After a software update our Apple TV tanked, displaying an error message and referring me to an Apple support page explaining how to restore it. I tried to do it myself, but being a senior citizen without a shred of computer savvy, I botched it and was totally at a loss. Fortunately we contacted Carbon Computing, who sent Gavin to our home. Professional, friendly and competent, Gavin solved the problem well within an hour, and provided help on other small matters as well. We've come to depend on Apple TV (we watch classical and jazz concerts from all over the world) and love having it working again. Thank you, Carbon, and thank you, Gavin!
