Default Re: Slow High Sierra boot - solved

Resetting the Parameter RAM is the first thing I do with any new Mac OS install. It even speeds up a fresh virgin install of Mac OS X.

Im surprised youd never come across that before. Its quite a well documented fix for a lot of things.

Now run Diskwarrior on the drive and shave another second or two off. :)
