Endless Blocks Mac OS

Posted on  by

Hello Friends,In this tutorial, I will show you how to install and setup code blocks on mac os x Catalina to run C/C program. I have explained the whole pr. Upon a successful os upgrade and H&R Block install, my first running of the H&R application crashed. Fortunately the next run of it did not crash and I was able to select a download and upgrade of H&R Block code. I hope this is the end of the H&R Block 2020 problems, and that I don't have to switch to using a PC or using TurboTax next year.

There are many ways to blocks unwanted websites on a Mac OS X. The first that comes into your mind might be the Mac built-in parental controls, which is perfectly easy to be done. Likewise, there are many methods to bypass the built-in parental controls. Only making use of the built-in parental controls is not far enough for your tech savvy child. Here, I will introduce several other free ways to block unwanted content on a Mac OS X.

2. In this Add-ons page, search for 'BlockSite'. Click 'Install' to continue installation. It will look like below:

3. Click 'Restart now' to finalize the installation process.

4. Go to 'My Add-ons' and click 'Preferences' to load the options.

6. Click 'Add' and then type in a website URL. Repeat this process with all websites that you want to block in Firefox. Then click 'OK' to save changes. If you set up a password, you will be prompted to enter it every time you try to change the 'BlockSite' details.

7. Add the URLs and names of the websites that you want to block in the 'Blocked URLs' box, and then click 'Save URL'.

There are many options in Chrome Nanny. You can set it according to your own choices.

Notice: Browser like FireFox or Google Chrome has its own add-ons or extensions to block sites. However, no one works with Safari or the whole Mac system. Mac OS X has Hosts file just like Windows. We can also edit Hosts via Terminal on a Mac to block specific websites that you don't want to be accessed. Not only does it work in Safari, but also it works with the whole Mac system.

◆ Use Terminal to Block Websites on Mac

1. Click the 'Finder,' select 'Applications,' choose the 'Utilities' folder and click 'Terminal.'
2. Type 'cp /etc/hosts ~/Desktop/hosts.txt' (without the quotes) to copy your current hosts.txt file to the desktop as backup.
3. Type 'sudo pico /etc/hosts'.
4. Enter your Macintosh administrator password and press 'Enter.'
5. Use the arrow key to move the block cursor down to the bottom of the file and enter the IP address '127.0.0.1' followed by the domain name you want to block. This tells the computer that the address for that domain is now that IP number 127.0.0.1, which is your local Macintosh, and the browser won't be able to resolve that domain to a Web page.

6. Press 'Ctrl-X' to exit after you have entered all the domains you wish to block. The domains need to be on separate lines. You will be prompted to save. Press 'Y' for Yes.
7. Please run the following command in Terminal to take the changes take into effect:
①If you are using Mac OS 10.4.X, please type the following and press Enter:
lookupd –flushcache
②For Mac OS 10.5.X and later, it can be done by entering the following and press Enter:
sudo dscacheutil –flushcache

8. Click the Terminal menu and select Quit Terminal to exit.
9. Open Safari and type in the domains you blocked in the hosts file. All other browsers on your machine will be blocked from accessing that domain as well. You can enter as many domains as you want into the hosts file, but put each command on a new line and remember this action blocks them from all users of the computer, including you.

We can block any sites we don't allow to on Mac by modifying the host file. However, we do not recommend this way if you are not proficient at Mac.

Most of the ways above can only block site one by one. If you want to block porn content in large scale, such as blocking sites by keywords, you may need a professional filter, like the xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx Mac website blocker xxxx. It has more options then free ways and It is quite easy to use.

To use a keyboard shortcut, press and hold one or more modifier keys and then press the last key of the shortcut. For example, to use Command-C (copy), press and hold the Command key, then the C key, then release both keys. Mac menus and keyboards often use symbols for certain keys, including modifier keys:


On keyboards made for Windows PCs, use the Alt key instead of Option, and the Windows logo key instead of Command.

Some keys on some Apple keyboards have special symbols and functions, such as for display brightness , keyboard brightness , Mission Control, and more. If these functions aren't available on your keyboard, you might be able to reproduce some of them by creating your own keyboard shortcuts. To use these keys as F1, F2, F3, or other standard function keys, combine them with the Fn key.
