In recent months, macOS High Sierra users, we have seen how the operating system reminded us over and over again that the application we were running (if it was not optimized for 64 bits) was not created to be compatible with 64-bit processors, so its performance could leave a lot to be desired. These messages were just a preview of one of the novelties of macOS Mojave.
The next version of Apple's operating system for Mac computers will be the last version released by Apple on the market that will allow running 32-bit applications. In this way, all the developers that today offer applications created only for 32 bits, will have to update them in the next year, if they want to continue being used.
32-bit applications, they do not take advantage of the full potential that 64-bit architecture offers us, architecture that allows applications to be faster and use as much memory as possible. Apple has begun to send emails to developers who today offer their applications in the Mac App Store urging them to update their applications, if they want to continue being an option to be taken into account by users with more updated Mac.
As with iOS 11, Apple will not remove from the Mac App Store all applications that are not updated, at least for now, since after the launch of macOS Mojave, many have been the computers that have been left out of this update, as we show you in this articlewhere can we see all the news that will come from the hand of the next version of the operating system for Mac.
Apps that are not updated will continue to appear in the Mac App Store, but we will not have the option to install them on our computer, as is the case with 32-bit applications available in the iOS App Store with devices running iOS 11 or higher.
