The encryption system wants to check whether a digital certificate that validates the integrity of a piece of software hasn’t yet expired. If the date embedded in the certificate is before the issuance date or after the expiration date, the software rightly balks—and macOS unfortunately spits out an error, as this eventuality wasn’t considered as far back as Mojave. (The problem may have been fixed since.)</p><p class="jumpTag"><a href="/article/3597997/how-to-fix-the-untrustedcerttitle-error-when-reinstalling-macos.html#jump">To read this article in full, please click here[/url]</p></section></article>
