Versions of PS and LRC for High Sierra 10.13.6

Latest Photoshop is version 24.4 released April, 2023.

https://helpx.adobe.com/photoshop/using/whats-new.html

Adobe expects all users to have the latest OS & apps, no more than 2 versions back.

Make sure your computer meets the minimum CPU & GPU requirements to support current versions. Most Creative Cloud apps work on:

• Windows 11 (64-bit), Windows 10 versions 22H2, 21H2, 21H1;
• MacOS 13 (Ventura), 12 (Monterey), or macOS 11 (Big Sur).

Hope that helps.

Okay, found this thread after posting:

However, think I am just going to stick to the verions I am using as they work.
