Using mac isn't a problem because I am using a mac as well, not having a single issue.

Have you tried another browser? Also why not add the IP to your host file and then flush your dns

Open terminal:
Accessing the host file
Code: 
sudo nano /etc/hosts
Scroll all the way down after the last line and paste this
Code: 
108.61.8.195 besthostingforums.com
108.61.8.195 www.besthostingforums.com
And then
Code: 
press ctrl+o [enter] and then ctrl+x
After that you need to flush DNS
If you are using an osx that is older than lion
Code: 
dscachutil -flushcache
For lion and mountain lion
Code: 
sudo killall -HUP mDNSResponder
Then restart your browser and try, hope it works then (:
