I'm currently developing an application to that runs on MacOS versions 10.10 - 10.15. Since my development environment is Xcode10.1 on MacOS10.13, I am using the MacOSX10.10sdk. For the UI I am using StoryBoard. Using this set up I created my application and tested it on MacOS 10.10.5 and MacOS 10.11.6 using VirtualBox on MacOS10.13. When I tested it out on these two environments the installer window shows but there are no buttons, text, or labels showing. Cannot draw View Controller Storyboard 	- NSWindowController 		- NSWindow 			- NSThemeFrame 				- NSViewController 					- NSView 						- NSButton 						- NSTextField When I tested the application on MacOS 10.12 - 10.15 it ran correctly and the window displayed properly. What do you think might be the problem? If you have any ideas on how to solve this problem, it would be much appreciated. Best regards.
