I am experimenting with writing a LR Classic plugin on macOS. I have been able to successfully install the samples, now I am going to install my simple plugin code. Whenever I do, I get a message like this
Could not read the metadata spec from this plug-in.
No script by the name m.lua
My code is sitting in a source directory under my user. When I move the entire .lrdevplugin folder to the Classic plugins folder /Users/paul/Library/Application Support/Adobe/Lightroom/Plugins, the plugin loads. This looks like a permission problem to me. What permissions does Classic need for the files as well as the intervening folders? Thanks!
