The End of an Era: Intel Mac Transition Guide for macOS Tahoe and Beyond

After nearly two decades of Intel-powered Macs, Apple is completing its transition to Apple Silicon with macOS Tahoe (macOS 26) marking the final chapter for Intel Mac support. This comprehensive guide helps Intel Mac users understand their options, plan their transition, and make informed decisions about their computing future.

The Intel Mac Era Comes to an End

A Historic Transition

Apple's relationship with Intel processors began in 2006 with the transition from PowerPC, revolutionizing Mac performance and compatibility. However, as Apple's custom silicon technology matured, the company began the transition back to its own processors in 2020 with the M1 chip.

Key Milestones:

• 2006: First Intel Macs launched
• 2020: M1 Macs introduced, Intel transition begins
• 2023: Last Intel Mac (Mac Pro) discontinued
• 2025: macOS Tahoe - final Intel support
• 2026: macOS 27 - Apple Silicon only

What macOS Tahoe Means for Intel Macs

macOS Tahoe (macOS 26) represents the end of the line for Intel Mac users:

Final Intel Support:

• Last macOS version to support Intel processors
