According to System Preferences, the Downtime feature of Screen Time "[s]ets a schedule for time away from the screen. During downtime, only apps that you choose to allow and phone calls will be available." Downtime blocks most apps, but it does not block Finder. It blocks the Quick Look feature of Finder for video but not audio or PDF. How can I block Quick Look for all file types during downtime? Alternatively, can I force a log out during downtime? As I recall, the Restrictions feature that preceded Screen Time could force a log out. If Screen Time cannot do this, then what parental control apps can?

I have been using MacBook pro-2017 for about a year, in the mean time I have added a couple of quiclook generators (e.g. QLStephen.qlgenerator) for various services for the Finder. For quite a few days it was working good, but now, I encountered a strange problem. Nowadays I can not see the contents of any file in the finder, e.g. when I click on a a.txt file it shows no contents, but when pressed Shift key it shows the QuickView of the item. How to restore the original settings of the Finder? I tried deleting all the quicklook plugins, but still, the problem is sustained. Attempt: cd ~/Library/QuickLook sudo mkdir backup sudo mv *.qlg* backup/ qlmanage -r killall Finder PS: I tried also deleting all the contents of QuickLook and restarted the computer. Still it does not work. Maybe I have to reset the Finder settings, but I don't know how? Note that here the a.txt is not empty but Finder shows nothing. **How can we make the Finder show the contents of this file?** **Update** Backed up and deleted the QuickLook folders from the computer. sudo mv /Library/QuickLook ~/library_quicklook sudo mv ~/Library/QuickLook ~/home_library_quicklook sudo rm -rf com.apple.quicklook.ui.helper.plist sudo rm -rf com.apple.quicklookconfig.plist sudo rm -rf com.apple.QuickLookDaemon.plist qlmanage -r qlmanage -r cache killall Finder Still does not work.

In macOS Monterey, when I quick look files located on NFS shares, the modify date/time has been changed. How can I prevent this?

Is there a Quick Look plug-in that works with ZIP files, and that lists all the files contained in the archive? It is also fine if it lists at least some of the files.

On macOS 10.14.6 and MS Office 16.32 (latest version), quicklook previews only show the icon for .doc and .docx files. I have checked qlmanage, and cleared its cache:

~ qlmanage -r cache
qlmanage: call reset on cache
~ qlmanage -r
qlmanage: resetting quicklookd
~ qlmanage -m | grep microsoft
  com.microsoft.powerpoint.pot -> /System/Library/QuickLook/Office.qlgenerator (39 - loaded)
  com.microsoft.word.doc -> /System/Library/QuickLook/Office.qlgenerator (39 - loaded)
  com.microsoft.word.dot -> /System/Library/QuickLook/Office.qlgenerator (39 - loaded)
  ...

But still no joy. Most of the files are created by someone else on a PC (also running latest version of MS Office), and shared over Google Suite. Will that stop this feature from working? Are there any work-arounds?

I recently updated to Ventura and I lost a feature I didn't realize I depend so much on. Previously when I took a screen shot (typically using ⇧ Shift ⌘ Command 4 ), when I clicked the floating thumbnail it would open the Preview but already in the markup editor. Unfortunately, I am now forced to click the markdown icon every single time which is frustrating; nearly every time I take a screenshot I intend to add some type of annotation. Is there a way to restore this or change the settings? ***Note:** I have noticed that my phone opens in markup each time but I would prefer to use my current device to make the annotations*

Something broke my quicklook's preview copy shortcut and now when I have a document in preview and select text, hitting cmd+c plays the error sound and the text does not get copied. I can still copy from the right click context menu or if I go in the menu edit > copy. I think it may be due to Raycast, but turning it off and rebooting did not fix the issue... Neither did qlmanage -r cache, nor a multitude of changes in com.apple.finder QLEnableTextSelection Anyone have any other suggestions? Edit: I have talked with a few friends and can confirm this is **not** due to Raycast, as I had three people who do not use it, or any other clipboard manager, tell me they have the same issue. Is it a macOS 15.2 bug? Update: I checked and found that the files that not all files have an issue, specifically .txt, .rtf and .pdf have no issue, however, .docx, .pages, .csv, .numbers, .md and pretty much anything else does. I think it might be an issue office/iWork and quicklook, so I did a qlmanage -p on a docx. And I did indeed got some errors:

qlmanage[7015:63047] NetworkStorageDB:_openDBReadConnections: failed to open read connection to DB @ ~/Library/Caches/com.apple.quicklook.qlmanage/Cache.db.  Error=14. Cause=unable to open database file

(I removed the timestamps and abbreviated the User path to ~) Needless to say this does not happen when I call the same command on a pdf

I'm on Ventura 13.0.1 (22A400). In the past I was able to take a screenshot (CMD+SHIFT+4), click on the thumbnail in the corner of my screen opening the "Quick Look", and immediately begin drawing on the screenshot. The markup toolbar was always enabled by default. Recently, the toolbar is never enabled, so I have to click on the button to display it, then click on the button to select the "Sketch" tool. This is two clicks more than before! I assume that this is due to the addition of the ability to copy text from any image, as the text selection cursor is now the default. But I use the Sketch tool hundreds of times more than the text selection tool. Is it possible to change back to the old default behaviour, where Quick Look defaults to the Sketch tool?

