It does work on mine. 10.15 as well, work in finder thumbnail as well as quicklook.

I managed to make it work by (EDIT: only the thumbnails):

• preview a webp file
• go to Security & Privacy settings
• allow the app (requires to unlock the configuration using admin privileges)

When I try to preview a webp file I get the “WebpQuickLook.qlgenerator” cannot be opened because the developer cannot be verified., how did you manage to make it work @Polaris-Dust ?

Have you tried xattr -d com.apple.quarantine ~/Library/QuickLook/WebpQuickLook.qlgenerator?

[schellenbergk]

thanks @parleer , worked like a charm!

[jerclarke]

Have you tried xattr -d com.apple.quarantine ~/Library/QuickLook/WebpQuickLook.qlgenerator

This worked for me too, but when you ask it as a question like that, my response is "why would I have tried that?"

Seems to me this problem affects 100% of new installations. If that command is the way to fix it, maybe it could be integrated into the brew solution, and listed on the readme for people installing the app?

@jerclarke, that's a great idea

Doesn't work for me. I tried two solutions (single and all users), but not good. What do I do wrong?

you can use:

sudo xattr -rd com.apple.quarantine ~/Library/QuickLook/WebpQuickLook.qlgenerator

Thank you @appdev – after a few failed attempts I finally got it to work for QuickLook. Unfortunately I don’t get thumbnails in Finder ... I tried to do what @Polaris-Dust suggested but don’t know which specific file/app I need to add where in the Privacy Settings ... can you please help me do that right? Thank you!
