[QUOTE="MacInWin, post: 1839797, member: 396914"] @MBAmtloin, the certificates are not an inherent part of OS X or macOS. Rather, the certificates are from independent third party certifiers that issue certificates to verify who issued the software, or the website. Here is a quick definition: [url=https://www.techopedia.com/definition/5607/security-certificate]What is a Security Certificate? - Definition from Techopedia[/url] When the installer starts up, it goes to the certificate issuer to see if the certificate is valid. If not, the installer won't run. Apple could have elected to have the user be able to override the invalid certificate, but they chose the more secure method of blocking execution. So if you download a fresh version of ElCap from the App Store today, the certificate will be current and valid, at least for a while. Certificates can last a long time, and I have read elsewhere that current certificates from Apple are good until 2029. I'm not one of those who hold back from updates. ML was good, but the security of later versions was significantly increased. I guess it's a bit like when I occasionally see old cars and think, "Wow, what a machine that was! Love to have one." But then reality sets in when I get in my new(er) car with GPS, stereo, smoother transmission, fewer maintenance issues, better gas mileage, more comfortable ride, etc, etc, etc, and the attraction of that older car diminishes. Romance over old stuff is OK, but for day-to-day, give me modern every time. [/QUOTE]
