Very few apps are still 32-bits. Most were updated years ago, if the developers had any sense. Macs have had 64-bit processors since the mid-2000s.
Now the push is on to create apps that run natively on Apple’s ARM-based Silicon, rather than requiring the Rosetta emulator. M1 native code provides a huge speed boost over Intel chips in many cases, at less cost.
