In a test volume, I upgraded my MBP6,2 from Sequoia 15.5 -> Sequoia 15.7 Beta (RC?). I applied post-install patches for non-metal Nvidia Tesla and Wi-Fi using OCLP 2.4.0 built from source as described below. Posting this with Safari 18.6 (did not upgrade Safari yet). So far, so good. Amazing.

Building OCLP for Sequoia 15.7 Beta
As noted earlier in this thread and at the time of this post, OCLP cannot find a suitable KDK for patching 15.7.
This is because OCLP has restrictions on the suitable KDK version (for good reason, I'm sure). Using
@hvds 's trick
here, I relaxed the OCLP KDK restrictions and built OCLP from master source.
With the modified OCLP, KDK 24F74 is considered to be a suitable match and patching is allowed.
Note that I am sure OCLP Devs have good reason for their chosen KDK version restrictions. Overriding the restriction is good for testing and experimentation, but it will be best to wait for the release of a suitable KDK by Apple.
