Cannot launch admin console on website

Works on my laptop, so issue resolved I guess. I tried two different browsers, Firefox and Safari on my mac, neither worked.

Can you get to the website with your MAC?
If not are you using a VPN, we block many VPN because hackers love them.

Still the same issue - I can get to the website and even log in using password. But I cannot launch the admin console to get in and make changes. This is a problem I just started having with my desktop mac. I don't have this problem with my macbook pro. 
Thanks for any suggestions. 

Have you tried clearing your browser cache, or clicking the reload link at the bottom of your site?
Are you logging in with the ADMIN user and password? not you personal login?
Can you tell us more about your MAC what version of OSX?
What Browser and version are you using?
Are there any errors that pop up?
