Operations computers are managed by the IT Workstation Support Group under the Operations Desktop Support (ODS) program. At this time Operations Mac users cannot install the latest macOS, Mojave. We are currently blocking this macOS until we can confirm that all standard ODS software is compatible with the upgrade. Test results indicate that all software works except for Spirion, a Personal Identifying Information (PII) removal tool. We are waiting on the vendor to release an update. Delivery date not yet published. Once a Spirion update is provided, ODS Mac users will be able to download and install Mojave.
For non-Operations users, always approach major operating system upgrades with caution. Users should always verify:
Hardware compatibility
Application compatibility
Backup capability
RoaringApps (https://roaringapps.com/), a crowd sourcing website provides information on application compatibility with operating system versions. All Mac users should ensure they have a backup of their system before doing any kind of update to minimize downtime if the upgrade fails.
