Mac-to-Mac Remote Shell Stack (Tailscale + SSH + Mosh + tmux) — Low-Lag, High-Reliability Setup

This gist documents a reproducible setup for a “remote shell that feels local” between a laptop and one or more headless Macs (e.g., Mac minis). It is optimized for:

High latency / packet loss links (SSH typing lag, key repeats, “rubber band” echo)
Roaming networks (Wi-Fi drops, IP changes)
Long-lived sessions (detach/reattach, crash tolerance)

Core design decisions:

Tailscale provides a private, encrypted, stable network plane (no port forwarding/NAT complexity).
OpenSSH (Remote Login) is used for authentication, key management, and compatibility.

	# Initialize arrays to store results
	successful_updates=()
	failed_updates=()
	skipped_repos=()
	no_git_repos=()

	#!/bin/bash

	# Set IFS to prevent word splitting issues with spaces in paths
	IFS=''

	# Use git ls-files -z and a while loop with null delimiter
	# The '-d $'\0'' tells read to use null character as delimiter
	# The '-r' prevents backslash escapes from being interpreted
	git ls-files -z \| while IFS= read -r -d $'\0' file_path; do
