#57628: No Tiger restriction in DesktopManager
--------------------------+----------------------------
 Reporter:  chrstphrchvz  |      Owner:  (none)
     Type:  defect        |     Status:  new
 Priority:  Normal        |  Milestone:
Component:  ports         |    Version:  2.5.4
 Keywords:                |       Port:  DesktopManager
--------------------------+----------------------------
 `DesktopManager` (VirtueDesktops) only supported 10.4 Tiger, but the
 portfile does not enforce this using e.g. `${os.major} == 8`. There are
 errors when attempting to build on Leopard (see #13900) and later; on
 recent macOS versions, the error is due to an old project file format:
 {{{
 :info:build xcodebuild: error: Unable to read project
 'DesktopManager.xcode'.
 :info:build     Reason: Project file 'DesktopManager' was written by an
 unsupported Xcode version (39)
 }}}

 Note that VirtueDesktops was discontinued by its author several years ago,
 presumably since 10.5 Leopard and later versions include the Spaces
 feature (though some have attempted [https://shiftordie.de/blog/2007/11/26
 /virtuedesktops-and-leopard/ workarounds] for using VirtueDesktops on
 Leopard anyways).
