I’ve been a Mac user since ’92. They seldom have issues, but with the amount of illustration work I do, mine requires a thorough check-up from time-to-time. Brian took excellent care of updating as well as backing up and deleting the junk from over 10 years. And I know I can always get in touch with him and that, in many cases, he can walk me through any problems with my Macs. I’m happy to refer him to both my Mac and PC user friends and associates. I highly recommend that you have hime set you up with a back-up system, becuase sooner or later, you’ll, lose your info.
