Lukáš Čambala On Tuesday, when the new operating system OS X Yosemite arrived in version 10.10.4, it also added a new essential functionality – TRIM support for third-party SSDs, without any additional intervention in the system. This is a significant step forward, as Apple has so far only supported TRIM on "original" drives that came directly with the Mac.
To activate, you must enter the following command in the Terminal: sudo trimforce enable. Before the reboot itself is performed with the process of turning on the service, a message pops up about possible incompatibility with some types of SSD.
TRIM is a command that the operating system sends to the disk to notify it of data that has not been used for a long time. TRIM is used to speed up data writing and also to wear data cells evenly.
For the very first time, Apple's TRIM support appeared with the arrival of OS X Lion, now third-party SSDs finally support this command.
oh guys from the GDR, it doesn't go to write to the terminal... it doesn't even go to copy to the terminal
Hallelujah. Finally. I have yet to find certified SSD drives and I will be satisfied...
Yes it works OK with Intel 530
So it can be turned on. Nobody knows if it "works OK".
We'll see what that does... I've used Trim Enabler so far - no problem. They made me happy with 10.10.3, finally my MBP started to start briskly like I'm used to. After installing 10.10.4, the startup speed remained, shutdown became faster. Great! Then I found out that the installation turned off the Trim Enabler and the information about the computer (the more detailed one) was completely scattered - the font is written in columns (1 letter on 1 line). I turned on TE, restarted and ... again in (_!_) - slow as at the beginning of Yosemite. A few reboots, still the same. Grrr. Golden Snow Leopard!!! Last attempt with this bazmek, hopefully the system TRIM will help him. I envy those who use apple for a short time - they don't remember the days when it was TRULY the best system on the best computer…
… tried, turned off Trim Enabler, rebooted, significant acceleration. I started Trim in the Terminal according to the instructions in the article, it was recognized without a problem, restarted and the speed is there again. In System info (still scattered), the computer reports that Trim support is OK. Another reboot… Hope dies last and now its time has come. So the new update is UNUSABLE on MBP early 2011 (i7, 4-core, 16 GB RAM)!!! So I can actually choose: a fast computer during which I hunt for a not exactly cheap SSD, or save the disk and start smoking even more than now - I have a lot of time for that... Thanks Apple for the freedom of choice!
And how, please, do you "hunt" the disk without using TRIM? Every SSD without a difference has its own garbage collection algorithms, which basically do the same thing as TRIM, but at the disk firmware level, regardless of the OS. TRIM is then only a function that enables this behavior to be improved at the OS level for supported SSDs. TRIM enabler is a 3rd-party utility that turns on a critical function (critical because it can affect data integrity) and if I love my data, I would avoid it. Ad) your experiments with turning TRIM off and on - any impact on speed definitely cannot be manifested immediately. If something like that happens, the problem is somewhere else entirely.
We are testing from the first beta of 10.11 and we will see how the stress tests will look like.
Hello,
I also used the TRIM enabler, but after turning it on there was no problem (miniMAC). It's true that we didn't measure the speed, but it boots for me within 10 seconds.
