To be clear there’s only been a single generation (2006) of x86 based Macs that weren’t 64bit. They’ve been telling everyone since 2007 (well actually earlier even, the final PPC generation was 64bit), that the 32bit was going to go away.

I hate to defend Apple arbitrarily but all us developers had plenty of notice, and had to specifically reconfigure the default settings on their projects to only be 32bit. If developers ignore deprecation notices for over a decade, then is it really the fault of the other side?

At least people can know which jobs not to take immediately.

Preview on macOS can do it. While it obviously doesn’t help everyone I’m not sure some Mac users realize there’s a built in tool for it
