It is quite simple to correct manually the packaging problem, if you have Gramps 5.2.4, if you are not afraid to look inside the app bundle.
- In the Finder, select the Gramps (5.2.4) app, right click and select “show contents”, then go to Contents>Resources>lib>gdk-pixbuf-2.0>2.10.0>loaders
- In another Finder window, do the same thing with the Gramps (6.0) app. You can see that there is a file named libpixbufloader_svg.dylib (which is a wrong format) while the others are .so
- Copy the libpixbufloader-svg.so file from the 5.2.4 version
- Paste it in the 6.0 version folder
- Go up one step on both windows (Contents>Resources>lib>gdk-pixbuf-2.0>2.10.0) and do the same thing with the cache file (loaders.cache) - you can rename the old one before if you don’t want to write over it
You’re done. Close both windows and launch Gramps 6.0, the missing images will appear…
