It's up to the OS to actually write the defaults to disk when it wants to. So if you write some prefs during the run of your screensaver, you have no idea *when* they'll actually be written to disk. And if your screensaver instances keep running because of the glaring bug that's in legacyScreenSaver, then the changed prefs might *never* be written. Looking at my code to handle the OK and Cancel actions for the config sheet, I still have these calls from way back: [defaults synchronize]; // It says this isn't needed, but it sure seems to be for a screensaver pref, with this comment: I'd say try using that and see if it helps. But, exactly why and when are you writing prefs during the run of your screensaver instances? Or are you only writing them during in the config sheet? Maybe we can figure out an alternate solution. > That whole business brings up the question: should we abandon > legacyScreenSaver? > > If I understand correctly, there is a new framework, something to do with > wallpapers? > I mean, the name "legacyScreenSaver" suggest, that this framework will be > going away anyways at some point ... > > What are your thoughts? The new screensaver/wallpaper model is for their silly idea of blending the 2 together. I see that if you run some of their older screensavers, they too wil continue to run for a while after you wake them. The Hello one will continue to use up to about 25% cpu afterward. So basically, Apple simply has a big problem with telling many screensavers to stop. They have not offered any Xcode template for a new style of screensaver. In face, the old one is still there, so Apple still expects new screensavers to use the legacy model. Let's hope they'll be smart and add one soon, but I'm not holding my breath. They appear to now live as an appex. I don't recall if that's how they distributed them in their previous life, before the wallpaper nonsense. /System/Library/ExtensionKit/Extensions/Hello.appex/Contents/MacOS/Hello -- Steve Mills Drummer, Mac geek _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
