I tried BOOL ImageMagick = [[NSFileManager defaultManager] fileExistsAtPath:@"/ImageMagick*/" isDirectory:YES];

You're calling that wrong, the second parameter expects a pointer to a BOOL, not an actual BOOL. The correct syntax is:

BOOL directory; BOOL exists = [[NSFileManager defaultManager] fileExistsAtPath:@"/ ImageMagick/" isDirectory:&directory];

But anyway, you're probably best getting the directory contents of where ImageMagick should be installed and running through it. I'm not familiar with ImageMagick; I don't even know what it is! But you should bear in mind that if it's relocatable you'll want to check all the possible locations.

Take a look at NSSearchPathForDirectoriesInDomains() in the docs.
