Known issues in Lightroom Classic
Check to see if the issue you're encountering is a known issue in the latest release of Lightroom Classic.
Get the latest camera support
The most commonly asked support question is "How do I get raw file support for the latest cameras?"
Install the latest Lightroom Classic updates
You can fix many problems by simply making sure that your Adobe software is up-to-date.
Adobe provides technical support and security fixes for the current version and the prior version. Bug fixes are only provided for the current version. See Lightroom Classic - Supported versions for complete details.
Install operating system updates
You can fix many problems by simply making sure your operating system is up-to-date.
- For macOS, see Get software updates for your Mac.
- For Windows, see Windows Service Pack and Update Center.
Adobe recommends that you perform your own testing on a non-production partition to ensure that brand-new operating systems work well with your current hardware and drivers.

Install graphics card (GPU) driver updates
To troubleshoot your computer's graphics card GPU (Graphics Processing Unit) and driver, see Troubleshoot graphics processor (GPU) and graphics driver issues | Lightroom Classic.
For more information on Lightroom Classic's utilization of your computer's graphics card GPU (Graphics Processing Unit), see Graphics processor (GPU) FAQ | Lightroom Classic.
You can avoid GPU driver crashes, screen/document redraw, blue or X’d-out images, or color display issues by using the latest video drivers. Updated drivers are available from the card manufacturer’s website (NVIDIA, AMD, or Intel).
Simply running Windows Update doesn’t ensure that you have the most recent video driver. Go directly to your card manufacturer's website to check for driver updates.
Your video drivers are included with your operating system updates. Make sure that you have installed all the latest OS updates by choosing Apple menu > About This Mac > Software Update.
Optimize Lightroom Classic’s performance
To optimize Lightroom Classic on your computer, see Optimize performance.
Calibrate your monitor
Corrupt monitor profiles affect both the performance and the color reproduction of Lightroom Classic.
Calibrate your monitor either by using your operating system’s calibration feature or a hardware colorimeter to create a good color profile for your monitor.
For more information on how to calibrate your monitor, see How (& Why) to Calibrate Your Monitor.
For answers to common questions asked about color in Lightroom Classic, see FAQ | Color in Lightroom.
You can solve many abnormal and intermittent behavior issues by resetting the Lightroom Classic preferences to their factory-fresh state.
To reset Lightroom Classic preferences:
- Quit Lightroom Classic.
- Start Lightroom Classic while holding the Shift + Option (macOS) or Shift + Alt keys (Windows).
A dialog box asks if you want to Reset Preferences.
- Click Yes.
For more details, see Recover catalog and images after resetting preferences.
Troubleshoot Missing Photos
When in the Develop module, Lightroom Classic indicates that the photo could not be found, or is offline, or missing, or your images display a missing icon () in image cells in the Grid view and the Filmstrip.
If you open Lightroom Classic and your catalog is empty or doesn't have all the images you're expecting, it's likely you've accidentally created a new catalog or opened the wrong or an old catalog. See
If you encounter the error 'The Lightroom catalog cannot be opened because another application already has it opened' when you launch Lightroom Classic.
Additional Catalog Resources:
To find quick answers to frequently asked questions about sync in Lightroom Classic, see Lightroom Classic sync FAQ.
If you have installed many third-party plug-ins and are experiencing odd behavior in Lightroom Classic, troubleshoot the plug-ins next.
- Check with the plug-in manufacturer to see if they have an update for your plug-in.
- Disable problematic plug-ins using Lightroom Classic's Plug-in Manager:
- In Lightroom, choose File > Plug-in Manager.
- Click Disable for each of the listed plug-ins.
- Check if the problem is still occurring.
- If the problem is resolved, turn the plug-ins back on one by one.
- Check to see if the problem reoccurs after re-enabling each plug-in.
Troubleshoot user account permissions
If none of the troubleshooting steps above solve your problem, your problem may be related to user permissions.
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.
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.
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.
To run the shell script, do the following:
- Download LightroomCorrectPermission.zip using the above link. By default, the file is downloaded to /Users/[user name]/Downloads/LightroomCorrectPermission.zip.
- Unzip the downloaded zip file to extract the LightroomCorrectPermission.sh shell script file.
- On your Mac desktop, type Terminal in the Spotlight search box and launch the Terminal app.
- 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:
- Press Enter to run the shell script.
- When prompted, enter your Mac login credentials.
Note: Ensure that you use the account with administrator privilege to log in.
- 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:
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.
If you encounter a user permission error when you launch Lightroom Classic, see Lightroom encountered user permission issues on launch for solutions.
After you create the admin user account, log in to the new user and run Lightroom Classic to see if the problem goes away.
Using the Repair Permissions command repairs permissions for the operating system, but not for applications, such as Lightroom Classic.
Start in safe mode to troubleshoot system add-ons and utilities
Sometimes, third-party extensions and other utilities can interfere with Lightroom Classic’s operation.
If you start your computer in safe mode, third-party extensions and utilities are turned off, which can help solve your problem.
- Starting up in safe mode: On macOS, safe mode disables all third-party extensions and startup items. It runs only required kernel extensions and Apple-installed startup items.
- Start your computer in safe mode: On Windows, safe mode starts Windows with a limited set of files and drivers.
