Error opening subprocess with fork() and AVCaptureSession
Hi! I am making an app that records the screen and microphone in MacOS, I specifically need it to run in a subprocess, for this I use fork(); The truth is that it marks the following error in loop: Error: CMIOHardware.cpp:379:CMIOObjectGetPropertyData Error: 2003332927, failed 2022-03-01 20:19:41.708913+0100 WebCamProj[8051:91700] [] CMIO_Unit_Convertor_VideoToolboxCompressor.cpp:461:rebuildVideoCompressor ### Err -12903 2022-03-01 20:19:41.709213+0100 WebCamProj[8051:91700] [] CMIO_Unit_Convertor_VideoToolboxCompressor.cpp:1958:doCompressBuffer [0x15382da00] EXCEPTION ON ERROR -12903 The example on which I base is the following, it comes from Apple's official website for developers: https://developer.apple.com/library/archive/qa/qa1740/_index.html The fragment that executes the operation looks something like this: pid_t pidScreenRecorder; if ((pidScreenRecorder = fork()) == 0) { NSURL *pathUrl = [[NSURL alloc] initFileURLWithPath:[NSString stringWithFormat:@"%@%s", NSHomeDirectory(), "/myScreen.mov"]]; ScreenRecord *screenRec = [[ScreenRecord alloc] init]; [screenRec startScreenRecording:pathUrl];   } I do not know why this error occurs only with this API, I have used others, for example AVAudioRecorder individually and I have not had any problem. Thanks you.

How to remove executable applications from TCC .
I have created a command line application with Xcode, the application acquires permissions to capture screen (for example) however then I would like to remove only it with the command tccutil reset All [bundler id] the problem is that my executable seems to have no bundler id and I don't know how to remove it. I have also modified the Product Bundle Identifier option in the Build Settings tab but this didn't work either.

Question about IOHIDRequestAccess
Hi, I use a program that needs Input monitoring to work, I am using the following to check: bool checkPermission = IOHIDRequestAccess(kIOHIDRequestTypeListenEvent); This works in principle but does not work in real time; for example, if I uncheck my application's box in Input Monitoring in Security and Privacy the method keeps throwing me 1 as if I had permission, unless I restart the application instance, then it will show 0. Is there any way to get in real time app permissions? Thanks you.
