Does not seem to work for me under 10.13.6

[trych]

If I put the file under ~/Library/QuickLook, it still does not show me any .avif file preview. Tried a reboot, same thing. Is there any extra step I need to take?

[dreampiggy]

try to use

qlmanage -p -d test.avif

to show more information ?

It does not work for macOS 11.6. Here is the output of the command qlmanage -p test.avif:

Seems the old quicklook framework plugin does not works on the macOS 11 now....

Maybe I can release a new macOS 11 QuickLookUI extension to support macOS 11. Need to change some code.
