RT and MacOS Big Sur / M1 Macs

An observation and a question:

  1. RoastTime 3.0.76 and 3.0.79 seem to be working just fine on MacOS Big Sur (11.0.1). I can find no issues that I would not have found on on Catalina. This is on a 13" 2017 MacBook Pro.

  2. My aforementioned MBP has a permanently dead battery, and I need to send it in for work. During that time, I will have my brand new shiny shiny M1 MacBook Air. Has anyone tested RT on an M1 (Apple Silicon) machine? I would assume it would run in Rosetta, but are there any issues? Or, am I the sacrificial lamb? :fearful:

I’m also very interested in this. I would love to replace my 2015 12” MacBook with an M1 MacBook Air, but am hesitant to upgrade to Big Sur.

I am currently running Roast Time on a 2020 MacBook Air running Big Sur. I have not encountered any problems so far.

Big Sur isn’t an issue, you can run that on your current MacBook with no problems. Roastime works fine on it, I’ve done about 20 roasts with it.

The M1 should be fine, providing that Roastime runs successfully in Rosetta. It won’t run in Universal mode, since it hasn’t been compiled for M1 yet. I think.

Let me clarify a bit: you should be able to use Roastime on your current MacBook, running Big Sur, if your current MacBook can run Big Sur. I don’t know if the 2015 12” is one of those or not. That should be solved with a quick check on the Apple site.

I ran my first couple roasts today with an M1 Mac driving RT. No issues at all — ran just like on my previous laptop.

That’s good to hear. I’ve got my new M1 in, but I haven’t installed RT on it yet.
