A recent macOS update for systems running Mojave 10.14 is causing problems with connections to University resources. Users will not be able to connect to shared network volumes or print. If the screen lock engages, the user will not be able to log back into their account. Other versions of macOS are not known to be affected. ITS staff are currently working with Apple to resolve the situation.
Temporary workarounds: restart the computer every two hours and turn off screen lock.
