I wonder if developers have considered high-pixel-density support for tiles for
any device, whether it’s a Mac or not.
The openstreetmap-carto developers have been changing POI and other
icons from PNGs to SVGs for better high-resolution support, which would
include "retina" tiles. Unfortunately, released versions of Mapnik don't
support SVGs for background patterns, which would be a problem for some
features. I don't think any other developer work is required -
mod_tile/renderd already support scaling tiles
(https://github.com/openstreetmap/mod_tile/pull/82)
It would be up to the system administrators and OWG to decide if they
wanted to deploy retina tiles. Deploying a second set of tiles would
increase the CDN cache miss rate, increase the rendering required, and
significantly increase the disk space required for tiles. The last is
likely to be particularly significant as I don't believe the machines
have the free disk required to more than double the cache.
