CNET - Apple's OS X Lion released today, and for the first time, the only way to grab a copy is through the Mac App Store. While this convenience might encourage you to upgrade immediately (for the price of $29), we've got a short checklist of things you need to do before installing Lion.
1. Check system requirements.Is your system even compatible with Lion? Go to the Apple menu > About the Mac to find out. You'll need:
- Intel Core 2 Duo, Core i3, or Core i5, Core i7, or Xeon Processor
- 2GB of RAM (aka "Memory")
- Mac OS X 10.6.6 or later (Snow Leopard), including the Mac App Store
- At least 4GB of storage for Lion
