Edit: Looks like I was using "retinizer" which was causing it to stay in retina mode even with low res checked. I "de-retinized" the app check the setting you mentioned and its now working fine.
For some reason mine is starting without waiting for the extruder or bed to heat up. It starts the heating process, but starts printing immediately. Somehow its ignoring the temps.
I did email support and they said they are not having a problem with their macs. They said they are the very same setup as well. So idk whats going on. I'm just glad Im not the only one because that would mean it would never get fixed.
Ya I just re-installed it. It is "working", but its offset by about 80 mm. I tried taking a screenshot, but it removes the cursor from the screenshot image.
