Hi Mahmoud, welcome to the site. And good look with your forthcoming Mac. You could benefit of being a member of the
EmiratesMac Apple User Group: you would get discount on purchase of the Mac and you could come to our monthly meetings to get help with the Mac. We also offer
training for beginners once a month, that may be of interest too. Also there are usually some articles for beginners in
Shuffle, our monthly newsletter.
A hint for the future, it's better to put a new message as a new thread, rather to post in an existing, unrelated thread. If you post in an existing thread, there's a risk that your message isn't read.
