Speed Up A Slow Mac. We live in a fast-paced world and anything that slows us down can cause a lot of frustration. For Mac PC users, nothing contributes to this frustration more than a slow PC. We’ve come to rely heavily on our digital technology and we use them for so many daily assignments and activates. Test your internet speed. If you keep asking yourself how to speed up your internet, first of all, test. Try a different Internet connection. Test your Internet connection by streaming a video from. I deleted my vpn (Fast. vpn) from the mac applications folder and re-run the test and yes, it did work! I have pulse secure on another machine but unfortunately, pulse secure on my other machine is for work. I can't just delete it as connecting back to office. Download speed was from 29 and went up to 104. Upload speed from 18 went up to 283.
(First, if yours is an Intel Mac, check that Safari is not running in Rosetta, which is enough to slow it to a crawl.)
Adding DNS codes to your Network Settings, should gives good results in terms of speed-up:
Open System Preferences/Network. Double click on your connection type, or select it in the drop-down menu. Click on TCP/IP and in the box marked 'DNS Servers' enter the following two numbers:
208.67.222.222
208.67.220.220
(An explanation of why that is both safe and a good idea can be read here: http://www.labnol.org/internet/tools/opendsn-what-is-opendns-why-required-2/2587 / )
Whilst in System Preferences/Network you should also turn off 'IPv6' in your preference pane, as otherwise you may not get the full speed benefit (the DNS resolver will default to making SRV queries). If you want to know what IPv6 is:
This is Apple's guidance on iPv6:

Click on Apply Now and close the window.
Restart Safari, and repair permissions.
If that didn't do it, then try this as well:
Empty Safari's cache (from the Safari menu), then close Safari.
Go to Home/Library/Safari and delete the following files:
form values
download.plist
Then go to Home/Library/Preferences and delete
com.apple.Safari.plist
Repair permissions (in Disk Utility).
Start up Safari again, and things should have improved.
