Apple September Event 2025: macOS, MacBook, and Mac Device Leaks and Rumors Roundup

The Apple September Event 2025, scheduled for September 9, is fast approaching, and while the spotlight is on the iPhone 17 series, speculation about macOS and new Mac devices is heating up.

Although the event is primarily iPhone-focused, credible leaks and rumors suggest that macOS updates and potential Mac announcements could play a role. Drawing from trusted technology sources like Bloomberg, MacRumors, and AppleInsider, this article compiles the latest insights on macOS 26 Tahoe and possible MacBook and Mac reveals, offering a glimpse into what might be unveiled.

Highlights:

• Event Date and Time: September 9, 2025, at 10:00 a.m. PT, live-streamed on Apple’s website, YouTube, and Apple TV app.

• macOS 26 Tahoe: Expected to feature a Liquid Glass design, enhanced Apple Intelligence, and end Intel Mac support in 2026.

• MacBook Updates: M5-powered MacBook Pro models are rumored, but likely for an October 2025 or early 2026 launch.

• Other Macs: M5 Mac mini, iMac, and Mac Pro upgrades are in development, with releases expected later in 2025 or 2026.

• Wildcards: A budget MacBook with an A18 Pro chip or a new Mac Pro with M4 Ultra/M5 Ultra may debut later.

What’s New in macOS 26 Tahoe?

The upcoming macOS 26 Tahoe, previewed at WWDC 2025, is set to bring a major design refresh, dubbed Liquid Glass, inspired by iOS 26’s aesthetic.

This update promises a sleek, translucent interface with vibrant animations, marking the biggest visual overhaul since macOS Big Sur.

Posts on X highlight mixed sentiment, with some praising new features like group typing indicators, while others criticize UI inconsistencies. Apple Intelligence will expand with improved Siri functionality, though major upgrades are delayed until 2026.

Critically, macOS 26 will likely end support for Intel-based Macs in 2026, pushing users toward Apple Silicon. The public release is expected around September 15, alongside iOS 26.

Will We See M5 MacBook Pros at the Event?

Rumors suggest Apple is developing M5, M5 Pro, and M5 Max MacBook Pros in 14-inch and 16-inch sizes, but Bloomberg’s Mark Gurman indicates these are unlikely for September, with an October 2025 or early 2026 launch more probable.

The M5 chips, built on TSMC’s 3nm process, promise better performance and efficiency, with 2.5D packaging for improved cooling. No major design changes are expected, as Apple is saving OLED displays and thinner chassis for M6 MacBook Pros in late 2026.

Current M4 MacBook Pros, launched in October 2024, make a September refresh unlikely.

Could a Budget MacBook Be in the Works?A tantalizing rumor points to a low-cost MacBook, possibly codenamed J700, powered by an A18 Pro chip (used in iPhones) rather than an M-series chip.

This could revive the base MacBook line, offering an affordable option starting around $599-$799. Leaks from AppleInsider and iGeeksBlog suggest it’s aimed at students and budget-conscious users, potentially competing with Chromebooks.

However, this device is not expected at the September event and may debut in 2026, possibly alongside another mystery device (J804), which could be a low-end MacBook Pro or Mac Pro variant.

What About Other Mac Devices?

Apple is reportedly working on M5-powered Mac mini, iMac, and Mac Pro models. The Mac mini may see a significant redesign, shrinking to a size closer to an Apple TV box, with M5 and M5 Pro options.

The iMac could gain an M5 chip, with a 32-inch iMac Pro rumored for 2026. The Mac Pro, last updated in 2023 with an M2 Ultra, is overdue for an M4 Ultra or M5 Ultra upgrade, potentially supporting up to 512GB of Unified Memory.

These updates are more likely for an October event or later, as Apple typically reserves Mac launches for fall or spring.

Is a New Mac Studio or Studio Display Coming?

The Mac Studio, updated with M4 Max and M3 Ultra chips in March 2025, may receive an M4 Ultra or M5 upgrade in 2026. A new Studio Display with mini-LED backlighting and ProMotion is also rumored for late 2025 or early 2026, enhancing brightness and refresh rates.

These are unlikely for September, as Apple’s focus remains on iPhones and Apple Watches, but a surprise press release post-event isn’t out of the question, as seen with the M4 MacBook Air launch in March 2025.

What Software Features Will macOS 26 Bring?

Beyond its visual overhaul, macOS 26 Tahoe will integrate advanced Apple Intelligence features, including enhanced text generation and image creation via Image Playground.

The update will optimize performance for M-series chips, with a focus on AI-driven workflows.

Security patches and bug fixes, like those addressing Photos app issues, will accompany the release. However, some features, like live translation, may not be ready at launch, per tipsters. The beta is already available to developers, with public access expected soon after the event.

Could There Be Surprise Mac Announcements?

While the September event prioritizes iPhones, Apple Watches, and AirPods, Apple has a history of low-key Mac reveals via press releases. A new Mac Pro or Mac mini could be announced post-event, especially given the Mac Pro’s lack of updates since 2023.

Leaks about a foldable 17-to-20-inch MacBook with an M5 chip have surfaced, but this is slated for 2027 or later. The “Awe Dropping” theme and Liquid Glass logo don’t directly hint at Macs, suggesting iPhone 17 Air’s thin design is the focus.

The Apple September Event 2025 will likely center on iPhones, but macOS 26 Tahoe’s imminent release and whispers of M5 Macs keep the Mac community buzzing.

While major MacBook and Mac reveals are more likely for October or 2026, surprises could still emerge.

Tune in on September 9 at 10:00 a.m. PT to catch the latest, and stay tuned for potential Mac updates in the coming months.
