The negligent implementation is clear from the very existence of this post, as well as a former one describing how Apple’s buggy code caused months of headache, brand damage and extra support costs last year.īefore you ask, I have reported these things to Apple countless times, even offered my help, but they continue to show zero interest in cleaning up this steaming manure pile. b) It grossly violates the “principle of least privilege” by granting apps access to resources they have nothing to do with, and even don’t need at all.
