Information Security Office Compliance


https://security.utexas.edu/content/min-security-standards | Systems > Minimum Standards > 4.5. System Hardening > 4.5.2

  • "Operating system and application services security patches are installed expediently (e.g., 30-days) and in a manner consistent with change management procedures. Products that no longer receive security updates from the vendor (e.g., unsupported) are not authorized."

  • Apple does not provide security updates for anything later then the last three operating systems released. At this time, you need to be running at least macOS Mojave 10.14.6 (this is likely to change Fall 2021) to be in compliance with the Information Security Office's minimum security standards.

Know Before You Upgrade / Known Issues

Starting with macOS Catalina 10.15, 32-bit apps are no longer compatible with macOS.

https://support.apple.com/en-us/HT208436

How to find and view all 32-Bit apps on a Mac:

  1. Hold down the option/Alt key on your keyboard, then select the  Apple menu
  2. Choose “System Information...” from the top of the Apple menu list
  3. In the System Information app, scroll down on the left-side menu and choose 'Applications' under 'Software'
  4. Look for the '64-bit (Intel)' option in the column header in the top box on the right, and click the title to sort the column by 64-bit
  5. Every app that says “No” is 32-bit, every app that says “Yes” is 64-bit


***Most software developers have updated their apps to 64-bit, but if you have special software you use and need to make sure it works on an up-to-date operating system, please confirm compatibility with the developer.***

Box Drive is not currently supported on Apple's M1 chip.
