Apple product names

Apple product names follow set rules for capitalization, spacing, and hyphenation. Mistakes like "Mac OS", "airpods", or "i phone" are common-and easy to fix by using Apple's exact tokens and applying a simple hyphenation rule for compound modifiers.

Quick answer: the most common corrections

Use Apple's official forms: iPhone, iPad, iPadOS, macOS, MacBook, MacBook Pro, AirPods, AirPods Pro, Apple Watch, HomePod mini. Don't invent spaces or change case. Hyphenate only when a full compound modifies a following noun (e.g., iPhone-compatible case).

Always capitalize the company name: Apple.
Copy exact product tokens: macOS (lowercase m), iPhone (lowercase i, capital P), AirPods (capital P).
Hyphenate only for pre-noun compounds: iPhone-compatible charger; not: charger compatible with the iPhone.

Core rules - the minimal set to remember

Three checks every time you write a product name: (1) Is "Apple" capitalized? (2) Is the product token exactly as Apple spells it? (3) If the phrase modifies a noun before it, do you need a hyphen?

Company: Apple (always capitalized).
Device tokens: iPhone, iPad, iMac, MacBook, AirPods, Apple Watch.
OS tokens: macOS, iPadOS, watchOS, tvOS (single-token styling).

Wrong: apple -
Right: Apple
Wrong: Mac OS -
Right: macOS

Spacing and concatenation mistakes

Most errors are extra spaces or missing capitals inside tokens Apple treats as single words.

Do not split tokens: iPhone (not i phone).
Keep Apple's spacing for hardware families: MacBook Pro (two words), HomePod mini (two words).
OS names are single concatenated tokens: iPadOS, watchOS, macOS.

Wrong: i phone 12 -
Right: iPhone 12
Wrong: Macbook Pro -
Right: MacBook Pro
Wrong: iPad OS -
Right: iPadOS
Wrong: Homepod mini -
Right: HomePod mini

Hyphenation, punctuation, and possessives

Hyphenate compound modifiers that come before a noun; otherwise don't. Form possessives and plurals as usual but keep Apple's capitalization.

Before a noun: iPhone-compatible case (hyphen).
After a noun: This case is compatible with the iPhone (no hyphen).
Possessives: the iPhone's camera; AirPods' battery life (AirPods is plural).

Wrong: iPhone compatible case -
Right: iPhone-compatible case
Wrong: Airpod's battery -
Right: AirPods' battery
Wrong: the macbook's screen -
Right: the MacBook's screen

Capitalization pitfalls

Apple deliberately uses lowercase on some tokens. Follow Apple's casing rather than "title case" rules for those tokens.

Apple (company) - capitalized.
iPhone, iPad - lowercase initial i; macOS - lowercase m.
Modifiers: Pro, Max, Air are capitalized; "mini" is lowercase in "HomePod mini."

Wrong: Mac OS Big Sur -
Right: macOS Big Sur
Wrong: homepod Mini -
Right: HomePod mini
Wrong: iPad pro -
Right: iPad Pro

Memory tricks and a quick pre-send checklist

Fast mnemonics and a short checklist make proofreading quick.

Mnemonics: "i lower, P upper" → iPhone. "m lower" → macOS. "Pods" is capitalized → AirPods.
Three-step pre-send check: (1) Is "Apple" capitalized? (2) Is the product token exactly Apple's styling? (3) Are hyphens and possessives correct?
Add top wrong→right pairs to autocorrect (Macbook → MacBook, airpods → AirPods, Mac OS → macOS).

Similar mistakes to watch for (other brands and OS names)

The same patterns-incorrect capitalization, spacing, hyphenation-appear with other brands. Fix them the same way: use the brand's official form and hyphenate compounds before nouns.

FAQ

Should I write Mac OS or macOS?

Write macOS. Apple uses a single token with a lowercase "m" followed by uppercase "OS."

Is iPadOS one word or two?

Use iPadOS (one word). Apple combines iPad and OS into a single token, like macOS and watchOS.

Do I always capitalize "Apple"?

Yes. Always capitalize "Apple" when referring to the company or as part of a product name (Apple Watch). Only certain product tokens start with lowercase letters (e.g., iPhone, macOS).

When should I hyphenate "iPhone-compatible"?

Hyphenate when the compound appears before a noun: iPhone-compatible case. If the phrase follows the noun, no hyphen: This case is compatible with the iPhone.

How do I pluralize and form a possessive for AirPods?

The product name is AirPods (plural). Possessive: the AirPods' battery life. If referring to a single earbud, use AirPod and AirPod's.
