Capture One 12.1.4 is the first release to support macOS 10.15 Catalina. It has been tested and is supported up to macOS 10.15.1.
On December 10, 2019, macOS 10.15.2 became available. Please note that macOS 15.2.1 is the latest supported version for Capture One 20 for now. Capture One 20 users who have upgraded to macOS 10.15.2 might experience some erratic behavior of the software, including tethering issues.
When Apple releases a major update to their operating system, e.g. macOS 10.15 (Catalina), it can be very tempting to download and install these updates right away.
We strongly advise against this for several reasons:
- The OS itself can contain bugs which can hinder your workflow drastically
- This also applies to any hardware/cameras you may be using with Capture One. For instance, with Mac OS 10.11 (El Capitan) tethering was completely broken by the new OS
You may find that the application runs on an unsupported operating system, but we cannot guarantee this, due to it being untested. If you must have the latest version of macOS Catalina installed, test your workflow end-to-end before putting it into a mission-critical production environment.
