SSDs and Mountain Lion

Crucial M4 256GB in a Early 2011 15" MBP working fine!

 

[wildcat1451]

Just thought I'd let everyone know I'm using a 128gb Vertex 4 and am having issues. Installs and boots fine, however mail app crashes and will not re-open, same with iTunes, syystem preferences will also not load after this has happened. Only solution is a restart. Also cannot connect to internet. It appears that the hard drive freezes up and that Mountain Lion says there is no space available, as i am unable to download or do anything that requires any free space. Done 3 clean installs and is a brand new drive. Not sure if anyone has the same problems? Trying to downgrade back to lion now but thanks to Apple pulling Lion from the app store i have to do it another way. Very frustrating.

 

[Zarkizon]

can anyone confirm or deny that the Crucial m4 256 gb ssd works with ML?

It works perfectly with OS X Mountain Lion.

 

[Stooby Mcdoobie]

I'm also using the m4 256 GB SSD and haven't had any problems with it.

Samsung 830 SSD

I'm running a Samsung 830 series SSD on a late 2011 17" MBP with Mountain Lion on it. So far, no problems encountered that is related to the SSD itself. I've only had the finder lock freeze up one me once and I've had it running since it was launched.

Would the Finder locking up be attributed to the SSD or the OS?

im intending to buy the samsung 830, from what i hear, apple is using this vendor for their ssd, so i hope it works fine! :|

I can confirm that the Samsung 830 SSD works flawlessly on my late 2011 MBP and 2009 Core 2 Duo 13'' MBP, both running Mountain Lion. You will have enable TRIM manually using the TRIM Enabler app, which is free.

 

[SlCKB0Y]

but my guess is that with mountain lion apple are trying to make it harder to install their new os with non-apple hardware.

So this thread is just a warning that if you intend to upgrade to mountain lion in a few days time, there is a good chance that if you are using non-apple ssds, you may experience some problems.

You're actually suggesting Apple are doing this on purpose?

ML works fine on my Crucial m4 and two full pages of replies with only one other person having a problem with another OCZ drive says you're being alarmist.

hi!

thanks, mine is due to arrive this week, as i went ahead and purchased it, the 256gb model, for £155 (it had been floating between £180-200 so im quite pleased) i also got the 16gb ram.

do you know where i can get the trim enabler app? im also quite confused about trim, some people here say its bad for OS X or un needed, and others like yourself suggest trim should be enabled :S

That's a good price. I too was watching intently as it hovered around £180, then one day, I got the 256GB on Amazon for £144, which isn't even the lowest I've seen it... £139!!!

Here's a link to TRIM enabler.

thanks, do you know anything about this??

"As I posted there is a massive thread about this app over on Macrumors. Use the search. Some had issues with this app, others didn't. If TRIM does not come with your device, I would think twice about enabling a hack that not supported by 10.7."

I have been using the Single User Mode trick with 10.8 and my 256GB OCZ Octane.

Sometimes it takes a couple tries, but once I am in, no problems at all.

 

[blueroom]

My OCZ Octane S2 (4.14) will not boot ML and won't until newer firmware is available. Had to resort back to Lion.

Unfortunately I let TM complete after ML, the downgrade to Lion wasn't smooth, Mail is still broken.

 

[al404]

i have a samsung 830 ssd i upgrade to ml without issue

but now when i boot i have the spinning wheel and i have to force shut down holding power button, the second time it boots correctly

how can i solve?
i have bootcamp partition

 

[nikhsub1]

Problem is PEBKAC more than SSD's... no issues here.

 

[blikecray]

My issue was solved (OCZ Vertex Plus) I had 3.02 firmware, used a windows machine to upgrade to 3.55 firmware then used OCZ tools to do a secure erase (not the same as using disk utility, this is much better) and installed a fresh copy of ML without any of my previous issues (external hard drives not showing up, random reboots, etc.). Whew, finally!

Trim support Intel 320 SSD in ML

Intel 320 160GB works like a charm with OS X 10.8 Mountain Lion!

Peace

Hi,
Have you got trim support working in ML with your intel 320 series ssd?

I keep getting the following error with terminal commands and cannot get trim enabler to work.

Kernel file /mach_kernel does not contain requested arch: i386

Cheers,
Simon

 

[SlCKB0Y]

Kernel file /mach_kernel does not contain requested arch: i386

That's a warning, not an error. I had the same thing but trim was enabled.

Did you actually check if trim is showing up as enabled now?

 

[peejack]

I have a Crucial M4 (256) that is having the same problem. To anyone with a Crucial M4 that is working, did any of you upgrade from Lion or Snow Leopard? Also, did any of you have the trim enabler installed?

No problems here at all m4 256 with mountain lion.

 

[Sital]

So this thread is just a warning that if you intend to upgrade to mountain lion in a few days time, there is a good chance that if you are using non-apple ssds, you may experience some problems.

No problems with Plextor M3 Pro. Working great.

 

[Ifti]

Another thumbs up for the Samsung 830 - ML running fine with TRIM enabled using TRIM Enabler.

 

[simon999]

That's a warning, not an error. I had the same thing but trim was enabled.

Yeah, checked after reboot and in system information says it isn't enabled. I checked the file that the terminal command changes and it has correctly changed "Apple" to zeros.

I'm a bit baffled as it was working fine in Lion but just won't now work in ML.

Anyone experienced similar?

Cheers,
Si
P.S. Also tried trim enabler but says "The patch is active but trim is not working"

----------

Could some nice person post a link to their correctly amended file:

/System/Library/Extensions/IOAHCIFamily.kext/Contents/PlugIns/IOAHCIBlockStorage.kext/Contents/MacOS/IOAHCIBlockStorage

so I can try a swap and see if mine's corrupted.

cheers guys and girls!

 

[shortcut3d]

No problem with ML on 240GB OWC Mercury Extreme Pro 3G and 480GB OWC Mercury Extreme Pro 6G.

Instead of changing "APPLE" to zeros, I changed it to "INTEL".

Works great with my Intel 120 GB 320 series SSD in ML.

Also, instead of doing those 2 kextcache commands, I did "sudo touch /System/Library/Extensions/".

From the kextcache manual
“Installers and administrators should not use this program to update system kext caches. Instead they should run “touch” on the /System/Library/Extensions/ directory of the installation target volume after they have finished, which causes the system to update all necessary kext caches.”

Hence I think you could think about changing the guide to:
sudo touch /System/Library/Extensions/

Just an idea

Here's my patched IOAHCIBlockStorage file for OS X 10.8 (Build 12A269) and Intel SSDs (the Model must start with "INTEL SSD" or else trim won't be enabled, but no harm otherwise).

http://minus.com/lbg4bN7aIEJMIA

Put it in place (rename to get rid of .patched, you might want to fix its file permissions also) and do:

sudo touch /System/Library/Extensions/

As widely reported elsewhere, SandForce SSDs do NOT require TRIM!

 

[duhmask]

the latest version of TRIM Enabler works on Mountain Lion already, one could just install it instead of going through the process manually (?)
