Apple shipped the world’s first 64-bit personal computer over 14 years ago with the release of the Power Mac G5 on June 23, 2003. Apple unveiled the world’s first 64-bit smartphone (iPhone 5s) on September 10, 2013.
At WWDC 2017, we announced new apps submitted to the Mac App Store must support 64-bit starting January 2018, and Mac app updates and existing apps must support 64-bit starting June 2018. If you distribute your apps outside the Mac App Store, we highly recommend distributing 64-bit binaries to make sure your users can continue to run your apps on future versions of macOS. macOS High Sierra will be the last macOS release to support 32-bit apps without compromise.
