05:05 <nicolas17> a while ago, decryption keys for M1 Mac iBoot were posted online, and some people here (including marcan) got to peek into iBoot that way

05:05 <nicolas17> but I don't think I have seen SEP keys before

05:05 <nicolas17> https://twitter.com/matteyeux/status/1668307736327598100 here's macOS 14 sep-firmware key?!

10:05 <marcan> nicolas17: I have the iboot keys up to 12.0 betasomething, that's how I found the new SMC charge threshold feature

10:06 <marcan> SEP though.... fun.

10:06 <marcan> wonder how that happened

10:17 <sven> huh, interesting. macOS sep kext are very verbose so I’m not sure if those keys will be useful. certainly good to have them though :)

10:17 <sven> I guess we can now claim that there are no hidden blobs even when using sep now ;p

19:34 <nicolas17> days ago there were some A15 keys published, including SEP from the start... almost certainly prototype device

19:35 <nicolas17> for M1 I heard the iBoot keys came from a prototype iPad

19:37 nimprod3l has quit [Ping timeout: 480 seconds]

19:37 <nicolas17> (same CPID = same GID key, so a hacked or prototype iPad Pro can be used to dump Mac keys and vice versa)
