We solve tech problems. No monthly retainers.
Apple-centric IT, deep-research diagnostics, systems & networks — La Jolla concierge for greater San Diego.
What we do
Mac & Apple Ecosystem
macOS, iOS, iCloud, and Apple Mail diagnosed at the system level. Storage, sync, performance, and migration handled correctly the first time. Learn more →
Cross-Platform Systems Engineering
macOS and iOS lead our work, but Unix, Linux, and Windows get the same scientific care — a system is a system. From shell scripts to file servers to mixed-OS environments, we engage the problem, not the logo. Learn more →
Wi‑Fi & Network Engineering
Bespoke wireless and wired networks for large homes, estates, and small offices. Cat6A/Cat8/fiber backbones, mesh design, and dead-zone elimination using measured RF data, not guesswork. Learn more →
Email Deliverability & DNS Forensics
We rescue email from spam folders by aligning SPF, DKIM, and DMARC against the actual sending surface — including SPF macro expansion checked against RFC 7208 §7.4. Learn more →
Trust signals
- 27+ years in the field, across macOS, Linux, Windows, network architecture, and DNS.
- High-profile clients in entertainment, legal, restaurant, and medical sectors. Discretion comes standard; logos do not.
- Federal A+ DNS posture on our own infrastructure — the same standards we apply to client domains.
The Method
Deep-research diagnostics — the principle is simple: we measure before we fix. A doctor runs labs before prescribing; we read the evidence the system is already producing before we touch a config.
Most IT support pattern-matches symptoms to the usual fix and hopes it sticks. We start one step earlier: capture the primary evidence — packet traces, mail headers, DNS responses, system logs, RF readings — and reason from there. The fix is whatever the evidence demands, not whatever the script says.
If you've ever called for tech support and bounced through tiers trying to reach someone who could both understand the problem and actually fix it, you already know why this matters. The diagnostic step is the part that gets skipped — and it's the part that decides whether the fix holds.
A few working examples.
Computer running slow. The off-the-shelf answer is "you need a new computer," or a monthly "PC speed-up" subscription. The evidence-led answer is to open the system's task monitor — Activity Monitor on a Mac, Task Manager on a PC — and look at what's actually running. Usually it's a forgotten cloud-backup tool from three years ago pegging the disk, or a browser extension chewing through memory. Uninstall it, the computer is fast again.
Printer that "stops working" every few weeks. The off-the-shelf answer is "time for a new printer," or worse, a managed-print contract. The evidence-led answer is to read the printer's own log: it's losing its IP every time the router reboots overnight. While we're in there, we usually find the alarm panel, the cameras, the access control, and the VoIP phones all hardcoded with static IPs that were chosen by hand at install time — a recipe for silent collisions when something else on the network grabs the same address. The right pattern is usually the opposite: leave devices on DHCP and reserve their addresses by MAC at the router. Set once, no more address fights.
Slow Wi-Fi. The off-the-shelf answer is whatever the recommendation was — almost always a mesh kit. Mesh without a wired backbone is a workaround for not having infrastructure: each node repeats the signal of the node before it, sharing the same airspace and stepping on its own broadcast. Sometimes the fix really is simple — your router lives in a closet behind a metal filing cabinet and moving it twelve feet solves it. More often, the real fix is to do it right once: pull actual Ethernet to the spots wireless needs to live, and feed each access point with a wire. Wires are what make wireless excellent.
Email going to customers' spam folders. The off-the-shelf answer is to sign up for a deliverability service or an inbox "warm-up" subscription. The evidence-led answer is to look at what's actually sending mail in your name: usually it's an old appointment-reminder app, or an invoicing tool from three providers ago, that was never properly authorized at the DNS level when it was added. Authorize the ones you still use, shut off the ones you don't, and mail lands. One afternoon of cleanup, no recurring fee.
