qlstephen on clean Catalina install

[ptoche]

I used to have qlstephen on my previous (unclean) install of Catalina. Now that I've clean installed it, I'm not sure if it's working at all. For instance, I can't preview text files with extension .in, .ncx, .opf, to name a few. I can preview many other types though.

Here's what I did. Installed the latest QLStephen.qlgenerator in ~/Library/QuickLook and tried also in /Library/QuickLook. I ran qlmanage -r and qlmanage - m. I haven't edited any files inside Contents (InfoPlist.strings is empty, if that matters).

The first few lines of qlmanage -m look like this:

 qlmanage -m

  com.apple.iconset -> /System/Library/QuickLook/Icon.qlgenerator (906.2)
... and many more lines

Same here. I installed on a new macbook with 10.15.5, via homebrew, and I don't see any previews available e.g for .yml

check if it code signed, if it not it will not load on 10.15.5.

qlmanage -m | grep QLS codesign -dvvvv /Library/QuickLook/QLStephen.qlgenerator/

Thanks for the feedback. Here's what I get:

Having the same issue on macOS 10.15.6 via Homebrew. This is the message I was getting on boot. I was able to fix by running this command, which I have used for other improperly signed stuff.

xattr -d com.apple.quarantine ~/Library/QuickLook/QLStephen.qlgenerator Not sure what the 1.5.1 update of QLStephen did for Catalina compatibility?

[fuzunspm]

xattr -d com.apple.quarantine ~/Library/QuickLook/QLStephen.qlgenerator

this won't work on my side:

xattr: /Users/username/Library/QuickLook/QLStephen.qlgenerator: No such xattr: com.apple.quarantine

and all i see is blank white preview on all file types except txt and md

@fuzunspm I get the same "no such xattr" when I run that, but if I go inside the folder and run it on the executable, it doesn't give me an error. I haven't given it much time to see if it fixes the popup, but maybe give this a shot?

xattr -d com.apple.quarantine ~/Library/QuickLook/QLStephen.qlgenerator/Contents/MacOS/QLStephen

[DKroot]

xattr -d com.apple.quarantine ~/Library/QuickLook/QLStephen.qlgenerator worked like a charm on my Catalina 10.5.7.

[theRealPadster]

And just an update on my attempt with xattr -d com.apple.quarantine ~/Library/QuickLook/QLStephen.qlgenerator/Contents/MacOS/QLStephen It did not work.

[DKroot]

Since xattr -d removes the attribute, it could be done only once. If you get No such xattr message, it means that it has been already done and if the issue still occurs, the problem has some other cause.

[theRealPadster]

Fair point. I just thought it might have been re-added with some update or something.
