This "blank Quicklook image" Bug is caused by the activation of the undocumented TextSelection-Feature. As soon as I deleted that feature with this terminal command the blank images were never seen again ;-) defaults delete com.apple.finder QLEnableTextSelection; killall Finder; If this delete-command doesn't work for you, you could try to disable the ...

I've uploaded QuickLook and Spotlight plugins here: https://github.com/Marginal/QLVideo . These allow Finder to display thumbnails, static previews, cover art and metadata for most types of video files, including .asf, .avi, .flv, .mkv, .rm, .webm, .wmf etc. Packaged binary is here: https://github.com/Marginal/QLVideo/releases .

A temporary solution is to press ALT (twice) when presented with a grey image.

It seems this fixed it for me: defaults delete com.apple.finder QLEnableTextSelection && killall Finder I turned text selection in the Quick Look Window on a long time ago. After disabling it, the bug is gone

Open Terminal, and type the following: qlmanage -m plugins This will give you a fairly long list of all your active QuickLook plugins: The types listed there might look a little strange, like com.apple.safari.bookmark. Those are Apple Uniform Type Identifiers or short UTType identifiers, and there is a list of the default ones available from Apple ...

Please notice that the activation of the "Text-Selection-In-Quicklook"-Feature could lead to the bug described in this question: QuickLook having problems displaying some images

You probably have iA Writer installed on your Mac. They recently updated their application to include a Quick Look plugin to show some file types, including .txt, as multi markdown HTML in the Quick Look preview. People have complained that this is intrusive, and the developers have promised a fix in an upcoming update: ...

Install QLStephen, a QuickLook plugin that enables viewing of text files with arbitrary filetypes.

"QuickTime on Mavericks" is not QuickTime anymore - it is "AV Foundation". QuickLook and QuickTime Player are based on this "new QuickTime". "AV Foundation" comes from iOS, was implemented for Mac OS X too and does not offer extensions (and will never) like codecs / plugins. As Apple says: anything else than MPEG-4 (H.264) is old stuff and must be ...

Conversion by QuickTime Player QuickTime Player may be swiftly converting the file on opening using OS X's new AVFoundation. This would explain why it can play the file but not QuickLook or iTunes. It is likely the movie is not in an ideal format for QuickTime Player on OS X 10.9, thus the conversion. With OS X 10.9, Apple dropped native support for many ...

AAC vs AC-3 In my experience, about half the time mkv files are encoded with AAC audio, and half the time with AC-3, and yes this matters. Quicktime will play the AAC and AC-3 formats, but iTunes and iOS media player will not. If the audio in the mkv file was AC-3 and you merely rewrapped it in an mp4 container, it will still have AC-3 encoding on the ...

I just found an interesting workaround for comparing two images or just getting an image to show up: press alt to show image at 100% (and cmd to return image to fit in quick look frame). Even if the image has gone blank, this makes it come back for me. Also, if I'm moving between to files (up and down) and they each keep going blank, I can press alt ...

There's a longstanding request for it at https://issues.apache.org/ooo/show_bug.cgi?id=68600 And an early implementation is at http://eric.bachard.free.fr/mac/aquavcl/patches/aqua_February2008/quicklook/ To install, place OOoQuickLook.qlgenerator from that site into /Library/QuickLook and wait a few minutes for QuickLook to detect the new generator.

I had the same problem. It was caused because I left open a Finder window with a Search which seem it kept refreshing all the time. I just closed that finder tab with the search and the 100% CPU dropped to a normal 3%, and the quicklookd process dissapeared from System monitor's list

FINALLY! Woohoo! This fixed it! defaults delete com.apple.finder QLEnableTextSelection; killall Finder If I had a list of photographs, all with different sizes, going back one image would show the white screen, if i went back a couple more, the images would show up. Going fwd one image would do the same thing. Very consistant, I've tried many fixes. The ...

For OS X 10.8.5, the method below works well enough for me to stop looking for a better solution. The file modification has survived reboots, but it might need to be reset after Apple updates. Edit this sandbox profile as an admin: /usr/share/sandbox/quicklook-satellite.sb Add the file type deny rules at the end and save: (deny file-read* (regex ...

This answer is coming a lot later, but I had to figure this out for myself. Go to where Writer is located Go to where Writer is located. /Applications/ Right click and show package contents Enter Library Delete QuickLook Restart your computer or enter into command line qlmanage -r

Quick Look doesn't make web requests, so it can't show the contents of the webpage without opening it. The question you linked was asking about .html files, with the actual source saved locally. .url files only include a URL, so without downloading the page it can't render anything. You can still use .html or .webarchive files and they will be rendered in ...

For those still looking for this answer, a simple reboot did the trick for me.

Instead of rebooting, you can simply enter "killall quicklookd" in Terminal. That fixed it.

People can develop plugins to allow Quick Look to support more file types. You can find Apple's Quick Look documentation here. Luckily though Timac (aka Alexandre Colucci) has already created one. You can find Timac's Quick Look plugin for strings files here. Just download the compiled plugin, copy it to your /Library/QuickLook folder and run the qlmanage ...
