I purchased the Instance Tool plugin on the UE4 marketplace - Instance Tool in Code Plugins - UE Marketplace
It installs fine on Windows, but when I select “Install to Engine” on my Mac, it prompts me for version, and then does nothing. It doesn’t download or install to engine, it just quietly takes me back to the launcher. I’m unable to open projects that use this plugin on my Mac. Copying the plugin file manually to the engine folder on the Mac works, but it’s less than an ideal solution, and not an option for those with a Mac-only workflow.
