SelfControl

Using your computer to work can be really hard. You have access to Facebook, Twitter, YouTube, and millions of time-wasting websites. If your goal is to write, study or anything else that requires a computer, then you might need a little help to keep you away from certain websites.
You might need SelfControl. I’m talking about an app, although having your own self-control is also pretty important.
SelfControl is an app exclusive to Mac that blocks websites for a certain amount of time. You have to put these websites yourself on a blacklist. Once you start the timer, there’s nothing you can do to access those sites. Even if you restart your Mac or even delete the app.
This app, though, can only be installed outside of the App Store. If you don’t trust apps like this one, then you can try the 1Focus app. It basically works the same as SelfControl and it’s available on the App Store.
