Sorry we were discussing libqhy issue. The minimum is for the whole build is 10.13. We just found that the qhy issue was that a qhy library that I don’t build was built for 10.15 and that will have to get fixed so it matches the others. If you aren’t using qhy it won’t affect you. We hope to get this fixed soon though.
Hmm, looks like somebody must have made a change to INDI recently that OS X did not like. This must have been very very recent though, since I just built the 3.5.1 beta DMG the other day since a user found that Toupcam was left out of 3.5.0 accidentally. I can take a look at the recent changes.
