FAQs
ConQuest will not run on Mac OS X
Solution
On MacOS 11 (Big Sur), you need to upgrade to at least version 2020.3.1 as earlier releases will not work.
There is also a known bug where ConQuest 2020.3.1 will not work on Mac OS 10.14 (Mojave) - under these circumstances we recommend upgrading to MacOS 10.15 or 11.
