Hello

I am new to Cocoa. How can I make a metronome in cocoa? I tried using
NSTimer but it doesn't work - its very inaccurate. Any ideas?

Instead of relying on the timer to keep track of time, you should simply use it as an updating callback. Then in the timer callback, call [NSDate timeIntervalSinceReferenceDate] and subtract that from the last time that the callback was called. That is the duration of time that has past since the last callback. Now you know what you need to render. Good luck!
