So far my corporate Mac antivirus has only blocked iOS apps that I personally built and it completely breaks the iOS simulator. It has caused me hours of headache and it regularly locks up my machine to the point that I have to restart it almost daily.

All of the things you mentioned can be stopped using far less intrusive methods than an always on, always scanning, antivirus.

The usual excuse given for requiring an antivirus is PCI compliance.
