Since Yosemite came along, I have noticed that on occasion my iMac can take an absolute age to boot, sitting with a blank light grey screen for sometimes 2 or 3 minutes with no indication on screen whether it is doing anything at all....!

Is that usual?

The machine is quad core i7, 32 Gb RAM and has the Fusion Disk so is normally fairly fast.

It might be checking an external hard drive? You've mentioned these in previous

Check your start up drive in Preferences - set it to another one and back again

It only shows Macintosh HD as an option.

Did you upgrade to Yosemite or do a fresh install?

No issues on mine, boots in 10 seconds or less most of the time. And mine is ooooold - 2011 MBA.

Could be disk health, or something else hardware related.

SMC Reset should be your first stop.

Is it selected (ie. is the text highlighted)?

Yes it is selected.

I think the instal was an App Store upgrade. It shipped with Mavericks I think.

Set it again in Preferences --> startup disk - select the boot drive and click "Restart..." . May not work in your case but worth a try

I'm trying to create a bootable drive but the process strays into areas that are a bit tech for me, like using the Terminal commands etc.

I am surprised Apple did not make it a more simple exercise than this.

Please do an SMC Reset before you do anything else. It fixes tons of hardware/firmware related issues. At least if it's done and you're still having problems you can rule it out but it's so quick and easy and fixes so much it's mad not to try it.

So I did the SMC, which seemed to make little difference (although pulling the plug out for 15 seconds is at least simple and easy!!).

I then re-installed Yosemite having found step by step instructions for making a bootable thingy from my handy USB stick. Worked fine and I have to say it is much faster now than it was. Still in my recollection slower than Mavericks was though.

I get the Grey screen and small progress bar that is there for about 30 seconds then it moves on, it takes about a minute to boot. My big issue is with the spinning ball which I am getting in increasing frequency.

No spinning ball yet but otherwise the same. Not sure where that silly progress bar suddenly came from. Cant see a point for that - it has never been there before.
