KiCad 8 installed on Mac OSX can not run

As long time user of KiCad 4 - 7 I recently installed KiCad 8.01 from the download dmg. The main project window opens as usual but neither Schematic or PCB editors will execute.

Receive error message “Application cannot start” with content:

16:24:47: Unhandled exception class: N8pybind1117error_already_setE what: OSError: [Errno 34] Result too large: ‘/private/var/folders/b0/9qh_ncvd32b4k024r616n8vr0000gp/T/AppTranslocation/DB448E19-5BB3-4DB5-901F-91AC3E3809C0/d’

Seems the new version is running amok with OSX security. Any suggestions?

Read this, report back:

Did not work for me. If I run /Applications/KiCad/KiCad.app, I get the error described.

However if I run /Applications/KiCad/KiCad.app/Contents/MacOS/kicad everything works. It opens a terminal window and runs the code.

The terminal window shows:

/Applications/KiCad/KiCad.app/Contents/MacOS/kicad ; exit;
2024-03-29 11:43:29.644 kicad[10571:616349] WARNING: Secure coding is not enabled for restorable state! Enable secure coding by implementing NSApplicationDelegate.applicationSupportsSecureRestorableState: and returning YES.

I’ve been running KiCad 7.02 for quite some time without any of these issues. But I just downloaded 7.011 and it shows the same problems as 8.01. Don’t know if something changed in MacOS security or in the KiCad dmg production. I get the same result on Mac OS V14 on Intel and Mac OS 12 on M1.

You tried the
sudo xattr -dr com.apple.quarantine /Applications/KiCad/KiCad.app
command?

Because, I’m running 8.0 on an M1 Mac.

Perfect. That did the trick. All good now.

Thank you
