Earlier today, Apple released its newest operating system for the Mac, OS X 10.8 (Mountain Lion).
Based on preliminary testing of prerelease versions, Information Services and Technology (IS&T) recommends that Mac users wait to upgrade and continue to use Mac OS X 10.6 or 10.7 while IS&T completes its review and testing of OS X 10.8.
As with any new operating system release, there are some incompatibilities, bugs, and an associated learning curve. Also, some applications that are important or critical to productive, safe computing at MIT do not yet support 10.8. For more information, and a list of known issues and workarounds, visit the OS X 10.8 Project Wiki (certificates required).
Based on past releases, IS&T expects that Apple and third-party software vendors will release several updates addressing these incompatibilities and, in the coming months, will officially certify that their software supports 10.8.
The IS&T Computing Help Desk is offering limited support for 10.8. This includes getting connected to the MIT network and addressing basic configuration issues for early adopters and for new machines arriving with 10.8 pre-installed. As critical application issues are resolved, more in-depth support will become available.
Limited MIT documentation for 10.8 can be found in the Knowledge Base. This page will be updated frequently as testing is completed for applications and features commonly used at MIT.
IS&T will have a limited number of OS X 10.8 licenses available for MIT faculty and staff. We are working with Apple to acquire these licenses and will share more details as they become available.
Additionally, note that before upgrading on their own, departmental users should first check with their local IT support regarding the roll-out plan of any new operating system.
