#YOSEMITE TRIM ENABLER MAC#

In cases where you have such a modified extension installed, your Mac wonвЂ™t be able to boot from the drive. If Yosemite encounters such a modified kext file, it wonвЂ™t run. The workarounds that allow TRIM to function with third-party SSDs require that kext files are modified. With Yosemite, kernel extension ( kext) files must be вЂњsignedвЂќ (or approved) by Apple for security reasons. This worked perfectly well with Mavericks. Instead, youвЂ™d do some Terminal work or use a third-party tool such as Cindori SoftwareвЂ™s Trim Enabler to make TRIM work with your drive.

However, if youвЂ™ve installed a third-party SSD, that drive doesnвЂ™t use TRIM because AppleвЂ™s TRIM technology is not built to support it. If you purchase a Mac with an SSD or Fusion drive built in, the TRIM technology is working away in the background to keep your drive running at its peak. In sum, the two technologies speed up the driveвЂ™s performance so that itвЂ™s not performing a lot of needless move and erase actions. Invalid data is erased when the drive is otherwise idle. TRIM works at the operating system level and ensures that only the good data is moved. The controllers within SSDs have a technology called вЂњgarbage collectionвЂќ that moves the data within pages-both the good and invalid data-to new blocks and then erases the old ones. This takes time and slows down the driveвЂ™s performance. So if you have a block where half the data is good and half invalid, you have to move the good data to another location before you can erase the block. The difficulty is that the drive canвЂ™t erase individual pages.
