Why are there untrusted certificates in the system keychain on my Mac?

It's always the folks who aren't tech-savvy who seem to get anxious about these warnings. But here's the thing: questioning and asking is how you learn. If someone doesn't understand something, they should definitely ask for clarification. That's the best way to gain some knowledge!

Honestly, it's typical for new users to wonder about these things. The 'not trusted' labels are just Apple's way of indicating that certain certificates are outdated or potentially risky. It's their method of maintaining security, and nothing you've mentioned should raise any alarms. Just keep asking questions and you'll get the hang of it!

You don’t need to stress about those untrusted certificates; it's pretty normal. Most Macs will have similar certificates, and they're managed by Apple through software updates—not by users. Those marked as 'not trusted' might be expired, deprecated, or intentionally kept around for reference. It’s all part of how macOS keeps your system secure, so it sounds like you’re in the clear!
