OS X :: SSD TRIM Support In Snow Leopard?
Feb 7, 2010
i'm planning to buy a macbook as soon as they appear with Core i5 processors, and since i want teh fastest most reliable experience possible, im also getting an SSD.After using a Solid State Disk with my windows xp machine, i've realized that without TRIM, write performance degrades considerably.This leads me to ask two questions, and any help is greatly appreciated:1. Will this SSD work if i format it as a mac drive?256GB Samsung SSD - its gotten good reviews off amazon, but i wana ask the experts (macrumors community

I purchased an Intel 34nm 160GB SSD 12 months ago to install in my MBP 13". It has been an excellent drive, however, started to significantly slow down over the last few months. The only way I was able to recover to original speeds was by formatting the entire drive as a windows drive and running the Intel SSD Toolbox app in Win 7 (manual trim command).Finally I reinstalled OSX and voila drive was as fast as when I initially purchased it.Either Intel needs to release a OSX compatible toolbox app or Apple needs to build the functionality into OSX.I know this has been a topic before but thought I'd share my experience.

How long/soon do you guys think we have to wait till OS X gets TRIM support? Do you think we will get it in 10.6.5 or do you think we will have to wait till 10.7?

What is the significance of the Mac OS X 10.6 not having trim support for SSD drives? I was looking at Crucial's C300 drives, but then I read about trim support being really important.

I've spent the best part of the day researching SSD drives, I'm wanting to pop one in my MBP.I've been looking at the OCZ Vertex and also the Intel X-25M Gen 2.I've set my heart on getting the OCZ but after spending a good hour on their forums, it seems that (like all other drives) there isn't a 'wiper' tool available for OSX.Should this affect my decision? No-one knows if Snow Leopard will support TRIM and I don't want to left with a drive that has lost most of it's umph after a few weeks.I don't claim to know all the details of TRIM (I'm a mere-mortal wanting faster performance), so please feel free to put my mind at ease

First post so I apologize for any rules I may be breaking. A lot of discussion on this forum has centered around SSD's and their use. From what I have gathered, the price is quite high, but the speed is impressive. I am going to university next year and am looking for a new laptop. I have used Windows all my life and don't have anything that really requires OSX (graphics applications, etc). However, I like the design of the MBP and want something high quality that will last me 4 years. The SSD's are looking pretty appealing for the sheer speed, but OSX doesn't support TRIM, which could affect future speeds.

Used to run Flip4Mac Pro Version 2.2.3.7 with Quicktime 7 Pro on Leopard.Upgraded to Snow Leopard and got the 'Quicktime must be installed on this machine...' messages. OK, fair enough. Known issue.
Installed the Snow Leopard compatible 2.3.0.11-BETA with Pro licence but now have lost the ability to trim movies once they are opened in the Quicktime X window. However, if I navigate and open with Quicktime 7 Pro I can trim them.
Can anyone explain I should expect to happening and/or if this a bug or what?

It looks like OS X supports TRIM, but still says that my SSD doesn't support it. How stupid is that?

Let's hope this happens for Mac Pro's as well.Here's the story on AppleInsider...Apple may be laying the foundation for TRIM support in future Macs, a technology that should allow their solid state flash drives to maintain optimal performance throughout the life span of the systems.The Mac maker's most recent 13-inch MacBook Pros display an option for TRIM support in their system profilers on SSD-equipped models, one which isn't present in either the second-generation unibody 15-inch MacBook Pros or the latest refresh sporting Intel's Core i5 and Core i7 processors.

Could someone check in their System Profiler -> Serial-ATATRIM would be really useful during the lifetime of the flash drive.

Whenever the MBP refresh happens I intend to upgrade the stock HDD to a 7200rpm 500GB HDD or, less likely, to an SSD. An SSD had been my first option until I learned about SSD performance degradation and the lack of TRIM support in OSX. I was ready to stomach the massive SSD price premium, but the lack of TRIM would most likely rule it out completely for me. And I recall reading something about the MBP hardware connection (perhaps the the SATA connector) having a slight bottleneck compared to SSD-equipped Windows machines; so some of the top of the line SSDs won't be able to max out their transfer rates on OSX. (This is the best, not so informative, link I can find now referring to that impaired performance: http://macperformanceguide.com/Revie...tml#Single_MBP) With these performance issues, I've become perplexed why SSDs are popular amongst some Apple users

The new Nvidia Chipsets used in the current crop of Macbooks can Use up to 8Gb Of Ram however apple claim to only support 4GB. People have put 8Gb into the new macbook Pro only to find the OS is unstable and unable to address the full 8Gb, 6Gb however works ok. I am guessing the limitation is the OS. Support for 32-bit apps and parts of the OS that are there for older hardware. Can any of you wiz kids shed some light on 10.6 for me will it support the full 8Gb of RAM?

I routinely transfer files bigger than 4GB between Windows and OSX. Right now I use ntfs-3g and macfuse. It seems to work, but every now and then I get file transfer errors, like error -36. The jump drives are fine, and the files are OK since I can transfer them to the PCs without a problem. With the "hack" that enables native NTFS R/W for Snow Leopard, I notice people have to enter the UUID of each volume for it to automount. Isn't there a way to set it up so one can just pop a jump drive in and have it automount? I'm dealing with DV files, and each machie is on a different network - different site so I'm pretty much stuck using removable drives.

Documentation included with copies of Mac OS X 10.6 Snow Leopard distributed during Apple's developer conference this week confirm that the next-generation operating system does not presently support Macs with PowerPC processors. LogicielMac.com has published a screen capture of the PDF-based requirements document included on the Snow Leopard disc that provides a rundown of the system's requirements.
The documentation states that in order to install Snow Leopard, developers must have a Mac computer with "an Intel processor" and at least 512MB of RAM, though additional memory is recommended for development purposes. The findings confirm an AppleInsider report from last September, which cited people familiar with the ongoing development of Leopard as saying that Mac OS X 10.6 would in all likelihood exclude support for PowerPC processors. According to the Snow Leopard documentation, the new system will also require an Apple-supplied video card, 9GB of hard disk space, and either an internal, external or shared DVD drive.

Right now it says 4 gigs is max, and there are reports that it actually supports 6 gigs. But I know that with a 64 bit OS, ram additions are unlimited. So will this 4/6GB limit be lifted once I install Snow Leopard?

I recently installed Snow Leopard. It works faster than before and it gave me 8GB of space back. But, after looking through Applications in system profiler, I found out iTunes is not 64-bit unlike Safari and other native applications that have been re-written to 64-bit. I remember Apple said iTunes is also re-written. I must download a new version or it's included in an update (I'm waiting the 10.6.2 update to download at the moment)?
