Lion includes many new features that enhance functionality for end users. Several of these enhancements change OS X behaviors present in Leopard (10.5) and Snow Leopard (10.6). Among the most notable for the MIT community are changes to Kerberos, wired DHCP and user navigation. A full list of new features can be found on Apple’s website.
The minimum system requirements to run OS X Lion are as follows:
- Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor
- 2GB of memory
- 7GB of available space
- If upgrading: OS X 10.6.6 or later (10.6.8 recommended)
IS&T has purchased a fixed number of Lion licenses for MIT faculty and staff for use on MIT-owned equipment. Lion can be downloaded, free of charge, from IS&T's Available Software website. IS&T suggests that those planning to upgrade their machine(s) within the next calendar year not install Lion using MIT's volume license.
Documentation about Mac OS X Lion — including upgrade instructions — can be found in the Hermes knowledge base. Users should run Software Update immediately after installing Lion to be updated to 10.7.2.
