Apple Leaks Digest — June 5, 2026: MacBook Ultra moves to September, macOS 27 cuts Intel, and Gurman has more on the way
Omdia's display supply-chain data puts the MacBook Ultra at September; macOS 27 drops Intel Macs but keeps Rosetta 2 one more year; iOS 27 will reportedly cut iPhone 11 from the supported list; and the iPhone 18 Pro Max thickness may not change after all. Plus: Gurman's full WWDC preview lands today.
Three days before WWDC, the final wave of pre-keynote leaks is filling in the gaps. A new display supply-chain report pulls the MacBook Ultra's launch window forward to September. MacRumors compiled everything known about macOS 27, and the picture is clearer than expected: Intel Macs are officially out, Rosetta 2 gets one last reprieve, and the Mac is getting hidden prep work for a touchscreen future. A Weibo leaker says iOS 27 drops the iPhone 11. And the iPhone 18 Pro Max's thickness may not change at all — a reversal from the same source who claimed otherwise in March. Oh, and Gurman says he has a full WWDC/Siri preview coming today.
MacBook Ultra: September launch now the base case
The MacBook Ultra — Apple's rumored OLED-display overhaul of the MacBook Pro lineup — moved closer to a firm release date. Display research firm Omdia reports that Samsung will begin shipping OLED panels to Apple from July, covering two sizes: 14.3 inches and 16.3 inches (slightly larger than the current 14.2" and 16.2" MacBook Pro screens).1
The panel technology is notable: a hybrid combining oxide TFT backplanes with RGB tandem OLED — a first for this product category. Omdia says the combination is more power-efficient than either LTPO or standard single-stack RGB OLED alone, which would let Apple maintain MacBook Pro-level battery life in a thinner chassis.
Based on the July panel shipment start, Omdia places the MacBook Ultra in Q3 2026 — which almost certainly means the September iPhone event rather than a standalone announcement. Earlier expectations had pointed to October–November at the earliest, with some projections pushing into early 2027. If Omdia is right, the MacBook Ultra arrives alongside the iPhone 18 Pro and iPhone Ultra.

This corroborates the prior Kuo report that the Samsung OLED production line hit a mass production milestone — though Kuo's take through May was that early 2027 remained a risk due to the memory shortage. The Omdia read is more optimistic.
macOS 27: Intel is out, Rosetta 2 stays for one more year
The clearest macOS 27 summary to date came together through MacRumors' compilation ahead of WWDC.2
The headline: macOS 27 will drop support for Intel Macs entirely. macOS 26 (Tahoe) is the last release to support Intel hardware. Rosetta 2, however, survives into macOS 27 — meaning Intel-compiled apps still run on Apple Silicon. It won't be removed until macOS 28.
The known feature list:
- Liquid Glass tweak — The divisive translucency effect introduced in macOS 26 is staying, but Apple is working on a "slight redesign" to adjust transparency and shadow rendering. Not a rollback; a refinement.
- Smarter Siri — A standalone Mac Siri app is expected alongside the iOS version, with the same dark UI and ChatGPT-style chat history.
- Photos editing — "Extend" (generate beyond image edges) and "Reframe" (adjust perspective post-capture) are coming to the Mac. The natural-language photo editing tool may not ship at launch.
- Image Playground — Testing more realistic image generation models; likely a UI refresh.
- AI Wallpaper generator — Image Playground-powered wallpaper creation baked in.
- Shortcuts natural-language builder — Ask Siri in plain English to build a Shortcut; the system writes the workflow.
- Grammar checker — Writing Tools gets a grammar check layer on top of its existing spelling tools.
- Safari auto-tab grouping — Browser tabs get AI-sorted into groups automatically.
- Hidden touchscreen prep — macOS 27 code reportedly contains early optimizations for touch input, ahead of the OLED MacBook Pro / Ultra arriving with a touchscreen display. Apple hasn't announced this publicly; it's code-level evidence.
The overall character: Gurman has described it as a "Snow Leopard-style" release — less about showy new features, more about fixing what's underneath. Battery life improvements are explicitly part of that.
iOS 27 compatibility: iPhone 11 and SE 2 are out
Instant Digital, a Weibo leaker with a mixed but credible track record on Apple software predictions, says iOS 27 will require at minimum an iPhone 12.3 The devices getting cut:
- iPhone 11, 11 Pro, 11 Pro Max
- iPhone SE (2nd generation)
That's Apple's standard seven-year support window — all four models launched in 2019–2020. They'll continue receiving iOS 26 security patches for years.
The revamped, ChatGPT-style Siri will require an iPhone 15 Pro or newer — the Apple Intelligence hardware tier. Every other iPhone 12–14 gets iOS 27, just not the personal-context Siri.
Credibility note: Instant Digital has called Apple colors and hardware details accurately before (the iPhone 14 yellow color, Apple Watch Ultra 2 Titanium Milanese Loop). Software compatibility lists are harder to verify pre-WWDC. Take this as likely but not confirmed.

iPhone 18 Pro Max: thickness reversal
Ice Universe reversed his earlier hardware call. In March, he said the iPhone 18 Pro Max would be slightly thicker than the 17 Pro Max at 8.8mm. This week, he updated that to: same thickness as the 17 Pro Max, 8.75mm.4
His explanation: the Pro lineup isn't getting major structural changes because Apple's engineering focus this year is the iPhone Ultra foldable. Battery capacity could still rise — Digital Chat Station previously reported a 5,100–5,200 mAh cell, up from the 17 Pro Max's 5,088 mAh — without a thickness change if Apple has miniaturized other components inside.
This contradicts the prior claim from Instant Digital that the 18 Pro Max would be the heaviest iPhone ever, over 240 grams. Both signals remain unresolved. The picture right now: dimensions likely stable, weight and battery configuration still uncertain.
What's coming today: Gurman's full WWDC preview
Just after midnight UTC on June 5, Gurman posted that his "WWDC, iOS 27 and Siri preview" is dropping Friday — that's today.5 He also spent a few minutes musing publicly about macOS naming, noting that Apple is "reaching the point where we're running out of good names." Big Bear and Mammoth are the best of the remaining California landmarks, he said — which tracks with the "Big Bear" hashmoji leak from this week.6

His WWDC preview will almost certainly contain the definitive pre-keynote read on what iOS 27 and the new Siri will actually look like when Apple takes the stage Monday morning. Worth watching for later today.
