IS&T strongly recommends Mac users wait to install Mac OS X 10.7 (Lion)

This recommendation is based on Mac OS X 10.7's incompatibility with key MIT applications, including McAfee Security Suite, SAPgui, Fetch and Kerberos authentication.
On June 6 at its Worldwide Developers Conference, Apple announced that its next operating system — Mac OS X 10.7 (Lion) — would be available to the general public sometime in July.

For the past several months, IS&T has been testing pre-release builds of Lion against MIT's core services and systems. During this time, several incompatibilities have been found with key MIT applications, including McAfee Security Suite, SAPgui and Fetch. The new version of Mac OS X also breaks the authentication mechanism used by our Kerberos servers.

For these reasons, IS&T strongly recommends that all users wait to upgrade existing hardware to Mac OS X 10.7 (Lion).

IS&T will continue to work with Apple and third-party vendors to resolve outstanding issues with Lion and will inform the MIT community as solutions and workarounds become available.
