#61196: root6: uses macOS 10.10/10.12 APIs
--------------------------+--------------------------

     Type:  defect        |     Status:  assigned
 Priority:  Normal        |  Milestone:
Component:  ports         |    Version:  2.6.3
 Keywords:                |       Port:  root6
--------------------------+--------------------------
 Does the cocoa build of root6 intend to remain compatible with macOS 10.11
 and earlier, or has its minimum macOS requirement been raised? I notice
 that as of `root6 @6.22.00` it no longer builds on 10.11 and earlier due
 to usage of `NSWindowStyleMaskBorderless` (replacement for
 `NSBorderlessWindowMask`), and additionally it no longer builds on 10.9
 and earlier due to usage of the `CGContext` property of
 `NSGraphicsContext` (replacement for the `graphicsPort` property):

 Because these new APIs are replacements for existing ones, it might be
 possible to patch root6 and continue using it on older OS versions,
 assuming no other compatibility issues.

 There is also an error I don't know the reason for:
 {{{

 }}}
