Uninstalling Capture One on a mac

November 20, 2008 | Atlanta, Tips & Tech Support

Update: This article applies equally well to uinstalling Capture One 4 or Capture One 5.

We have received a few requests on how to do a clean uninstall on Capture One 4 or Capture One 5 on a Mac.  Currently, when upgrading to a newer Capture One software, it is recommended that you do a clean uninstall and then install the latest Capture One version. Check out Phase One’s Knowledge Base Article 1164 that will show you exactly how to properly execute it.

Update: If you’re a Windows user you can follow this link for Phase One KB Article 1158 on uninstalling on Windows.

Note: Please note that if you are only using Capture One with Phase One digital backs that you do not need to “deactivate” or otherwise deal with licenses or activation. Unlike Capture One 3 DB, Capture One 4 does not need an license key, activation, or registration for use in “digital back only mode”

Note: If you are doing this as part of “reinstalling” – in other words if you plan on using the software on this computer again immediately - then there is no need to follow the “deactivate” step.

Note: This applies to any version of Capture One 4.X or Capture One 5.X.

Capture Integration’s Further Recommendations

The following two recommendations are rarely required to restore Capture One to full-and-normal operations.

Delete User/Library/Application Support/Capture One/

Delete Proxys and Focus Mask Files

1) In the Finder Select File-Find

2) Push the plus button to add a search critera

3) Search for Name – Ends With – “.cop” (later you can search for .cof which corresponds to focus mask files in capture one 5 and after)

4) Double and then triple check that you are searching only for files ending with .cop. If you’re not 100% sure all listed files are .cop files then stop and do nothing

5) Select All and Delete

You may also wish to delete the entire folder “Capture One Library” rather than just the .col45 or .col50 file. Before doing this, make sure no important raw or processed files are in the “captures”, “trash” and “output” folders therein. Don’t blame us if you delete raw files!

Summary: If you have already done this process and read and understand the above article here is a summary of the files involved for the Mac:
