In June 2017 Apple wrote

>At WWDC 2017, we announced new apps submitted to the Mac App Store must support 64-bit starting January 2018, and Mac app updates and existing apps must support 64-bit starting June 2018.

Open System Information (the Apple icon in the menu bar), and look in Software > Applications for the 64-bit column entry for your software. Check with the developer. When the June-ish update of macOS comes along it will natter you about 32-bit applications, and at a future time macOS will not open the application at all.

Is anyone still releasing 32 bit apps for the mac? The last time I shipped a 32 bit Apple application was around 2012.

Well, obviously there are people who do that. In my list of applications release in the past six months, and that are still flagged as not-64 bit, are all of the Adobe Creative Cloud account management tools (AAM), Synology utilities, Garage Band, CrossOver, the Kindle app, Mathematica, all the Concept Draw apps, and TheBrain 9. The last has attempted several times to issue updates that register as 64-bit and has failed every time, including yesterday.

I had a look on my laptop. There is quite a bitf stuff on there that is 32 bit as well, which is a surprise. Especially when it is big companies like Adobe and Microsoft.
