Help: I Need Workaround for Photoshop old plug-ins not created for macOS 10.15 Not Working

I have an older plugin for sharpening from Pixel Genius, PhotoKit Sharpener. It is the best sharpening program out there but it is no longer supported by Pixel Genius. Their website gave a link to an Adobe page  that gave a terminal instruction to allow notorization of this plugin so it can run on Catalina or above. However when I used the terminal instruction I get a syntax error...see below. Any suggestions??

I tried using this terminal code to "notarize" an older plugin but I got a "syntas error: any suggestions

You may notice that I changed the reference folder for the plugin to 2022 for the latest version of photoshop

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>

 

sudo xattr -r -d com.apple.quarantine /Applications/Adobe\ Photoshop\ 2022/Plug-ins/<PhotoKit Sharpener 2.plugin>

-bash: syntax error near unexpected token `newline

Correct answer TheDigitalDog

The following instructions is still up on our site where you download the free installers.

 

Use Terminal and copy/paste this:
sudo xattr -dr com.apple.quarantine
Be sure to add a space after the e of ‘quarantine’
Then drag & drop the plug-in onto Terminal…the first plug-in requires you enter your password. The other plug-ins don’t.
Repeat the copy paste and drag & drop for each of the 7 plug-ins-even the oddball plug-ins like Toolbox & Previewer
You’ll have to quit and relaunch Photoshop…
This seems to allow the older PhotoKit Plug-ins to run like they used to on Mac. Pretty sure there’s no issue on Windows.

And if you do the above correctly, it does work without issue.

Thanks so much, you're a star! This is the main reason I didn't upgrade to Monterey until now. Too much stopped working.
