How to uninstall Capture One 6, 7, 8, 9 and 10 on Mac OSX 10.7, 10.8, 10.9, 10.10, 10.11 and 10.12

Last updated: 20-04-2017


In order to completely uninstall Capture One 6.x, 7.x, 8.x, 9.x; 10.x, you will need to follow one additional step listed in the directions below.


1. Deactivate Capture One so that the activation will be free to use on another computer or on the same computer with new hardware. This can be done by navigating to Capture One>License... then click "Deactivate..."

2. Quit Capture One (if running)

3. Drag the Capture One application from your Applications folder to the trash: /Applications/Capture

4. Capture One 7/8/9/10 Backup the default Capture One Session or Catalog if you have work in it (/Users/Username/Pictures/), then delete the default session or catalog.

Capture One 5/6: Delete the "Col" file located here: /Users/Username/Pictures/Capture One Library/Capture One.col (Capture One.col50 with version 6)

Accessing the User Library folder, in 2 ways:

5a. Go to the User Library folder from Finder by selecting: Go > Go to Folder...
You can then enter the folder destination "~/Library"

5b. Or you can go to the drop down "Go" in the finder menu next to the Apple. Select the Go drop down and press the Shiftkey when the drop down is scrolled down - now an extra line "Library" will appear. Access this and you will be directed to the hidden Library folder. See screengrab below. NOTE: On OS X 10.11.x, the shortcut key is Alt/Option rather than Shift.


6. Capture One 7: Delete the Preference files located here*: 
/User/Library/Preferences/com.phaseone.captureone.plist and/or .captureone7.plist

/User/Library/Preferences/com.phaseone.captureone.LSSharedFileList and/or com.phaseone.captureone7.LSSharedFileList

*Capture One 8 users should use the method described below. 

NOTE: Mavericks/Yosemite: uninstall step for Capture One 7/8 prefs:

On OS X 10.9 (Mavericks) and later there is a daemon running in the background (that maintains a cache of all these plist files) called “cfprefsd”. Deleting a plist file from Finder (as mentioned prior in 10.7 and 10.8) doesn’t work in 10.9 because this service will restore it from cache when the file is needed. Do NOT delete the file from Finder. Instead run these commands in the Terminal and hit return after each line. Capture One must be closed when you do this and you must wait several seconds for the command to take effect. You can access terminal via Spotlight search or manually, at /Applications/Utilities/

Please ignore any comments below in (italics) These should not be typed in Terminal. The commands are case sensitive.

(To delete main plist type the following:)

defaults delete com.phaseone.captureone7

defaults delete com.phaseone.captureone8

defaults delete com.phaseone.captureone9

defaults delete com.phaseone.captureone10

(Then delete the session history preference in the same manner:)

defaults delete com.phaseone.captureone7.LSSharedFileList

defaults delete com.phaseone.captureone8.LSSharedFileList

defaults delete com.phaseone.captureone9.LSSharedFileList

defaults delete com.phaseone.captureone10.LSSharedFileList


7. Delete the Application Support folders. If you plan to reinstall Capture One, only delete the Batch Queue folder within the Capture One directory (below). If you do not plan to reinstall Capture One delete the entire Capture One directory. 

/User/Library/Application Support/Capture One/Batch Queue
