Mac OSX Lion 10.7 Differences

What's Different from Snow Leopard

  • Rosetta is no longer available. This means PowerPC based code will not run on any Mac running OS 10.7. The following applications are no longer supported in Lion:
    • Fugu
    • Oracle Calendar
  • Samba is no longer used for connecting to or creating Windows shares. Apple replaced it with its own SMB/CIFS implementation called SMBX and is based on Microsoft's SMB2 protocol. Benefits of SMBX include the following:
    • DFS support: Macs with OS X Lion can now connect to DFS shares
    • Windows file sharing is faster and not as erratic as its Snow Leopard predecessor
  • Java is no longer bundled with OS X but is downloaded on demand from Apple similar to how Rosetta was installed on Snow Leopard.
    • Symantec Live update requires Java so SCS Computing Facilities will be installing Java on all SCS supported Macs.

What's New in Lion

  • A recovery partition is created when Lion is installed that gives the option to boot recovery tools such as disk utility or terminal. This also allows restores from a time machine backup or to reinstall the operating system.
  • A complete list of new features can be found here:
