I researched a color issue I had on my MacBook Pro off and on for five days, trying to figure out…read morewhy I had a glitch. Called Apple and got a Bot that lead me through all the steps I had already tried myself. I knew I was getting close to a solution, but lacked the confidence to try the seemingly last step. Only one thing to do: Call Mo at CaliPhonia. In one hour of consultation plus all my notes ad observations during the week, he was able to solve the color profile glitch issue and restore my MacBook Pro to its native color profile. He is worth every penny spent for his hands-on experience and vast detective skills. This is not the first time he has bailed me out of a jam in record time so I could keep doing my job as a photographer. He is like my paramedic for my Mac, and all is well because I know I have his technical support when things go askew. I highly recommend him. If you have a glitch... GO SEE MO!

I brought my iPhone 15 Pro Max in for a screen replacement, and he hooked it up with a great quality OLED screen. The display looks and feels brand new again--super smooth, bright, and works perfectly. Moe is super professional, honest, and stands behind his work. If you need your phone fixed right, this is definitely the place to go!

I went to Paul for a consultation for building my new PC. Paul gave me very good advices on what…read morecomponents I should buy. He saved me thousands of dollars on the PC components. He was also very helpful when I called him for questions and gave me a lot of good advices. At the end, I was able to complete my build and boot up my system successfully. The new system runs very quiet and fast - all thanks to the components recommended by Paul. I would definitely recommend anyone who wants to build a new PC to have an initial consultation with Paul, and even have him build a PC for you. Paul is very smart, intelligent, and knows a lot. He definitely is a passionate expert on the hardware stuff. Moreover, he cares about his clients and he wants each client to be successful on their computer stuff.

As I was checking to get repairs for my Laptop, I spoke to a couple of vendors via yelp and Paul…read morewas the rudest person in this business. Instead of providing me quote for the simple repair, he tried selling me a used laptop that he claims he gets from businesses, which at first I thought was a good choice. II asked him for the specs to understand what he is offering and if the laptop is new or used/refurbished,, he sends a rude reply saying that he had intuition it's not going to work. This is not how you run a business where you get rude response just to understand what you are agreeing to buying. Will not recommend him.

This seems to be a common problem among those who posted a review. My laptop just wasn't charging and I was getting an error message on my screen. Anthony Russo helped me by experimenting with several cords he had and he concluded it was the box of my charger that was bad. Fortunately he had one that worked for my laptop. He was able to diagnose and give me a new cord in less than half hour for $30. I'm glad to finally get this fixed. Anthony Russo has a kind demeanor and easy to talk to. I highly recommend him with any computer problems you have. The business is located on the 2nd floor of the building and even though there is supposedly a garage nearby, I was able to find street parking and fed the meter (4 quarters for half hour).

Screen wouldn't come on at startup and the entire thing would just power down. Back then I took it to an Apple Store where a genius told me it was out of warrantee and there were no guarantees they could repair, and if they did it would probably be less expensive to just buy a new laptop. I decided to just use my smaller MacBook Air and put the broken MacBook in a box at home. Flash forward to 2025, I noticed Fix that Mac while in Concord and decided to dig out the old broken MacBook to bring in. Josh said he'd have a look and give me a call with what he found. A few days later I get a text from Josh that he figured out the problem with the screen (a known graphics card issue) and also I needed a new battery as my battery was dead from being unpowered so long. We also decided to upgrade the hard drive so performance could meet almost 2025 standards and be able to jump up a few operating systems. After quoting me his estimates for the time plus hardware (which were incredibly reasonable) I gave the go ahead and my laptop was ready in another couple of days for pickup. Is my boosted 2015 laptop a match for the current 2025 line of MacBooks? Of course not! But it's running as well as my MacBook Air now and it's a great backup should I need more processing juice. Thanks, Josh! You work magic! Give this shop your business!

I had completely disassembled my $400 HP printer, put it back together and something went wrong and the screen wouldn't light up. They're not only found the tiny wire inside a very, very small cable that I have broken, they showed me a picture of it and gave me a complete tutorial. then they went on to explain why my printer wasn't working anymore. It had smeared printing because over five years, I've been using aftermarket toner on an HP printer. I then asked for a recommendation on a high volume printer for home use. That's in between category between home desktop and large office printers. They said they didn't know but they researched it and called me back a couple of days later with really excellent advice I took and purchased the printer they recommended! Then one day I was nearby installed a large projection system and didn't have a long enough power cable. I went in and explained and they gave me a 10 foot power cable for free. But most important these people are are very friendly as well as mean technical experts... But very humble about it and they really listen care about the customers. Wow!
