BIOMAC  I bought this yesterday and installed it. I found the email could not search in entire messages. the printer was not working, which suggested me to contact the manufacturers. several third party softwares asked money for upgrading and previous free ones were not free any more. I did not feel my computer faster. I simply wanted to pay somebody to get rid of this copy from my computer, which drove absolutely crazy. this is the reason I am writing here. hopefully, it is helpful for those people who are hesitating at this moment.
