Just restored an old MacBook Pro and installed chrome and this worked brilliantly. Thanks for allowing me to use chrome once more on a 10 year old laptop that was destined for the trash.

Wow! Very Thankful this worked. I am using a 2008 iMac, now running with OS X 10.11.6 – El Capitan. The exact screens in my Key Chain app were slightly different. Yet using this information I was able to get my ISGR Root X1 certificate to be trusted.

Oh my gosh Thank you! Why do i feel like a computer genius now?

Im on a vintage 2007 iMac and i couldn’t figure out why this was happening to every single site i went to. I couldn’t even look for jobs on Indeed (not complaining, work is trash) which is when i decided to figure this out. My time and date settings were accurate too so i was stumped. Until the sky cleared and Austen descended from “the cloud”.

Thank you so much. Im off to apply for a cyber security job now. Wish me luck!

First of all, thank you so so much! I followed the guide to precision with success. I am on a vintage Macbook (10.11.6 OS X El Capitan). I have gotten this NET::ERR_CERT_DATE_INVALID for every site – in Chrome only though – for year probably a year now since the mentioned certificate expired

Have searched around for solutions, and even tried to recruit something to sort it out. When one applicant told me it had to do with certificates, I decided to search more in detail. I came through great many articles but not until I read this one I solved it

Only one comment though. At least on my Macbook one shall DRAG AND DROP the .pem file into the Keychain Access to actually add it, and not just open it from say desktop. Moreover, to find the Trust down menu I doubled clicked on it, which also were not so apparent, but awesome articles thanks so much!

In reply to Kirsten. At Step 5 in the article, try adding the certificate to the "login" keychain.

Hi I have downloaded and saved the pem file, however I get this An error occurred. Unable to import “ISRG Root X1”.

So wonderful for you to helping so many, any further assistance would be invaluable.

Muchas gracias por toda la información, no me dejaba seguir todos los pasos pero al final pude (no se como) añadirlo como certificado de confianza y el problema está resuelto…

Muchas gracias
