Mac How-To guides

Most macOS tasks have a fast route and a slow one, and Apple rarely puts both in the same place. These guides give you the shortcut first, then the longer menu path for when the shortcut is disabled, remapped, or unavailable in a locked-down app.

Start with the shortcuts you will use daily. Taking a screenshot covers all five capture modes and the modifier keys that refine a selection while you drag; screen recording covers the same toolbar's video side, including the reason macOS cannot capture system audio without help. Copying and pasting sounds trivial until you need plain text or want to move a file rather than duplicate it, and right-clicking trips up nearly everyone arriving from Windows, because Apple calls it secondary click and hides it accordingly.

For everyday file work, unzipping and creating archives explains what macOS opens natively and what it refuses to touch, cropping a picture compares Preview's destructive edits with the non-destructive route through Photos, and compressing a PDF is honest about when the built-in filter helps and when it wrecks your images. Hiding files is included with a warning attached: hiding is cosmetic, and anything that genuinely matters needs encryption instead.

Several guides here exist because the setting is not where people look for it. Increasing the screen timeout lives under Lock Screen rather than Displays, and splits across two independent values for battery and mains power. Opening Task Manager means finding Activity Monitor, which is not called Task Manager anywhere in macOS. Changing your password is complicated by there being two passwords, and by what a reset does to your keychain.

The rest cover the tools you reach for occasionally and then forget. Opening Terminal includes the safety rules that matter more than the commands. Splitting the screen distinguishes Split View from the newer window tiling, which behave very differently despite looking alike. Typing emoji opens a picker that also holds arrows, currency, and mathematical symbols. Connecting AirPods covers both the no-setup path and what to do when a stale pairing blocks it.

Every guide here is written against a current macOS install and says so when a step changed between releases. Where a task has a supported route and a Terminal route, we lead with the supported one — Terminal is genuinely better for a handful of jobs and genuinely riskier for the rest. If your Mac is misbehaving rather than merely unfamiliar, the maintenance guides are the better starting point.

A note on how these are written. Each guide opens with the answer, because most people arriving here want one specific keystroke and not an essay. The detail underneath is for the cases where the simple answer fails — a shortcut claimed by another app, a permission that was never granted, a setting an employer has locked down. Where a step depends on your Mac's processor or macOS version, that is stated inline rather than assumed. And where a task is genuinely riskier than it looks, the guide says so plainly instead of burying the caveat: Terminal will do exactly what you tell it including destroying your system, and hidden files are not private in any meaningful sense.
