All 3 of the techs that came to my home were knowledgeable and answered all my questions– Core Solutions did an excellent job.

My iMac desktop was slowing down and Ricky and John replaced the control board with a Samsung board that has increased the speed of downloads by about 8 fold.


Commercial Real Estate Developer, El Dorado Hills CA

CoreSolutions is consistently responsive, knowledgeable and so helpful with all things tech. Cannot recommend their services highly enough! Especially for any Apple products.


Residential, Sacramento CA

My computer sends a notice to CoreSolutions so they know when something’s wrong before I do. Then it’s solved quickly and usually without the need for a personal visit. I’ve always been very satisfied with their service.

Promptly set up an appointment within an hour after my request, worked on my issue remotely, and fixed the problem. Very pleased!

Residential, Elk Grove CA

I found CoreSolutions and spoke with John about my dinosaur MacBook Pro that I was using for my Coffee business. I mainly worked with John at CoreSolutions and he provided great advice for my MacBook Pro to updating it to Mojave to using QuickBooks 2020 for Mac. My business was very unorganized and John had helped me rebuild my business by using cloud services. I would highly recommend CoreSolutions to anyone in Sacramento!


Coffee Business Owner, Sacramento CA

Simply the best. Thank you for making my life easier.

John was easy to schedule with, knowledgable and professional. He advised me on what replacement part to buy for my MacBook Pro and installed the part quickly. I will definitely use his services again, and highly recommend to anyone needing Apple advice or computer assistance.

Pediatrician Healthcare, Sacramento CA

The CoreSolutions team is amazing for all tech related needs.

Hands down, CoreSolutions offers the best tech support experience with their knowledge, agility, transparency and willingness to help. I mainly worked with John; he has been a great resource from the start- understanding my tech needs based on what I use and how I use it, seamlessly setting up the services, instantly notifying me of potential issues and meticulously walking me through the resolution process. I barely lifted a finger from my first interaction with CoreSolutions as John and his team took care of everything, with speed too! When it comes to Apple tech support, John not only knows what to do, but he is a model of how to do it.

Residential, Twin City CA

I was immensely satisfied with the level of service I received from CoreSolutions. John was recommended to me by a good friend. I sent a text on Tuesday evening outlining my problem and received a text early Wednesday morning stating he could assist me with my problem and setting up a meeting for a few hours later. John was very patient and also clear and concise about each step I needed to take. He explained what he was doing each step of the way. He also fixed my printer problem. We were done in less than an hour and all over the phone. I would highly recommend John and CoreSolutions.

Residential, Fair Oaks, CA

Rebuilding Adobe Lightroom Catalog, and migrating failing external drive to a Synology

One of the toughest challenges that the photo software Lightroom can present is moving thousands of files from failing external drives to new drives and have Lightroom still be able to find your raw files. John Le of Core Solutions moved 30,000 of my files to new drives and linked all of them back to Lightroom. I don’t know anyone else who can do that. In addition, John and Ricky gave me the information and advice I needed to select the new hardware I needed to replace the failing drives, and they installed the new setup for my photography business.


Photography Business, Sacramento, CA

Fast & professional

Provided access to my deceased wife’s lap top & iPhone without passwords


Commercial Real Estate Developer, El Dorado Hills, CA

Thorough, Knowledgeable, and Sociable

John knew exactly what to do to fix our issue. Whenever we would run into a roadblock in the process, he always had an alternate plan to arrive at our solution. He is also very easy to talk to and is personable, which is important in many ways as no one wants to troubleshoot for an hour with a wall! John took the time to reach out to me the following day, just to make sure our issue did not come back. Getting set up with CoreSolutions was a breeze. Making appointments, changing/cancelling appointments, paying an invoice, everything involved with CoreSolutions is so simple. Although, no one looks forward to future tech issues, I am relieved that I found John as a resource for when these inevitable situations arise. Highly recommended!


Real Estate Executive Assistant, Sacramento, CA

Great company to work with

John is the person that I have mainly worked with. John is a Superstar! He is friendly, brilliant and patient. The other members of this firm are also terrific but I haven’t as much communication with them as I have John. John has made my life soooo much easier. Thank John. You really are a master at your profession.
