What Safari is
Safari is the web browser Apple provides for its own devices, which the company calls “the best way to experience the internet on all your Apple devices.” Its engine is WebKit, and Apple attributes Mac performance and battery advantages to deep WebKit integration with macOS hardware; claims like “the world’s fastest browser” are Apple’s marketing language. The official product page is apple.com/safari.
Usage and boundaries
Safari targets Apple devices: the official page covers tab syncing and Handoff across Mac, iPhone, iPad, and Apple Watch, and there is no Windows or Android version — those platforms need another browser. Features listed on the official page include Intelligent Tracking Prevention (on-device intelligence that blocks cross-site tracking and hides your IP from known trackers), Private Browsing with locked windows, a Privacy Report, plus passkeys, iCloud Keychain, Apple Pay, Tab Groups, Profiles, web apps, and extensions.
Its relationship with the operating system is a defining trait: saved passwords and other sign-in data are managed by Apple’s system keychain (iCloud Keychain), synced across Apple devices, and readable by other browsers on the platform subject to system permissions.
Discussion in the show
In Weekly #003’s chapter “语音输入产品与实时反馈” (“Voice-input products and live feedback”), Yang Pan describes himself as a long-time Safari user: he picked it for its few extensions and its Keychain binding, keeping his passwords in Apple’s keychain. He also mentions Apple splitting the old keychain into Keychain and Passwords, and that Chrome can now read macOS keychain passwords directly — leading him to conclude that “apart from 1Password’s features, Chrome covers the basics on its own.” These are the speaker’s personal experiences and trade-offs; statements about system changes should be checked against Apple’s official documentation.
