While there are a handful of free Photoshop alternatives, the open source program GIMP comes closest to Photoshop’s advanced tools. As an open source program, GIMP is free to download for Mac, Windows and Linux. GIMP, which stands for GNU Image Manipulation Program, has several of the same tools as Photoshop.

Adobe has discovered the compatibility issues listed below with running Photoshop CC 2018 (and earlier) with macOS 10.14 Mojave.

Adobe strongly recommends that customers update to the Photoshop 2019 release prior to updating to macOS 10.14 Mojave. Older versions of Photoshop 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.

Dark Appearance setting doesn't affect all of the User Interface

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:

1. Go to Preferences > Interface.
2. 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.

Save For Web settings are not retained between sessions

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.
