It came to our attention that for a period Teslagrad could no longer run on new installations of the Mac operating system.
We work hard to make our games as available as possible, so we have released a patch. This is now tested and seems to have solved the issue entirely!
For anyone who had a bad experience getting Teslagrad to work for Mac in the recent months: We are sorry for the inconvenience. If you update Teslagrad on Steam now, all issues should be fixed.
Happy Playing!
