How to Install Mac OS X Lion - Digital Web

Apple has released the newest Mac OS X Lion today. You can upgrade your current Mac OS X and replace it or install a new one. The only way to grab the copy is through the Mac App Store. Before you install it on your mac you have to check your hardware and software requirement.



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

2. Install software updates. Go to the Apple menu > Software Update, and download and install all the recommended software.
3. Back up your Mac. Before installing Lion, back up your system, as a new operating system can sometimes result in corruption. We recommend using Time Machine, but you can find step-by-step instructions for other options here.
4. Do a little app maintenance. As MacFixit's Topher Kessler suggests, uninstall any apps and add-ons you don't use (including apps that run in the background and apps that tweak your operating system). Then head to Roaring Apps and check to see if the applications you keep are compatible with Lion.
5. Check your hard drive's health. How is your hard drive feeling? Go to Disk Utility (searchable in Spotlight) and select your hard drive in the left sidebar. Then, at the bottom right, select "Verify Disk". If everything's OK, Disk Utility will tell you--otherwise, follow the onscreen instructions for repairing your drive.
