How to access a website despite a certificate error?
For Google Chrome the following flag exists to circumvent certificate errors and continue browsing:


Close Google Chrome
Open Terminal and enter:

/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --ignore-certificate-errors &amp;&gt; /dev/null &amp;


If the app resides somewhere else than in /Applications/ apply the path to Google Chrome respectively.


Launching Google Chrome like this is rather meant for dev purposes than for normal browsing since the security of the https-connection(s) is flawed.
