### macOS 27 to Exclude Intel Macs: Compatibility Restricted to Apple Silicon Models

macOS 27 is anticipated to be revealed at WWDC in a few weeks, signifying a major shift for Apple as it will be the inaugural macOS version solely for Apple silicon Macs. This change follows Apple’s earlier announcement that macOS Tahoe would be the final iteration compatible with Intel Macs.

#### Models Losing Support

Apple has verified that the following four Intel Mac models will be incompatible with macOS 27:

– MacBook Pro (16‑inch, 2019)
– MacBook Pro (13‑inch, 2020, Four Thunderbolt 3 ports)
– iMac (2020)
– Mac Pro (2019)

These models represent the final Intel variations currently supported by macOS Tahoe and will be unable to install the new software upon the release of macOS 27.

#### Future Compatibility

It is improbable that any additional models will lose support, as macOS 27 is expected to retain compatibility with all Apple silicon models. M1 Macs, in particular, are predicted to receive support for at least a few more years.

An official list of compatible devices from Apple will be published at WWDC, but for the moment, it is confirmed that at least these four Intel models will be excluded from macOS 27.

#### Related Developments

In a related update, there are rumors that iOS 27 will also cease support for four iPhone models this year, reflecting a broader trend in Apple’s move away from Intel architecture.

For users still using Intel Macs, the forthcoming lack of compatibility with macOS 27 may act as an incentive to consider updating their hardware.

Apple to Permit Alternative iOS App Stores in Brazil

Earlier this month, iHelpBR announced that iOS 26.5 RC has established support for app sideloading in Brazil, following a resolution with CADE, the country’s competition regulator, concerning the App Store’s policies. Brazilian users can now discover a new “App Installation” feature under Settings > Apps, which allows them to control their default applications, including choosing preferred apps for different functions.

At present, the App Installation option only shows the App Store. Apple’s description indicates that the default marketplace will be utilized for recommendations in Spotlight, Siri, Safari, and more. If additional marketplaces are incorporated, users can modify their default selection. Although the timeline for when Apple will initiate alternative app distribution in Brazil remains uncertain, the new setting suggests that implementation is on the horizon.

CADE’s stipulations explicitly require Apple to permit app distribution via alternative stores, and the newly introduced App Installation menu clarifies the consequences of selecting a marketplace other than the App Store. This implies a marketplace-oriented model rather than the Web Distribution option provided under the EU’s DMA reforms.

Apple’s alternative app store conditions in Brazil involve new fees. As per the agreement with CADE, Apple is entitled to levy a 25% App Store commission or 10% for developers in special programs, in addition to a further 5% fee for utilizing Apple’s in-app purchasing system. Apps distributed through the App Store can guide users to external payment methods without a charge for static text, but a 15% commission applies for active links or buttons. For applications from alternative app stores, Apple may enforce a 5% Core Technology Commission.

While Apple has yet to officially verify these terms, the support in iOS 26.5 suggests that the rollout is imminent.
