macOS High Sierra 10.13.4 beta 1 was released last night by Apple, the new version of the operating system bringing an important change to the Mac. More precisely, the Apple company announces to users who install macOS High Sierra 10.13.4 beta 1 when using applications created using the 32-bit, outdated architecture.
macOS High Sierra 10.13.4 beta 1 promotes the use of 64-bit, modern applications that work much better in the macOS operating system, and they will be mandatory in the future. For now, Apple is just telling users that those 32-bit applications should be replaced with 64-bit ones, something that will definitely be imposed, maybe as early as 2018.
Apple has not yet announced when it will drop support for 32-bit applications in macOS, but the alerts will make many users think the moment they see them. Apple abandoned support for 32-bit applications in iOS for some time, so it was normal to see a major change prepared for the macOS platform as well.
macOS High Sierra 10.13.4 beta 1 displays these alerts in Macs after Apple announced as early as WWDC 2017, in June, that it would remove support for 32-bit applications. Of course, developers still have time to prepare their applications for the 64-bit update, so it remains to be seen exactly what they will do with them in the future.
