I want to make an agent application in SwiftUI. It would be setup as a login item and have no dock icon and display no windows on start. I used AlertScene at first, but it is unavailable on macOS 14 which is my deployment target. Is there a way to have no windows or I'd better use AppKit for that?

I want to install Chrome extension via configuration profile without user needing to go to System Settings and install profile manually. Can i install configuraation profile by making user only interact with my app?

I'm trying to use ASWebAuthenticationSession on macOS but there is a weird crash and I have no idea what to do. It looks like there is a main thread check in a framework code that I have no control over. Any help would be appreciated. Thank you in advance.

We have a Privileged Helper tool that we install with SMJobBless. I would like to debug it. I've added WaitForDebugger in our helper tool launchd plist and it does wait. But I can't attach to it via Debug->Attach to Process in Xcode with error: Code: 3 Failure Reason: tried to attach to process as user 'myusername' and process is running as user 'root' I set Debug process as: root in scheme settings. But I'm not sure if it does anything since I'm not running this particular scheme at the moment of attach. I tried unsuccessfully to set "Wait for the executable to be launched" but I had to create a new scheme for it since helper is built as part of the main app so maybe I did something wrong. Am I doing something wrong or is it not possible to attach to root process?

I want to traverse my local Google Drive folder to calculate the size of all the files on my drive. I'm not interested in files or directories that are not present locally. I use getattrlistbulk for traversing and it takes way too much time. I think it is because FileProvider tries to download metadata for the directories that are not yet materialised. Is there a way to skip non-materialised directories?

It looks like macOS Sonoma doesn't delete /tmp files in containers periodically or on reboot, like it does for system /tmp or $TMPDIR. Is it a bug or is it in on purpose? Our app didn't delete its temp files and some users have quite a few of them. We will make the fix so that we clear after ourselves in the future but should we delete temp files manually on start for existing users?

I know that system /tmp and $TMPDIR are cleaned periodically and on reboot, but what about /tmp directory inside app containers? Because it looks like on macOS Sonoma it is not cleaned automatically and I was wondering if it is by design? And what should I do about it? Should I delete these files manually for existing users or is it possible to somehow nudge macOS into doing it?
