Use iMac as display for MacBook Air

There are 2 options to connect MacBook Air to your iMac.

Firstly by using mini displayPort cable and connect the 2 mac’s. Just display and audio will be transferred via the cable.

Secondly, use share screen option (this will be bit slow since all communication of data will be done via LAN)

To do this:

1. On MacBook Air

Go to System Preferences > Sharing
Tick “Screen Sharing”
Allow access for “only these users”. Choose a few.
Set the “Computer Name”

2. On iMac

Open spotlight. Type “Screen Sharing”
Type the computer name you want to connect to
Or go to Finder and double click on the computer under “Shared” category (sidebar)

Different type of sleep mode on Mac

Go to terminal, type this command line

pmset -g | grep hibernatemode

The result will be either of the following

0 = normal sleep for desktop (save in memory. use low power)
1 = hibernate (save in hard disk. total off)
3 = safe sleep (save in memory and hard disk. use low power)

To change, type this command line,

sudo pmset -a hibernatemode X

(X to replace with either 0, 1 or 3)
