Customer Question
MacOS 10.12… Retina iMac…...

MacOS 10.12… Retina iMac… System Preferences crashes when I try to launch it.

Technician's Assistant: What Operating System (OS) are you running on your iMac?

10.12.6

Technician's Assistant: When did you purchase your iMac? What troubleshooting have you tried?

Purchased 2+ years ago. I've deleted the "System Preferences.plist" file multiple times but still no joy. Any advice much appreciated.

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

Before this happened, I was trying to set up a 2nd Apple AirPort Extreme (router) to act as a LAN extender. I connected it via Ethernet to the 1st Airport Extremes, and powered it ON… then re-set the device… tried to access Network Preferences… and System Preferences crashed. It's been like this ever since.

Will Force-Quit System Preferences now.
Mac Support Specialist: Kris R, Computer Hardware Engineer replied 11 months ago

In the Finder, press the key combination shift-command-A to open the Applications folder. Select the System Preferences icon in that folder and press the key combination command-I to open the Info window. There’s a checkbox in the Info window labeled Open in 32-bit mode. Uncheck it, if checked. Close the Info window and the Applications folder. Test.

OK.
I can see that the checkbox "Open in 32 bit mode" is not checked. That box is already empty.

Hey, Kris…
I'm going to check "out" now.
I'll check back "in" later, to update you.
If you have any further ideas, send them along.
Thanks for now.
Mac Support Specialist: Kris R, Computer Hardware Engineer replied 11 months ago

OK great that it's under warranty.

When you do a restore it's only half the system files and it's a light restore - in this case we need to do a full restore

What was it? A repair of the file?

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
