I just updated to MacKeeper Version 3.8.1 (1144) and why did I wait so long? I purchased the MacKeeper Premium+ 24-month plan, and now I have awesome peace of mind! I chatted with a "Live" and very patient Tech/Rep and he walked me through the entire process. I'm not a computer tech, but I'm on my computer all the time, so if you are like me and the other 90% of mac computer users that depend on their computer for income, you need to update now. Don't put it off like I did. My suggestion is to purchase the 24 month plan because the price comes way down, and you have TWO YEARS of hassle free wellness for your Mac. Thank you MacKeeper support team, I really appreciate your expertise, and am a very happy customer.
