Submitting a security bug report to the Chromium project was a delight compared to submitting one to Apple. It was obvious that the engineers working on Chromium cared about the problem and were competent. On the other hand, I mightaswell have been reporting the Apple bug to a brick wall or a black hole.
Odd use of the word "competent", you implying Apple personnel aren't competent because they didn't send a message saying "thank you" with gold stars all over it?