So, coming across what [QLStephen](https://github.com/whomwah/qlstephen) could do, I brewed it at once in the hopes of having the Quick Look functionality for most of the "text-based" files, as it advertises. However, to my disappointment, nothing was affected. I found temporary relief to find that the exact issue had been discussed [here](https://apple.stackexchange.com/a/411423/495879) , but the suggested troubleshooting didn't help. Here's what all I did: 1. Ran brew install qlstephen which installed QLStephen.qlgenerator in ~/Library/QuickLook. Quick Look didn't preview any more files than those for which it was already working without QLStephen. In particular, all of the hidden files in my user directory are still non-preveiwable. These include: .bash_history, .CFUserTextEncoding, .gitconfig, .lesshst, .profile, .python_history, .Rhistory, .viminfo, .Xauthority, .zprofile, .zsh_history, .zshrc, mbox 2. [cf. the troubleshooting post mentioned above] The UTI of each of the files listed above is public.data, and QLStephen is supposed to act on these, but nope! 3. [cf. **Permissions (Quarantine)** on the GitHub page for QLStephen] Ran sudo xattr -cr ~/Library/QuickLook/QLStephen.qlgenerator, qlmanage -r and qlmanage -r cache followed by relaunching Finder. Still nothing. 4. [cf. **Trouble** on the GitHub page for QLStephen] Ran qlmanage -m and couldn't find public.data, indicating that "a different application's qlgenerator file hasn't taken precedence". Now the next troubleshooting steps are not at all clear—they just mention to edit some files, but not *what* to edit. 5. Tried brew reinstall qlstephen ample times, but still, nothing budged. **System info:** macOS Sequoia 15.1 on M2 with Xcode installed.

Is there any way to remove the rounded corners of the image preview in Quick Look? Maybe some hidden preference? I have to preview large amount of small images (assets for the applications I develop), and these rounded corners interfere a lot. For example compare the QuickLooked (left) with the actual image (right). Thanks!

Source code files viewed using Quick Look on Snow Leopard had syntax highlighting. Unfortunately the syntax highlighting has disappeared on OS X Lion. Is there a way to get it back?

I have a bunch of data files that are .txt files that I would like to be able to view as plots via Quick Look. Is there a plugin (or other easy way, e.g., a setting, .etc) to do this? The values are all tab-delimited and one-dimensional, so it might not be too hard to code something that can do this, but I am probably overlooking something trivial.

In Lion if I used QuickLook to display an image, and then clicked the double arrows to make it full screen, it would scale the image to the size of my monitor (up too, not just down). Then when I used the arrow keys to navigate in the Finder, all subsequent small images would also display scaled up. That no longer happens. In Mavericks, small images are now displayed at 100% with a black border around all four sides. You can scale individual images up by tapping the Option key, but that only applies one image at a time, not the whole series. Is there any way to get that setting back? I used that feature a lot, and it's rather disconcerting that it's gone.

Doing *Quick Look* on .txt files is very convenient (select in *Finder* and press space). Is there a way to enable Quick Look for other text files which don't have the .txt extension (e.g., .strings files)?

I'm a programmer, and I find Mac's QuickLook a really great feature for quickly becoming familiar with a particular code base. Basically, I open up a Finder window in the directory where my code files are, I push the spacebar (to evoke QuickLook), and then I arrow key up/down/left/right through all the files and scroll within QuickLook as needed. The problem that I run into are files with no extension and files with unknown extension. How can I convince the Mac to attempt to QuickLook these files as text files (which they usually are). Also, it's really nice how QuickLook automatically colors the code based upon the type of code it thinks it is. How can I extend the types of code files that the Mac recognizes? For instance, I want to be able to QuickLook the code in a *.html.erb file or a *.js.erb file.

I'm trying to do what should be a fairly simple task: have Finder and Quick Look view .md and .markdown files as if they had the extension .txt. As per previous answers on this topic, I had installed the QLMarkdown plugin in my /Library/Quicklook to make this happen, and it was working fine for a while. Recently I had a hardware disaster that required Apple to wipe and replace my hard drive, with the new one running Monterey. In this new system, the QLMarkdown plugin is not working. I tried copying the latest version (1.3.6) into the /Library/Quicklook and, as per the readme , I ran qlmanage -r in the terminal to refresh. Then I got an error from Apple saying it would not run because Apple could not check it for malicious software. No option to override. The previous answers suggest I could install Homebrew and run "brew cask install qlmarkdown", but following the [Homebrew install instructions](https://brew.sh/) wound up causing a system freeze and reboot - and QuickLook wasn't working any better after that. How do I get QuickLook to recognize Markdown on Monterey under these circumstances?

