Configuration of trust for root certificates

Go to "Applications"

Find the search icon and click on it:

Type Keychain access in the search

Open the keychain

In the left sidebar of the application window, select "Login", and at the top in the "Categories" field, select "Certificates".
In some cases, the certificate does not indicate a red cross, check the certificate by opening it with a double click!

Open the certificate "Ұлттық куәландырушы орталық (RSA) 2022" by double-tapping. Click on the triangular icon to the left of the "Trust" label, and the list will open. Click on the drop-down list to the right of the item "Standard X.509 Algorithm" and specify "Always trust".

Close the certificate window, after which the system will ask you to confirm your actions by entering a password. Enter the password and click * "Update settings"*.

Then, open the certificate "Негізгі куәландырушы орталық (RSA)" by double-clicking. Click on the triangular icon to the left of the "Trust" label, and the list will open. Click on the drop-down list to the right of the item "Standard X.509 Algorithm" and specify "Always trust".

Close the certificate window, enter the password and click "Update settings".
