/ Stenfox Computing

Macs, PCs and drives, erased, tested and graded.

Each drive gets the erase method its media needs. Each Mac and PC is tested, checked for locks and replaced parts, graded and closed with a signed report before it goes back on sale.

Everything a computer goes through

01

Media-aware erase

22 methods, from NIST 800-88 Clear and Purge to DoD 5220.22-M, HMG IS5 and Gutmann. Purge uses the drive's own sanitize commands where supported, verified by read-back.

02

Lock and enrolment checks

Activation Lock and MDM on Mac. Autopilot, Intune and MDM enrolment on Windows. Flagged before the erase runs.

03

26 tests on Mac, 23 on Windows

CPU, memory, GPU, SMART, surface scan, battery, thermals, audio, display, keyboard, camera, ports and more. Touch ID, Touch Bar and Force Touch on Mac.

04

Drive health grade

SMART data and the surface scan give every drive a health grade before it is resold.

05

Mac, end to end

Apple silicon and Intel, from firmware restore to a ready-to-sell machine.

06

Resale insight

An A, B or C performance tier from CPU, GPU and storage results, plus flags for replaced displays, batteries and other parts.

/ OEM parts check

Every Mac, checked part by part.

Replaced displays, batteries, keyboards and Touch ID sensors are flagged and board serials matched, so a repaired Mac is never sold as untouched.

  • Display and batteryReplacements flagged before the Mac reaches grading.
  • Serials matchedLogic board and component serials checked against each other.
  • Priced rightFlags feed the grade, the A, B or C tier and the signed report.

Flags are indicators for your review before resale, not a certificate of authenticity.

/ FAQ

Frequently asked questions

Which computers does Stenfox Computing support?

Macs with Apple silicon and Intel, Windows desktops, laptops and all-in-ones, and HDD, SATA SSD and NVMe drives.

How many hardware tests run?

26 on a Mac and 23 on a Windows laptop. Touch ID, Touch Bar and Force Touch are Mac-only. Keyboard, trackpad, display and similar checks are guided operator tests.

Which erase methods are available?

22 methods, including NIST SP 800-88 Clear and Purge (Rev. 1 and Rev. 2), DoD 5220.22-M, HMG IS5, Gutmann, Schneier, VSITR and GOST. Every erase is verified by read-back and recorded in the signed report.

Does it detect Autopilot, Intune and Activation Lock?

Yes. Activation Lock and MDM on Mac, and Autopilot, Intune and MDM enrolment on Windows, are flagged before the erase so a locked machine never reaches the shelf.

Can it tell if a Mac has replaced parts?

Yes. Replaced displays, batteries, keyboards and Touch ID sensors are flagged and board serials matched. Flags are indicators to review before resale, not a certificate of authenticity.
