Make Macbook Pro Hibernate

Extracted from: http://www.geeked.info/make-my-macbook-pro-hibernate/

pmset -g | grep hibernate

This should return one of the following:

• 0 - Legacy sleep mode. It will save everything to RAM upon sleeping but does not support “Safe Sleep”. Very fast sleep.
• 1 - Legacy “Safe Sleep”. This is the “Safe Sleep”. Everything your laptop goes into sleep, it will save everything to harddisk. Slow on Sleep and Startup.
• 3 - Default. As described above, when sleeping, contents are saved to RAM. When battery runs out, hibernate occurs.
• 5 - Behaves as 1 but applicable only for modern Mac that uses “Secure virtual memory”.
• 7 - Behaves as 3 but applicable only for modern Mac that uses “Secure virtual memory”.

Now edit and save your /Users/username/.bash_profile file with the following lines:


alias hibernateon="sudo pmset -a hibernatemode 5"


alias hibernateoff="sudo pmset -a hibernatemode 3"

hibernateon and hibernateoff can be any text you want, you just need to remember what you used.
