With that in mind, here are few quick macOS tips that once you start using should make the time you spend on your Mac a more effortless experience. The following assumes you're running macOS Sonoma or later, but many of these tips should work on earlier versions of Apple's Mac operating system.

Access more Preview file format options

When you come to save or export a file in Preview, Option-click the Format dropdown to get access to several additional file types.

Float notes over app windows

In the Notes app in macOS, it's possible to float individual notes over other windows so that they stay visible regardless of which application is active. This makes for a convenient way to reference an existing note while writing an essay or report, for example. It also comes in useful if you want to take notes when researching something online.

To float a note in the Notes app, double-click the note to open it in a separate window, then select Window -> Keep on Top from the menu bar. The note will now remain above other open application windows, even if you switch between apps using Stage Manager. Just remember that your floating notes can't share the same screen as another app that's in fullscreen mode.

Add app, file or folder shortcuts to Finder's toolbar

Simply begin to drag the item within the Finder window, then hold down the Command (⌘) key and drop it onto an available space in the toolbar.

Quickly access specific system settings

If your Mac's keyboard has icons printed on some of the functions keys, you can press them to perform special features. For example, pressing the F11/12 keys with speaker icons adjusts the volume. If you hold down Option when you press one of these keys, the specific preferences in System Settings that are associated with the feature will open instantly. Option-F11/12 opens the Sound pane, for instance.

Tired of Typing? Dictate

macOS supports simultaneous use of keyboard input and Dictation, without any disruption in your flow of thought. In other words, you can keep typing after hitting the Dictation shortcut (assignable in System Settings... > Keyboard). So whenever your fingers need a rest, you can complete the sentence you were just typing by saying it out loud.

Automatically close Safari tabs

macOS can close Safari's browser tabs on your behalf, based on when you last viewed them. Select Safari -> Settings... in the menu bar, then click the Tabs section. Next to "Automatically close tabs" you'll find options to make the browser auto-close tabs that have not been viewed After One Day, After One Week, or After One Month.

Mail attachment downloads in Finder

In macOS Sonoma or, when you download an email attachment from Mail and view it in Finder, the file includes a new mail symbol next to it to let you know it's an email attachment. If you right-click the attachment, there's even a "Reply to [name of sender]" option in the contextual menu that when selected will open the Mail compose window, ready for you to type up your reply message.
