Operating System

When selecting a computer, the first step is to select the operating system. There are two main operating systems to use:
  • Mac OS ®
  • Microsoft ® Windows ®
Deciding which operating system to use is based on your preference. If you’re upgrading your computer, stick with the same operating system so you don’t have to purchase another license for the software you already have. Otherwise, ask yourself the following questions:
  1. Which operating system am I most comfortable with?
  2. Is there any software I need to use that’s only available in a specific operating system? (ex. Apple Aperture)
Photoshop does not perform its best when used with Microsoft Windows Vista RC1. Although Photoshop is compatible with Windows Vista RC1, there may be some performance issues. For example, opening the “Save for Web” tool takes longer to load than Windows XP. With that said, keep in mind that Windows Vista is currently still being worked on and many bugs and tweaks should be resolved in the finalized version.  

64-bit

64-bit computing allows Photoshop to use approximately 3.5 GB of RAM. If you will be using more than 2GB of RAM, make sure that you use a 64-bit operating system such as Mac OS X, Windows XP 64-bit Edition, or Windows Vista 64-bit Edition. Generally, we recommend investing in 64-bit hardware and software to adapt to the new generation of computers.
