Mac OS X 10.6.8 Brings TRIM Support for Apple SSDs, Graphics Improvements

What if they are? If you want a file, don't delete it.
No offense, but why would you want to recover a deleted file? I mean you already have the option to recover it from the trash... If you delete it from the trash then you probably don't need it at all (or you should have thought better)

No offense, but you're putting a lot of words into his mouth. He just asked if it made deleted files unrecoverable more quickly. For all we know, he might consider that a GOOD thing. I know I do. :)
 
Related to the graphics updates I'm guessing, I have noticed that occasionally upon boot my screen backlight turns off and back on (MacBookPro6,2). It doesn't happen all the time and it's hard to reproduce, but it didn't happen on 10.6.7 or below and a PRAM/SMC reset haven't changed the situation at all.

The following videos show the issue:
Issue occurring where the screen cuts out during boot process: http://www.youtube.com/watch?v=8wNsqpENnN8
Regular "seamless" boot: http://www.youtube.com/watch?v=Bd4Q_OLSrvE

Ive also noticed that the keyboard backlight takes a second or two to kick back in now after the computer has been sitting idle whereas before it would come on instantly when you moved the cursor or pressed a key. This particular issue also seems to occur on the new MacBook Pros (2011 models, even with 10.6.7 on those) so I'm guessing it's something that Apple has changed starting with the special builds for the Feb 2011 MBPs.

Anyone else seeing these behaviors?
 
Not those. But I am not able to put my system to sleep and my audio out to my mixer is broken.

I'm not impressed with this update.

Don't care for TRIM support unless its for Intel, OCZ and other superior third party SSD drives. Apple's toshiba rebranded drives are a joke.

What is their excuse for not supporting other drives?

With any luck, non Apple drives will be supported on the release version.

Sometimes, you delete the file so others can't get it. When I am traveling, I run a very clean build of my computer that does not have files I don't want others to see (Do you know what the cleaning lady does with your computer when you are down at the bar?). That said, the ability to delete files so they can not be retrieved is a good thing.

Question for the board, does anyone know how Trim works with PGP Whole Disk Encryption? How about the Lion native HD encryption? I would assume every sector is marked used all the time, so PGP+SSD=bad.
 
Someone who was incredibly annoying asked about TRIM support with his new iMac (while he ordered SSD from Apple, he still find it hard to believe that Apple has enabled TRIM for his new super expensive machine) ... this article is precisely for him, and nailed it good.

I hope this just opened his eyes about TRIM SUPPORT IN iMac, and BE DONE WITH IT.. and GET OUTTA HERE :D

Oh, well .. :rolleyes:
 
I've noticed significant increases in graphics performance in 10.6.8, especially when using Aperture (MacBook Pro 15", 2.2 i7, 4 gb ram, early 2011 model). Previously under 10.6.7, Aperture would take 2-3 seconds to load each photo as you scrolled through them in full-screen. Now the pictures instantly as you scroll through. I was very disappointed with the speed of my Mac when I bought it and upgraded to 10.6.7, especially because I was updating to take advantage of the supposed graphics capabilities of the new macbook pros with dual graphics cards, so this is a good update.
 
No TRIM Here

unfortunately :confused: no TRIM here ... i have a MBA2,1 the second issue of MBA with the 128Gb SSD and even with 10.6.8 TRIM is not enabled ... any ideas if the update applied to ALL the SSDs Apple used in ALL their computers? Or if some are still excluded?

Good drives- like Sandforce or Intel based SSDs-- do not need TRIM. TRIM is only useful for dumb flash drives, and you shouldn't use them anyway, because, even with TRIM their useful life is likely to be only a couple years.

That is not true whatsoever.

In my case I use my MBP 2.4 CTD and MP 3.2 quite a bit so I notice when they feel "different". Since the update apps like iPhoto, iTunes and Safari seem to open and operate faster.

Whether it's because of program execution or screen drawing I don't know. But both machines feel faster in a very general sense.

i'm glad that you're seeing improvements, but i hardly notice a difference, if anything it feels slower in some points, mainly pulling it out of sleep.

Apple has just decided not to enable it on other drives for political reasons. There's no technical reason. Windows supports TRIM generally, so could OS X.

Windows has to support Trim generally, since otherwise it would be virtually useless in light of Windows' licensing to multiple vendors. Since Apple isn't licensing OS X to any other vendors, they don't have to support Trim generally. It's not "political," it's practical.

Huh?

TRIM is a standard but optional ATA feature.

When you buy an SSD, it will report to the OS whether it supports TRIM as part of the device identification protocol.

Apple are being d#ckheads in ignoring the device's support for TRIM if it isn't one of the Apple supplied SSDs.

Windows is simply accepting the device's claim that it supports TRIM, and if so sending the TRIM commands to the device. Licensing has nothing to do with it - Windows is simply accepting the device's claim that it supports TRIM.
 
I bought a used 256GB Apple branded Toshiba (TS256B) off of ebay for my mid 2009 macbook pro. Under 10.6.7, there was a "no" next to TRIM. Under 10.6.8, it says "yes" next to TRIM.

Perhaps your SSD does not support TRIM. If an SSD does not support TRIM an OS update is not going to change that.
 
Very odd, because while I get a negligible graphics increase from 10.6.8, I get a significant CPU performance decrease moving from 10.6.6 & 7 to 8. After doing the maths, my computer is now 6% slower due to this update. Not very happy.

This is according to Novabench, and I don't know how reputable the tests are.

10.6.7 (says 10.6.6 - but it's a problem with the save file)
10.6.8 (will say 10.6.6 when I save it - LOL)​

MBA 3.2 = TRIM
MacMini with OCZ Vertex 2 = No TRIM

just as they said it would be :rolleyes:

I am also experiencing these behaviours, the integrated intel graphics does seem snappier though.

Running a 2.4GHz i5 15" 2010 MBP.
