Oh that's not good. I wish I had some good advice but I don't. Let us know what they say! Is your internet connection, router is goo shape?

I ran a hardware test and nothing was found. I'm at a loss as to what's wrong. Once it stops raining, I'm talking it into the repair shop. I hate having computer problems. Good thing I did a back up recently.

@glb613 (Dumb question, since I know you're highly skilled in iMacs). Have you called Apple Customer Service? I've always found them very helpful, even when I thought I no longer had C/S coverage from them. (Just a thought.)

I wish you good luck in resolving your problem. MAC's are usually trouble free.

@glb613 You are so far above me tech wise... I wanted to get a Mac and am now worried....if you are having issues then I would be totally lost.... I was sure you bought a brand new Mac...

You are highly respected here. Your word is gold to me.

What year is the iMac? Just curious.

Udate: It's in the shop. The tech got it to booted like normal when he used their network hard drive. It wouldn't boot from its own hard drive so, I'm having them run a complete diagnostics and format/reinstall the operating system. I'm having them install Sierra instead of High Seirra. I have a game (Clue) and a portable scanner that won't work with High Seirra. I'm thinking of restoring my Macbook to Seirra but will wait until my iMac is out of the shop.

My iMac is 5 years old and has been a work horse for me. I won't let this problem stop me from buying another iMac. I ran diagnostic tests at home and it showed everything is fine. The same thing happened at the shop. The repair shop can run a more intensive diagnostic testing the the ones included in the operating system. I think it's a corrupted operating system and if it is, I have no idea how it happened.

@glb613, sadly I have no advice but I feel your pain. LM

Update:

There is nothing wrong with the iMac. All of the diagnostic tests showed no hardware problems. It was a corrupted operating system caused by installing High Sierra. It's home and I will get it up and running starting tomorrow. I'll be glad to get everything installed so I can format and restore my Macbook Pro.

Why would installing High Sierra cause problems?

@glb613, just as an FYI, I had an appointment at the Genius Bar yesterday about my jumping cursor. I will update on my other post about that issue but wanted to mention here that they keep telling me not to install High Sierra. Although I am pretty sure it is because there are issues with it, they didn't come right out and say that. Good luck! LM

My computer is almost 5 years old. High Sierra is more than the computer can handle. The tech said the age of my computers is why I'm having problems. Plus I wanted to go back to Sierra because several games I love to play and a portable scanner I use weren't compatible.

That's interesting. Our mid-2011 iMac is running fine on High Sierra. Better than ever.

I have read about problems with it - fortunately doesn't seem to affect me.

Good luck; I hope you get things fixed.

My understanding from her previous posts is that it was putting a much larger demand on her CPU than the older operating system. Her fan was running more and longer and her older CPU just wasn't able to keep up.

Operating system writers tend to stress out computer hardware. The CPU on my current computer (an AMD FX 6800) has six cores each operating at 3.5 ghz and capable of boosting up to 4.1 ghz. My first real PC had a 100 mhz single core processor. So, each core on my newer CPU (which by the way is far from a brand new CPU) runs 35 times faster than that first CPU did. (Faster than that really due to other reasons but for the sake of this discussion we'll say 35 times faster.)

That old computer had a 1.2 gb hard drive and held two operating systems (Windows 3.11 and Windows 95) along with about seven years of my writing and assorted other data. Windows 10 (and most newer operating systems) need around 15-20 gb's just to install and run. Windows 95 reportedly used between 50 and 100 megs to install. So while CPU speeds have increased 35 fold (or more) the operating systems have grown in size from maybe 100 megs to 20 gigs, or roughly two hundred times. That's why using a computer is about the same as it was twenty plus years ago. Those creating the operating systems eat up every bit of speed the hardware makers gain.

Put a Windows 95 size operating system inside modern hardware and you'll have a lightning fast computer. (Which is largely what Google does with their Chrome OS and their Chromebooks, Chromeboxes, and Chromebits.) Look at the hardware they use for their computer and youll laugh at how old and slow it us. Use one of the Chrome devices and you'll marvel at how fast and responsive it is. Why is it so fast and responsive with such "slow" hardware? It's got a very simple OS. Funny how that works.

@ Montana, not related to this post but I understand there definitely are some bugs to be worked out with High Sierra. I have an issue unrelated and Apple will not let me install High Sierra until January when, hopefully, they will be addressed. I have a 2015 MacBook Pro. This as an FYI. LM

So far, so good. Of course Apple wants to install the latest operating system. I've stopped it for now but, I'm afraid it will install and I DON'T WANT IT. I downloaded the Clue game and it works. I hope the other games and apps I own that don't work with High Sierra will be usable again. I decided to manually install of my my apps and files. I had way too many things on the computer, I have everything saved and if I need something, I know where to find it.

I installed an older verion of Firefox and it automatically updated the the newest version. So, I'm going to uninstall then reinstall the old one with it set to not automatically update. The newer version is making my computers run hot.

It's going to take a while to get everything back on the iMac because I want to be selective. I have a lot of data and downloads I really don't need. Once it's done, I'm going to restore my Macbook Pro from a backup.

I've done restores many times when I owned a Windows based computer. I've also done a lot for other people. This is the first one on an Apple computer and it realy isn't much different. At leaset with Apple, I didn't have to install drivers and a gazillion Windows updates. I really wish Apple had system restore. It would be a lot easier.

@glb613, good luck! I didn't realize Apple doesn't do system restore. LM

I'm talking about having a system restore like Windows does or did. Where you go back in time, sometimes a day or two, when something goes wrong. Apple has a restore but it's more like a format and reinstalled.
