Exactly the same problem .. an overnight install ended up on my production APFS volume. I assumed that the installer, not having any input from me, defaulted to do that. However, I repeated the process watching it all the way and it happened again without any request for volume choice. This is a serious time waster .. I suppose I'm going to have to create an installer on an external disk which I can do but why are we having this issue and the other million developers are not?

When using MKMapView within SwiftUI in MacOS, via NSViewRepresentable and a Coordinator, the are several console messages per second "CVDisplayLinkSetPaused", alternating between [TRUE]and [FALSE] when displaying a poly line and/or annotations. .. also seeing my log deluged with this effect, but in my case, none of the above conditions are true. There is significant use of SceneKit but no SwiftUI, MapView, or anything else from the quote above (unless "poly line" is equivalent to SceneKit drawing a twisty line through a 3-D space). MacBook Pro (16-inch, M1 Max, 2021); macOS 12.3.1 (21E258); Xcode 13.3.1 (13E500a)

None of the suggestions made here have resolved the problem for me (nor for some others, as noted above). You don't even have to build anything to get this to happen: % xcodebuild --help 2022-04-22 19:10:49.692 xcodebuild[53065:8448383] Requested but did not find extension point with identifier Xcode.IDEKit.ExtensionSentinelHostApplications for extension Xcode.DebuggerFoundation.AppExtensionHosts.watchOS of plug-in com.apple.dt.IDEWatchSupportCore 2022-04-22 19:10:49.692 xcodebuild[53065:8448383] Requested but did not find extension point with identifier Xcode.IDEKit.ExtensionPointIdentifierToBundleIdentifier for extension Xcode.DebuggerFoundation.AppExtensionToBundleIdentifierMap.watchOS of plug-in com.apple.dt.IDEWatchSupportCore Usage: xcodebuild [-project <projectname>] [[-target <targetname>]...|-alltargets] . . . .

.. but not the actual content of the image, the only criterion I care about ?!
