How To Limit Download And Upload Speed On Mac


If you share your Internet with someone on your Mac and are bugged by the fact that the other person consumes all your bandwidth, then there is a way to limit download and upload speed on Mac.

You can set the download and upload speed to as lower value as possible and I am sure that the other person would be disappointed by the speed of your Internet connection and might stop using it. And even he does not, the super slow download speed will save a lot of your bandwidth.

This is a great way to restrict download speed on Mac which would help you save a lot of your Internet bandwidth. For an instance, if you use torrents and worried about the fact that it would suck all the Internet speed and leave no room for smooth browsing, then try these methods to improve the browsing speed.

We would be sharing two methods (one manual and one using a tool), which would help you limit download speed on Mac. Yes, that would limit the upload speed too.

Methods To Limit Download And Upload Speed On Mac

Manual Method

In this method, we would be using few commands on terminal in order to restrict speed. First, fire the below command:

sudo ipfw pipe 1 config bw 20KByte/s

This will create a pipe named, 1 which will restrict the Internet usage to 20Kbs/s.

And then fire the below command:

sudo ipfw add 1 pipe 1 src-port 80

And the above command will add the pipe 1 to port 80, which would be handing all the outstanding traffic ensuring that speed is restricted to 20kbps.

Once you are done, you can remove this setting by removing the pipe that you have created by the below command:

sudo ipfw delete 1

I have tried it, and it works like charm.

Use A Tool – Entonnoir

Entonnoir is a free tool which would help you to do the same that above manual method did for you. Once you download and install this free Mac app, things are completely simplified.

You can limit the web and sftp speeds just by entering the values and enabling it. That is it!

And once you are done, you can simply disable it to revert it back. I bet if there is a simpler way to restrict / limit download speed on Mac.

You can go with any of the above methods to get your task done. Try them and let us know how they worked for you.
