Above and beyond incredible service. Luis is old school, he looks out for you and has your best…read moreinterests at heart. I went to Luis for screen repair bc my laptop fell onto the floor on the side and the screen cracked, and blacked out with dead pixels on the screen. Luis repaired it for me so fast with incredible turnaround time within days. List of why Luis goes above and beyond: 1. Cared about saving me money whenever possible and was very transparent about prices, talked me through details and options for replacement screens and gave pros and cons of each while comparing prices. He sent screenshots of prices and receipts as well as FedEx tracking. (As an aside, I mentioned I might Lyft to his place to send the laptop and he said 'don't do that, so expensive, take MUNI and save money!') 2. After receiving my laptop, he also saw my right speaker had bad sound (I've been meaning to get this fixed for a while and have been putting it off) and offered to fix it himself. He was going to do it for an additional $50 then later just charged me $25 bc the speaker he found wasn't "perfect" according to him but to me it sounds great haha. This saved me so much instead of going to Apple without warranty which would have been at least $200 bc from what I read, they usually insist on replacing the entire "top case" and not just single speakers. Wow, thanks Luis! 3. I am badly organized and don't maintain my storage well; when I went to pickup he gave me many tips on what to fix and how to free up more storage, then organized my desktop for me in front of me. Thanks Luis! His communication is also top notch, very fast response times, very detailed texts. He's absolutely fantastic. You are in good hands if you go to him.

luis's efficiency, short turnaround time, and thoroughness are truly admirable thus i'm thankful…read morethat he was able to repair my laptop so quickly. context: i spilled half a glass of room temp water on my macbook pro (april 9). april 11th (4/11), though my laptop can turn on + all of my data was still there, the keyboard and trackpad no longer worked. timeline: i contacted him through his website on monday (4/13) afternoon, then again on yelp monday night (due to my anxiety and urgency). luis called me wednesday morning (4/15) for details and the price cost to repair. we scheduled for me to drop off my laptop the next day (4/16), where i walked him through what had happen to the macbook and he walked me through what he was planning to do to fix it, as his success rate for liquid damage repair is 70+%. luis contacted me again later on the same day (4/16) via text message with photos + explanations with what had happen after opening up my laptop AND that the laptop was fixed & ready for pick up! after checking everything is fine/ good to go, i picked up my repaired macbook on friday (4/17). price: it was a $100 nonrefundable deposit to check if the laptop is fixable (paid on 4/16). $200 for labor + $20 for parts (lid angle sensor and 1 usb-c port) that needed to be replaced (paid on 4/17). total for my macbook repair was $320. sincerely appreciate the speedy fix and def reach out again for future macbook repairs/replacement parts.

We inherited a Macbook Air from a former employer that was overloaded. After trying various…read moresuggestions from Mac forums and downlowning MacClean, I was unable to get it cleaned up. Jimmy came out to our place near Washington D.C. and helped us get it up and running. Plus he had enough time to look at another iMac for us. Now both macs are updated to the newest OS. Thanks Jimmy.

I emailed about a dying battery in my MacBook Air, and received a very prompt response within the…read morehour. The day of my housecall, it was POURING, and Jimmy was on time, prompt, and focused right away on replacing the battery and doing some cleanup for my machine. He has a 1 hour minimum, and the battery replacement wouldn't have used it, so he suggested the tune up, which I agreed was a great idea. He found some unused apps and out of date software, and prior to the appointment (almost forgot!) he recommended I update to the latest OS software. When I mentioned that a prior upgrade had resulted in an unusable machine and I'd had to restore a backup to fix it, he said to do the upgrade before his appointment, and if something went wrong, he'd be able to help me out. The upgrade went fine, but I was a lot more confident about it knowing I had help on the way. I found JimmyMac after looking up reviews of the local Genius Bars in my area - even though my machine is way outside of warranty coverage. The reviews were so poor that I looked on other parts of Yelp. Jimmy is an outstanding support and repair tech, and I'm so relieved I found him here. Excellent customer service, punctual and careful, and very attentive.
