App that runs fine under Xcode 15 does not work on Xcode 16.
When I upgraded to Sequoia 15.1, an app that worked fine under OS 14 stopped working. Out of 4 views on the main screen, only 1 is visible. Yet, if I click where another view should be, I get the expected action so the views are there, just not visible. Only I can't see where I am clicking! I had to upgrade to Xcode 16 to recompile the app and run it in Debug mode. When I do, I get the following: NSBundle file:///System/Library/PrivateFrameworks/MetalTools.framework/ principal class is nil because all fallbacks have failed. Can't find or decode disabled use cases. applicationSupportsSecureRestorableState FWIW - the only view that actually shows up is the last subview added to the main view.

NSScrollView of a large graphic jumps when scrolling on OSX Ventura (13.0.1)
This is an internal app that displays a large NSView (50K x 25K pixels) within a NSScrollView the size of my 27" iMac. The code worked fine, scrolling both ways was very smooth, under the latest release of OS-X 12. I upgraded to 13.0.1 and now the scrolling jerks every ~ 500 pixels in either direction. I am using XCode 14.1 and writing in Objective-C. I notice the NSLog now contains the message "Metal API Validation Enabled" which it never did before. Is this a bug or has something fundamental changed in Ventura which requires changing the viewing code. (Memo to self: NEVER install a ".0" release. Let somebody else be the guinea pig.) Thanks for whatever help you can provide. Ron

OSX NSFileManager Error 513
I am developing a new OS-X App. When I try to save a file using an internally-generated file name based on the most-recently read file, I get Error 513. Saving to a file whose name comes from NSSavePanel works fine. What privilege is the App missing? Error Domain=NSCocoaErrorDomain Code=513 "You don’t have permission to save the file “2022-09-03.xml” in the folder “2022”." UserInfo={NSFilePath=/Volumes/HDD2/Documents/OS-X Apps/Polls/2022/2022-09-03.xml, NSUnderlyingError=0x600002765740 {Error Domain=NSPOSIXErrorDomain Code=1 "Operation not permitted"}}
