Are there any apps on OS X that can block certain websites ('time-wasting ones') for a certain interval?

Preferably works for Safari.

  • It seems like all the options in 2019 / 2020 are paid for services :-( very disappointing when this is possible on Windows and Linux

SelfControl is a free app that will let you enter the websites you want blocked and for how long you want them blocked for.

  • You cannot block facebook.com and allow Whatsapp....really annoying!

WasteNoTime is a good app for this. It is a browser extension.

I'm currently trying Mindful Browsing and I really like it. It's very simple to setup and does the job perfectly.

Check out the website: http://www.mindfulbrowsing.com.

Cold Turkey seems to work quite well and is free (although you have to pay if you want the schedule functionality)


I downloades SelfControl, and while it seems the only option for Safari users, it is a very limited program. You can only block up to 1 day. Unlike programs like stayfocusd, and cold turkey, which allow you to properly schedule blocking times, I might advise you to just switch to using chrome again, there seem to be more well developed programs for that, unfortunately

    you say 'just switch to chrome' but it doesn't stop you from 'just switching to Safari again' when you want to look at facebook

  • You can extend block timer for longer block durations

Blocker for Facebook is available for Safari: https://extensions.apple.com/details/?id=com.devankuleindiren.blockerforfacebook-ZRQ35C78DB

It creates a button that, upon clicking, asks you for how many minutes you'd like to block Facebook. If you go to Facebook, it throws a popup stating Facebook is blocked and redirects you to Google.

  • These seems to be a dead link now
