User permission issues

Lightroom CC 2015.5 or Lightroom 6.5 displays the error Lightroom encountered user permission issues on launch.

Lightroom encountered user permissions error dialog


Permissions issues may also result in crashes or hangs when you open any version of Lightroom, Photoshop, or Bridge.

Solution 1: Click Repair to Continue

In the error dialog box, click Repair to Continue.

Solution 2: Manually change folder permissions

Manually change the permissions on the following folders and on all the items in these folders to Read & Write, so that Adobe applications are able to write to these folders when opened or during use:

  • /Users/[user name]/Library/Preferences/
  • /Users/[user name]/Library/Application Support/Adobe/
  • /Users/[user name]/Library/Caches/Adobe/
  • /Users/[user name]/Documents/Adobe/

Do the following:

  1. Open the user Library folder. To do so, press Option and choose Go > Library in the Finder.


The user Library folder is hidden by default in Mac OS X 10.7 and later. To locate and access the user Library folder, refer to Can't see user library files on Mac OS X 10.7 and later.

  1. Change the permission on these folders and all items within these folders to Read & Write. To perform the permission changes, refer to the topics Assign permissions to users and groups and Apply permissions to all items in a folder or a disk in the Apple article Set permissions for items on your Mac.


Make sure that you apply Read & Write permission to all enclosed items within these folders. It requires your administrator name and password.  

  1. Try to launch Lightroom.

Solution 3: Use a script to restore permissions

If the previous solution does not resolve the folder permission issue, try this easy-to-run, shell-script-based solution explained below. This shell-script automatically restores the ownership and read/write permission, and it removes Access Control List (ACL) from the set of Adobe user folders and its subfolders.


To run the shell script, do the following:

  1. Download using the above link. By default, the file is downloaded to /Users/[user name]/Downloads/
  2. Unzip the downloaded zip file to extract the shell script file.
  3. On your Mac desktop, type Terminal in the Spotlight search box and launch the Terminal app.
  4. From the Finder, drag the unzipped shell-script file (from step 2) onto the Terminal window. You see the following text in the terminal window:
  5. Press Enter to run the shell script.
  6. When prompted, enter your Mac login credentials.
    Note: Ensure that you use the account with administrator privilege to log in.
  7. Try to launch Lightroom.

Solution 4: Set up a new admin user account

Set up a new admin user account and run Lightroom from that new account instead.
