I'm using QGIS 2.18.20. On MacOS High Sierra 10.13.5 Only recently I haven't been able to find uninstalled plugins. The settings show the repository is "unavailable". I'm not using a proxy. I've tried using http:// instead of https:// but it comes up with SSL error.
I've manually downloaded the desired plugins (Animove and Point Sampling Tool) but I can't find the .qgis folder on my mac (perhaps this is a lack of knowledge about macs so please advise on this mac users!) so I'm not sure how to go about manually adding the unzipped files
