UpgradeOSX

Should I upgrade OS X? How?

Do not upgrade OS X without a consultant's approval. Note than an update is different from an upgrade. If Software Update asks you to download a new verion of OS X, and that version has a new name, consider it an upgrade.

Do not install versions of OS X with new names during the cohort.

Updates are ok.

Once you're given the go-ahead from a consultant, you should perform the upgrade outside of work hours. When it's finished, things will break. Typically, you'll only need to follow a few steps to get back in working order.
