what is this appleframework? I am not good at meson output.. but apparently it prints out what it finds but not what it misses?

"appleframeworks" appears to be gtk3's generic name for any Apple framework. According to ​the source code, it is looking for the frameworks CoreGraphics, AppKit, Cocoa, Carbon, QuartzCore, and IOSurface, and all of them are marked required.

Although ​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 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.

​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.

Replying to ryandesign:

I don't know how gtk3 uses IOSurface so I don't know whether it can be made optional.

It looks like ​this merge request is where the IOSurface work went in. You can read about what it's used for there.
