DST Root CA X3 expired on Mac is an error that many Mac users have likely started seeing in their browser since the 30th of September. The DST Root CA X3 expired on Mac error prevents users from visiting sites that use Let’s Encrypt certificates.

Recently, many Mac users have started reporting the same problem with their browsers, namely, the appearance of an error message while trying to visit certain sites. The error message shown may vary – “DST Root CA X3 expired” is only one possible error message. Another one is “Your connection is not private” or “Attackers might be trying to steal your information”. Though the error/warning messages that get shown in the browser may differ, the underlying issue stays the same and that is the recent expiration of the widespread DST Root CA X3 certificate, created by the non-profit organization Let’s Encrypt. Many popular sites use this certificate and once it has expired, some (not all) users stopped being able to visit those sites.

There are a couple of solutions for users of older MACs. One is to stop using Safari or Chrome and download Firefox and use it as your default browser. You may also search for a fix for this issue to download and install the "root certificate" - this is something you may want to get a computer professional to do for you. Search for the phrase"DST Root CA X3 expired Mac". Please note we cannot verify the safety or security of any external website, so procedding with this is at your own riskand comes with no guarantees.

You can try installing Firefox as your browser, it does not use the MAC OS built-i root certificate.

The other option is to upgrade your MAC operation system, and if that is not possible, upgrade to a newer MAC.

Have you ever wondered if there's a solution to the ever-dropping Wi-Fi signal in your home? Do you have dead spots where the signal won't reach, such as the basement, the attic or the garage? Using a mesh router may help.

Mesh routers are the latest technology upgrade for home Wi-Fi networks. Mesh networks have been used for years in large places where a secure network is critical, like military bases and businesses. (In such cases, the network is often isolated and not connected to the internet.) Now, residential wireless-internet users can optimize their home Wi-Fi with a form of mesh networking, too.

If you have a large home — at least 3,000 square feet — or one with an unusual layout, more than two stories or interior brick walls, you probably regularly encounter Wi-Fi dead zones, and your setup could be a good candidate for a mesh-router system.

Call our Sales Office to talk about our Command Centre Plus mesh options that we can provide for you.

•  Make sure that your wireless connectivity is enabled on your device.  If you are still unable to connect to the wireless network, contact technical support.
• Make sure your router is turned on.

We offer some protection by stripping away email from known mail servers used to send out virus and exploitive emails and other malware. We cannot protect our customers from viruses that hide in web sites and that are unknowingly attached to mail from legitimate senders. It is the responsibility of all users of the Internet to make sure that they have adequate safeguards in place including the use of firewalls and up to date anti-virus software. Using complicated passwords, staying up to date on software releases, avoiding some websites altogether, and having a good backup are other important items in your arsenal.
