On this week's episode of The MacRumors Show, we talk through everything the iPhone 18 Pro will feature, according to the latest rumors.

Following last year's major redesign, the ‌iPhone 18 Pro‌ models are expected to feature a very similar design to their predecessors. There is expected to be a smaller Dynamic Island, with Face ID's flood illuminator component moved under the screen to reduce the cutout's size. It is rumored to be approximately 35% narrower than the iPhone 17 Pro's, shrinking from around 20.7mm to 13.5mm. The Pro Max will be slightly thicker than its predecessor, rising to around 8.8mm and over 240 grams to accommodate a larger battery of 5,100 to 5,200 mAh, up from the ‌iPhone 17 Pro‌ Max's 5,088 mAh.

The rear will see a slight design shift as well. Apple is reportedly dropping the two-tone look found on ‌iPhone 17 Pro‌ models in favor of a more seamless aesthetic, with improved alignment between the Ceramic Shield back glass and the aluminum frame. The devices are also expected to come in a special red color.

The camera system will undergo more substantial changes. Both Pro models' main 48-megapixel Fusion camera are rumored to feature variable aperture, which would allow users to control the lens opening to manage light intake and depth of field. The aperture would function similarly to a DSLR camera, giving photographers greater control over focus sharpness and background blur in different lighting conditions. Additionally, Samsung is developing a new three-layer sensor for the ‌iPhone 18 Pro‌, designed to reduce noise, improve dynamic range, and enhance camera responsiveness compared to Sony's current sensors.

The Camera Control button is also getting a simplification. Rather than supporting both capacitive touch gestures and pressure sensing as on the iPhone 17, the iPhone 18 will rely on pressure sensing alone, reducing manufacturing complexity and the cost of repairs, while improving ease of use.

The A20 Pro chip will mark Apple's debut of a 2-nanometer processor, with a reportedly 15% speed increase and about 30% better power efficiency compared to the A19 Pro. The chip will use TSMC's Wafer-Level Multi-Chip Moduletechnology, integrating RAM directly onto the same wafer as the CPU, GPU, and Neural Engine rather than mounting it separately, which should improve performance and battery life while reducing the physical footprint of the chip.

The ‌iPhone 18 Pro‌ models will also feature Apple's C2 modem, which is expected to bring faster speeds, improved power efficiency, and support for mmWave 5G in the United States, a capability absent from the C1 and C1X modems used in earlier iPhones. Other upgrades include Apple's N2 wireless chip and 5G satellite internet.

The ‌iPhone 18 Pro‌ and ‌iPhone 18 Pro‌ Max are expected to launch in September 2026, with the standard ‌iPhone 18‌ and the lower-end iPhone 18e following in spring 2027. A foldable iPhone is also expected to debut alongside the Pro models in the fall.

On this week's episode of The MacRumors Show, we discuss Apple's announcement of its 37th annual Worldwide Developers Conference (WWWDC), where the company is expected to unveil a major Siri overhaul alongside iOS 27, macOS 27, and other next-generation operating systems.

Like last year, WWDC 2026 will be a primarily online event open to all developers at no cost, with an in-person component at Apple Park in Cupertino reserved for developers and students selected through a random lottery. Apple will notify accepted in-person attendees on April 2. The keynote and all sessions will be available on the Apple Developer app, Apple's website, and YouTube, with over 100 video sessions and interactive labs with Apple engineers and designers planned across the week.

Apple first unveiled Apple Intelligence at WWDC 2024, promising a smarter Siri with personal context, on-screen awareness, and deeper app integration, features that were delayed in March 2025, delayed again at WWDC 2025, and then missed a further internal target of iOS 26.4. Apple confirmed in its announcement that the conference will "spotlight incredible updates for Apple platforms, including AI advancements and exciting new software and developer tools," which points clearly to what is shaping up to be the most consequential ‌Siri‌ update ever.

The revamped ‌Siri‌ is said to be a sweeping redesign that turns Apple's long-struggling assistant into a full AI chatbot, with Bloomberg's Mark Gurman reporting that Apple is testing a standalone ‌Siri‌ app displaying prior conversations in a list or grid, with pinned and searchable chats and iMessage-style chat bubbles. ‌Siri‌ is also said to be gaining Dynamic Island integration, with a glowing icon and "searching" label while processing requests, an "Ask ‌Siri‌" button in third-party app menus, and a "Write with ‌Siri‌" keyboard option, while Spotlight is expected to be replaced by ‌Siri‌ as the primary search interface on iPhone.

The technology underpinning virtually all of this comes from Apple's multi-year partnership with Google, under which next-generation Apple Foundation Models are based on Gemini, with processing continuing to run on-device and in Private Cloud Compute. Separately, Apple plans to open Siri to third-party AI chatbots in ‌iOS 27‌ via an "Extensions" system in Settings, ending OpenAI's exclusive arrangement and allowing users to direct queries to Claude, Gemini, Grok, and others.

Beyond ‌Siri‌, iOS 27 is expected to be a relatively lean update, described as a "Snow Leopard" year, focused on performance improvements, bug fixes, and code cleanup rather than major new feature additions. Notable exceptions include optimizations for Apple's first foldable iPhone, which is expected to launch in the fall, and new satellite connectivity features.

macOS 27 will apparently share the same ‌Siri‌ upgrades and "Snow Leopard" stability focus. It will drop support for Intel-based Macs entirely. Apple will also unveil iPadOS 27, watchOS 27, tvOS 27, and visionOS 27 at the keynote.
