Mac Accessibility for Vision,
Tremor & Hearing

These settings aren't a consolation prize

Apple files a remarkable set of tools under a word almost nobody goes looking for: Accessibility. Screen magnification, a professional-grade screen reader, keyboard settings that forgive a tremor, full control of the computer by voice, live captions for anything playing through the speakers. It is all included with macOS, none of it costs a penny, and none of it announces itself to anyone else who sits down at your Mac.

I want to be plain about the framing, because it's the part that stops people. Turning these on is the same kind of adjustment as sliding the car seat forward or putting a lamp behind your reading chair — you're setting the machine up to fit you instead of the other way around. Plenty of folks with sharp eyes and steady hands use half of what's on this page, because it's simply better. Change one thing, live with it a week, and change another only if you want to.

The one shortcut worth memorizing: Option-Command-F5

Press Option-Command-F5 anywhere on a Mac and a small Accessibility Shortcuts panel appears — checkboxes for VoiceOver, Zoom, Sticky Keys, Slow Keys, Full Keyboard Access and more, so you can flip a feature on or off without hunting through menus. On a Mac or Magic Keyboard with Touch ID, pressing the Touch ID button three times quickly opens the same panel. It even works at the login window, which matters if the screen is too small to read your own password field. If pressing F5 changes the keyboard backlight instead, hold the fn key (or the globe key) along with it. The long way to everything is Apple menu → System Settings → Accessibility, in the left-hand sidebar.

Vision: Zoom, Hover Text, and having your Mac read to you

• Hover Text — System Settings → Accessibility → Hover Text. Turn it on, then hold the modifier key it shows you (Command, out of the box) and point at anything. A large, high-resolution copy of just that item appears in its own window, in whatever font, size and colors you choose. Let go and your screen is exactly as it was.
• Zoom — Accessibility → Zoom. Magnify the screen with a keyboard shortcut, a trackpad gesture, or by holding a modifier key (Control by default) while you scroll. Zoom style can be Full Screen, Split Screen, or Picture-in-Picture — a floating magnified window that follows the pointer. Start with Picture-in-Picture; it's the least disorienting.
• Spoken Content — Accessibility → Spoken Content. Turn on Speak selection, note the keystroke (Option-Escape out of the box), pick a voice, and slow the speaking rate down. Now highlight any article or long email, press the key, and listen. This is the feature I recommend most and almost nobody knows about.
• Losing the pointer? Shake the mouse and it balloons up for a second. Permanent pointer size, outline and fill colors live under Accessibility → Display.

VoiceOver: what Command-F5 actually does

Command-F5 turns VoiceOver — Apple's built-in screen reader — on and off. The same keys work in both directions, which is worth knowing because that's also how people switch it on by accident. If your Mac suddenly starts describing every button in a calm voice with a black rectangle following the pointer, nothing is broken and nothing is lost: press Command-F5 again. Used deliberately, VoiceOver is a genuinely professional tool that people run careers on, and it has a real learning curve — closer to a stick shift than a light switch. Take the Quick Start tutorial it offers the first time (about fifteen minutes), slow the speaking rate down in VoiceOver Utility, and learn six commands: Control to silence it, Control-Option as the “VO keys”, VO-Right/Left Arrow to move, VO-Space to click, and VO-A to read from here down. If magnification still works for you, Spoken Content will serve you better for far less effort.

