How to remove m86 or 8e6 web filter from school computers, specifically macs, but may also work similarly with pcs. Removing the webfilter will allow you to get on blocked websites at home etc. but will still be blocked by the firewall at school, work, etc. This video was made by me. Please leave feedback if you try it.

scroll down to Apple osx
download the "Tor Browser Bundle for OS X Intel (beta version)"
open it when it's done downloading
it should connect and open a fake firefox after a few seconds
go to any website you want now
