Adobe has discovered the compatibility issues listed below with running Photoshop 2018 (and earlier) with macOS 10.14 Mojave.
Adobe strongly recommends that customers update to the Photoshop CC 2019 release prior to updating to macOS 10.14 Mojave. Older versions of Photoshop CC were not designed, nor extensively tested to run on macOS Mojave. Additionally, we strongly recommend that customers do their own testing on a non-production partition to ensure that new operating systems work with their current hardware and drivers (printing, etc). You may wish to remain on an older version of the OS that is compatible with prior versions of our software.
If you do encounter issues not already documented, feel free to report them on our feedback site.
Adobe has discovered the compatibility issue listed below when running Photoshop CC 2018 and earlier releases on macOS 10.14 Mojave.
Install Photoshop CC 2019.
Workaround (Earlier versions)
If you launch Photoshop 2018 (and earlier) after updating to macOS 10.14, you will be presented with the following dialog:
Adobe Photoshop would like to control this computer using accessibility features. Grant access to this application in Security & Privacy preferences, located in System Preferences.
If you click Deny, you observe the following problems when using Photoshop:
- Pen pressure does not work
- The Busy cursor displays while painting
Instead, follow the steps below:
After you use the Liquify filter on an image on a specific Mac hardware/graphics cards, there are unexpected black pixels on the image.
Macs with the following graphics cards are affected:
- AMD FirePro D300 2048MB
- AMD Radeon HD - FirePro D500
- AMD Radeon R9 M370X 2048 MB
Update your macOS to 10.14.1
When you enable Dark Mode appearance in the macOS System Preferences > General dialog, not all of Photoshop's UI changes to reflect the Dark setting. The Application menus inherit the Dark Mode setting but the following elements do not:
- The application frame and panels
- Photoshop dialogs
- Pop-up menus
- Panel Menus
- Context Menus
- OS dialogs, such as Open... and the Apple Color Picker
Photoshop has its own settings for controlling the application frame, panels and Photoshop dialogs. To have these user interface elements better match the Dark Mode appearance:
- Go to Preferences > Interface.
- Set the Color Theme to the darkest setting.
Note: Pop-up, panel and context menus, as well as OS dialogs, such as Open and the Apple Color Picker, are unaffected by this setting.
When you click on the Share icon in the far right of the Options bar to share an image, Facebook, Twitter, etc are no longer an option in the menu.
Photoshop uses the macOS APIs for sharing and these options have been removed in Mojave.
When you quit and relaunch Photoshop, your last used settings in Save For Web are not preserved. Adobe's engineering team is investigating this issue.
If you've used a terminal command to enable only Dark Menu Bar and Dock in Mojave, this setting can cause Photoshop and other applications to crash. Follow the instructions to revert to Full Mojave Dark Mode on the same page.
