Seems macOS 10.15 Gatekeeper rejects QuickLook plugins which render HTML.

So far, when you can disable Gatekeeper as following command at once, the plugin will work.

$ sudo spctl --master-disable

(You can also enable GateKeeper as following)

$ sudo spctl --master-enable
$ spctl --status

without gatekeeper also does not work. I tried every way. Other plugins which render HTML are working with gatekeeper. ( qlmarkdown, SourceCodeSyntaxHighlight )

It worked for me like this:

1. Install the plugin
2. Reset Quick Look: qlmanage -r
3. Open a Finder window and attempt to Quick Look a markdown file
4. Close the Finder window
5. Open Preferences > Security & Privacy and click "Allow Anyway"
6. Quit Preferences
7. Remove the quarantine attributes: xattr -d -r com.apple.quarantine ~/Library/QuickLook/
8. Reset Quick Look: qlmanage -r

1. Download the release
2. Remove the quarantine flag

xattr -rd ~/Downloads/QLMarkdownGFM.qlgenerator.zip

3. Install

However, I no longer use this. On Catalina I replaced all QL plugins with Glance, but that stopped working on Big Sur and the project on github was archived, so I switched to iPreview.

Removing the quarantine flag does work and allows you to successfully install it in Catalina (It worked successfully for me without changing or disabling Gatekeeper, although a reboot may be necessary if qlmanage -r does not work). However, I have not tested this in Big Sur and the problem may be due to a lack of codesigning all included libraries used in the QL plugin.
