Yestarday I installed my Niresh Mavericks 10.9. Everything went fine except thing that I can't "resize" the screen somehow. By that i mean i have a smaller desktop than my monitor actually is. To help you imagine that i'll post a photo of it. Please help and be nice cuz i'm new to all these things. Also I aprecciated a clear explaination how to do it.
PS As a new user should i instantly update to 10.9.3? I tried it once and kernel panic occurced and i had to reinstall everything.
Thanks and have a nice day!
