10.9.4 and TRIM

I have 2 Macs with Intel SSDs where I enable TRIM using the comprehensive and simple guide written by Grant Pannell.

Unfortunately, with the debut of 10.9.4, this guide has stopped working.

I've not tried other methods (Cindori's TRIM Enabler etc), but I notice on their forums they're suffering from the same issue.

This is mostly to let people know that it's an issue, and if you require TRIM, an advisory to stick with 10.9.3 for now.

Just install 10.9.4 and enable Trim with Cindori's Trim Enabler. It works just fine as always.
 
I'm having the same issue as the OP on my 2011 MBP. I tried via the perl method as well as Chameleon SSD Optimizer, neither are working for me.

Did you read the post above yours? Neither the perl method or Chameleon SSD Optimizer work now, but Cindori's Trim Enabler does (latest version).

It's working on my SSD now:cool:, had to use Trim Enabler again after the 9.4 update.
 
Why is TRIM such a problem on 10.9 and 10.10? SSD's are very popular and very much the future. So why is there poor support for such a necessary SSD feature such as TRIM? Surely it should be enabled by default as there's so good reason not to have it enabled?

The only reason why Trim Enabler still works is that it just copies a modified IOAHCIBlockStorage file that originally dates back to Snow Leopard (10.6). This way, you introduce some bugs. I'd rather stick without TRIM than to use Trim Enabler. Just my 2 cents. :confused:

No go for me

That is bad information. This was true of Trim Enabler V1, but since V2 Trim Enabler modifies the existing kext just like the Terminal command does. It does not use the old Snow Leopard kext.
 
:D This time with update 10.9.4 Trim enabler told me trim wasn't enabled, did it reenabled and trim is working !!!! Super Thks much appreciated trim works easily !!!! :D

if you prefer to patch it yourself through the terminal, here's the updated version.

just remember to scroll all the way to the end when copying the line, since it extends beyond the confines of the window.

Thanks for this, will try it when I get home :)

I'm sure TRIM enabler would work too, I just prefer to see the exact commands needed to make it work :)

Because Apple wants to sell OVERPRICED SSD's for native trim support, with just a tiny 'tweak' in a Samsung SSD like the one that came with my 2012 MP 5.1! :rolleyes:

Model and manufacturer + 500Gb or 512GB ?

Tried to Google for the manufacturer and model of this SSD, what codes are best for this search? I'm even more curious why it's listed as 500GB in stead of 512GB that is printed on the label and is engraved on the original Apple SSD alu enclosure to use one of the sleds in the HDD/SSD bay. Popped it into my USB 2.0 disk duplicator for a quick view

Perhaps a read-out error?

Your drive is a 512GB Samsung PM830.

This is false information.
Trim Enabler 1.0 (released back in 2011) used this as a method. It also had a label stating "Only for use on Snow Leopard".

Ever since Trim Enabler 2.0 (released back in 2012), Trim Enabler unlocks the kernel extension directly, leaving your OS otherwise unaltered.

Trim Enabler has made quite a journey since then. Here are screenshots of version 1, 2 and 3 respectively to put things in perspective.
