What this rule does

On MacOS, cmd-tab only toggles between different apps. To toggle between different windows of the same app, you need to use cmd-` . However this is cumbersome for regular usage, as it requires stretching your fingers unnaturally. This rule allows to use cmd-CapsLock instead, which is much easier.

To enable the rule

• Install Karabiner Elements and give it all permissions it asks for
• cd ~/.config/karabiner/assets/complex_modifications and put the json file below there
• Restart Karabiner Elements
• Go to "Complex Modifications > Add rule"

MacOS Big Sur MacBookPro 2020 disable energy drains

Disable settings that prevent the Mac from sleeping or let it wake up overnight in your backpack and drain half of battery.

On top of those, it's probably best to not leave any USB thing plugged to the Mac before putting it to sleep (including YubiKeys).

Enable hibernation (i.e. write to disk)

sudo pmset -a hibernatemode 25
