Came in for my MacBook Pro. 2011. Very slow, restart needs to be done consistently. Kal came over and assisted me. Turns out I need to update the system as it is moons behind. Since I'm extremely tech challenged, he explained and helped me with everything. Next up asked about my iPhone as it would rapidly change screens and type on its own. Sure enough there was an issue and my iPhone was needing to be replaced. Great experience today.
