You then need to type "sudo dscacheutil -flushcache" and hit Enter to apply the changes.This study investigates prevailing restrictions on Internet diffusion through blocking of websites across five categories in diverse country domains. As on Windows, you can then add new websites to the end of the file, one site per line, using the format "127.0.0.1 Ctrl+O will save the file, and Ctrl+X will exit it. Type "sudo nano /etc/hosts" and hit Enter, then enter your macOS account password to open the hosts file. Under the last line, enter "127.0.0.1" followed by a space, then the URL of a website (without the HTTPS)-add new lines for each of the websites you want to block, save the file, and then restart your computer to see that your chosen sites are no longer accessible.
On Windows, launch Notepad, and then open the hosts file from the Windows/ System32/ drivers/etc folder on your hard drive.
We're talking about editing the hosts file, the file that your computer uses to find its way across the web. It's not foolproof, because you can just undo the changes if you want, but it involves a bit of extra work and may be enough to put you off visiting those sites you know you shouldn't. There is a baked-in way of blocking websites on Windows and macOS that lets you manually stop certain websites from loading-no fee and no extra software required. You can use Cold Turkey for free or pay a one-off fee of $39 for a Pro license and some useful extras, including scheduled blocks, timers to help you work in focused bursts of attention, password protection for the app settings, and a Frozen Turkey mode that locks you out of Windows or macOS entirely-forcing you to go do something other than stare at your screen. (There is a less strict mode that allows you to break blocks if you really want to). It's a comprehensive package, and it also keeps statistics so you can see how many times you've tried to access blocked websites. Once a block is applied, it really is applied-you can even disable access to the Task Manager (Windows) or Activity Monitor (macOS), as well as the Cold Turkey uninstaller, to make sure you stay focused and away from the sites you don't want to see.
You can block certain sites, the entire internet, the entire internet except for certain websites, and even particular Google searches that you don't want to run.
Cold Turkey is a desktop app for Windows and macOS (with accompanying browser add-ons) that don't mess around when it comes to blocking websites.
