EstiMate works on any relatively modern PC running
Windows XP-Windows 7.
EstiMate also works flawlessly on Intel based Macs using VMWare Fusion for Mac OS X.
We love Macs too – however, because our industry has always been traditionally PC-based, EstiMate is and will continue to be Microsoft Windows software. However, the world is changing and software is becoming more universal every day.
Surprise fact: EstiMate is actually developed on a Mac Pro running VMWare Fusion, and for a while EstiMate 2 was developed on a MacBook Pro running Fusion! Bottom line, EstiMate runs flawlessly in Fusion, and in many cases, better than on a PC due to the quality architecture of Mac computers.
Just sayin'.
