    If you do have "Trim" enabled on third party SSD's. it is highly recommended to disable it before starting the upgrade to avoid any problems.
    It can then be re-enabled after the upgrade has completed.

    Because?

    As every OS X update, there will be no PRAM Reset.

    You should recommend this if someone will install a firmware upgrade or make a hardware maintenance, but not if you are installing an OS X update.

    I think that is good advice, Trim Enabler has issues with kext signing....personally I've left Trim un-enabled and aren't seeing any speed degradation so far...

    I agree here. I went awhile without Trim Enabler and things were pretty much the same, also can't hurt shut it off for the upgrade.

    It's more like a precaution. Just in case something goes wrong during the update process, you will have more chance to boot the machine and fix it. Not a requirement.

    I did the update without disable TRIM, no problem at all. TRIM will be automatically disabled after the updated anyway.
