In preparing to move off my 2017 Intel iMac (and put if for sale), I must make sure to re-install remaining applications on my M1 Mac mini. Photography-related apps were the last to be updated for the M1 chip. Lightroom CC is now fully optimized, but none of the Skylum apps I was (rarely) using: Luminar 4 and Aurora 2019 HDR. After spending some time on their support forums, I found out that none of their apps are optimized for the M1 chip. I had to make the call: bye bye Skylum. I barely knew you.
If a software vendor like Skylum is unable to update their apps in a timely matter, more than a year after the M1 chip has been announced, I give up. It is sad because these are the kind of applications that would take advantage of the power of the M1 chip. Too bad. My photography workflow will focus on Adobe applications, for good or for worse.
