If a certificate being used for a connection is expired or invalid, then OS X will notify you of this when attempting to use it, and offer you the choice of continuing with the connection, inspecting the certificate, or canceling the connection.

Such warnings are convenient for detecting an invalid connection, such as one that might be malicious, so if they happen then consider looking into them; however, there may be times when practically every connection you attempt gives you a certificate warning.

When this happens, it suggests a problem with your certificate configuration, more than a problem with the connections at hand, and this may happen for several reasons, which can usually be fixed by one of the following approaches:. Check your date and time. Be sure the time server used is one that is appropriate for your location, and then close the system preferences. Within a few moments, OS X should adjust your system clock, which should clear the certificate errors.

You can ensure this is always the case by using a dedicated time server for your system. If this is happening only for specific certificates, and you trust that the service you are connecting to, then you can modify the trust settings for the certificate to allow the authentication to proceed.

In here, click the Certificates category, and then locate the certificate for the service you are connecting to. You can do this by searching for the domain name of the service, or by sorting the certificates by name and scrolling through them. In these cases, you can right-click the certificate and remove it from your system. If the connection requires one, then it will be downloaded from the service again the next time you connect and authenticate.

Start by choosing this option to remove custom trust settings for your certificate, but also consider adjusting specific trust settings that pertain to your connection. If the certificate has a blue plus symbol, then this indicates custom trust settings for the certificate, which may be the reason for the faults you are experiencing.

For instance, a certificate may be used for SSL validation, but if this trust setting is not set up properly, then OS X will prompt you to use this certificate every time an SSL connection attempts to use it. Fixing this requires adjustment of the trust settings for the certificate:. The system defaults setting should have the certificate used for the appropriate connections on demand; however, you can also attempt to manually adjust the custom trust settings for the certificate. You can try similar options for the other trust settings, but only enable those that the certificate is specifically used for.

While you should not need to clear your entire keychain and set it up from scratch again, you can select and remove the certificates that are mentioned by these errors. Doing so will have the system re-download new certificates for connections that demand them, potentially overcome configuration errors in the prior certificates.
