Apple began transitioning to 64-bit hardware and software technology for Mac over a decade ago, and all modern Macs now include powerful 64-bit processors that can run advanced 64-bit apps. These apps can access dramatically more memory, enable faster system performance, and take advantage of technologies that define today's Mac experience, such as Metal graphics acceleration.
Apr 04, 2017 iOS 11 drops support for legacy 32-bit apps. In this tutorial, we’re going to lay out how you can quickly identify any 32-bit apps that are installed on your iPhone, iPad or iPod touch. If you have 32-bit apps on your device, they won’t launch after updating to iOS 11.
