How to Get 64

Mac Users
1. Click on the 'System Preferences' application.
2. Click on the 'Displays' pane. This will show your display settings. According to Apple, the Snow Leopard Operating System utilizes 64-bit technology; however, if you're running an older operating system you will be limited to 32-bit colors and you need to upgrade to Snow Leopard.
3. Set the colors option to '64-bit.' Your Mac is now ready for 64-bit color displays. However, keep in mind that some older programs are not 64-bit capable and will still display in 32-bit.

4. Make sure your PC is running the 64-bit edition of Windows Vista. Unlike Snow Leopard, which is universally 64-bit, Windows Vista comes in both 32-bit and 64-bit versions. If you do not have the 64-bit edition, you can upgrade; however, keep in mind that your PC will need at least 4GB of memory to support 64-bit functionality.
5. Right-click on the Windows desktop.
6. Click to select 'Personalize.' This will open a new window.
7. Click on 'Display Settings,' typically located at the very bottom of the Personalization window.
8. Click on the drop-down menu underneath the 'Colors' heading and select '64-bit,' then click 'OK' to confirm the change to 64-bit. Remember that not all programs are 64-bit capable; some older programs may still display in 32-bit even after you get 64-bit colors.
