I've encountered a very strange issue that affects my code running only on OSX 10.10 systems. I've seen this anomaly occur on over 25 OSX 10.10 systems running my code, whereas the exact same code did not exhibit this behavior before upgrading (10.7). Furthermore, this issue is not 100% reproducible in that it occurs randomly ~0-5% of the time. While testing the code, nothing else critical or CPU exhaustive is occurring on the machine. Even if something else was happening, the very fact that the delays I'm experiencing are soooo ridiculously long make that conclusion seem suspicious. Anyhow,

We have developed an Authorization Plug-in that uses an SFAuthorizationPluginView to present UI to the user. This example is based on the "old" NameAndPassword example provided by Apple. We are using this Authorization Plug-in to unlock the session (we have updated the "system.login.screensaver" authorization in the authorizationdb) using a custom view. This worked well until the last update to Yosemite. Since Yosemite, the SFAuthorizationPluginView is not closing anymore after the user logged into the session. We could update the example to force closing the window, by doing something like: /

I have recently updated my OS X to 10.10 and since then facing issue installing ruby through RVM. There is a dependency on gcc46 which I am unable to resolve. Any help is appreciated. Below is the error stack. rvm reinstall ruby-1.9.3-p547 ruby-1.9.3-p547 - #removing src/ruby-1.9.3-p547 - please wait ruby-1.9.3-p547 - #removing rubies/ruby-1.9.3-p547 - please wait Searching for binary rubies, this might take some time. No binary rubies available for: osx/10.10/x86_64/ruby-1.9.3-p547. Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies. Checking

Since the last OSX update (Yosemite), my localhost server is full of error messages from airplay (but I am not using it). Each times it's the same: [31/Oct/2014 05:40:42] code 400, message Bad request version ('RTSP/1.0') [31/Oct/2014 05:40:42] "GET /info?txtAirPlay&txtRAOP RTSP/1.0" 400 - It's just annoying to have its server full of error messages so if anyone has a clue to fix that or to remove airplay, I would be very thankful :) I think I found the answer: On a cisco discovery forum they listed an nmap output that revealed the Yosemite discoveryd port ranges. Turns out the Apple is using

I have a litle problem with saving a color in NSUserDefaults . In objective-c is easy : -(NSColor *)colorForKey:(NSString *)key{ NSData *data; NSColor *color; data = [[NSUserDefaults standardUserDefaults] objectForKey:key]; color= [NSUnarchiver unarchiveObjectWithData:data]; if( ! [color isKindOfClass:[NSColor class]] ){ color = nil; } return color; } -(void)setColor:(NSColor *)color forKey:(NSString *)key{ NSData *data = [NSArchiver archivedDataWithRootObject:color]; [[NSUserDefaults standardUserDefaults] setObject:data forKey:key]; } The above code works fine in objective-c, but when i try
