How to fix rearrangement of display screen/spaces on Mac?

Sometimes i get irritated when i see the arrangement of spaces or screen changes when i want to switch between screens on Mac. I always try to ask how do you prevent the macos from occasionally changing or resetting the display arrangement on its own upon waking up or a reboot?

The solution is simple:

Go to Apple > System Preferences > 

Mission Control > un-check "Automatically rearrange spaces" 

and "Displays have separate spaces" 

Cheers :)

Taking screen shot in Mac OSx

Taking screenshot in windows is very simple. A keypress can do that but on Mac it requires a combination of keys. But on the other hand, the added advantage in Mac is that you can select the area under screen shot very easily.

1) Taking full screen shot
Command[Apple] + shift + 3 = take a screen shot. The screen shot will be automatically saved as a PNG file on your desktop.

2) Taking selective area screenshot
The same instead of 4 brings up a cross and can take a screen shot of a selection. A cross-hair cursor will appear and you can click and drag to select the area you wish to capture.

3) Taking screenshot of an application window
To capture a specific application window, press Command-Shift-4, then press the Spacebar. The cursor will become a camera, and you can move it around the screen. On moving cursor over an application window, the window will be highlighted. When you have the cursor over a window you want to capture, just click the mouse button and the screen shot will be saved as a PNG file on your desktop
