Apple's Intel Mac era concludes with macOS update

Apple's transition away from Intel processors marks the end of an era, with the upcoming macOS release serving as the final chapter for Intel-based Macs. This shift concludes a 20-year partnership that initially revitalized the Mac line but eventually faced challenges. Apple began developing an internal Intel-compatible OS, codenamed 'Marklar,' in the early 2000s due to PowerPC chip limitations. The public switch occurred in 2005, enabling Macs to leverage Intel's advancements until Apple's own silicon offered superior performance and efficiency, leading to the current Apple Silicon architecture.
