Hardware Requirements
For starters, you need to make sure you and your Mac have what it takes to handle Mac OS X Lion—specifically:
A Mac with a recent Intel processor. Those old PowerPC Macs (PowerBooks, iBooks, PowerMacs, eMacs, and pre-2006 iMacs and Mac minis) have finally fallen off the Mac OS X upgrade path. You need a Mac with an Intel Core 2 Duo, i3, i5, i7, or Xeon chip inside; if you have a Core Solo or Core Duo processor instead, you can’t install Lion. (How do you find out? Choose
→About This Mac. The resulting dialog box
clearly identifies your processor.)Basically, most Macs manufactured since late 2006 are eligible.
Mac OS X Snow Leopard. Your Mac has to be running the most recent pre-Lion software version, Mac OS X 10.6 (Snow Leopard). (The main reason: You need the App Store to get Lion, and the App Store debuted in Snow Leopard.) Even if you already have Snow Leopard, run Software Update to make sure you have the latest version, 10.6.8.
If you don’t have Snow Leopard, then the cost of Lion just went up. You’ll have to buy and install Snow Leopard and then buy and install Lion.
Tip
OK, technically, you can install Lion onto a Mac that has Mac OS X 10.5 (Leopard)—by doing a clean install. See The Setup Assistant.
