New Macs all have the same software installed. If you are referring to Garageband (See links below) then yes both the MacBook and MacBook Pro have it installed.
Garageband is strictly only available for the apple made computers. Computers that qualify: - MacBook Air - MacBook Pro - Mac Mini - iMac - Mac Pro If you do not have any of these computers you are out of luck.
Find it physically or make it function?
Garageband should be in the Applications folder of every MacBook.
Ebay
MacBook Pro is the best you can get
Noplace.
MacBook Pro!
The macbook pro!
you probably should get the MacBook. they are cheaper than the MacBook Pro. now, if you want a bigger screen, then get a MacBook Pro.
Unfortunately the MacBook Pro seldom sells for a reduced price. If you are looking to find the best price for a MacBook Pro I would suggest checking Amazon, or the online auctions on EBay.
There is no age limit for getting a MacBook Pro.
