1. Introduction: The Shock of the "Last Intel Mac Compatible OS" Declaration

At the Platform State of the Union at WWDC 25, Apple explicitly stated that "macOS Tahoe will be the last release to support Intel Macs." This means the company's CPU transition plan, initially set for "two years," will effectively be completed over five years.

2. The "Last Four Models" and the End of Support Schedule

Only the following four Intel Mac models can install macOS Tahoe. 

Apple has stated that it will provide "important security updates" for these four models until the fall of 2028, but no additional features will be added. 

3. Five-Year History of Apple Silicon Transition—Why "Complete Transition" Now?

• Performance/Power Efficiency Gap: Since the introduction of the M1, Apple Silicon has continued to significantly improve in performance/power efficiency compared to the same generation of Intel.

• SoC Integration and Neural Engine: The Neural Engine, which processes generative AI functions quickly on-device, is exclusive to Apple Silicon.

• Optimization of Development Resources: Balancing optimizations for both x86 and Arm was costly, and early convergence was desirable.

4. Key New Features of macOS Tahoe and Limitations on Intel Mac

UI/UX updates such as full transparency of the menu bar with Liquid Glass and direct action execution in Spotlight can be enjoyed on Intel Macs. However, features related to generative AI require the Neural Engine, resulting in them being grayed out on Intel Macs. 

5. The Implication of Non-support for Apple Intelligence on User Experience

Apple Intelligence is a generative AI platform spanning iOS, iPadOS, and macOS, central to advanced features like text generation, image generation, and Live Translation. The inability to run these on Intel Macs creates not a **“feature gap” but a “worldview divide.”**

6. The Fade-out of Rosetta 2 and the Roadmap for Developers

Apple has hinted that "macOS 27 will not assume the use of Rosetta 2," urging developers to fully transition to Arm-native apps.As a result, the "life support" for x86 binaries is expected to come to an end in 2026.

7. Security updates until 2028—Risks thereafter

After the end of patch support for Intel Macs, the risk of exposure to zero-day vulnerabilities will sharply increase. Especially for models equipped with the T2 chip, firmware updates related to the secure enclave will also cease, potentially expanding the risk of data leakage in the event of physical theft or malware intrusion.

8. Four Strategies for Intel Mac Users

9. Challenges and Solutions Faced by Enterprises and Educational Institutions

1. Asset Management

   • Set EoS Flags for Intel Devices with MDM like Jamf Pro and Share Update Plans.
     
     

2. Business Application Compatibility

   • Virtualize Unsupported Apps with Parallels Desktop or Transition to DaaS.
     
     

3. Training Costs

   • Swift 6, Metal 4, and Core ML 4 onsite training to be conducted ahead of schedule.
     
     

4. Security Operations

   • From 2028 onwards, third-party EDR will replace patches, and a Zero Trust model will be introduced.

10. Conclusion—The Final Chapter of Intel Mac, Looking Ahead

macOS Tahoe is not just an OS update.It is a declaration of the complete transition of the Apple platform to a "Neural Engine-first" approach, positioning the remaining Intel Macs as legacy assets. Users who have hesitated to upgrade should reconsider their transition plans now, as the shift to Arm-native apps accelerates. The decision to transition to Apple Silicon should realistically be based on three key points: (1) compatibility of necessary apps, (2) support status of peripherals, and (3) return on investment. View the end of the Intel Mac era as the "last chance" and make a forward-thinking choice.
