Calculator widget on notification panel error fix

Calculator widget on notification panel

I'd like to know if anyone found this problem after the upgrade to macOS High Sierra.

The calculator widget on notification panel presents a bug: presents by default the number 475 (not zero).

Scenario 1: (re)start the computer, go to the notification panel and the calculator presents the number 475.

Scenario 2: Press "ac" and the calculator goes to 'zero'. Good. I can make calculations... everything fine. But: a) if I left the notification panel and come back in a short time (5 seconds), the calculator presents the number from the last action; b) but if I come back later (for example one minute), the calculator presents the number 475 (again).

Anyone have a similar bug?

MacBook Pro with Retina display, macOS High Sierra (10.13), null

Go to folder:

~/Library/Containers/com.apple.ncplugin.calculator/Data/Library/Preferences

and delete the file com.apple.ncplugin.calculator.plist

(or make a backup of it and then delete it)

This file is not present in a new installation of macOS High Sierra or in the user library of a new user account. If you open it (for example with Xcode) you'll see that it contains the stuck number.

After that your calculator widget should function normally again.
