The .designspace file is not recognized by Glyphs

Hi, when I drop a .designspace file onto Glyphs (Version 2.6.5 (1342) on MacOS 10.15.5) all goes well! When my colleague tries this with the same .designspace file running the same version of Glyphs and MacOS the file does not open and instead she gets the message ‘The document “SuchANiceFont.designspace” could not be opened. Glyphs cannot open files in the “DesignSpace Document” format.’ Do you have any idea why that is?

Just the .designspace file? Or with the connected UFOs?

It might be that the file type registry is not right.
you can check it by this command:

/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -dump

It will result in a lot text. Search in the Terminal for “designspace”.

and reset it to default settings.

/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister  -kill -r -domain local -domain system -domain user

Thanks @mekkablue and @GeorgSeifert , I’ll have another look what this might be caused by.

My colleague has reinstalled Glyphs and all works as expected now.
