Hi , first time macbook air 13 inch owner here. I have used windows xp, 7 and ubuntu but its my first time using mac lion. I have a long list of questions here, hope somebody can answer them please. a. When youre in full screen , lets say in safari, what is the best way to hide safari or unable the full screen mode ? Is it possible thru gestures? b. What are mac freeware alternatives to > winzip > any ftp program > winamp > ftp software > notepad ++ > any budgeting/personal finance programs out there? or can you point to a list of essential mac apps after a fresh install of lion ? c. If you use Adobe Fireworks in a mac, and you have also used the windows version, you will notice the toolbars ( undo, redo , the bring to back/front ) buttons are not in the mac version. It was a real shocker for me when I found out it wasn't there, is there a panel extension for this or should I use keyboard commands ? d. I want to change the icons for the programs and folders, lets say in the dock and desktop, how do I do this ? e. Do I need to install antivirus programs /anti malware programs like ad aware or I don't ? f. Any tips to make the macbook air even faster ( like in windows you can disable services in msconfig, etc ) Thanks !
