For upgrade from 10.13 or earlier, please see http://go/mojave/ as well for noteworthy changes introduced before Catalina.
Current Known Issues & Areas of Concern
- 32-bit applications will no longer be supported as of Catalina. Launching these applications has resulted in a warning message within High Sierra and Mojave. (Most common applications in use at Middlebury have been 64-bit for years.)
- For Terminal users, the default shell is "zsh", rather than "bash". Bash is still available.
- KaleidaGraph is currently still a 32-bit application and will not run under Mac OS 10.15. A 64-bit version is under development, although it will not be released before Catalina and we do not have a release date at this time. KaleidaGraph will still run under Mojave (10.14) and earlier versions of the OS.

2018 and older versions contain 32-bit applications. See here or consider complete removal and fresh installation of 2019 only - see here.
