installationqgisqgis-3qgis-plugins
I just installed QGIS 3.4 on my computer (macOS Sierra 10.12.6) and I'm trying to install QuickMapServices, but I'm unable to. My plugins window looks like this:
and the settings tab says "The settings on this tab are only applicable for Python Plugins. No Python support detected, thus no settings available":
I downloaded QuickMapServices from the QGIS Python Plugin Repository, but I can't access it. I have Python 3.6.0 on my computer.
I am not sure i can solve your problem. But there has been problems fetching python plugins while behind a proxy. In your case, it seems only the dafault plugins are visible(displayed as "locally available").
If you check the repositories tab, everything will be shown as Unavailable(check "Status" field) as in the picture below.
you can get the repo address by copying the urls from the picture above.
From there you can download your plugin and copy it to your python plugins folder. QGIS will then show your copied plugins in the plugins list.
Edit This could be a solution. It worked for me behind a proxy. In Qgis, Select Settings>Options.
Adjust Network as shown in below image.

There are two places where python plugins can be found:
C:\OSGEO4W\apps\qgis\python\plugins or C:\Programs\QGIS Brighton\apps\qgis\python\plugins)C:\users\username\.qgis2\python\pluginsThe first place is only for core plugins like fTools and GdalTools, while the contributed go into the second one. The folder .qgis2 might be hidden by the operating system. Make sure you preserve the folder order. The plugin has to be in a folder with its name, and in that folder there has to be an __init__.py and metadata.txt files. It might be that your zip programme creates another subfolder, which can not be used by the plugin manager.

Update your Mac OS to High Sierra 10.13 or higher. This worked for me.
