How to block apps on Mac

UPDATED AUGUST 2026 · 6 MIN READ

The Mac is where work happens, which makes it the most expensive place to lose an afternoon. Games, Discord, a chat app that will not stop, the browser itself: here is how to actually block an app on macOS, and why most of the folk remedies do not survive contact with a deadline.

The folk remedies (and why they fail)

• Quitting the app. Reopening it takes one keystroke. This is not a block; it is a pause with extra guilt.
• Removing it from the Dock. Spotlight does not care what is in your Dock.
• Moving it out of Applications. Now the app is both available and disorganized.
• Logging out of the account. You know the password. The login screen is a two-minute delay, not a wall.

The pattern: anything you can undo in under a minute will get undone in a weak minute. A real block needs to not take orders from you while it runs.

Option 1: Screen Time on Mac

macOS Screen Time can put daily limits on apps:

1. Open System Settings → Screen Time.
2. Choose App Limits, click to add one, and pick an app or a whole category.
3. Set the daily allowance and save.

When the allowance runs out, the app greys out with a "limit reached" screen. And on that screen sits the problem: an ignore option that grants more time in a click or two. You set the limit, you know the passcode, so the limit binds nobody. It works as designed for parents managing kids; it structurally cannot work as self-discipline. More on that in why Screen Time limits don't work.

Option 2: A blocker with sessions and teeth

bloq approaches Mac app blocking the way it should work for adults blocking themselves:

1. Build a block list. Pick the Mac apps (and websites - the browser side is covered too, system-wide) that eat your time.
2. Start a focus session. For the length of the session, opening a blocked app bounces you back to bloq. No allowance, no ignore button.
3. Or set a daily limit. 30 minutes of the app means 30 minutes; after that it is blocked until midnight. Time counts while the app is actually in front of you.
4. Schedule it. Sessions can start themselves every workday at 9am, so the decision is made once, not every morning.
5. Turn on Super Strict Mode when you mean it. A super strict session cannot be paused, stopped or edited, and the app itself cannot be deleted, until the timer runs out.

The two-device problem

Block an app on the Mac and the same feed is waiting on the phone in your pocket. Any serious setup covers both. bloq syncs sessions, schedules and block lists across Mac and iPhone through your account: start a session on either device and both lock together, end it and both open together. The Mac block without the phone block just moves the scrolling eighteen inches to the right.

FAQ

Can I block an app on Mac without extra software?

Screen Time App Limits are built in and free. They cap daily use rather than blocking outright, and the person who set the limit can always click through it - fine for managing kids, weak for managing yourself.

Can I block Mac apps only during work hours?

Yes. bloq schedules start and end sessions automatically, per block list, so games can be locked 9 to 5 while the tools you need stay open.

What if I try to quit or delete the blocker?

With Super Strict Mode running, bloq keeps the session alive: you cannot stop it early, edit the block list, or delete the app until the timer completes.

Does blocking an app on Mac block it on iPhone too?

With bloq, yes - sessions sync both ways, so one start locks both devices.
