For users running macOS Catalina: tethering, updates, and other things you need to know

1. Capture One and macOS Catalina compatibility

2. Precautions for macOS updates

3. Tethering your supported camera on macOS Catalina

Capture One and macOS Catalina compatibility

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.

Capture One users who have upgraded to macOS 10.15.2 or 10.15.3 might experience some erratic behavior of the software, including tethering issues.

Precautions for macOS updates

When Apple releases a major update to its 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. 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.

Tethering on macOS Catalina

We released an update to Capture One 20 and Capture One 12 to fix the tethering issues which arose around the time of Mac OS 10.15.2 being launched.

Capture One 12.1.5 can be downloaded from your account on Capture One website in the Download section by scrolling down and selecting Download under Need the previous version?.

For a full overview of changes, please see the release notes.

Capture One 20.0.3 contains bug fixes, so it's highly recommended that you install the latest service release.

For a full overview of changes, please see the release notes.

When launching Capture One 12.1.5 or Capture One 20.0.1 (or later) for the first time on macOS Catalina, you will be presented with multiple requests for Capture One to access various different areas of your Mac.

In order to be able to shoot tethered to Capture One, you will need to accept these requests. These requests are dictated by the operating system and there is little we can do to circumvent these access/permission requests.

Below are the screenshots of how the messages will present themselves.

Press OK or Allow.

When you first connect your camera, you will be asked if Capture One is allowed to access to removable volumes. You will need to grant access to this as well if you wish to shoot tethered.

As the message states, you may need to restart Capture One at this point. We also recommend removing the cable from your Mac, starting Capture One and then connecting the camera again.

In instances where you may have rejected these requests or selected 'Don't Allow' - you can run the commands below in Terminal to reset the permissions, so that you are prompted to grant access again.

tccutil reset SystemPolicyRemovableVolumes com.phaseone.captureone13
tccutil reset Photos com.phaseone.captureone13

You will need to replace 'captureone13' with 'captureone12' if you're a Capture One 12 user in order for this to work.

If you are a Capture One 20 user, please do not edit the commands. 'captureone13' is the name of the Capture One 20 application.
