When I go to Manage Plugins, I can see only grayed-out items. When I try to install a new plugin, I get an error "Could not install plugin. Error code -20". Re-installing Cretive Cloud did not help. This happens on a Mac Powerbook, Intel-based. On my Windows system it works fine. Help needed how to resolve this.

Oops missed that bit 😁 still I think it's more of a Creative Cloud app issue rather than Photoshop
@Ged_Traynor, i think you are correct. this person is having a problem with their cc app.
that error code is a path issue with the plugin installer.
@stefan.g, are you trying to install "easy panel"?
and, no matter which plugin you're trying, if signing out/in (per @Ged_Traynor) doesn't help, reset the cc desktop app:
make sure it's in the foreground, then press:
Win: Ctrl + Alt + R
Mac: Cmd + Opt + R
if that fails, restart your computer and retry installing.

Neither of these helped - signing out/in, restart computer, reinstalling cc and ps, reseting the cc desktop app.
again, what plugin are you trying to install?
Easy Panel, but the problem is the same with ny other plugin I try to install from CC->Stock&Marketplace.
assuming your have win 8 or better, or mac 10.8 or better:
your default browser must support tls 1.2, https://helpx.adobe.com/x-productkb/multi/eol-tls-support.html
to test your default browser's tls you can use , https://clienttest.ssllabs.com:8443/ssltest/viewMyClient.html
Yes, my browser supports TLS 1.2 and 1.3. I suspect it could be some path/directory permission or not available issue, but I do not know which path it is supposed to access for the plugins.
The problem was resolved by a clean reinstall of Mac OS and then CC and PS. Reisntalling just CC/PS was not sufficient.
