Ten Mac tricks that hide inside the apps you already have
10 個你不知道的 Mac 必備秘技！學會之後讓你的 Mac 好用 10 倍！
About this video
Eight minutes and ten tricks, and not one of them needs an app you have to install: QuickTime trims and joins clips, Preview merges documents and lifts a page out of a PDF, the Finder renames in a batch, and the Mac can make a phone call. The premise is that macOS already ships the features, which is why the video has outlasted most lists of its kind.
One rule holds throughout: none of these needs an app installed. That is what separates this from the recommendation videos on the same channel — the premise is not that macOS is missing something, it is that macOS has been carrying these features for years and almost nobody opens the apps that hold them.
Four of the ten are media editing, and three of those live in Preview. Merging two PDFs at 1:51, lifting one page out of a document at 2:24, and removing an image’s background at 2:41 are all things people install software for, and all three are in the app that opens by default when you double-click a PDF. QuickTime’s pair at 0:41 and 1:30 — trim a clip, join two clips — is the same story with video.
The Finder items at 4:20 are the ones a heavy user is most likely to already know and a new one is most likely to need: renaming a folder of files in a batch, and the summary panel that tells you how much is in a directory. The trick at 5:45 for hot corners and the one at 6:41 for making a call from the Mac are the two that reach outside the file system — one into the desktop, one into the iPhone.
Recorded in May 2023, on Ventura, so the screenshots are older than the features they show. The shortcuts behind most of these have survived the releases since; the panes they point at have moved.
What it covers
- Nothing in the list requires an install, which is the whole premise: these are features of QuickTime Player, Preview, Finder and Notes that most people never open.
- Four of the ten are media editing, and three of those are in Preview — the app people open for a single image and never explore.
- QuickTime trimming at 0:41 and joining at 1:30 are the two that save the most time, because the alternative is exporting a clip through a video editor.
- Making a phone call from the Mac closes the list at 6:41 and is the only trick that involves the iPhone.

Apps in this video
No app page is linked. Every trick in the video uses a built-in app — QuickTime Player, Preview, Finder, Notes — and no third-party utility appears in it, so none is claimed.
