@ Mike The short answer to your questions: yes, and yes. To date there's only 3 Mac models with the M1 chip: two laptops and the Mac Mini. I've just bought the Mac mini running under Big Sur for dedicated Xcode, which is painfully slow on my old MBA.
Well…! This is the most painless Mac I've ever bought (I own 4 now, some very old). Setup was fast, and went as it should. Mind you, I'd only installed Xcode from App Store and transferred none of my code and data. I hadn't even installed J. But seeing your post I thought I'd install first j901 then j902. Both installations proceeded identically, and just as they had for my MBA running Catalina. I wrote a log as I did the steps, which I'll omit here. Ask to see it if you want. Basically I followed the instructions on the jwiki page: System/Installation/j902/zips first clicking the link: j902_mac64.zip Once installed, j902 offered me 3 icons on my desktop. I ran the green J named jqt902. After 24 bounces in the Dock, the jqt "Term" window appeared. (don't worry: it re-launches with scarcely one bounce.) I then entered: load'plot' plot 2000?2000 The plot window appeared immediately, filled with a dense scribble. Summary: the Mac mini runs absurdly fast, and I've found it no trouble to use. To-date it has done everything I've thrown at it. Bill is right: there's no J engine for the M1 chip as-yet. So it's got to be transparently running the new Rosetta emulator for Intel code. I haven't timed any J benchmarks: would someone care to offer me one? Ian Clark On Sat, 13 Mar 2021 at 20:00, Michael P.
