Preset Locations- help me understand the two different locations [Mac]

It's similar with Actions, there are two locations where they can be "officially" used. Saved .atn files can of course be saved and loaded from any location, however there is a reason that there are "official" locations for them.

Mac:
/Applications/Adobe Photoshop CC 2022/Presets⁩/Actions

Win:
C:\Program Files\Adobe\Adobe Photoshop 2022\Presets\Actions

By storing saved action .atn files in this default application/program location they will not be available to the built-in preset migration export tool (edit menu, presets, export/import presets).

For the built-in export/import presets feature to list saved actions for migration, they should be saved to a non-default location – the user level preset folder for actions:

Mac:

/Users/username/Library/Application Support/Adobe/Adobe Photoshop CC 2022/Presets⁩/Actions

Win:

C:\Users\username\appData\Roaming\Adobe\Adobe Photoshop 2022\Presets\Actions

I can only speak in terms of Windows systems, where the default location is where the .abr brush groups live.  If you right click inside the document widnow with the brush tool selected, that opens what I call the 'Right Click' panel. If you then click on the wee cog icon in the top right corner, the bottom of the list will show any groups you have in thew default location.

I have the beta version open at the moment, and have not got around to transferring my brush groups so the list is nearly empty.

I've used this opportunity to rectify that, so now have thos groups available.

When you create yopur own presets, it's important to add them to a New group folder.  Then open the main Brushes panel and Export Selected Brushes. this will create a new .abr file in the default Presets > Brushes file location.  If you don't dio this t=you will lose your new presets the next time you install a major PS update version.
