TRIM with Maverick

[chobailey]

Anyone having issues with enabling TRIM with the new update? I installed the TRIM kext in multibeast, but my systems still shows no TRIM for my SSD.

For me I've Checked Trim support in Multibeast and it works.
Use Trim Enabler.app

Where can you check if trim is working?

 

[oswaldm]

About This Mac -> More Info... -> System Report -> (from the left panel) SATA/SATA Express

And then you click the name of your disk and among the list there is TRIM Support status.

Thanks, it looks like trim is working for me but I installed the kext for it with multibeast when I did my install

same problem I've met
multibeast 6.0.0 with Cosair CSSD-F60GB2

tried trim enabler.app (version 3.1.2), failed at mavericks' boot

Try Chameleon SSD Optimizer. Many people prefer it to Trim Enabler.

Try Chameleon SSD Optimizer. Many people prefer it to Trim Enabler.

I am trying to enable trim on my Samsung SSD and methods by Multibeast and Chameleon SSD optimizer did not work. What else I can try?

Thanks in advance.

Trim Enabler 3.2.2 worked for me. 3.2.4 is the current version.

[FONT=Verdana, serif]youshouldn't see any output. If you do see some warning message sayingabout the IOAHCIBlockStorage file being corrupted or something, youhave to ABORT! Replace the modified file with the backup of theoriginal, and re-do this step. If you go on to restart, you'll mostlikely end up with a non-booting system (it will still be possible torecover, but it's more trouble - see bottom of this post)[/FONT]

[FONT=Verdana, serif]Thisdepends on whether a given update changes the IOAHCIBlockStoragefile. If not, you won't have to do it again. If it does, you will. Sofar, in the last couple of OS X updates, the pattern has been like...60% of the time you have to redo the patch.[/FONT]
