I have been running ESET for a few months now and it has been a great addition to my Macbook.. The product is small in size thus not intruding on anything else that I do. I used to run a much larger AV program that I have since removed from my computer I also feel much more safe regarding the potential cyber threats out there. I travel a lot and the thought of an anti theft function is very appealing, I cant wait to get it up and running. ESET makes an excellent product and I recommne dit to all MAC users out there!!
