We recently heard that Apple will stop supporting 32-bit apps with the release of iOS 11, and now Apple has also confirmed that they will stop supporting 32-bit applications in macOS as well. This move marks a significant shift in Apple’s software ecosystem, pushing developers and users towards a more modern and efficient 64-bit architecture.
Apple has announced that from January 2018, all new applications submitted to the Mac App Store must be 64-bit. This requirement is part of Apple’s broader strategy to enhance performance, security, and compatibility across its devices. By transitioning to 64-bit apps, Apple aims to leverage the full potential of modern processors, which can handle more data at once and perform more complex computations compared to their 32-bit counterparts.
Transition Timeline for Developers
Developers will have until June 2018, so basically a year from now, to make their applications 64-bit and replace their 32-bit apps. This gives developers a clear timeline to update their existing applications and ensure they meet the new standards. The transition period is crucial as it allows developers to test their apps thoroughly and address any compatibility issues that may arise during the conversion process.
Apple announced their next major macOS release at WWDC 2017 on Monday, macOS High Sierra, and this will launch sometime this fall, probably in September or October. macOS High Sierra will introduce a range of new features and improvements, including enhanced graphics capabilities, a new file system, and updates to core apps like Safari and Photos. The shift to 64-bit apps is part of these broader enhancements, aimed at providing a smoother and more efficient user experience.
User Notifications and Impact
The company has also revealed that it will start warning users about 32-bit apps with the release of macOS High Sierra. This is something that it does at the moment with iOS apps. When users open a 32-bit app on macOS High Sierra, they will receive a notification informing them that the app is not optimized for the latest macOS version and that it may affect system performance. This proactive approach ensures that users are aware of the impending changes and can seek out 64-bit alternatives or updates from developers.
Apple’s iOS 11 is also expected to land in September with the new iPhone 8 and iPhone 8 Plus. Once this is released, 32-bit applications will no longer be supported on iOS. This means that any 32-bit apps currently installed on users’ devices will cease to function, prompting users to update to 64-bit versions if available. The removal of 32-bit support on iOS is part of Apple’s ongoing efforts to streamline its app ecosystem and improve overall device performance and security.
The transition to 64-bit apps is not just a technical upgrade; it represents a broader commitment to innovation and efficiency. 64-bit architecture allows for better memory management, faster processing speeds, and enhanced security features. For example, 64-bit processors can handle larger amounts of RAM, which is essential for running complex applications and multitasking. Additionally, 64-bit apps can take advantage of advanced security features like Address Space Layout Randomization (ASLR), which makes it more difficult for malicious software to exploit vulnerabilities.
In conclusion, Apple’s decision to phase out 32-bit apps in favor of 64-bit architecture is a significant step towards modernizing its software ecosystem. By setting clear timelines and providing user notifications, Apple is ensuring a smooth transition for both developers and users. This move will ultimately lead to better performance, enhanced security, and a more seamless user experience across all Apple devices.
