Hi there,

Sorry that you are getting an user permissions error while starting Lightroom Classic.

Would you mind checking the troubleshooting steps below? 

Click Repair to Continue

If you get the Lightroom encountered user permission issues dialog box on launch, click Repair to Continue in the error dialog box.

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.

Note:

The user Library folder is hidden by default in macOS 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.

2.   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.

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

3.    Launch Lightroom.        

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.

LightroomCorrectPermission.zip: Get file 

To run the shell script, do the following:

1. Download LightroomCorrectPermission.zip using the above link. By default, the file is downloaded to /Users/[user name]/Downloads/LightroomCorrectPermission.zip.
2. Unzip the downloaded zip file to extract the LightroomCorrectPermission.sh 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 LightroomCorrectPermission.sh shell-script file (from step 2) onto the Terminal window. You see the following text in the terminal window:
   /Users/[username]/Downloads/LightroomCorrectPermission.sh
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. Launch Lightroom.

Set up a new admin user account

Create an admin user account to identify permissions problems. For instructions on creating an admin user account, see the following: 

macOS:

• How to test an issue in another user account on your Mac

Note:

Be sure to change the New Account pop-up window from [Standard] to [Administrator] when creating the user.

If you still experience trouble on macOS, try repairing the permissions on the disk. For details, see Repair disk permissions with Disk Utility.

Note:

If you encounter a user permission error when you launch Lightroom Classic, see Lightroom encountered user permission issues on launch for solutions.

Windows:

• Create local administrator account | Windows

After you create the admin user account, log in to the new user and run Lightroom Classic to see if the problem goes away.

Let us know how it goes.

Thanks,

Akash
