Comment:

 "appleframeworks" appears to be gtk3's generic name for any Apple
 framework. According to
 [https://gitlab.gnome.org/GNOME/gtk/-/blob/3.24.38/gdk/quartz/meson.build?ref_type=tags#L48-53
 the source code], it is looking for the frameworks CoreGraphics, AppKit,
 Cocoa, Carbon, QuartzCore, and IOSurface, and all of them are marked
 required.

 Although [https://developer.apple.com/documentation/coregraphics
 CoreGraphics] was available in earlier Mac OS X versions as part of the
 ApplicationServices framework, it was not a top-level framework until OS X
 10.8, and meson can only find top-level frameworks, therefore we use
 [browser:macports-ports/gnome/gtk3/files/patch-quartz-meson-
 appleframeworks.diff?rev=fb2e768a990260b7f04b447ead2596c96f3bbd97 a
 patchfile] that makes CoreGraphics optional. That's the first "NO (tried
 framework)" in your output and is fine.

 AppKit, Cocoa, Carbon, and QuartzCore were all found, so that's fine.

 [https://developer.apple.com/documentation/iosurface IOSurface] was
 introduced in Mac OS X 10.6, which is the second "NO (tried framework)" in
 your output. Since IOSurface is still marked as required, this is why your
 build fails on Mac OS X 10.5. I don't know how gtk3 uses IOSurface so I
 don't know whether it can be made optional.
