You just prove the point of the author above.

If you had the real Preview on MacOS, you’d be using it all the time without even thinking, like 100% of MacOS users. Because it’s fast, it opens everything faster than you can think, and it just works well. The effort required to launch it is zero, or even negative. It’s just part of the OS.

But since you have a « sort of » copy cat which does not work as well or as fast, is not as well integrated, does not support as many files or any fatal flaw like that, you just don’t use it.

So yes, Preview is underrated and really hard to replicate.

I wasn't talking about Preview, I was talking about quick look, i.e. when I browse files in my file browser, I can hit space and immediately look at that file in a pared-down interface. But I'm not browsing my files that often, and when I do, the only time I seem to be interested in what it looks like is when I'm looking for an image, in which case the thumbnails that I can see without interaction suffice.

So I'm probably missing something. Does that mean that, because it's so fast and low-effort, you use it as a complete replacement of a native app you'd use otherwise? And then just for files you're just consuming, or does it also work for editing? And what kind of files?

Note that I'm not out to prove any point, I just want to understand what I'm missing :)

In my case, yes. It’s the only way I ever look at images, and I often use it to have a quick look at scripts or text/data files (try it on a CSV and it’ll show as a table!). It’s also convenient for design files, whose apps are incredibly slow to launch. With Alfred[1] you can even preview URLs directly.

Finally, QuickLook shines when you have file formats for which you don’t have an editor (e.g. you may need to view a Photoshop or Word document once in a while). It allows you to view them faster than in the editing application, for free, without having to install or configure anything.

Unlike the swath of people who are singing praises to Preview, I rarely touch it and mostly resort to QuickLook, even for PDFs.

It works (at least) to edit images like Preview (annotate, rotate, crop).

Thanks, I suppose I should make an effort to think of it when I look at local images or PDFs (which I don't do that often) - although edit doesn't seem to be supported by my version of it, unfortunately. CSVs or files without an editor I don't think I ever touch :)

It's faster, and less jarring when it opens due to animating FROM the file). It also works in Open / Save dialogue windows in any app which the equivalent does not.

That little "wait is this the file I want to open / overwrite?" When saving a file, it adds to an overall feeling of polish.

Like a tasty meal, it's all in the details and how they add up

quick look spreadsheets when you don't want to wait half a minute for excel to load. Quick look pdfs with nondescript names that you've downloaded to check paper titles/authors, quick look ppts youve been emailed (from within the email app) to see if they're worth reading in depth.
