Q: My Mac mountain lion won't open mail because of pop up blockers

Hey there JKH1114,

It sounds like you are trying to access email at your providers website, but you are prevented from doing so because the Popup Blocker is enabled. You can disable it in the same place this article says you can enable it:

Safari 6 (OS X Mountain Lion): Block pop-ups and unnecessary content

Block pop-ups on webpages

 

1. Open Safari if it is not already open.
2. Choose Safari > Preferences, and then click Security.
3. Turn on “Block pop-up windows.”

Thank you for using Apple Support Communities.

Regards,
