe loss of performance by avoiding the SSD getting clogged up with usable cells.

As best as we can tell, yes, it does the same thing as Trim Enabler

Thats odd, I do see Trim Enabled every time I set up a Mac with this command. . The exact command I have been using in Terminal is:
"sudo trimforce enable"
and it works fine for me.

Are you running MacOs High Sierra 10.13.3?
 
Then I do not know why it doesn't appear under SATA/SATA Express........
[doublepost=1518832514][/doublepost]Is there a terminal command to verify if Trim is enabled.

I did run the following command and seemed to work fine (sudo trimforce enable) but no evidence of it in the System Information.

Thats so weird, you don't show any drive as being mounted to the SATA bus. So odd! What drive is your machine booting from?

This command works for me
system_profiler SPSerialATADataType | grep 'TRIM'

If TRIM is on them you will get this response: "TRIM Support: Yes"
 
Booting from the main hard drive....computer is a month old 27 inch/Retina 5K/i7 4.2 GHZ/ 1TB SSD......with 40GB RAM...

Tried that command and did not get the Trim infro

I also have a 1TB SSD. This truly is baffling. Do you have another Mac that you can try it on?

This is what I get when I run it:
Bobs-MacBook-Pro:~ bob$ system_profiler SPSerialATADataType | grep 'TRIM'

TRIM Support: Yes

Bobs-MacBook-Pro:~ bob$
 
I have 3 iMacs but only one with SSD the others have a 1TB rotational drive and 1TB Fusion drive.....
[doublepost=1518835740][/doublepost]Can I run the trim command on the fusion drive?

At the moment the command is disabled on Fusion drives. I was available for a while in the early Beta but then it was pulled and is still not available as far as I know.

Here is a screenshot of what mine looks like. You can see my SSD drive and its characteristics.

I am also baffled no sure why my System profiler does not show that info......I wonder if there is a terminal command to make that info populate.
[doublepost=1518836418][/doublepost]I found the Trim info not under SATA/SATA Express but under NVMExpress.....

OH!!! You have an Apple SSD! The Trimforce command is not needed because Apple SSDs automatically get Trim to be enabled, there is no need to use TrimFORCE to Force it to be on! LOL

The reason you see the drive there is because the Apple SSDs are NVMe drives, nor SATA drives.

It looks like you are fine, Trimforce is relevant for you.
 
So I enabled what was already enabled......nothing like spinning ones wheels.....but at least I learned something......
 
Hey. I Have a question.

Years ago, when I used @Cindori Trim Enabler, I remember I had to deactivate TRIM before I formatt or update the system, because otherwise I could brick my macbook pro with a forbidden symbol.

Now, with the use of TRIMFORCE command, I don't se Cindori's tool anymore, and I ask myself if I need to deactivate TRIMFORCE each time I'm going to formatt or update my system.

Thank you.

I have not turned off Trimforce ever since invoking it a long time ago. There have been many updates since then and I have not experienced any problems on any of my machines.

Even major updates? I mean, from Sierra to High Sierra for instance.

Between Major updates I experienced no problems at all, but I did have to re-issue the Trimforce command again because was not enabled by default for my non-Apple SSDs.
 
Hi guys,

Just updated to High Sierra from Sierra today. I've immediately noticed slow boot times since the upgrade. I previously had TRIM enabled on my Samsung EVO 850 SSD using the Disk Sensei app, however System Report seems to show TRIM Support as "No".

I'd like to re-enable TRIM but my trial period for the Disk Sensei app has now ended. Any other way I could do this?

Thank you!

Entering the line below in Terminal should do the trick.

Code: 
sudo trimforce enable

You will be prompted for your password.

If you had looked at the very first post on this page you would have gotten the same answer as supplied by Weaselboy. Also you could buy Disk Sensei or Trim Enabler. just a thought.
