You install a website blocker extension in Chrome. It works — for about a day, until you subconsciously open Safari instead, where the extension doesn't exist, and the site loads without friction. You didn't even mean to circumvent it; your Mac just has more than one browser, and the blocker only knew about one of them.
This is the most common failure mode for browser-extension blockers. They're scoped to a single browser by design, and switching browsers takes less effort than most people realize.
Почему расширение блокировщиков утечек
A browser extension can only see and control traffic inside the browser that hosts it. If you have Chrome, Safari, Firefox, and Arc all installed — which is common on a Mac — an extension in one leaves the other three completely open. Some people don't even realize they have multiple browsers until they're actively looking for a way around a block, at which point their brain finds Safari's dock icon remarkably fast.
Extensions are also easy to disable in a few clicks from the browser's own settings, which defeats the purpose the moment you have a bad afternoon.
Вместо этого блокировать на системном уровне
Lock In! uses a macOS network extension rather than a browser add-on, so the block applies below all browsers at once — Safari, Chrome, Firefox, Arc, Brave, and anything else installed on the machine.
Один блок, каждый браузер
Add a domain once and it's blocked everywhere on the Mac, immediately. There's no per-browser setup, no separate extension to install four times, and no browser you forgot to cover.
Нет расширения для отключения во время сеанса
Because the block runs at the system level rather than inside a browser, there's no extension toggle to switch off when motivation dips. Строгий режим goes a step further, making the entire session uncancellable until the timer ends.
Предустановленные списки для очевидных виновников
Social, Entertainment, News, and Shopping presets cover the most common distraction categories out of the box, so there's no need to hunt down and manually enter dozens of domains across every service you want blocked.
