As of November 2020, IS&T recommends waiting before upgrading to the newest Mac operating system, macOS 11 Big Sur. There are a number of applications in use at MIT that are either not compatible and/or may experience unexpected behavior when using Big Sur. A full list of the known issues using Big Sur with software at MIT can be found here.
SAP is reporting that all SAPgui for Java versions available today have issues running on macOS Big Sur because of various issues in the Java runtime. If the below steps do not work for you, please use Citrix on the VPN in the meantime.
Some MIT users may experience trouble connecting to SAPgui on Big Sur, and may encounter the following error message:
If you encounter this error message, a workaround is available. Please note, this workaround is not a guaranteed fix and during testing it did not resolve the problem for everyone impacted by the aforementioned error.
The advised workaround is to use the Terminal application in place of Ticket Viewer aka Kerberos Extras. Do not launch Kerberos Extras and generated a ticket. If you already have a ticket generated, destroy it and close the application.
Terminal is preinstalled on all Mac computers and can be found: Applications > Utilities --> Terminal.
After launching Terminal, enter the following command:
kinit username (username = kerberos username)
You will then be prompted for your kerberos password. Once you've completed this step, launch SAPgui and attempt to connect. Once again, this is a workaround that may work for some users, but a 100% success rate is not expected.
