Hi there! Please advice how I can subscribe to listening system events (Lock Screen/User log off/Device mounted/etc)? I try to use NSDistributedNotificationCenter to do it, but I can receive only own notifications =( This is the my test Console application: // //  main.m //  EventsListener // #import <Foundation/Foundation.h> #import <AppKit/AppKit.h> #include <iostream> @interface MyClass : NSObject -(void)subscribe; -(void)handleNotification:(NSNotification*)notification; @end @implementation MyClass : NSObject -(void)subscribe {     [[NSDistributedNotificationCenter defaultCenter] addObserver:self selector:@selector(handleNotification:) name:nil object:nil];     [[[NSWorkspace sharedWorkspace] notificationCenter] addObserver:self selector:@selector(handleNotification2:) name:nil object:nil];     [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(handleNotification3:) name:nil object:nil];     [[NSDistributedNotificationCenter defaultCenter] addObserver:self selector:@selector(handleNotification4:) name:@"com.apple.screenIsLocked" object:nil];     [[[NSWorkspace sharedWorkspace] notificationCenter] addObserver:self selector:@selector(handleNotification4:) name:@"com.apple.screenIsLocked" object:nil]; } -(void)handleNotification:(NSNotification*)notification {     NSLog(@"handleNotification: %@", notification); } -(void)handleNotification2:(NSNotification*)notification {     NSLog(@"handleNotification2: %@", notification); } -(void)handleNotification3:(NSNotification*)notification {     NSLog(@"handleNotification3: %@", notification); } -(void)handleNotification4:(NSNotification*)notification {     NSLog(@"handleNotification3: %@", notification); } @end int main(int argc, const char * argv[]) {     @autoreleasepool {         // insert code here...         NSLog(@"Hello, World!");         MyClass* mc = [MyClass new];         [mc subscribe];         [[NSNotificationCenter defaultCenter] postNotificationName:@"test notification" object:nil];         NSLog(@"Press enter to abort");         getchar();     }     return 0; } What wrong I does? Thanks!

Hello, Is in macOS exist system call which can resolve real path to file/directory for APFS? For example, in BigSur real path of /Users directory is /System/Volumes/Data/Users. So, I expect something like this: c++ std::string userFriendlyPath = "/Users/myuser1" const char* pRealPath = realpath(userFriendlyPath.c_str()); if (pRealPath == nullptr) _log.info("real path is the same"); // but in this case pRealPath should be == "/System/Volumes/Data/Users/myuser1" Thanks!

Hello, We have application which works fine on macOS 10.13-11.0 with x64 architecture and in Rosetta2 on ARM. But the same code rebuilt for ARM64 caused to SEGV on pthread_mutex_init.

Hello, We have plugin for installer and we use InstallerJS for additional checks before installation. Because of that when I run installer I see that message: This package will run a program to determine if the software can be installed. [Cancel] [Allow] And when I allow it my installer re-opens. It reproduces only on AppleSilicon (ARM64) version of BigSur (11.0.1 as well).

Hello all, I have found many articles how to distribute MDM profiles, but no one about using MDM profiles in applications. Is there some API or any documentation for that? For example, my application is already installed and now awaiting for MDM profile installed for all users. How I can determine that I need MDM profile installed? How I can determine path of this profile to read it in own application? Should I have some entitlements for that? Does any API exist for that, maybe? Thanks!

Hello!I try to read stdout and to write to stdin of a child process using method described here: http://www.microhowto.info/howto/capture_the_output_of_a_child_process_in_c.htmlIt's work fine for typical commandline tools, but it doesn't work for mount utility - password prompt everytime showed in my (parent) process. Why it happens? What is the difference between typical writing to stdout and password prompting in macOS?Thanks
