app crashes on macOS BigSur with 'Invalid parameter not satisfying: !isnan(newOrigin.y)'

Ever since BigSur was released, our app starts seeing thousands of crashes for macOS 10.16.0 and 11.0.1

the crash is due to this exception:

  • *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid parameter not satisfying: !isnan(newOrigin.y)'

and the exception backtrace looks like this:

this crash stack is specific to macOS BigSur, it doesn't happen on any of the previous macOS versions (we support all the way back to High Sierra)

I'm trying to hunt this crash down but I'm unable to get any repro of this specific crash.

deducing from the stack trace it looks like AppKit is trying to turn my app's window into a full screen window but I could be wrong.

I was wondering if anyone else had seen similar crash like this?

  • YES Does anyone at Apple know what's going on with this. It seems so many people are having this issue, and no solution to this problem. Please help!

What helped to me is removing saved Safari windows state.

To remove it:

  1. Open Terminal app
  2. Copy&paste this
rm /Users/ivanparfenchuk/Library/Containers/com.apple.Safari/Data/Library/Saved\ Application\ State/com.apple.Safari.savedState/windows.plist
  1. and hit Return.

This is on macOS Big Sur. If the file isn't there, try to search for windows.plist in other places

  • This worked for me and I believe the Safari bug is triggered when the window size is under some threshold.

    You can also browse to that location in Finder and remove the file manually.

This resolved the issue for me. Suggest instead to use a more generic command that would apply to all users and does not contain the user in the path.

rm ~/Library/Containers/com.apple.Safari/Data/Library/Saved\ Application\ State/com.apple.Safari.savedState/windows.plist

Hi hdemuylder, you need to let terminal permit the operation: https://osxdaily.com/2018/10/09/fix-operation-not-permitted-terminal-error-macos/ Then it works
