Can I use a regular external hard drive for a mac?

Julia

I just bought a mac and I want to back it up, but I'm not sure if I can buy a regular external hard drive or do I need to buy one that is specific for mac.

Answer
You can connect any USB drive to your mac, you may need to reformat it so the mac can read and write to it.

To do this launch Disk Utilities (Applications>Utilities folder) and click on the icon for the removable hard drive. Select Erase and set format to Mac OS Extended (Journalled).

Some manufacturers sell specific mac hard drives but these tend to cost more - not worth the difference when all you have to do is reformat it.

Can I download a Mac App to an external hard drive?

I want to download Call of Duty 4 for my Mac but I don't want it to take up my RAM, etc. Am I able to download it straight to my external hard drive and when I want to play it, plug the hard drive in and start it up?

Answer
Sorry, but I wanted to do the same thing. It is not possible to INSTALL anything on an external hard drive not running Mac OSX. In order to do this, you will have to download the game (you can download it to your external hard drive), then install it on the Mac's internal hard drive, THEN drag it back over to the external hard drive. That is the only way, unless you can somehow run Mac OSX on the hard drive.
Hope this helps!

Cheers
