Apple has officially ended software support for its remaining Intel-based Mac computers and several Apple Watch models. This decision follows the release of macOS 27 Golden Gate and the AI-focused watchOS 27.

The final four Intel Mac models losing macOS 27 support

The transition to Apple Silicon is reaching its conclusion as Apple retires the last of its Intel-powered computers. according to the report, the specific machines losing access to the latest operating system include the 2019 16-inch MacBook Pro, the 2020 13-inch MacBook Pro, the 2020 27-inch iMac, and the 2019 Mac Pro.

These devices represent a significant portion of Apple's former professional ecosystem. For example, the 2019 Mac Pro, which carried a starting price of $5,999, served as a high-end workstation for industries like 3D rendering and film production. Similarly, the 16-inch MacBook Pro, retailing from $2,399, was a flagship for creative professionals.

How watchOS 27's AI features are driving hardware obsolescence

The rollout of watchOS 27 is the primary catalyst for the sudden loss of support for several Apple Watch models. This new operating system is heavily centered on artificial intelligence, introducing advanced capabilities such as an AI "Workout Buddy," improved Siri AI, and hand gesture tracking.

As the report indicates, these AI-driven features demand intense processing power that older chips simply cannot provide. Consequently, users will be unable to access new software tools, including a specialized app designed for perimenopause and menopause support, unless they own newer hardware.

The confusion over which six Apple Watch models are obsolete

There is a notable discrepancy in the reporting regarding exactly which Apple Watch devices are being retired. while the source states that Apple has dropped support for "five popular Apple Watch models," the subsequent list actually names six distinct devices: the Apple Watch Ultra 3, Ultra 2, Series 11, Series 10, Series 9, and the SE 3.

It remains unclear whether the report contains a clerical error or if Apple is treating one of these models differently. this leaves owners of these relatively recent devices—some released only four years ago—uncertain about their future ability to receive security updates and new features.

A mandatory shift toward M1 chips and Apple Silicon

Apple's move to its own proprietary silicon has fundamentally redefined the requirements for the Mac lineup. To access future software updates and features, users must now utilize a Mac equipped with an M1 chip or a more recent version.

This shift aims to provide users with dramatically improved battery life and higher performance compared to the legacy Intel architecture.. However, as the report notes, this transition effectively freezes the utility of older, expensive machines that are no longer eligible for major macOS upgrades.
