"Jailbreak" the T2 chip?
Did you find out some information that a jailbreak will affect what type of internal SSD is used?
The hardware controller for the SSD chipset is on the T2 chip, isn't it?
Could a jailbreak affect how the drive controller works?
Well yes I'm guessing that route might work, but then an actual jailbreak developer would have to spend some time on it and make a user-friendly tool for getting the job done. I certainly can't. I just ordered a 2TB iMac Pro SSD set on eBay.
Yeah, I have no idea if it would be possible, but since the T2 is one of the chips jail breakable with checkra1n, and the T2 handles the SSDs, I figured it could probably work. Having said that though, I don't think many people have actually tried to install the Mac Pro or iMac Pro SSDs by themselves, and I reckon there'd be even less people working on figuring out how to get it to work with a jailbroken T2. Furthermore, the iMac Pro is the only T2 Mac with removable SSDs that
isn't "user replaceable", and that was such a low volume device, I'm not sure anyone would really work on getting it to work.
Actually, I'm not sure what the point of the jailbreak is now other than to change the boot chime
