APPLE HARDWARE DIAGNOSTICS KEY?

You can use the Apple Hardware Test (AHT) to diagnose issues you're having with your Mac's hardware. This can include problems with your Mac’s display, graphics card, processor, internal sensor failure, memory, and storage. You can use Apple's Hardware Test to rule out most hardware failures as the culprit when you're trying to troubleshoot problems you're experiencing with your Mac.

From time to time Apple’s hardware can fail, you end up spending hours and hours try so sort problems that don’t exist sometime spending money on the wrong hardware. the most common hardware failure is random-access memory (RAM). The Apple Hardware Test can check your Mac's RAM and let you know of any issues with it. With many Mac models, you can replace faulty RAM yourself, and save a few pounds in the process.

About Apple Service Diagnostic

The Apple Service Diagnostic application is designed to run both EFI and Mac OS X tests from an external USB hard drive. Apple Service Diagnostic (EFI) runs low-level tests of the hardware directly and does not require Mac OS X, while Apple Service Diagnostic (OS) uses Mac OS X to run tests.

We do not supply the cheap nasty slow USB Keys, even though you only generally need only 4GB our keys are Fast USB 3.0 & 3.1 Keys of 32GB in size which is what you are paying for, they are much more useful and can simply be formatted and re-used afterwards to backup your important data or whatever else you might need.
