MacOS Clamshell mode on battery power.

Propably most pleasant way to switch your Macbook machine between clamshell mode without power adapter.

Create "no-Sleep" shortcut to prevent macbook going sleep after closing the lid.

1. sudo pmset -a sleep 0
2. sudo pmset -a disablesleep 1
3. sudo pmset -a displaysleep 5 (sleep timer set to 5 mins)

Create "Sleep" shortcut to get back to default sleep settings.

1. sudo pmset -a sleep 1
2. sudo pmset -a disablesleep 0
3. sudo pmset -a displaysleep 1 (change if you want different sleep timer)

Add shortcuts to menu bar simply dropping them to "MENU BAR" folder

TroubleShooting

1. Remeber to check "Run as administrator" box to run the commands with proper permissions.
2. If your screen goes sleep mode, you have to open the lid to wake up machine (trying to find a solution for that)
