Mac OS X

When users attempt to launch a 32-bit app in 10.13.4, it will still launch, but it will do so with a warning message notifying the user that the app will eventually not be compatible with the operating system unless it is updated. This follows the same approach that Apple took with iOS, which completed its sunset of 32-bit app support with iOS 11 last fall.

This is good. I would prefer other companies, too, take a more aggressive approach towards deprecating outdated technology in consumer technology.

Thom, why do you think 32-bit technology is outdated?

I understand we need databases to have access to more than 4gb (2^32) of RAM, animation rendering software, graphical software, etc. that needs to have huge amounts of RAM.

But our Angry Birds, a Sudoku game, our calendars, YouTube, all social media apps, etc. DO NOT need to address 4gb or RAM and in such cases, they are good staying as 32-bit apps.

64-bit apps can access more RAM and have more CPU registers available, BUT, the memory footprint of most applications is larger too because of pointers size being used intensively.

So, getting rid of 32-bit support is, IMO, only a way of saving money having less architectures to maintain.

Java 7+ has a nice workaround to have shorter pointers in 64-bit tech:
