Can't access WordPress admin login

I have about 10 sites and while I am on my imac I get a cookie error that says this, The requested URL /cookies.html?backurl=http://bryant-dodd.com/wp-login.php?redirect_to=http%3A%2F%2Fbryant-dodd.com%2Fwp-admin%2F&reauth=1&ckattempt=3 was not found on this server. That’s all we know.
It says this for all my sites in safari, firefox, chrome. The strange thing is, I can login to my admin at work on a pc. That tells me maybe it is a issue on my imac side. I cleared cookies and full clean up on mac but still same issue.
Anyone else had this problem? I changed htaccess, replaced wp-login file, and web host can login.
