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 →
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 →
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 →
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.
A working example: when client mail goes to spam, the off-the-shelf answer is "buy a warmup tool." The evidence-led answer is to read the failed DMARC reports, find the one sending service that's misaligned, and fix the DNS so SPF, DKIM, and DMARC line up against the actual sending surface. Mail lands. No subscriptions added.
The same instinct produced our public DNS research platform at dnstool.it-help.tech, where we publish what we learn from the wire. Read the field notes →
