Angelbird/ssd Wrk Waves Silver Native For Mac
The potential trouble with TRIM and kext signing is the only reason I deleted Yosemite and went with Mavericks. There were some other minor OS issues, but nothing as bas as the TRIM issue for me. I stuck with Snow Leopard untill a week ago and I'm fine to stay with 10.9 just as long or until there is no more TRIM issue. Anyway, 10.9 seems to run smoother than 10.10 for me on my 2011 Mac mini server. This reminds me of when Apple prevented iMovie and iDVD from working with any burner other than an Apple one.

Even if you plan to continue using Trim Enabler on Yosemite, it's best to bookmark that page on your iphone and become familiar with it because it is likely one day you will need it. Here is my understanding of TRIM vs. Controller-level garbage collect - albiet it may be wrong, so if someone else is an expert please correct me. The sort of garbage collect that is built into the SSDs looks for data which has been marked as deleted in the file system, and erases it. However, since there is nothing actively pointing it to that data, it pretty much just runs from the top to the bottom over and over again while the SSD is idle.
This means that sometimes deleted data does not get noticed and taken care of for some time. TRIM fixes this issue by adding an active signal that the OS sends to the SSD alerting it to where the deleted data is, thus it is taken care of more promptly.

Click to expand.I wouldn't say only, but essentially that is correct. Trim Enabler works by modifying an Apple kext which holds a list of Trim-compatible drivers. You can still use Trim Enabler, and it will automatically disable that kext security for you if you so wish.
That isn't the problem, as far as I understand. The problem is, unlike other OS X settings which are stored in on the hard drive, this security setting is stored in the PRAM, which can be reset either deliberately when troubleshooting another issue or can be reset unexpectedly for a number of other reasons. If PRAM is reset, then the security setting is re-enabled, and it prevents OS X from loading the modified kext, and the user will be presented with an unbootable system displaying the do not enter sign.
This can be fixed by either unmodifying the kext or re-disabling the security feature. However, at this point, it's not easily done using the automatic Trim Enabler UI, it has to be done in the terminal using recovery mode. Also, this article summarizes the Anglebird PR pretty much: For now I have a 120GB Samsung 840 Pro in my Mini, but I may upgrade to one of these once prices drop a bit more.
