Customer Question
I recently downloaded High...

I recently downloaded High Sierra to my mac. After I did, most of my most useful software quit working. I want to remove High Sierra. I found directions to revert to the original mac software which I followed. It seemed to be working, when there was a power hiccough. When I repeated the procedure, I got an error message: -2100F. Can you help me, please?

Technician's Assistant: Did the application come with an uninstaller, either on the installation disc or in the application's folder on your Mac?

I could not find an uninstaller for the new Mac OS.

Technician's Assistant: Anything else you want the Software Expert to know before I connect you?

Don't think so, thanks

Hello,

Thank you for contacting JustAnswer.com, my name is ***** ***** I am a Mac Specialist and IT Tutor for over 15 years. I will be more than happy to assist you with your support request.

My apologies for the issues you are having with your update to macOS High Sierra. I will do what I can to get your question resolved.

I have just a few quick questions:

• Can you give me an idea of what applications/software you have been using, prior to upgrading to macOS High Sierra, that is now no longer working?

• When you mention "repeated the procedure" are you referring to attempting to reinstall Mac OS High Sierra to correct the issues with the previous version of this OS?

Thanks in advance for your responses, as your feedback will enable me to determine the most probable solution to help you.

-TD

What Customers are Saying:

Hi John, Thank you for your expertise and, more important, for your kindness because they make me, almost, look forward to my next computer problem. After the next problem comes, I'll be delighted to correspond again with you. I'm told that I excel at programing. But system administration has never been one of my talents. So it's great to have an expert to rely on when the computer decides to stump me. God bless, Bill
