TRIM has numerous problems, not the least of which being drives and/or filesystems which do not implement it properly. SSD performance and firmware has undergone radical improvements every year and people have come to the mistaken belief that enabling TRIM is responsible for most of the performance and wear leveling improvements. It isn't really true that SSD performance goes down by a whole lot if TRIM is not enabled. I'd be hard pressed to come up with more of a manufactured controversy. Trim Enabler even has a GUI to do it for you. I haven't done so on the 840 EVO I swapped into my MBP because I've judged that it's not worth the tradeoff for me, but it's an option. Even today, you can still turn TRIM on for yourself as you described, at the price of reverting to pre-Yosemite security. I can imagine perfectly non-nefarious reasons why Apple would disable TRIM by default and only enable it for drives that have been explicitly tested for compatibility. They call Apple support to scream at them for writing a terrible OS that loses their data, and Apple loses money and reputation. SandForce, anyone? Someone goes to Best Buy and comes home with a new SSD, pops it into their MBP, uses it for a month, and the thing asplodes and eats their data. SSDs have a history of notoriously horrible firmware. For example, my 2011 MBP has normal Phillips screws on the bottom, and it takes me about two minutes to have the back panel off and the RAM and HDD snap right out. This was considered a normal thing to do and didn't void warranties. Older MacBook Pros came with instructions for replacing the RAM and hard drive. Just let us enable trim on non-Apple drives natively and there's no problem!Īpple, for whatever dumb reason, has _never_ enabled Trim on non-Apple branded SSDs. Tl dr - a rather hysterical take on an issue that DOES display some Apple stupidity. Trim Enabler is just an unfortunate casualty of kext signing (which itself is probably not a bad thing!). I doubt trim even crossed anybody's minds during the decision-making process. There is absolutely no reason to believe that the decision to make Yosemite require signed kexts has anything to do with the status of trim on non-Apple SSDs. You CAN override this behavior, but there are potential issues ( see the Trim Enabler site for more information ).
TRIM ENABLER 840 PRO SOFTWARE
Since non-signed kexts are blocked, software like Trim Enabler cannot load. The difference in Yosemite is, as the summary says, non-signed Kernel extensions cannot be loaded by default. I've been running multiple Macs since OS 10.6 with multiple brands of SSDs (OCZ, Samsung, Intel, etc) with absolutely no issues and no signs of performance degradation. One toggle switch, one reboot, piece of cake.
TRIM ENABLER 840 PRO INSTALL
Any user who was able to install their own SSD could also download the handy TRIM Enabler software that forced Trim on for non-Apple SSDs. I do not know of any HDD manufacturers that ever provided any kernel extensions that would enable Trim for their drives, so effectively, third-party SSDs have never had any official trim support on OS X.īefore Yosemite this has never been an issue. However, with OS X, if a third-party SSD is detected, the OS will detect that a non-approved SSD is in use, and Yosemite will refuse to load the appropriate TRIM-enabled driver.Īpple, for whatever dumb reason, has _never_ enabled Trim on non-Apple branded SSDs.
TRIM ENABLER 840 PRO DRIVER
It's conceptually similar to the device driver checks that Windows performs at boot.
TRIM ENABLER 840 PRO DRIVERS
KEXT signing means that at boot, the OS checks to ensure that all drivers are approved and enabled by Apple. What Apple did with OS X 10.10 is introduce KEXT (Kernel EXTension) driver signing. Without it, an SSD's real world performance will steadily degrade over time. Being able to perform TRIM and clean the SSD when it's sitting idle is vital to keeping the drive at maximum performance. We say "effectively" because while third-party SSDs will still work, they'll no longer perform the TRIM garbage collection command. Now, with OS X 10.10 Yosemite, the company has taken another step down the path towards total vendor lock-in and effectively disabled support for third-party SSDs. Over the last few years, Apple has introduced features and adopted standards that made using third-party hardware progressively more difficult.
TRIM ENABLER 840 PRO UPGRADE
MojoKid (1002251) writes One of the disadvantages to buying an Apple system is that it generally means less upgrade flexibility than a system from a traditional PC OEM.
