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, previews 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 .

You might consider simply using QLStephen which will add proper QuickLook support for all text files regardless of their extensions. It will also properly handle files without extensions (e.g. README, Makefile). What I like about it is that you don't have to maintain a list of extensions; QLStephen detects text files automatically. QLStephen is independent ...

QuickLook for these types of files works because the file type is specified in Xcode's Info.plist. In order for QuickLook to use Xcode to quick view these files again in Finder, you'll need to edit Xcode's Info.plist file. This is found by right clicking the Xcode.app file in your Applications and clicking "Show Package Contents". You'll find Info.plist in ...

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 ...

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 ...

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: ...

You can run rm -r /Applications/TextMate.app/Contents/Library/QuickLook/TextMateQL.qlgenerator but you'll have to do that again every time TextMate is updated.

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

You could try adding it via the .plist file. This guide will explain how to do it. To summarize the steps: Go to the applications folder Locate TextEdit.app Show Package Contents Edit the Info.plist file

"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 ...

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 ...

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

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.

When installing Textmate 2 you get QuickLook support for a bunch of data files including XML, Json etc.

Yes, it is possible, but not directly from the internet. The file needs to be downloaded first. qlmanage -p '/path/to/file' will show the quick look preview for that file. It will also write some debug information to stderr, so I usually append >/dev/null 2>&1 to the end of the command. In your case, you will need to download the file first in ...

qlmanage Use the command line tool qlmanage to investigate your QuickLook set up, including the default generator for each file format. qlmanage -- Quick Look Server debug and management tool Apple's QuickLook developer documentation provides a good overview of how QuickLook works and how to test specific plugins.

I do not have that Bug on my MBA 10.9.2 I see you use the XEE as your default app for .jpg and others? There might be a conflict so try disabling the XEE app.

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 ...

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 ...

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 ...
