Crimson Research Inc. is a 100% Macintosh-only consulting and service firm. We specialize in Apple products and strive to serve the Macintosh community better than anyone else. There are other companies that profess to fix Mac problems, but that usually means they have PC technicians who "know a little about Macs". Our talented Macintosh consultants have more than 40 years of combined Macintosh experience. At Crimson Research, we're serious about delivering workable and proven Macintosh solutions.

Crimson Research is in tune with Apple, and we work hard to stay on the cutting edge of the world of Macintosh, so you don't have to. We are Apple Developers, which gives the Crimson Research team advance access to Apple system updates and future releases of the OS, like Leopard. We install, test, and experiment with the latest [and future] releases of OS X server and client before they are released to the Macintosh community.

Our business philosophy is simple: Be there for our customers when there is a Mac problem. We answer our phones quickly, and when you call, you will be talking to someone who can answer your question. If you have a Macintosh need of any kind, whether it's consulting, service, sales, training, upgrades, or networking, we can help!
