On-site IT Services San Diego (La Jolla) | IT Help San Diego
Seven service pillars, organized by the problem they solve. Across all seven, the model is the same: you bring a mission, problem, or research goal; we engage, solve it, and bill only for work performed. No retainers, no lock-in, no padded hours. This structure gives clients access to senior-level engineering when needed, without an ongoing contract.
Mac & Apple Ecosystem
System-level support for macOS and iOS, focused on the diagnostics that require direct log access and command-line tooling: kernel-level disk pressure, iCloud sync collisions, Spotlight index corruption, and the long tail of post-migration breakage. We read system logs directly rather than guessing from symptoms.
- Mac performance & troubleshooting — startup disk pressure, iCloud sync failures, application crashes, and post-update regressions.
- Apple Mail on macOS and iOS — IMAP/SMTP setup, certificate issues, signing/encryption, and recovery of broken local mailboxes.
- Time Machine and backup strategy — verified restores, not just green checkmarks.
- Cloud storage — Dropbox, iCloud Drive, and Google Drive setup with sane permissions.
- Disaster recovery planning — documented procedures, not improvisation.
Wi‑Fi & Network Engineering
Bespoke wired and wireless networks for large luxury homes, estates, and small offices. We use Cat6A, Cat8, and fiber backbones, and we design from measured RF data rather than vendor brochures. You buy gear directly from the source; we are not a 40% reseller markup, which means we are free to recommend the right hardware rather than the hardware we are channel-locked into.
- Wi‑Fi mesh design and dead-zone elimination based on actual site survey data.
- Network setup and security for home and office.
- Infrastructure planning for new construction and remodels.
- Static-IP configuration, port forwarding, and double-NAT remediation.
- Network printer sharing that does not break on every macOS update.
- Switch, gateway, and firewall programming, including lost-credential recovery.
Email Deliverability & DNS Forensics
We resolve email deliverability and domain-security problems by going to the wire. We read mail headers, verify DKIM signatures byte-for-byte, and check SPF macro expansion against RFC 7208 §7.4 instead of trusting a green checkmark in a vendor dashboard.
- Email migration and setup, including Google Workspace.
- DNS edits and configuration for MX, SPF, DKIM, DMARC, DNSSEC, and BIMI.
- DMARC enforcement to
p=reject, staged carefully through monitor and quarantine. - Website and domain recovery when access has been lost.
- Public research platform: dnstool.it-help.tech — the same diagnostic depth we apply to client domains, available for anyone to use.
Cybersecurity & Ethical Screen Sharing
Endpoint defense, mobile device security, and remote support that respects client control. Sensitive engagements are handled with discretion appropriate to legal, medical, and high-net-worth contexts.
- Endpoint security for macOS, Windows, and Linux.
- Mobile device security for iPhone and iPad.
- Data privacy and discreet advisory for sensitive technical situations.
- Ethical screen sharing — you, the client, always initiate and approve access. We do not maintain standing remote access to your systems.
Forensic Data Extraction
For law firms and legal professionals: structured extraction of email and iPhone iMessages into court-admissible, timestamped PDF reports suitable for litigation and eDiscovery. The work is done on-site, on your equipment, so the data never leaves your office. On the first engagement, we document the workflow and train your staff so your firm can run future extractions in-house, without ongoing dependency on us. If you prefer, we can also continue handling matters case-by-case.
Cross-Platform & Systems Work
macOS and iOS lead our work, but Unix, Linux, and Windows get the same scientific care — a system is a system. We engage the problem, not the logo. The same instinct for analyzing logs, tracing packets, and deducing from evidence is applicable regardless of the prompt.
- Shell scripting and automation — Bash, Zsh, and PowerShell for repeatable, auditable operations instead of click-by-click drift.
- File servers and shared storage — SMB and NFS that hold up across macOS, Windows, and Linux clients without permissions roulette.
- Mixed-OS networks — identity, DNS, printing, and file sharing that behave the same on every desk, regardless of operating system.
- Server diagnostics — Linux and Windows server troubleshooting from the logs up: systemd, journalctl, Event Viewer, and the boring fundamentals that vendor dashboards skip.
- Cross-platform migrations — moving users, data, and workflows between macOS, Windows, and Linux without losing fidelity along the way.
Managed Agent (Opt-In, $50 per Device)
An optional month-to-month maintenance and security layer that keeps your devices current between consulting sessions — across macOS, Windows, Linux, iPhone/iPad, Android, and ChromeOS. $50 per device per month, no managed service contracts.
Once enrolled, the agent handles automated OS updates and application patching, security policy enforcement, centralized device visibility, and remote support access. The goal: spend live consulting time on actual problems, not routine maintenance.
IT Consulting Sessions work stays on the same transparent break-fix on-demand billing.
Your devices will have the same advanced monitoring agent trusted by top managed service providers — at a fraction of the typical cost. Platform: ManageEngine Endpoint Central Cloud — Security Edition.
