Yosemite Hangup

I loaded Yosemite on my iMac and Macbook pro with no issues. Loaded on my wife's iMac and now all I get is a white/blank screen. I powered-off and turned on again with the same result. Her iMac is apparently locked up. How do I fix this? (before she tries to use it).

Seems that since you already successfully installed Yosemite on two of your computers…that you should almost be an expert yourself!

What's the deal with your wife's iMac:

- What model is it (is it compatible with Yosemite)?
- How full is this iMac's hard drive?

Like I mentioned. Since you successfully installed Yosemite twice…and since you are much more familiar with the workings of your wife's iMac…you're certainly in a much better position to figure this out.

I think that we need more info before we can start making guess's/solutions.

My wife's iMac is newer than mine, maybe a couple years old and has lots of memory (even if it didn't, I would suppose that this would be flagged during the Yosemite installation process, maybe). I just checked again and the white/blank screen remains. The little spinning "busy" circle is spinning. This may indicate that the computer is doing something or that it is, indeed, locked-up. Maybe I should just wait a day and see it it works itself out. If you need additional info, let me know what you need.

A couple of years and lots of memory don't fill the bill alas. And how much free space on the hard drive.

"Memory" is not a synonym for "hard drive" or "storage."

The iMac specs: 2.7GHz Quad-core Intel Core i5 Processor; 4GB of 1333MHz DDR3 SDRAM; 1 TB 7200RPM hard drive. Since I can't get it going, I can't tell how much memory is left, but I doubt that it's even approaching a quarter of that 1 TB. It's backed up thru Time Machine to a 2 TB My Book for Mac.
When I boot up, it shows the Apple logo and a loading bar beneath that progresses about a quarter of the way before the screen goes to white/blank. The spinning circle appears rather than a cursor, which seems to indicate to me that something is trying to load, but never gets there.
I may just take it to my Apple repair shop next week, unless there is a magic "fix it" key that I can press on boot-up.

You have 4 gig of memory.

Boot into Recovery (Command + R and go to utilities > Disk Utility and run Repair Disk and see what is reported. Also 4GB is miniscule suggest going up to 8GB at least to see a huge improvement.

To Harryb2448: thanks for the tip, will try it. With regard to 8GB+ vs my 4GB, is this a hardware installation or is it something other than that?

That is indeed a hardware installation. As soon as I can pin it down I'll post the installation instructions to give you an idea how it is done.
