Omarchy on a second Mac via Grok Build over SSH

Installing Omarchy

Plugged my M5 Max MacBook into an M2 Pro MacBook with a single Thunderbolt cable and had Grok Build install Linux on the second machine over SSH.

Never touched the target's keyboard until the very last step. 🧵

Prompt below if you want to try it. 👇

The prompt

I have two Macs connected by a Thunderbolt cable. This one is the host. The other is the target, and I want to install Omarchy on it alongside macOS. Before changing anything:

1. Find the target over the Thunderbolt bridge and confirm you can SSH to it. Report its model, chip, macOS version, and full partition map.

2. Tell me what is ALREADY installed on it, including leftover bootloader stubs from previous attempts. Do not trust my notes, read the disk.

3. Check whether Omarchy actually supports Apple Silicon / aarch64. If it ships no ARM installer, tell me the real supported path instead of improvising one. Before deleting anything:

4. Pin every partition you plan to delete by partition UUID, never by disk identifier. macOS renumbers partitions the moment one is deleted.

5. Check NVRAM boot-volume with `nvram -p` (plain `nvram boot-volume` errors out). The UUID is stored byte-swapped. If it points at a partition on your delete list, fix Startup Disk first and VERIFY it before proceeding.

6. Give me a dry run printing every command, plus a preflight that names the partitions which must survive and aborts if any is missing. Stop and ask before the first destructive command. Tell me plainly which steps require me to be physically at the target machine.
