COD4 & macOS 10.15

MacOS Mojave is unfortunately the last version of macOS to support 32-bit applications: https://support.apple.com/en-gb/HT208436

Why is this important? While CSGO is unaffected, Call of Duty 4 is still built as a 32-bit application and may not function in the next release of macOS, expected summer 2019.

It seems the Aspyr is aware of this and working to release 32-bit versions of some of the favourites, though timelines are unclear for COD4 (if that will even be re-released as a 64-bit application):
