Slow internet connection on my Mac Mini Starting yesterday I'm dealing with low internet speed on my Mac; my download rate is 40 KB/S at the max. while my default download rate is 100 KB/S. I shut down my mac and tried another two PCs; the speed is my default and browsing is normal and I didn't encounter any slowness in my connection. So, I figured that the problem is on my Mac whether there's an application running update in the background or the App store updating (but the app store contains no update).

I need your help to find a way to track my internet usage so I may be able to terminate the problem.
Access Spotlight - either with cmd + spacebar or by clicking the magnifying icon on the right top corner of your screen
Search for Activity Monitor.
Select the far-right tab titled Network and you will find a description of all the network processes going on on your machine.


If there's a high network consumption process, you'll be able to spot it.
