My computer crashed after trying to install the El Capitan upgrade on my Macbook Pro. After going through hours of tech support with Mac via phone, they told me my only choices were to wipe my hard drive clean and start over (not a viable option for me) or contact a data recovery service (I just knew this was going to be incredibly expensive even though "they could only save a few things"). A google search lead me to Thumbtack, where I input what I needed. Mac Doc responded within minutes and gave me a very reasonable price quote. After quickly researching his business and seeing quotes come in from other companies (his was the best), I hired him for the job. Within a few days I had my laptop back and he saved my life! I am so grateful to Mac Doc for his honest and outstanding work ethic. I cannot thank him enough!
