If your Mac runs the Leopard operating system, then this comes with a useful program called Boot Camp.

Boot Camp allows you to install and run Windows XP or Windows Vista on your Mac. Therefore, ensure you have retained your Windows XP or Vista installation CD.

Under Boot Camp, you can switch between the Mac desktop and the Windows XP/Vista desktop.

When running in Windows mode, Ace Payroll runs as per normal - everything works as if you were using a PC.

There are no costs involved in using Boot Camp - it comes with your Leopard operating system.

The only "problem" some people find with a solution like Boot Camp is that you need to switch between the Mac and Windows desktops when you want to run a Windows program like Ace Payroll.

One way to avoid this is a program called Parallels Desktop for Mac.

The concept is the same as Boot Camp - you can run Windows programs. The difference is you run them straight from your Mac desktop - there is no need to switch into Windows mode.

This means you really are getting the best of both worlds - the use of Apple's computer and operating system, whilst running any Windows program alongside your Mac programs.

The only downside is that you would need to purchase Parallels whereas Boot Camp is free.