I'm experiencing multiple bugs with QuickLook since Catalina. They are still present on Big Sur 11.1. 1°) Reversed slideshow To reproduce: - select multiple pictures - press space bar - the slideshow order is reversed: the last picture is displayed instead of the first, and we have to use the left arrow to display the next picture It also happens in fullscreen. 2°) Alt key no longer zooms to 100% Previously we could press the alt key to zoom at 100% (one pixel of the picture = one pixel of the monitor). It was perfect to see quickly know if a picture is sharp or not. Now we have to press MAJ-CMD-0 to zoom, MAJ-CMD-9 to unzoom. And in Preview.app, it's not MAJ-CMD-9/0, but ALT-CMD-9/0. o_O 3°) Two-fingers double-tap to zoom does not go back To reproduce: - select a picture - press space bar - execute a two-fingers double-tap on the trackpad (or one-finger double-tap on a Magic Mouse) -> it zooms to 100% (or 200%, see #4 below) - do it again. We'd expect it to unzoom, but it instead zooms to 200%, and we can't go back to see the entire picture with that gesture. The only way is to execute a pinch, which takes much more time to do. 4°) HiDPI monitors are not correctly supported To reproduce: - use a HiDPI monitor (say a 27" 4K monitor) - select a photo (say a 1600px * 900px picture) - press space bar - the picture is displayed at twice its size (like if it was 3200px * 1800px), making it pixelated. When using the MAJ-CMD-9/0 shortcut to zoom/unzoom to 100%, it instead zooms to 200%, making the feature useless to know if it's sharp or not. 5°) Scrolling no longer works in fullscreen index sheet view To reproduce: - select many photos - press alt-space to start QuickLook fullscreen - open the index sheet - try to scroll having your cursor above the background, it does not work. If your cursor is above a picture, it does. The problem does not happen if we're not in fullscreen. 6°) There's a weird flickering when opening the index sheet view To reproduce: - select many photos - press alt-space to start QuickLook fullscreen - open the index sheet - the animation is broken: the thumbnails first appear above the image that was displayed fullscreen, then that image comes back above the thumbnails and is animated, and finally the thumbnails are back. Does someone managed to fix at least a few of them? Thanks EDIT: I submitted a bug report, please upvote if you want it to be fixed: https://discussions.apple.com/thread/252189076?sortBy=best

Some time recently (possibly with the Ventura upgrade; I'm not sure) quicklook behaviour got worse. In particular, *.tex (TeX/LaTeX) files stopped previewing entirely; instead they show a message > The extension com.apple.tips.TipsAppQuicklook-macOS does not implement file previews which seems to be weirdly trying to assign the quicklook to something related to "Tips". I note * ~/Library/Application\ Scripts/com.apple.tips.TipsAppQuicklook-macOS exists, but it is an empty folder. * mdls -name kMDItemContentType gives kMDItemContentType = "org.tug.tex" * I *think* the previews used to be handled by TextMate which also showed full syntax-highlighted previews. TextMate still has an org.tex.tug entry in its Info.plist. * Preview icons are still shown correctly. * Most other text file types seem to work, albeit without syntax highlighting, with an "Open with _some app_" button on the top of the preview window, pointing to TextEdit, Xcode, Textmate, or even Emacs depending on the file type. (Emacs files seem to get syntax highlighting?!) * org.tug.tex does not appear in qlmanage -m plugins, although org.tug.tex.bibtex and org.tug.tex.dvi do. * There is no ~/Library/QuickLook directory. * I have tried qlmanage -r, qlmanage -r cache and a restart, to no avail. Other people have similar problems, as seen on [tex.SE](https://tex.stackexchange.com/questions/663924/quicklook-on-macos-ventura-not-working-anymore-for-tex-files) **Update**: This [Apple support forum thread](https://discussions.apple.com/thread/254334388) seems to have some more information. It implies that Apple has deprecated old quick look generators, but I don't think that this can be the whole problem, since it seems to work -- including via TextMate -- for some types. **Update 2**: not fixed in 13.1, alas. **Update 3**: [This app](https://github.com/sbarex/SourceCodeSyntaxHighlight#install-with-homebrew-cask) seems to work as a quicklook previewer for a wide variety of file types, including TeX and CSS. (Thanks to [this answer on the related thread](https://tex.stackexchange.com/a/667435/72039).) Any ideas?

Currently, I can use the space bar to preview a number of files such as .txt, .css, .html etc in Quick Look. I cannot, however, see the actual contents of a .json file. Is there any possible way to see the contents of .json files through space bar preview in finder? (I'm Using OSX 10.8.4)

* macOS 13.6 Ventura * Mac Mini M1 Can someone remind me how to get QuickLook to display .mojo files, or any unknown file to display its contents. Some of my code source files display with code highlighting and everything, but .mojo files do not even display in plain text. There's nothing special about .mojo files; they're just plain text files. Indeed, I've already got them configured to open in Cursor editor when double-clicked. It's just [space] that doesn't work.
