Other SATA Express cards: the small world of AHCI PCIe m.2 blade SSDs

[LightBulbFun]

interesting how they show up differently in System profiler, have you tried any of them with Tiger? I know traditionally its known that Tigers AHCI driver kernel panics when it comes to these AHCI M.2 blades, but im not sure how many have actually been tested so I wonder if theres a couple magical few that do work? 🙂

Seems at one point there used to be a 3rd party nvme driver that from what i can see did not rely on the 10.10 driver as a base. Creator was jimj740, maybe possible to reach out to him and see if he is willing to share source? I have PM'd him, not sure if he still checks macrumors though...

Claude is convinced the Yosemite driver can be easily patched to work: https://gist.github.com/Wowfunhappy/9bf6c0faf90febe498d1389cbb9468ed

I'm not going to be able to actually test this until the school year is over, but it seems promising.

Edit: Actually, I may not test this myself for a very long time, because I didn't realize how expensive high-capacity SSDs still are, so I'm not sure it's worth replacing my current setup which uses striped RAID SATA SSDs.

I can test this on a real Mac, but it was my impression Yosemite's driver only talks to Apple blades.

Cool, thanks, I don't have the hardware right now. I attached the kext itself so you don't have to run the Python script.

Please be prepared for the possibility it will kernel panic! You should probably boot with `keepsyms=1` so that if it does we can see why.

The attached kext has an info.plist edit which should, in theory, remove the vendor restriction.
