So far, there haven't been any major changes toward the release of OCLP 3.0.0 Nightly. That will likely take some time, and everyone is eagerly awaiting it.
However, there have been small improvements by the developers, such as the addition of more unsupported Macs to the OCLP list (Unsupported Host OS). At least, that's how I've perceived it.
Unfortunately, my iMac 18.3, which I'm currently using for Tahoe-tests, hasn't been added to this list yet.
Does anyone know when this is planned?
