Apple has started warning about the end of support for some macOS applications

After the iPhones, Apple is going to end support for 32-bit applications in the case of the macOS operating system. The latest version of macOS 10.13.4 is the last in which 32-bit applications will be able to be used "without compromise". At the same time, the system notifies the user when he starts a 32-bit application. Thus, users will be able to get an idea of ​​which applications will stop working in the future (if the developers do not convert them to a 64-bit architecture).

A new warning appears to users when they run a 32-bit application for the first time on macOS 10.13.4 – “This app requires an update from the developers to improve compatibility". According to information from Apple, this version of macOS is the last in which you can use these old applications without much difficulty. Each subsequent version will introduce some additional compatibility issues, and the upcoming major update that Apple will present at WWDC will end support for 32-bit apps altogether.

The intention to end support for 32-bit applications is logical. Apple also explains this in a special document, which everyone can read. 64-bit applications can use significantly more system resources than their 32-bit predecessors.

It is likely that the vast majority of used and popular applications are already converted to 64-bit architecture. However, if you want to check your app list yourself, it's very easy. Just click on apple logo in the menu bar, select About this Mac, then the item System profile, bookmark Software and subpoint Application. Here is one of the parameters 64-bit architecture and all installed applications that do not support it will be marked here.

It's the same crap as removing support for 32-bit iOS apps. Dozens of useful applications stopped working on iOS and the developers did not upgrade them either due to lack of funds or it was simply not worth it... What would happen to Apple if they simply left the 32-bit support there? And the mentioned document - just marketing gimmicks, that 32-bit applications cannot address as much memory as 64-bit ones and do not use Metal - yes, that's true, but these applications don't even need it...
