hi i got an imac , it come with an hard disk i wanted to change it with a ssd i bought an crucial ssd the operation system is sierra last version , and trim it's disabled what should i do ? keep disabled or enabled? thanks
This might better be answered on a Mac forum but I find it odd TRIM is disabled. I would think it would automatically be enabled when the OS detected the SSD. But I really have no experience with that OS so either wait for someone with that experience to join this thread, or visit a Mac forum. If you get your answer elsewhere, please post an update back here so we can learn something too.
I don't know if this is the link they sent mantra, but it does explain it. http://forums.crucial.com/t5/tkb/articleprintpage/tkb-id/ssd@tkb/article-id/84
Interesting. What I have always done with my PC was to boot up and not login. I will let PC remain with login screen for a couple of hours. This has always seemed to improve performance. I will do this once every couple of weeks. Anyone else seeing this?
hi i sent an email and i copy and paste the answer hi but other brands does include this feature i don't think it's normal , 2 hours are too much , what ssd do you have?
But it doesn't explain why TRIM was disabled in the first place by the iMac. That article clearly states (my bold added), That suggests to me TRIM is preferred but, "if for any reason" TRIM is unavailable, "Active Garbage Collection" will step in (when the drive is idle). So the question remains, why is TRIM disabled on that iMac? And should it be enabled?
hi i have sent an email to crucial and i have asked i change ssd on my imac with a crucial should i enable or not trim ? they reply with an email ,i pasted here
Again, that does not explain why TRIM was disabled in the first place. That email only says that Crucial has you covered in the event TRIM is "for any reason" disabled. So, do you absolutely need to enable TRIM? No. But if me, I would still want to know why your OS disabled TRIM in the first place. It would seem, for some reason, your OS did not enable it. Why? I don't know. Again, that might be something best asked in a Mac forum but according to this C|NET article, because your SSD was factory installed, it should have been enabled.

hi interesting guide , really i guess it's apple (even a burner should be approvated by apple) , i don't know what brand and model of ssd they use maybe with the same brand and same model (for example of sierra) , osx sierra enable it by default
hi Rainwalker may i know which ssd brand do you use? i use mostly samsung e crucial thanks for the links
This article is from 2015, but I think it still addresses the issue... EDIT: Sorry, I just noticed Bill_Bright posted a link to the same article above. I was scanning through the commentary and did not see it before I replied. My apologies. But it does seem most apropos, and the answer as to why it's not on by default appears to be that Apple does not wish to bear the responsibility for the compatibility of untested 3rd party hardware.
