Top 2 Windows -> Intel Mac | Bottom Row -> PPC dev/disk6 & /dev/disk7 -> For Intel Macs | /dev/disk8 -> PPC iBookĪt first I saw this and the whole Apple Partition Map thing confused me at first, I didn't think EFI could boot partitions with that scheme, but it seems like Apple's EFI must be able to. The Intel ones are most definitely EFI applications. You guessed right it seems, I found some links for a few Intel Mac AHT dmgs from this blogspot page, and then I also found some PowerPC ones on this Apple page Nickenzi wrote:I would guess it is just an EFI application. (but again what's up with the UI being so old-school?)Īnyways, does anyone have any knowledge concerning the make-up of this tool? It could also be it's own thing, written specifically to test the hardware, and if so it would be really interesting to mess around with. It could be Darwin-based, but if so, what gives with the legacy UI? (The about box says copyright 2000-2012, and 2000 seems to line up with the darwin bit, also the build number also looks MacOSX-ish in nature.) Visually it hints at Mac OS 9, but seeing as this is an Intel Mac, It is 99.99% likely that that is not the case (Why would Apple port their old, unsupported OS to a completely different platform and then write drivers for it to support all this modern hardware?) So the question is, what operating system is underneath this utility? (I've also seen a different diagnostic utility run on my mac at my local apple-related repair place, what had the platinum UI, with OS9-looking windows) When loading, its boot screen is this logo, with an OS 9-style purple progress bar underneath:Īnd then here's a couple screenshots taken with my phone:Īs you can see, this has the Platinum UI used in Mac OS 8/9 & Rhapsody, up to OS X DP2 Naturally, there's plenty of information on how to use it/what its for, etc, on the internet.īut after seeing the interface of it,I had some questions regarding what it actually is OS-wise. It is accessible by holding down the "d" key when you turn on the mac. So, in case people don't know, in pre-2013 macs there is this feature which runs some hardware tests. ![]()
