Which Photoshop versions are compatible with macOS Catalina?

Photoshop 20.0.6 and later versions work with macOS 10.15 (Catalina) but have these known compatibility issues. You may want to remain on your current version of macOS until these issues have been resolved.

Adobe strongly recommends 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, and so forth). 

If you do encounter issues not already documented here, feel free to report them on our feedback site.

Are legacy or perpetual versions of Photoshop compatible with macOS Catalina?

No, legacy/perpetual versions of Photoshop were not designed or tested to work on macOS 10.15 (Catalina). They are not supported in any way for use on macOS Catalina.

Adobe does not recommend that customers using old versions of Photoshop upgrade to macOS Catalina.

Incompatible versions (version 19.x and earlier) will not display in the ‘Older Versions’ list within the Creative Cloud desktop app.

Older versions use 32-bit licensing components and installers. Therefore, they cannot be installed and activated after upgrading to macOS Catalina. Upgrading to macOS Catalina with an older version already installed on your computer may allow the application to function in some capacity; however, you will not be able to reinstall or activate the application after the macOS upgrade.

Before upgrading to macOS Catalina, you may uninstall the older versions as the uninstaller will not work after upgrading. If you have already upgraded to macOS Catalina, you can use the Creative Cloud Cleaner Tool to uninstall older versions.

Known compatibility issues

Adobe has discovered the compatibility issues listed below with running Photoshop 20.0.6 with macOS 10.15 (Catalina).

File naming options don't work correctly in the Save As dialog

Save As dialog

Issue 1

Changing the file format does not change the extension of the file in the name field.

Workaround

Edit the name’s extension manually to match the format.

Note:

Photoshop will not be able to open a file if the extension does not match the file format, resulting in the following errors:

If a file was already saved with a mismatched extension, the file can be renamed with the correct extension and will open in Photoshop.

If you cannot remember the actual file type the file should be, see Determine the file type of a document.

 

 

Issue 2

Checking "As a copy" does not append “copy” to the file name.

Workaround

Manually edit the name and add “copy”, or change the name to something unique.

Note: We are working with Apple to address this issue.

Plug-ins not found or cannot be verified

New to mac 10.15 (Catalina) is that plug-ins that are quarantined will return a Photoshop error that "the file was not found" or an OS error that says that the plug-in "can't be opened because its integrity cannot be verified.

Plug-In Error dialogs

This happens with plug-ins that are not notarized that are downloaded from the web or installed by other methods such as drag & drop.

Customers that have plug-ins already installed and then update to macOS 10.15 should not see this issue.

Customers that upgrade to macOS 10.15 and then try to download and install a plug-in may see failures.

Note:

Plug-ins will appear as having loaded successfully when you look at Help < System Info. This is because at launch time we only gather basic information about the plug-in such as the its name. The quarantine check does not happen until a customer tries to use the plug-in, often in the form of a 3rd party filter, or saving a file using an optional/3rd party file format plug-in.

Solution

Obtain updated plug-ins from 3rd party developers that are notarized for macOS 10.15. Photoshop will load plug-ins that have been notarized by Apple.

 

Workaround

For older plug-ins that are not notarized, customers with Admin user privileges can remove the quarantine flag by using the following command if the plug-in is installed in the Photoshop application plug-ins folder:

sudo xattr -r -d com.apple.quarantine /Applications/Adobe\ Photoshop\ 2019/Plug-ins/<plug-in-name>

Or, use the following command if the plug-in is installed in the shared Creative Cloud plug-ins folder:

sudo xattr -r -d com.apple.quarantine /Library/Application\ Support/Adobe/Plug-Ins/CC/<plug-in-name>

 

Determining whether a plug-in is quarantined

Customers can determine whether or not a plug-in is quarantined by using the Terminal.

Example if plug-in is in the Photoshop application plug-ins folder:

% ls -l@ /Applications/Adobe\ Photoshop\ 2019/Plug-ins/<plug-in-name>/

Example if plug-in is in the shared Creative Cloud location folder:

% ls -l@ /Library/Application\ Support/Adobe/Plug-Ins/CC/<plug-in-name>/

 Note: replace <plug-in-name> with the actual name of the plug-in you need to correct

Which returns the following result:

total 0
drwxr-xr-x@ 6 <username> wheel 192 Sep 26 15:11 Contents
com.apple.quarantine 22 

"com.apple.quarantine 22" means that the plug-in is quarantined.

Note: See Locate Plug-In Folders for help finding the locations of plug-ins.
