OIT recommends waiting on new Mac OS - High Sierra

OIT staff have been testing the beta version of the new Mac OS [High Sierra] which should be available in a few days. At this time we do not recommend upgrading. It has been our experience that new releases of an OS require fixes or updates that are normally addressed within the first 30 to 60 days of the release.
We will do more extensive testing when the full release is available. If you’d like to know when we are confident in the upgrade please ask us to notify you by emailing desktop@williams.edu or calling 413-597-4090.
