So I have tmux installed via arm64 homebrew.
I initially compiled alacritty (my favorite terminal emulator) for arm64 manually, so that's running in arm64 mode. uname -a confirms we're in arm64.
Darwin ndo-mbp.local 20.1.0 Darwin Kernel Version 20.1.0: Sat Oct 31 00:07:10 PDT 2020; root:xnu-7195.50.7~2/RELEASE_ARM64_T8101 arm64
Then I installed homebrew which slowly but surely getting arm64 bottles for most popular applications, including tmux (https://github.com/Homebrew/brew/issues/7857). So I installed that from the arm64 shell, it compiled successfully.
If I run file $(which tmux) I get:
/opt/homebrew/bin/tmux: Mach-O 64-bit executable arm64
However, if I launch that tmux binary in my arm64 alacritty, I seem to land in x86_64 mode. Running uname -a from inside that tmux window I get:
Darwin ndo-mbp.local 20.1.0 Darwin Kernel Version 20.1.0: Sat Oct 31 00:07:10 PDT 2020; root:xnu-7195.50.7~2/RELEASE_ARM64_T8101 x86_64
Any idea what's going on here? I'm relatively new to Mac OS, so maybe I'm missing something obvious.

But in general, x86 apps will not run on an M1 chip ARM CPU. Windows will not run on an M1 Mac.
As of 15 December 2020 Microsoft has made the Office suite of apps (Word, Excel, PowerPoint, OneNote and Outlook) for Macs universal – which means they will run natively on M1 and Intel Macs. However, some elements of Excel were still reliant on Rosetta until January 2021.
We can download VM on M1 with Apple Silicon using UTM. Most Mac users already know that with Silicon chips other Virtual machines will not work. But if you have an intel x86/x64 operating system then they are compatible with other VM as compared to Silicon chip.
Setting up your computer for Vim and Tmux often comes with a few issues. Here's how to manage plugins for Vim and use Tmux to boost your productivity, as well as settle a few common issues.
How to Use tmux on Mac : Get Started Now, you have everything right. Running the command tmux, starts tmux. If you are getting [EXITED], you should check and update your setup. tmux will have own configuration file. These are usual shortcuts for tmux : Ctrl+b ” = horizontally split
Luckily, with the Parallels Desktop 16 for M1 Mac Technical Preview, users can run the latest edition of Windows on ARM. As a no-cost alternative, we’ll also explore how you can run ARM Windows apps using the QEMU open-source emulator and virtual machine application. Here’s how to run ARM Windows on an M1 Mac.
These are usual shortcuts for tmux : Ctrl+b ” = horizontally split Ctrl+b % = vertically split Ctrl+b arrow key = switch pane Ctrl+b c = create a new window Ctrl+b n = Next Ctrl+b p = Previous Ctrl-b o = Switch Ctrl-b ? = All commands There is separate configuration file named .tmux.conf.
It uses Apple’s Hypervisor virtualization framework to run ARM64 operating systems on Apple Silicon at near native speeds. On Intel Macs, x86/x64 operating system can be virtualized. In addition, lower performance emulation is available to run x86/x64 on Apple Silicon as well as ARM64 on Intel.
I had the same problem.
In the end the solution was in the ~/.tmux.conf, add:
set-option -g default-shell /path/to/arm64/zsh
Then kill and restart tmux:
sudo kill -9 [PID of tmux]
tmux
uname -a then returns arm64.

Now that the M1 CPUs have been around for a while and the community has had time to figure things out, I manually cross compiled Alacritty for arm64 as they don't have official binaries yet (Github Actions apparenlty won't build them yet).
But from there, I was in alacritty in arm64 mode (uname -m == arm64 :thumbsup:) and was then able to remove and reinstall brew and tmux the recommended way from their websites.
Followed all instructions and was good to go. I think just having been a bit early and messing around making manual changes here and there threw the whole thing off.
I do have one unrelated problem now however - and that's that tmux won't start as a non-root user. It just immediately crashes haha. When started with sudo, it opens with my expected config and uname -m confirms it is the arm64 version, however I can't get it to start with my normal user. Anyway, problem for another day!
