Old MacBook as an always-on bot server

Linux, stay-awake and a watchdog turn spare hardware into a home server.

What it does

Give an old laptop that can't run modern software a second life: install lightweight Linux, let your bot keep it awake with the screen dimmed, and add a watchdog so the bot app keeps running 24/7.

Copy-paste prompt

Help me turn an old MacBook into an always-on home server for my bot.

Walk me through it one step at a time and wait for me to confirm each one:
1. Install a lightweight Linux (e.g. Xubuntu).
2. Dim or turn off the screen when idle, but never sleep; recover after a power loss.
3. Install and sign in to the Grok Bot desktop app and start it at login.
4. Add a watchdog that checks the app every minute and restarts it if it stops.
5. Test a scheduled job end to end.
