How do I replace an Apple Developer ID Certificate that indicates it is not trusted? When I look at my Certificate Expiring 02-20-2025, I see a valid status displayed. (See annotation #1.) However, when I look at my Apple Developer ID Certificate renewal, I see the words not trusted. (See annotation #2.) I downloaded the renewal certificate and double double-clicked the downloaded item to place it in my KeyChain. This certificate period is from 01-21-2025 to 01-22-2030. QUESTIONS Why does the renewal certificate say "certificate is not trusted"? (Its period is 01-21-2025 to 01-22-2030. Today is 01-27-2025.) How did the renewal certificate get damaged? What must I do to get the damaged certificate replaced with a valid one?

I want to install the Xcode version for macOS 14.6. The App Store shows Xcode 15 with macOS Sonoma. But I want the Xcode version that works with macOS 14.6. At this time, I want to continue using macOS Ventura (14.6), not macOS Sonoma. I navigated to Xcode Resources at https://developer.apple.com/xcode/resources/. Then, I scrolled down to Additional Downloads and clicked the link labeled Command line tools and old version of Xcode. The More Downloads page appears at https://developer.apple.com/download/all/. Once again, I scrolled down to the first Xcode version, following the various Xcode 15 versions. I found Xcode 14.3.1. See the following image. QUESTIONS: Is this the Xcode version I should install to work with macOS Ventura 14.6? What is the extension ".xip"? (See #3 in image above.)
