    I installed the Samsung Evo 860 SSD in 2011 "15 Macbook Pro El Capitan this morning and it works wonders! The laptop is on speed steroids. So, I checked the system report and it says no TRIM Support. The TRIM Support was enabled on the original hard drive that it came with the laptop. Should I enable it or should I wait and try to update the OS to Sierra and see if it works? Or does it even need to be enabled at all for SSD?

    Yes to TRIM. If you ever upgrade to High Sierra, I also recommend skipping the conversion to APFS.

    So, I enabled TRIM Support. Do I have to do anything else with the SSD before updating it to High Sierra?

    I was under the impression that if you have pure flash storage and upgrade to High Sierra that you will have no choice in the format. APFS will be automatically installed. Do you know of a way to prevent that?

    Why is it better to skip the conversion to APFS?

    APFS is still a bit of an unknown file system, especially for how it is designed to handle non-Apple SSDs. Existing disk utilities seem to handle the older file system better, so you don’t have as many management issues like if you want to partition or use Bootcamp. I even found HFS+ to be a little faster with my SSD as well back when I had a cMP.

    I installed an 860 Evo in a end 2009 macbook white A1342 running High Sierra.
    First formatted in HFS+ but that was very slow. Reformatted in APFS and it was much faster.

    I use no trim because:
    a: apparently is isn't necessary when using APFS.
    b. I couldn't find guarantee it would work okay, not even from the Samsung helpdesk / phone line. Som even say it might damage the drive.

    Did not noticed speed-drop so far, except from the SATA2 connection which doesn't match up with SATA3 speeds of the drive. But that's normal. Also, the latest OS X 10.13.5 (01June2018) seems to have stabilized the system a bit more and disabled my TRIM-enabler program. Perhaps for a reason.

    So, in my case happy run APFS and no trim

    There is no need for third-party trim enablers starting with 10.6.8. Trim can be enabled using terminal commands.

    I'm not sure if enabling trim on a third-party SSD makes a different but it is enabled by default for Apple SSDs. I haven't encountered any issues with APFS and trim.

    I understand it isn't necessary at all with APFS? It seems to work fine so far. But that's just for a few days now. I can backup through time-machine as well in APFS, something that wasn't possible before apparently. Which makes me guess APFS issues have been worked out with the latest update.

    Not sure if trim is or isn't needed with apfs but trim is enabled on my early 2015 air and late 2013 13" Pro, both of which are running a stock apple SSDs with high Sierra.

    I would enable TRIM. The only reason it's not enabled for you now is because it's a third-party SSD, so Apple doesn't enable TRIM by default. If you have an Apple-issued SSD, TRIM will be enabled, regardless of the file system. My 2017 iMac with Apple SSD, for example, has TRIM enabled with APFS on HS through no work of my own.
