TikTok is the most effective attention trap ever built. Its algorithm learns what keeps you watching and serves an infinite stream of it. Opening TikTok "for just a second" during work is like eating one chip from a bag engineered to make you finish it.
On your phone, you can delete the app or use iOS Screen Time. But on your Mac, tiktok.com is always one tab away. And macOS doesn't give you a simple way to block it.
Why TikTok on Mac Is Especially Dangerous
On your phone, TikTok at least feels like a separate activity — you physically pick up a different device. On your Mac, it's the same browser you work in. You're writing a report in one tab, and TikTok is a Cmd+T away. There's no context switch, no friction, nothing to make your brain register that you've left work mode.
TikTok's web version is fully featured now. The For You page works identically. The algorithm is just as sticky. And unlike your phone, your Mac has a bigger screen and a keyboard — you can fall even deeper into comment sections and searches.
Block TikTok System-Wide with Lock In!
Lock In! blocks tiktok.com at the system level using a macOS network extension. It doesn't matter which browser you use — Safari, Chrome, Firefox, Arc — TikTok won't load during your focus session.
Add TikTok to Your Blocklist
Lock In! includes a Social Media preset blocklist that covers TikTok, Instagram, Twitter, Facebook, and more. Enable the preset or add tiktok.com as a custom entry — either way, one click blocks it for the duration of your session.
Strict Mode for Zero Exceptions
Knowing you can cancel a block and open TikTok undermines the entire point. Enable Strict Mode and the block becomes permanent until the timer runs out. There's no override, no emergency button, no "just five minutes." You set the session length, and TikTok stays blocked for all of it.
Pair It with App Blocking
If you have a TikTok desktop app or use a wrapper like Unite, Lock In! can block those too. Its app-blocking feature shows a full-screen interrupt panel when you try to launch a blocked app, so every path to TikTok is shut down.
The algorithm doesn't sleep, so your blocker shouldn't have loopholes. Get Lock In! on the Mac App Store
