Question

I’m doing an app that changes the Trash-icon in Mac OSX… so far I got:

- (IBAction)install:(id)sender {
NSLog(@"Installing..");
NSLog(@"Trying to move file..");

NSString* src = @"/Users/myuser/Desktop/dashboard.png";
NSString* target = @"/System/Library/CoreServices/Dock/Contents/Resources/tester123.png";
NSError* error = nil;

[[NSFileManager defaultManager] copyItemAtPath:src toPath:target error:&error];

if (error) {
    NSLog(@"%@", error);
    NSLog(@"%@", [error userInfo]);
}

}

I’m getting the error:

The operation couldn’t be completed. No such file or directory

I believe it’s because that Dock isnt a normal folder, but a package? How do I work around this? Or is there a better way to change the trash-icon?

Answer 1

Change your target to this (Dock becomes Dock.app):

NSString* target = @"/System/Library/CoreServices/Dock.app/Contents/Resources/Sample.png";

You need administrative rights, otherwise you get this error:

 "The operation couldn’t be completed. Permission denied"

This command works perfect in Terminal (conclusion: the path is correct).

sudo cp /Users/Anne/Desktop/Sample.png /System/Library/CoreServices/Dock.app/Contents/Resources/Sample.png
