Apple Reveals iOS 7 and the New Mac Pro

Apple’s WWDC 2013 keynote on June 10, 2013 featured two redesigns that signaled different directions: iOS 7 replaced the skeuomorphic visual language that had defined iPhone software since 2007, and the new Mac Pro abandoned the aluminum tower form factor that had served professional desktops since the Power Mac era. iOS 7 was led by Jony Ive following the departure of Scott Forstall in October 2012 — Forstall had championed the leather-and-wood textures, torn paper, and felt-covered stitching that Apple called skeuomorphic design. iOS 7 replaced all of it with flat, translucent surfaces, a system-wide blur effect (processing layers beneath the current view as frosted glass), a new thinner system font (Helvetica Neue Light), redesigned icons with a consistent rounded-rectangle grid, and physics-based animations using UIKit Dynamics. New features included Control Center (swipe up from any screen to reach brightness, Wi-Fi, Bluetooth, and media controls without leaving the current app), AirDrop for peer-to-peer file transfer over Wi-Fi Direct and Bluetooth LE, and iTunes Radio as a streaming music service competing with Pandora. iOS 7 shipped September 18, 2013 alongside the iPhone 5s and iPhone 5c, and within four days Apple reported 74 percent of active devices had updated — the fastest adoption rate for any iOS version to that point.

The new Mac Pro was the more radical engineering departure. The cylindrical design — quickly nicknamed the “trash can” — placed a triangular aluminium thermal core at the center, with components arrayed radially around it so a single axial fan drew air through all of them simultaneously. The CPU (Intel Xeon E5 with 4, 6, 8, or 12 cores) sat on one face of the triangle, with two AMD FirePro workstation GPUs (D300, D500, or D700 variants with 2–6 GB GDDR5 each) on the other two faces. Flash storage was built-in and not user-replaceable in the conventional sense. All external connectivity used Thunderbolt 2 at 20 Gbps (six ports), HDMI 1.4, four USB 3.0 ports, and dual gigabit Ethernet — meaning external chassis were required for users who needed additional PCIe expansion cards, additional drives, or professional video capture boards. The Mac Pro shipped December 19, 2013 starting at $2,999 for a 4-core configuration. The thermal design proved to be a long-term limitation: the dual-GPU assumption locked Apple into a particular GPU upgrade path that became untenable as workload patterns shifted toward single-GPU compute (Metal, Final Cut Pro X) rather than the dual-GPU OpenCL configuration the 2013 design optimized for.

The 2013 Mac Pro remained Apple’s professional desktop for over five years without an update — an unusually long gap that Apple publicly acknowledged in April 2017 when executives admitted the design had “painted us into a thermal corner.” The successor, announced at WWDC June 3, 2019 and shipping December 2019 as the Mac Pro, returned to a traditional tower form factor with full-length PCIe expansion slots, removable GPU cards, and expansion modules called MPX Modules — a direct reversal of nearly every design decision made in 2013. For developers in 2013, iOS 7 demanded more immediate attention than the Mac Pro: virtually every iOS app required visual updates for the new system appearance, as third-party apps designed around leather textures and glossy chrome buttons looked anachronistic against iOS 7’s flat aesthetic. Apple’s HIG (Human Interface Guidelines) were rewritten almost entirely, and Apple’s own apps — Calendar, Notes, Game Center, Newsstand — were redesigned to demonstrate the new visual principles developers were expected to follow.
