Computers get greeked either because you do not have permission to feature the product, are using a differnt brand elsewhere in the project (or as a sponcer), or there was going to be product placement, but then it fell through.
The computers chosen (as well as other props) are either carefully picked by the art director and props to fit the character and scene, or are simply just whatever they happen to have on hand and used because it was cheeper than buying something just for the project.
Another reason is that sometimes software is ran on the prop computer that makes it look like the actor is doing something. Sometimes the software used will only run on a pc or mac, often it is mac only, so a mac is used but left generic looking.
