Doesn't work on macOS Mojave

[wottpal]

Hey,
I tried to install this extension (both ways), restarted my machine and it doesn't work at all (no thumbs, no quicklook). I tried on two machines running on Mojave - works on none of them :(

Would be great if you provide some help!

Regards from Germany

Same here 😢

@wottpal @umlearn have you updated to the latest Mojave? It does work on my 10.14.1.

[umlearn]

@grikomsn Yes, I'm running 10.14.1. Can't figure it out why it doesn't work for me.

[grikomsn]

Possible reasons:

• Corrupted or different .webp file: try convert any image using Squoosh (repository) and view it using Finder
• Current user can't use the plugin: try install the plugin system-wide using the second command (install-all.sh) (I installed using this command)

[grikomsn]

@wottpal, @umlearn, any progress?

[wottpal]

Hey @grikomsn,
sorry for the late response.

I've tried multiple legit .webp files (also from squoosh) and installed it once again via install-all.sh but no luck 😞

When I fire up QuickLook on a webp file for the first time after installation the window gets large like it wants to show an image but then it jumps right back to just file-info. Some internal error I guess :/

Thanks for your help

I also am unable to see the WebP files installing locally or as admin. I'm on 10.14.2. I even sanity tested using WebP files from here: https://developers.google.com/speed/webp/gallery1

I have the same issue, will there be a fix?

Im experiencing the same issue 😭

[grikomsn]

I'm going to do a fresh install on my MacBook and see if it still works.

Update: using the 'install all' script still works like a charm on 10.14.3 🎉

I had a similar issue with another QL extension for webp and found that in my case Pixelmator interfered with it. The instructions here https://github.com/Nyx0uf/qlImageSize#limitations solved the issue for me. Maybe this helps here too?

Solved for me too.

[wottpal]

For me too :)
Just one more question @flekschas: Do you think I have to repeat this each time when Pixelmator updates?

[flekschas]

@wottpal I can't say for sure but I believe you're right. The other day I noticed that I couldn't preview webp anymore and that the setting in Pixelmator's plist was back. Unfortunately, I don't know any way around. Hopefully, someone finds a permanent solution 🤞

Tried it out on 10.14.6!

Some times it generates the thumbs for the webp-files, and it works.
Some times it not works on files that just 2 seconds ago worked!
Generates thumbs for animated images, but will not preview them at all!

Take AGES to generate thumbs! And I'm running a 2,8 GHz i7.

uninstall it and install webp(brew install webp) instead, works on Mojave 10.14.6

@pot-code, when you say "works", what do you mean?

I tried uninstalling this QL plugin, and installing the webp brew formula, but I don't see thumbnails or QL previews (on macOS 10.15.6). I would normally have guessed that the formula would just install libraries, not a QL extension…

[pot-code]

@rgoldberg, As I had installed the plugin(and the webp too), I re-installed it by using the install-all script, but it didn't work. So I did a reboot and uninstalled the plugin via brew cask uninstall WebPQuickLook.

Then I opened the task manager via command+option+esc, selected the finder, and restarted it. Everything now works.

doesn't work von my Mac, macOS 14.6

Frikken Awesome! Thanks everyone! Works great on MacOS Mojave 10.14.6.
Select a webp file, tap space bar, view. Yay! Worked 100% on all 24 webp files I happened to have handy in my Downloads folder.

I installed with:
curl -L https://raw.github.com/emin/WebPQuickLook/master/install.sh | sh
and it was done. Did not reboot.

This Quicklook plugin is So Much Easier than the workarounds I was considering, such as Automator watch folders to watch for any .webp files then calling GraphicConverter to resave as JPG.

Anyway.... Much appreciated! THANKS! :-D
