1Password 5 not working properly with Chrome on iMac after OSX NTP Security Update

Community Member

I am using a iMac 27inches late 2012
OSX Yosemite 10.10.1
1Password extension
Chrome 39.0.2171.95 (64 bits)

I started having funny problems with 1Password on Chrome after the OSX NTP Security Update on the 23-Dec 2014.

However, when using Safari 8.0.2 the iPassword extension 4.2.5 is working perfectly.

Previously, before the NTP Update, the 1Password mini was also working perfectly with Chrome for few months since August 2014.

Pls help to advise how to overcome this problem.

    Hi @lpwlpw3983‌,

    Thanks for taking the time to write to us :smile:

    I just applied the OSX NTP Security Update last week and I am using Chrome 39.0.2171.95 (64 bits) along with the latest stable 1Password Browser Extension and everything works fine.

    1Password mini communicates with browser extensions via web sockets. There are several factors that can "break" this communication such as the OS X firewall, other firewall apps, antivirus apps, etc. Please make sure that nothing is blocking the connection to local host (

    Let's try and reboot your Mac and see if this solves the problem. If not, please send us a Diagnostics Report from your Mac, along with a link to this topic and your forum username, to support+forum@agilebits.com.  A brief comment here mentioning that you've sent the report would also be helpful.

    Once we see the report we'll be able to better assist you.

    Thanks in advance!
