Cura 3.5.1 not starting on Mac OS 10.9.5

[cajodo 1]

The program is in the Program folder, first time the Mac asked me, if I want to start Cura, because, it is from the internet. I agreed. Then the symbol appears, and is gone within 1-2 seconds.

The next programstarts same procedure, the GUI will not appear. A SpashScreen with VersionNumber is also not visible.

And before you ask: Mac is rebooted ... thx for help

Not 100% sure, but I think you have to use an older version of Cura which is still working with Maverick. Your OS is quite old and as far as I know with 3.5 there was a change to a new version of a library which is not working anymore with older version of MacOS.

For me it doesn't work on 10.11.6 either.

I upgraded my Mac  Airbook to Mac OS 10.14.1 (Mojave) and tried to run Cura 3.5.1.  It wouldn't start, giving me an error message.  It runs fine on my iMac running the same operating system.  Any thoughts on why there might be a difference?

Which error message do you see?

Turns out if I had followed their suggestion in the first place I wouldn't have this problem.  So I did what the instructions suggested and backup and restored the configuration file.  Then it loaded without a problem.  Thanks for offering your help anyhow.
