For those planning to upgrade to 10.10.1

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.

Same here.
