Focus Point Plug In

"I contacted the app developer 6 days ago and have not heard a thing, oh well"

The plugin hasn't been updated in 2.5 years.

You could probably fix this bug yourself, with a small amount of effort, by updating the "mogrify" utility to the latest version. I haven't tested this, so there may be gotchas:

1. Install Mac Ports: https://www.macports.org/install.php

2. In Terminal, do this command:

sudo port install imagemagick

3. In Terminal, do this command:

cp `which mogrify` FocusPoints.lrplugin/bin/imMac/mogrify

I confirmed that the Show Focus Points plugin uses a third-party utility "mogrify" that is 32-bit:

$ file FocusPoints.lrplugin/bin/imMac/mogrify 
FocusPoints.lrplugin/bin/imMac/mogrify: Mach-O universal binary with 1 architecture: [i386:Mach-O executable i386]
FocusPoints.lrplugin/bin/imMac/mogrify (for architecture i386):	Mach-O executable i386

 32-bit programs aren't supported by Mac OS 10.15 (Catalina), so you'll definitely have to contact the plugin developer for a new version with a 64-bit version of "mogrify".

(Older programs with 32-bit addressing can use only the first 2^32 = 4 billion bytes of memory. Newer programs have 64-bit addressing and can use much, much more memory -- 2^64 = 10^19 bytes.  Prior to Mac OS 10.15, you could run both 32- and 64-bit programs on Mac OS. But with 10.15, you can only run 64-bit programs.  This isn't a security restriction per se but rather Apple deciding to save engineering costs by phasing out older technology.)

You should definitely contact the plug-in author, because the tighter security restrictions in macOS 10.15 Catalina have interfered with or blocked some plug-ins for other Mac software, for example, Photoshop. If that is the problem with this Lightroom plug-in, the developer might need to release a version that has been properly "notarized" for Catalina.

In addition to the suggestion by Johan, it would likley be more beneficial to contact the plugin in vendor.

This plugin could be partially 32 bits, which means it can't run on MacOS Catalina.
