TITAN 4 will not run on macOS 10.15 Catalina and later versions of macOS.
This is because macOS 10.15 removed support for 32bit applications. TITAN is dependent on a 32 bit component from a third party which is not compatible with macOS 10.15.
TITAN will continue to work on older versions of macOS as described below.
We are very keen to update TITAN, but that's currently out of our control.
If the situation changes, we will let TITAN users know.
PLEASE NOTE: if you are purchasing TITAN now, or want to continue to use it you will need to provide and maintain the following versions of software:
macOS 10.14 or earlier. (Note it is not possible to install macOS 10.14 on a computer which is supplied with 10.15)
iLok license manager 5.0.3
We reduced our support for TITAN in 2020 as nothing changed. This will not affect you if you are a prior user and you are able to maintain the above hardware and software components.