Shaky hands: Sticky Keys, Slow Keys, key repeat and Mouse Keys

• Sticky Keys (Accessibility → Keyboard) lets you press Shift, then Command, then Q — one key at a time — instead of holding all three at once. Capital letters still work the old way; it adds a method rather than replacing one. There's an option to toggle it by pressing Shift five times.
• Slow Keys (same panel) makes the Mac ignore a key unless it's held briefly, so a tremor or a knuckle grazing the row above doesn't produce stray letters. Start with the shortest acceptance delay and lengthen only if needed.
• Key repeat is not under Accessibility — it's System Settings → Keyboard. Set Key repeat rate to Off and a held key types exactly one letter, no matter how long your finger rests. That single change ends the “helloooooo” problem for good.
• Mouse Keys (Accessibility → Pointer Control) moves the pointer with keyboard keys, no mouse required. There's an option to turn it on by pressing Option five times.
• The dials nobody finds: slow the double-click speed if double-clicks aren't registering, lengthen the spring-loading delay if folders keep opening on you, and turn on ignore built-in trackpad when a mouse is present if your palm keeps brushing the laptop trackpad.

Voice Control: running the whole Mac by talking to it

Voice Control isn't Siri, and it's more than dictation. Switch it on at System Settings → Accessibility → Voice Control (scroll down to find it) — the first time, your Mac downloads a file so it can understand you, so be on Wi-Fi. Then you can say “Open Mail”, “Scroll down”, “Click Done”, “Undo that”, “Correct that”, and — the one that changes everything — “Show numbers”, which puts a little number beside every clickable thing on screen so you can just say the number. “Go to sleep” stops it listening and “Wake up” starts it again; memorize that pair first. Apple designs it to do its listening on the Mac itself. Even if you never use it daily, turn it on once so you know it's there — the afternoon after a wrist surgery is a bad time to be learning it from scratch.

Hearing: Live Captions, mono audio, and hearing aids

• Live Captions (Accessibility → Live Captions) puts on-screen text of audio playing on your Mac — a FaceTime call, a video, a podcast — in a window you can resize and restyle. Two honest limits: it requires an Apple-silicon Mac (the M-series chips; Intel Macs can't run it), it isn't offered in every language or region, and the captions are software-generated. Good, not perfect. Don't rely on it alone for a doctor's video visit.
• Mono audio — Accessibility → Audio → Play stereo audio as mono. If one ear hears better than the other, stereo is sending half the soundtrack to the ear that can't hear it. This combines both channels into both ears. Five seconds, reversible, and often startling.
• Alerts you can see — also under Audio, “flash the screen when an alert sound occurs” blinks the display instead of beeping. Background Sounds plays steady rain or ocean, which many people with tinnitus find helpful.
• Captions styling — Accessibility → Captions sets how subtitles look across apps: bigger text, solid background, no more white words on a white shirt.
• Hearing aids — aids certified “Made for iPhone” (MFi) pair under Accessibility → Hearing Devices; ordinary Bluetooth aids usually connect through System Settings → Bluetooth instead. AirPods Pro hearing-aid setup happens on an iPhone or iPad, not the Mac — see my Hearing Aids & Bluetooth guide for that side.

Where to start, and what to watch out for

1. Press Option-Command-F5 once so you know the panel exists.
2. Turn on Hover Text and point at three things.
3. Turn on Speak selection and have it read one paragraph.
4. Turn on Sticky Keys and try Command-Q one key at a time.
5. Turn on Play stereo audio as mono and replay something familiar.
6. One safety note: everything above is free and already installed. You never need to download a “screen reader” or a “magnifier,” and nobody legitimate needs remote access to your Mac to change an Accessibility setting. Change settings only from Apple menu → System Settings — never from a link, an email, or a pop-up. And no software on a computer treats hearing loss, whatever an ad says.

Why I wrote this

I write these as printable handouts because a guide you can tape inside a cupboard door beats a web page you have to find again. This one exists because I kept meeting people who'd quietly stopped doing things on their Mac — reading the news, watching a video call, typing a long email — when a switch that was already on their machine would have handed it back. Nobody had ever shown them where it lived, and the word “Accessibility” put them off looking. That's a solvable problem, and it shouldn't cost anybody a dime. If you'd rather have someone sit beside you while it's set up, that's a $99 flat first visit with the 30-day follow-up included — which matters here, because some of these settings you only know you love after living with them a couple of weeks. — Bill
