Sattva Descreen plug-in for Adobe Photoshop

Compatibility Descreen plug-in with macOS Catalina (version 10.15)

Adobe states that Photoshop CC 2020 & Photoshop CC 2019 work with macOS 10.15 (Catalina) but have some known compatibility issues.

The Descreen plug-in is not yet fully compatible with macOS Catalina because the plug-in is not yet notarized by the Apple. When you launch Desreen the alert will appear:


As a temporary workaround you may remove the quarantine flag from the plug-in by using the Terminal following the instructions from Adobe:

Suppose you have installed Descreen Professional retail plug-in to the folder "/Applications/Adobe/Photoshop/2020/Plug-ins/".

1. In the Finder open Application > Utilities > Terminal.
2. Paste the command as one line (if your use Photoshop 2019, then change 2020 to 2019 in the command):

sudo xattr -r -d "/Applications/Adobe/Photoshop/2020/Plug-ins/Descreen Professional retail/Descreen.plugin"

press Enter.

3. You will be asked for your user password for unblocking computer to confirm the command. The password is not shown when you type it. Press Enter again.

This command will remove the quarantine flag from the plug-in.

If you see the message

xattr: No shuch file: ...

then check the path in the command and that you have installed the plug-in to this path.
You can determine whether or not a plug-in is quarantined by the command

ls -l@ "/Applications/Adobe/Photoshop/2020/Plug-ins/Descreen Professional retail/Descreen.plugin"

Which returns the result like this:

total 0
drwxr-xr-x@ 6 <username> wheel 192 Nov 24 15:11 Contents 22

The line with "" means that the plug-in is quarantined.
If the plugin is not quarantined, this line will be missing.

After removing the quarantine flag the plug-in should work as usual.
