Few days ago, someone tweeted about this online document from Apple called Apple Style Guide. It's the first time I heard about it and I'm pretty sure I'm not the only one. After skimming the document, I found many interesting tidbits about microcopy and copywriting. So this weekend, I decided to read everything.

For native English speakers, the content of this Apple Style Guide might not be so interesting, but for those who use English as second language, this document could help you make your apps or products better, especially if your apps are using English.

If you don't have the time to read everything, I curated the document in this article. Most of the things mentioned in the document is to avoid confusion and ambiguity for the users of Apple apps. I picked some parts that I found interesting, or even new to me.

activate, deactivate

Avoid; instead, use turn on, turn off.

alert

In user materials, you can use alert sound or alert message to describe generic alerts. Avoid error message except in developer materials.

The computer plays a sound (called the alert sound) when it needs your attention.

An alert message appears if a problem occurs during the installation.

In specific situations, however, avoid the word alert if you can simply describe what happens.

A message appears when the installation is finished.

allow

Avoid using allow when you can restructure a sentence to make the reader the subject.

Avoid: FileMaker Pro allows you to create a database.

Preferable: You can create a database with FileMaker Pro.

alternate, alternative

Use alternate to mean every other or occurring or proceeding by turn. Use alternative to mean allowing two or more choices.

You can shade alternate rows of a table.

When traffic is heavy, Apple Maps provides alternative routes.

Rewrite to avoid this construction.

Correct: document and app icons

application-based services, Windows-based computer

Use an en dash (Option-Hyphen) if based follows a term with two or more words.

Windows XP–based computer

Don’t use a hyphen or an en dash in predicate adjectives that include based.

Each track in a sequence is assigned an index value that is zero based.

blank character

Don’t use; use space character.

braces

Use braces, not curly brackets, to describe these symbols: .

When you need to distinguish between the opening and closing braces, use left brace and right brace.

brackets

Use brackets, not square brackets, to describe these symbols: [ ]. Don’t use brackets when you mean angle brackets (< >).

When you need to distinguish between the opening and closing brackets, use left bracket and right bracket.

browser, Internet browser, web browser

bug

Avoid; use problem, condition, issue, or situation instead.

built-in (adj.), built in (pred. adj.), built into (pred. adj.)

In headings that use title-style capitalization, don’t capitalize in (exception to the rule of capitalizing the second word of a hyphenated compound).

Built-in Apps on Your MacBook [heading]

You can use the built-in microphone or an external microphone.

Mac Pro has 512 GB of flash storage built in.

Button names

In general, write the names of buttons exactly as they appear onscreen. If the button’s name uses sentence-style capitalization, enclose the name in quotation marks. If the button’s name uses title-style capitalization, don’t enclose the name in quotation marks, even if one of the words is in lowercase.

Correct: With Photos, you can create slideshows.

colons

Follow these guidelines for using colons:

  • In running text: Capitalize the first word after the colon if the word begins a complete sentence (exception to The Chicago Manual of Style).

There are two ways to raise or lower text in relation to adjacent text: You can make characters superscript or subscript, or you can adjust the baseline shift.

Ordinary video clips and image files have three channels of color information: red, green, and blue.

  • In headings: If you use a colon in a heading, capitalize the first word after the colon, regardless of its part of speech.

Setting up: A beginner’s guide

  • With lists: Precede every list with a colon, whether the sentence before the colon is a complete thought or a partial thought (exception to The Chicago Manual of Style).

command

A command is in a menu, not on a menu; a menu contains commands. Users choose commands; they don’t select commands.

command names

Use title-style capitalization for command names; don’t capitalize command.

the Find command

the Make Alias command

  • Commands used as ordinary verbs: Don’t capitalize a command name when you use the name as a normal English verb.

dash (em)

Use the em dash (—) to set off a word or phrase that interrupts or changes the direction of a sentence or to set off a lengthy list that would otherwise make the syntax of a sentence confusing. Don’t overuse em dashes. If the text being set off doesn’t come at the end of the sentence, use an em dash both before it and after it.

See all your schedules—work, school, and social life—in one app.

To generate an em dash in a word-processing app, press Option-Shift-Hyphen. Close up the em dash with the word before it and the word after it.

dash (en)

The en dash (–) is shorter than an em dash and longer than a hyphen. Use the en dash as follows:

  • Numbers in a range: Use an en dash between numbers that represent the endpoints of a continuous range.

bits 3–17, 2003–2005

  • Compound adjectives: Use an en dash between the elements of a compound adjective when one of those elements is itself two words.

data

Singular or plural, depending on the context. When used as a collective noun, data takes a singular verb. When the meaning isn’t collective, use a plural verb. In user materials, avoid in favor of information if information makes sense in the context.

Collective and thus singular: Data is stored in a FileMaker Pro database.

Not collective and thus plural: Selected data are transferred immediately.

dimensions

In general, use by, not x, to show dimensions.

8.5 by 11 inches, 8.5-by-11-inch paper

Avoid: Make sure virus-protection software and system sleep are disabled.

fair language

Avoid cultural biases and stereotypes, which may offend some users of Apple products. Be aware of the variety of people who are potential Apple customers, and write consciously to include them.

Given name examples: Anton, Avram, Gabrielle, Jim, Luisa, Mei, Sanjiv, Yoshiko

Family name examples: Contreras, Johnson, Kawabata, Meyer, Scharanski, Stern, Wong

Situations: Portray both women and men in a variety of occupations and situations, not just stereotypical ones.

Pronouns: Avoid using gender-specific pronouns generically. When referring to an individual of an unspecified gender, don’t use he, she, he or she, or he/she. First try to rewrite the sentence to avoid the need for a singular pronoun.

Avoid: The student imports his GarageBand composition into iTunes.

In user materials, avoid using native to describe apps; instead, describe the apps as being designed to work with specific hardware or software.

For best performance, use an app designed for use on Intel-based Mac computers.
