Hi all,
I (with lots of help from su_v) have been working on getting the macOS DMG build working again with a view to having an official DMG ready for the future 0.92.2 release.
The current _unofficial_ test build of 0.92.1 is available here:
https://inkscape.org/en/~tghs/%E2%98%85inkscape-0921-tghs_2-x11-107-x86_64dm...
Included in this build is a new feature to automatically set the recommended XQuartz configuration. You'll be prompted about this on launch if you've got XQuartz running in its default configuration. This used to have to be set manually, as documented here: https://inkscape.org/en/download/mac-os/.
Any feedback is welcome. Since it's a test build, please don't file any bugs; reply in this thread, or contact me directly by email. I'm also around in both the #inkscape and #inkscape-devel IRC channels.
Cheers, Tim
