• DIYer Upgrades MacBook Neo to 1TB: The base model MacBook Neo is officially capped at 512GB, but YouTuber dosdude1 proved it can be upgraded by soldering a 1TB NAND NVMe SSD module commonly used in the iPhone 16 Pro. Because the Neo shares the A18 Pro chip with the iPhone, the $210 component worked flawlessly, creating one of the only 1TB Neos in existence. (Macworld)
• Apple Expands Self Service Repair for 7 New Devices: Apple now sells genuine parts and tools for devices like the MacBook Neo, iPhone 17e, and the M5 Mac lineup. Most notably, the repair manuals reveal that the MacBook Neo’s keyboard can be replaced individually for $140, bypassing the expensive and complex $400-$600 “Top Case” replacements required on the MacBook Air and Pro.

• Apple Subpoenas Samsung in DOJ Antitrust Case: Apple is utilizing international legal mechanisms to demand internal market research and switching data from Samsung’s South Korean parent company. Apple hopes to use Samsung’s data on software like Smart Switch to defend itself against the Department of Justice’s allegations that the iPhone ecosystem stifles competition. (MacRumors)
• FBI Recovers Deleted Signal Messages via Notifications: A new report highlights that the FBI extracted deleted Signal messages from a defendant’s iPhone by accessing Apple’s internal notification storage. Because the user hadn’t disabled message previews in their notifications, the incoming message content remained cached in the device’s database even after the Signal app was completely uninstalled.

Researchers detail how a prompt injection attack bypassed Apple Intelligence protections (9to5Mac) Security researchers successfully combined two exploit methods to trick Apple’s on-device AI model into executing attacker-controlled actions. By writing harmful text backwards and using a Unicode right-to-left override, they bypassed input and output safety filters while utilizing a second technique to override the model’s instructions. Apple was notified of this vulnerability in October 2025 and has since deployed mitigations in the iOS 26.4 and macOS 26.4 updates.

Apple Card’s transition to Chase: Here’s what’s not changing (and might be) (9to5Mac) As Goldman Sachs exits its partnership with Apple, a new support page details what consumers can expect when Chase officially takes over the Apple Card. The core benefits—including zero fees, up to 3% Daily Cash, and the Mastercard network—will remain entirely unchanged. However, Apple’s wording leaves some ambiguity over whether elements like card numbers, physical card designs, and zero-interest Apple Card Monthly Installments (ACMI) might shift down the line.

Mac OS X Cheetah Successfully Ported to Nintendo Wii (MacRumors) A developer successfully managed to run Apple’s Mac OS X 10.0 Cheetah on a Nintendo Wii, taking advantage of the console’s PowerPC 750CL processor, which is structurally similar to the chips Apple used in the G3 iBook and iMac. The impressive hack required compiling a modified kernel, writing custom drivers to boot from the Wii’s SD card slot, and bridging the OS interface to work with the console’s video hardware. The developer even managed to get USB mouse and keyboard peripherals working on the ported OS.
