In the "mouseDown" (or MouseDreagged) code below Enclosure is a NSView subclass. xcode report 2 warnings: pb_item setDataProvider:self forTypes:[NSArray arrayWithObjects:NSPasteboardTypeTIFF, NSPasteboardTypePDF, @"LN_PboardType", nil]]; Sending 'Enclosure *' to parameter of incompatible type 'id _Nonnull' NSDraggingSession *draggingSession = [self beginDraggingSessionWithItems:[NSArray arrayWithObject:drag_item] event:drag_event source:self]; Sending 'Enclosure *' to parameter of incompatible type 'id _Nonnull' The application fail at: drag_item = [[NSDraggingItem alloc] initWithPasteboardWriter:pb_item]; Pasteboard item data provider <Enclosure: 0x7f849ec74e70> must conform to NSPasteboardItemDataProviderProtocol [General] There are 0 items on the pasteboard, but 1 drag images. There must be 1 draggingItem per pasteboardItem. However if in the line of code above "pb_item" is replaced by "drag_image" drag work fine (but without drop). The z_drag image follow the mouse correctly and "endedAtPoint" is called when the mouse button is released. Where is the error ? Any suggestion will be appreciate...

What is the Objective C equivalent of the command line diskutil unmount force ?

DADiskCopyDescription() give basic information for disk and partition but not how these info elements are linked together. By example how to get the volume parent container ? How to decode de CFSTR given by DADiskCopyDescription() ? When does DAMediaContent hold "GUID_partition_scheme" or "FDisk_partition_scheme" ? For volume DAMediaContent is something like "C12A7328-F81F-11D2-BA4B-00A0C93EC93B" (with volume name in DAMediaName). But DAMediaContent with such numeric value is not always volume (DAMediaName and DAVolumeKind are then empty). And sometime DAMediaContent is empty. Where can I found documentation about DADiskCopyDescription() and the way to get APFS volume\container childs and parent

How to compile arm .s, x86 .s (and .c, .m ) files to a single universal .app in Xcode project ?

If you trust the content of this file, open and save it to upgrade to the modern format. The "open and Upgrade" button make the MainMenu.xib not editable: it seem that every submenus has disappeared. How can I fix it ? Any suggestion will be greatly appreciate.
