I am writing a login item and I am trying to find if its possible to get the current user. Lets say, I have logged in with user "Test" and when I execute the exe with root privileges and if I use char *user = getenv("USER"); user is "root". My expected answer is "Test". How can I get it? I don't know if I can put objective c code in login item? Is it possible to NSUserName in login item. NSString *user = NSUserName(); You want the SCDynamicStoreCopyConsoleUser function . QA1133 gives some relevant details and caveats. Login items can be Cocoa applications, so you can use NSUserName() (which is

I am getting an error –9405, couldntGetRequiredComponent , with SGNewChannel(m_Grabber, VideoMediaType, &m_Channel) on Mac system 10.9.1. This code works on older systems. Is anyone else having this issue? Edit - Initialization code: // standard SG initialization err = OpenADefaultComponent(SeqGrabComponentType, 0, &m_Grabber); err = SGInitialize(m_Grabber); err = SGSetDataRef(m_Grabber, 0, 0, seqGrabDontMakeMovie); After spending some time reverse engineering what SGNewChannel does on both OS X 10.8 and 10.9 I have found what might be the cause of the new behavior on 10.9. The SGNewChannel

I have a C++ codebase that has been around for a while (10+ years) and it compiles and runs fine, but I notice that when I compile it under OS/X 10.8.x (Mountain Lion), the compiler emits deprecation warnings about some of the Carbon functions it calls: ../system/SetupSystem.cpp:575:44: warning: 'UpTime' is deprecated: first deprecated in OS X 10.8 [-Wdeprecated-declarations] ../system/SetupSystem.cpp:575:22: warning: 'AbsoluteToNanoseconds' is deprecated: first deprecated in OS X 10.8 [-Wdeprecated-declarations] ../system/SystemInfo.cpp:249:25: warning: 'MPProcessors' is deprecated: first

I want to have clipped drawing on my CGContext but I need it just the other way round, i.e. I want to add several rectangles to my clipping path using CGContextAddRect() and the clipping should be done in the way that all the rectangles that I have added to my clipping path stay unaffected by any drawing operations. Normally, it's just the other way round, i.e. drawing functions draw to the rectangles that have been added to the clipping path and leave the areas that haven't been added to the clipping path unaffected. So I guess what I need is just a way to reverse the clipping path before

I'm not even sure where to begin with this question... I want to be able to send mouse-click events to another machine, as if the user had clicked on that machine. I can do it on the same machine via: CGEventSourceRef source = CGEventSourceCreate(NULL); CGEventType eventType = kCGEventLeftMouseDragged; CGPoint mouseCursorPosition; mouseCursorPosition.x = point.x; mouseCursorPosition.y = point.y; CGMouseButton mouseButton = kCGMouseButtonLeft; CGEventRef mouseEvent = CGEventCreateMouseEvent ( source, eventType, mouseCursorPosition, mouseButton ); CGEventSetType(mouseEvent,
