Johny Srouji is the Senior Vice President of Hardware Technologies at Apple Inc. who is responsible for the design of Apple's processors.

Srouji was born in Haifa, Israel to a family of Lebanese descent. He earned bachelor's and master's degrees in computer science from the Technion–Israel Institute of Technology in 1988 and 1990, respectively. He speaks Arabic, English, French, and Hebrew.

Srouji worked as a researcher and engineer at IBM R&D Labs in Israel from January 1990 to December 1992. He joined Intel at their Israel Design Center in January 1993 and where he became a senior manager. Srouji returned to IBM in January 2005 as a CPU design manager for their POWER7 series.

In March 2008, Srouji was recruited by Bob Mansfield to join Apple, where he led the development of the Apple A4, the first system-on-a-chip (SOC) to be designed at the company. The Apple A7 surprised the industry by moving Apple's mobile devices to 64-bit computing. After successfully rushing the Apple A9X to market for the iPad Pro in 2015, Srouji was promoted to Senior Vice President, leading development of Apple processors and reporting directly to CEO Tim Cook.

macOS High Sierra (version 10.13) was released on September 25, 2017. It was promoted as the last version of macOS to support 32-bit software "without compromise". It also introduced the new APFS file system to take advantage of faster solid state drives and address the looming 2040 date limit from the aging Mac OS Extended file format.

High Sierra was a free upgrade for owners of supported systems from Apple Inc. Though it introduced support for Metal 2, it does not require a Metal-compliant GPU as its successor macOS Mojave does.
