Had A MacBook Pro mid 2012 at this shop to restore back to Yosemite os from Sierra os was told be a day and would receive a call to pick up this was on a Thursday morning. The weekend comes and goes I never received a phone call I call to check on status I m told that he don t work on Mac machines and he subs them to another tech that only works 3 days a week and that he was too busy to call me to let me know that before the weekend come and that He would get it going and call in morning. Well once again no call so I call and he says it will be ready the next day and he will call. I finally get a call from him on Wednesday (6 days later) that it was ready to be picked up I come to pick it up and had to ask for power supply back and half the case that was protecting the machine. I get it open and booted up only to find out that the requested services were not completed. I asked for Yosemite and received Mojave and when the owner contacted me he even repeated what service I wanted done. When I talked to him about the issue he just quickly refunded my money. I do not recommend any services from this place very poor communication and does not complete task asked for. I took my Mac to another shop and had it back, fully functioning with the requested OS, within one hour.
