So I've done this (killall prefds as well as explicitly killing the cfprefsd root and user process). I'm working with an iOS app I've ported to mac via catalyst, and I cannot get rid of the messages.2020-01-07 16:56:48.238531-0800 NetProbe[68038:5897039] [User Defaults] Couldn't write values for keys ( ApplicationAccessibilityEnabled ) in CFPrefsPlistSource<0x600002c13b00> (Domain: com.apI get the message for each preference read or write. The app is sandboxed, but has read/write access for both user selected file and downloads folder. What do I need to do?

Apologies for the lack of formatting. I expected leading spaces would do it.

I'm getting this error relative to PlaygroundSupport: Module compiled with Swift 5.3.2 cannot be imported by the Swift 5.5 compiler I've brought the compiler in from Swift.org, and set it as the toolchain in Xcode. Any ideas how I can upgrade the module / what I've forgotten to do?

You'll want to make sure you're using a port that supports an external display. On the m1 iMacs, for example, there are 4 USB-C ports, but only two are marked for display, and the other two do not work for an external monitor.

Same error. Xcode Version 14.0 (14A309), Apple M1 iMac (24-inch, M1, 2021) with macOS 12.6 (21G115). Feedback FB11598250 filed, including code, screenshots, and diagnostics. Preview did work at one time, but now it's this: RemoteHumanReadableError: Failed to launch widget extension ================================== |  RemoteHumanReadableError |   |  NSError: Error Domain=CHSErrorDomain Code=1300 "(null)" ================================== |  MessageSendFailure: Message send failure for <ServiceMessage 151: relaunch>
