As of this week's v10.15 release, MacOS is no longer capable of running the 32-bit Astroconda IRAF distribution needed by Gemini IRAF. For the time being, Gemini IRAF users on Apple machines are advised to continue using MacOS 10.14 or earlier, or to install Astroconda in a virtual machine with a compatible OS. Gemini will look into providing a ready-made VM image to help with this while we are migrating our data reduction tools to Python. Furthermore, MacOS 10.14.6 suffers from a bug that can cause a desktop session logout when attempting to display plots or images with PyRAF, DS9, Matplotlib or other software that uses Tk. We suggest that PyRAF users on 10.14 avoid updating their OS until such time as this problem is resolved by Apple and/or we can determine a reliable workaround (check here for further announcements). IRAF CL is unaffected, but note that we are no longer testing it routinely and are aware of occasional failures with Gemini IRAF.
