Start64!Apple published a new blog post on Friday on its developer website reminding all devs that it will no longer accept 32-bit apps in the Mac App Store starting January 1, 2018.

During the WWDC 2017 conference in June, Apple warned developers that 32-bit apps would go extinct for both iOS 11 and macOS High Sierra operating system, though the latter is still supporting them.

The company now informs application developers that they will no longer be able to submit 32-bit apps to the Mac Store Store starting next month, January 1, 2018, as well as that they need to update their existing apps to 64-bit until June 2018.
