Apple’s Store is back up and Mac OS X 10.7 ‘Lion’ is now available for purchase and from the Mac App Store. Mac OS X 10.7 ‘Lion’ costs $29.99, but it can be run on up to five machines as long as they share the same Apple ID.
The download is 4GB so if you’re downloading, be patient! If this is too big for you, Mac OS X 10.7 will be available on a USB flash drive come August, or you can go into an Apple Store and use internal WiFi to carry out the download. Minimum spec for Lion is a Mac with an Core 2 Duo, Core-i series or Xeon processor (no Core Duo or PowerPC support) and 2GB of RAM.
