Doesn't work on macOS Catalina

[ernestp]

subj macOS 10.15

[AdamSGit]

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

[Polaris-Dust]

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)

[schellenbergk]

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 ?

[parleer]

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?

[schellenbergk]

@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!

Thank you for the alternative.
sudo xattr -rd com.apple.quarantine ~/Library/QuickLook/WebpQuickLook.qlgenerator
This solution started working for some reason.

[fharper]

It worked for me only if I install it from the App Store. Thanks @doitauto !

[bissy]

It worked for me!
After installing with terminal.app, works only QuickLook (not Thumbnail),
but After restart Mac, It works!
Thank you!

[AddictArts]

@fharper @doitauto How do you load from App Store or install from the App Store? This qlgenerator is not in the App Store. Thanks

oh, I didn't realize but I install another app with the same name, sorry for the confusion.

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

did not work for me... I keep getting: "No such xattr: com.apple.quarantine"

[Metacomet10]

I installed it via Homebrew, ran this
xattr -rd com.apple.quarantine ~/Library/QuickLook/WebpQuickLook.qlgenerator
and it works!
Catalina 10.15.7

I think you need to allow full harddisk access for your terminal application.

I am also unable to get this to work on my iMac

qlmanage -p /Users/custa/git-projects/sofa/images/cdn-sports/netball/11391/801/999806-headshot.webp
Testing Quick Look preview with files:

is what I get when I try to quicklook it from the command line. When I try just using space for quicklook I do not get a preview, and the icons are generic image icons. I have trie all the suggestion above in this thread but am still not getting it to work.

I am on Catalina 10.15.7

Just found out about this fix and can confirm it still works on MacOS Catalina 10.15.7 and Safari 15.6.1.

I used this command to install it:
curl -L https://raw.github.com/emin/WebPQuickLook/master/install.sh | sh

No reboot required. Works well with Google WEBP example images.
