I have Three Macs. One in Office, one in home and one which I use for travel. All three have different OSX versions, 10.10, 10.9 and 10.7 respectively. The oldest one one 10.7 has 1Password 3 and I am unable to install 1Password for Chrome extension. When I install the extension I get a red warning icon which simply does not go away. When I enter password, it shows connecting... I have tried re-installing the extension, chrome but it does not help at all.
p.s: The extension works fine on Firefox.
