Disconnect external devices

An incompatible or malfunctioning external device can sometimes cause issues with Photomator. To test external devices:

  1. Quit Photomator, then choose Shut Down from Apple menu .

  2. Disconnect all external devices other than the keyboard and mouse.

  3. For Intel-based Mac computers only, reset NVRAM. You only need to do this the first time you disconnect external devices.

  4. Turn on your Mac.

If the issue only occurs when a particular device is connected, you may need to update or service the device. Contact the manufacturer for support.

Check system requirements

Photomator requires macOS Ventura 13 or later. To determine which version of macOS you have:

  1. Choose About this Mac from Apple menu .

  2. Find your version of macOS next to macOS in the list.

If you have an unsupported version of macOS, check that any third-party software installed on your Mac is compatible with the latest version of macOS, then update your macOS.

Update Photomator

Before you update, try to complete all active projects, back up your app, and turn off automatic updates. Find out how to back up your app and update Photomator and other Pro Apps.

Check that Photomator can access your photo library

Check the Privacy & Security settings on your Mac to make sure the app can access your photo library:

  1. Choose System Settings from Apple menu .

  2. Click Privacy & Security in the sidebar.

  3. Click Photos, then make sure Photomator is turned on.

If your Privacy & Security settings on your Mac are set correctly and you still can’t see your photo library in the Photos Browser in Photomator, you may have a different photo library designated as the System Photo Library.

Check your System Photo Library

Photomator can only access the library designated as the System Photo Library, so you may have designate the library that you want to use with Photomator as the System Photo Library.

Make sure photos and images are stored on a supported device

You can’t store your photos library on a storage device used for Time Machine backups. And to avoid possible data loss, don’t store your photo libraries on removable storage devices such as SD cards or USB flash drives or on a device shared over a network or the internet, including cloud-based storage services.

If you store your photo libraries on external storage devices such as SSD drives, make sure the devices are formatted with the APFS format. Older external storage devices can also be formatted as MacOS Extended.

If you want to store your photo library on a supported type of external storage device, find out how to move it.

If you buy an external drive that's pre-formatted with a Windows file system such as MS-DOS (FAT32), ExFAT or NTFS, reformat the drive as APFS.

Check media compatibility

Photomator supports all the most popular image formats, such as HEIF, JPEG, PNG, TIFF, WebP and macOS-supported RAW formats. Check your media's format to make sure it's compatible with Photomator:

  1. In Photomator, select the file in the Photos Browser, then press Command-I.

  2. Note the format of the image.

If you’re using an unsupported file format, retake the image in a supported format. You can still edit and export the image in Standard Dynamic Range (SDR).

Check third-party software compatibility

Note all the third-party software you're using with your Mac, which can include other image editing apps, utilities, and security, antivirus and malware software. Contact the developers to make sure their products are compatible with the versions of Photomator and macOS that you have installed.

Check camera or storage device firmware

For any external devices you're using such as cameras or storage devices, check with the manufacturer for software or firmware updates. Follow the manufacturer's instructions to update.

Test in a new user account

Create another administrator user account on your Mac, then try to recreate the issue in the new account. If the issue doesn’t occur in the new account, settings or files in the original account may be causing the issue.

Test with a new image

  1. Create test media for Photomator:

    • To take a screenshot, press and then release these three keys together: Shift, Command and 3. The screenshot is saved to the Desktop.

    • In Photomator, choose File > Import, locate and select the screenshot file, then click Import.

  2. Try to reproduce your issue using test media.

If you can't reproduce the issue using your test media, the issue might be related to the source file you're using. Try to get a new copy of the source file.

  2. Locate Photomator and drag it to the Bin.

Test Photomator in a new volume on your Mac

As a final check to make sure Photomator, macOS and your Mac are working as expected, create a new volume on your Mac, install macOS and Photomator on the new volume, then test with test media.

  1. Install macOS on a new volume of your built-in startup disk. Make sure it’s the same version of macOS you’re currently using.

  2. When macOS installation is complete, set up the Mac, then set the default startup disk to the new test volume.

  3. Shut down your Mac and disconnect all devices, except for a keyboard and mouse or trackpad.

  4. Turn on your Mac.

  5. Select the primary volume in the Finder, then press Command-E to unmount the primary volume. This will leave only the test volume mounted.

  6. Download and install Photomator from the Mac App Store. Make sure you sign in to the App Store with the Apple Account used to originally purchase Photomator.

  7. Create test media for Photomator:

    • To take a screenshot, press and then release these three keys together: Shift, Command and 3. The screenshot is saved to the Desktop.

    • In Photomator, choose File > Import, locate and select the screenshot file, then click Import.

  8. Try to recreate the issue in Photomator in the new volume. If the issue doesn't occur, then Photomator, macOS and your Mac are working as expected. Your issue is most likely caused by the images you're working with, external devices or other third-party products such as plug-ins.

  9. Shut down your Mac, then follow the directions to change your startup disk, making sure you've chosen your primary volume (called Macintosh HD by default) as the startup disk.

  10. In your primary volume, double-check third-party hardware and software compatibility and make sure you've updated macOS to the latest version.

  11. When you've finished testing, use Disk Utility to delete the test volume.
