We provide customized support plans ranging from a few computers to networks with hundreds of Macs. If you happen to have a few PC’s on your Mac network, we won’t hold that against you. We have experience integrating Windows clients and setting them up to utilize all of the services OSX server provides.

Specific areas of support:



computerDNA is an Apple Premium Service Provider offering both warranty and non-warranty break/fix repair service at our location in Blue Ash. We run our service department on a repair-queue system, based on a first-come, first-served system. We charge a minimum bench fee of $100 for our time invested in diagnosis and triage. This $100 will be applied to any subsequent work that is done on your repair, including our data services. Unlike the Apple Store, we do not offer while-you-wait bar appointments or consultations, but we do offer an average turnaround time of 2-3 business days. You do not need to book an appointment but if you would like to let us know you are coming you are welcome to book one through Apples website here After the repair is complete in-house, we offer an option to deliver your Mac and set it back up at your site.

Our technicians can provide and install upgrades, updates, and system software on your Mac. Give us a call to discuss RAM, SSD upgrades or possible system replacement. We will evaluate your situation and make the recommendation that makes sense for your needs and budget.

Data recovery on your Mac is our specialty. If for some reason your data is not backed up, our technicians are experts in getting your data from failing or corrupt drives. If we are unable to get your data, we partner with hardware recovery experts who have excellent success rates with data clean room recoveries.

Guardian Program


For years, the computer support industry has operated on what’s called the “Break-Fix” model: a computer user has a problem, they call a computer consultant, and the consultant comes out and fixes the problem. This is a reactive process, meaning that something that might have been a small problem initially, often ends up as an enormous (and more costly) issue by the time the computer consultant arrives on the scene. If only we could have known about the issue when it first started… with Guardian, we can!

Our Guardian program provides monitoring, maintenance, and security services which help us keep track of your computer’s health and well-being, and spot potential issues before they become full-blown problems. To be clear, Guardian only monitors computer health information. We neither see nor collect personal data of any kind. Your privacy and security are crucial to us, and in fact, data preservation is one of the fundamental advantages of Guardian.

When a potential issue is spotted, we alert you via email with specific information about what is happening with your computer, as well as the steps needed to repair the issue at hand. According to your needs, our programs can also run appropriate maintenance routines, complete small system and software updates and patches, scan for and quarantine malware and adware, and repair some common errors.

In addition to our Guardian program, if you need troubleshooting or training with your Macintosh computer, CDNA can help. We’ll come to your home — the place where you’re most comfortable and where you regularly use your computer — and get things working again, develop a plan of action, or teach you what you want to know about using your Mac.

We invite you to review the information about each of these programs (Guardian, Guardian +,) and decide which one is the best fit for you!

The CDNA Guardian program provides 24/7 monitoring of your Apple Macintosh computer’s basic health. If there’s a problem, we’ll notify you immediately so that you can take steps to remedy the problem. That remedy may be as simple as plugging in a Time Machine hard drive (if you’ve forgotten to make a backup in a while) or as serious as having us come out for onsite repair visit. Either way, the good news is that with Guardian we can finally be proactive and catch problems when they’re small. Guardian is just $9.95 a month or if you pay the year in advance, only $99 saving you 20%. We also have significant
discounts if you sign up for the family plan.


Guardian+ gives you the same 24/7 monitoring as Guardian plus it adds maintenance, security and the ability for us to schedule remote troubleshooting sessions where we are able to take control of your Mac remotely and resolve most issues. Guardian+ is designed for users who want to spend their time using their Mac; not managing the apps required to update, fix, and protect it.

Among other things, Guardian+ runs the appropriate maintenance routines, upgrades third party software & OS, scans for and quarantines malware and adware, fixes common disk errors, tests memory, repairs permissions, and more. And it does all these things when your computer is idle—when you logout at night, for example— so that you’re not interrupted in the work you want to do.

Guardian+ software updates are particularly helpful for a lot of people. Most people don’t have time to read all of the details on what the updates are about nor are they sure if they should be applied or how to even apply them. Guardian+ makes the updating process worry-free. Our software keeps your system updated. Updates are only applied after being vetted and held for a period of time during which testing takes place. Security updates are the exception; these are pushed out immediately.


Guardian does NOT have access to personal information stored on your computer’s hard drive(s). Guardian alerts will be sent to ComputerDNA staff but will only be acted upon during normal business hours. We oer no guarantee as to anticipation of or limiting liability of computer downtime. Guardian should be considered an extra tool in the IT toolbox to assist ComputerDNA in providing improved,proactive service and response. It is the responsibility of the CLIENT to ensure that the Guardian software is installed on their computer. Our Guardian services are not designed for training, nor do we provide support for financial or project management software. For training, the in-house support provides our clients with the best experience. Remote access to your computer is only established upon client approval and by appointment. Remote sessions are billed at $100 per hour and in quarter hour increments.

About Us


CDNA-3       CDNA-1

computerDNA was formed in February, 1997 to provide comprehensive support to Macintosh users in the Cincinnati area. Our first “office” was a section of a warehouse in Lockland in which we had to turn the furnace off in order to hear phone callers. Six long months later we moved to Blue Ash where the furnace is now much quieter. A little less than eighteen months later, we added ‘Apple Service Providers’ to our list of services. Since then we have grown to a client list that includes: Cincinnati Enquirer, Cincinnati Magazine, Ethicon EndoSurgery and many more. We have formed strategic alliances with many PC consulting firms, and can supply expertise in any cross-platform circumstance. We are proud of our accomplishments thus far, and look forward to helping current and future Mac users throughout the life of their computer.
