How to increase upload speed on Mac

Slow internet connections can often be caused by issues with your router; here's how to troubleshoot:

  • Check that your router is working correctly.

  • Reboot your router.

  • Check for overheating.

  • Check that all cables are connected.

  • Reposition your router.

3. Optimize your Mac performance

Slow Mac=slow everything. If your Mac isn't operating at its best, you can't expect your internet to be much better. 

I recommend freeing up RAM (random access memory) to help speed up your macOS and running some maintenance scripts which clear up temporary items and rotate logs. You could do this manually, but you will need some time and patience; that's why I prefer to use a tool like CleanMyMac X to do all the hard work for me.
