It’s called App Trim Enabler found at: Note 3 (: Easy to use and you need to reboot afterwards. I found in Internet an application that does the trick though even in 10.7.5. Well, that was rather expected, but the unexpected thing was that the above method with the terminal commands this time didn’t work. I just updated my OS X from 10.7.4 to 10.7.5, especially because of WiFi instability, and found my TRIM support going from ‘Yes’ to ‘No’. I’m very thankful to the people who have worked to discover this modification and made it available to us. I have installed a 512 GB Samsung Series 830 on my MAC Book Pro i7, followed these instructions and all worked without a glitch.

Therefore all non-Apple SSDs don’t get the feature. Well here comes the bad news for MAC Lion owners … and the the good ones afterwards □ The BAD NEWS:Īpple has restricted the TRIM function only to the Apple identified SSDs. This saves a lot of writing time, therefore keeps the high writing speed of SSDs up to their maximum throughout the life of the SSD. The TRIM function regularly deletes the unused space on SSDs while the CPU/IOs are not too busy. This is where the TRIM function of a system comes in play. This means with time the writing speed of SSDs starts to slow down drastically. In SSDs the technology demands that the old data be first erased before new data will be written, which slows down the writing time. With rotating hard disks, the new data is simply written in the available space without having to erase the old one before. That is where SSDs and rotating hard disks differ. When it is used again the new data will overwrite the old one. ![]() So the space that is been made available again will soon or later be used again as we would expect. That is why sensitive information should always be overwritten by something instead of simply erased… but that is another subject. In normal hard disks when a file or directory is been erased, in fact the space used by the file or directory is simply put back on the unused space list.
