Re: Proper way to retrieve the NSScreenNumber in a screen saver ?
I mentioned somewhere in one of my replies that you know when it’s being run in
the System Prefs preview because isPreview is passed to the main entry point.

Re: Proper way to retrieve the NSScreenNumber in a screen saver ?
Thanks again for the responses. And sorry for following up so much later.
(a bit of context is recapped below)
First of all, thanks for the hint to viewDidMoveToWindow.
So, currently , I do this in my viewDidMoveToWindow:
- (void) viewDidMoveToWindow
{
window_ = [self window];
NSUInteger idx_of_screen = [NSScreen.screens indexOfObject: window_.screen];
displayID_ = [NSNumber numberWithUnsignedLong: idx_of_screen ];
On my Mac this runs fine, and I get a proper idx_of_screen/displayID_;
However, one of my users sent me a log file, which shows that on his Mac, [self
window] is non-null, but indexOfObject: returns NSNotFound, in the case where
my screensaver is running in the preview of System Preferences.
(One difference between the systems is that I am still using macOS 12, while he
is using macOS 13.)
I guess, there is not much I can do about it, except find some kind of
work-around for those cases, where this happens. Right?
Best regards, Gabriel

Re: How to convert path through container into standard form?
Have you tried -URLByResolvingSymlinksInPath? As far as I’m aware, the Pictures entry inside your container is a symlink to the real thing, so assuming you have appropriate entitlements, should be possible to resolve it.

How to convert path through container into standard form?
I have an NSURL * pictures_path; By default, this is set to pictures_path = [ [NSFileManager defaultManager] URLForDirectory: NSPicturesDirectory inDomain: NSUserDomainMask appropriateForURL: nil create: NO error: ]; This works fine. Occasionally, I am printing a log message, like so: mesg = [[NSMutableString alloc] initWithString: [mainDirectoryLocation_ pictures_path] ]; and then output that to whatever channel is active (screen or log file). Now, in cases where pictures_path is still set to the default, the users sees some thing like: /Users//Library/Containers/com.apple.ScreenSaver.Engine.legacyScreenSaver/Data/Pictures which is confusing to the user (and takes up a lot of space). How can I convert this back to the more human-readable /Users/xx/Pictures or ~/Pictures ? I have checked NSURL's doc, but couldn't find a method to convert the path. Hints will be appreciated.
