> Apple basically made everyone rewrite their apps instead of doing something sane - though admittedly they never had real support for multi-dpi, so perhaps that's an at least understandable solution. They did not make everyone rewrite their apps. The only apps that actually needed to change were the ones that were rendering text without using the Text rendering APIs of the OS (a small minority of apps). Everything else just worked totally fine. Yes, some icons might have been blurry, but functionality-wise everything was fine. This is in contrast to Windows where switching to HiDPI mode usually means cut-off texts, invisible buttons (pushed out of the dialogs they are in) and, as noted by the OP, sometimes a mish-mash of correct and incorrect rendering within the same window. You tell us you were shocked by how it was handled by Apple, so what would you have done differently? How would you have solved the issue in a way that requires even less work by app developers? Honest question. I really can't imagine a better solution than what Apple has done, but then again, the bulk of my knowledge is in databases, web servers, web applications and devops, so I'm sure I miss something that you can see. Hence I'm asking.
