sounds like the metal library package...I can just repeat myself...users, that cannot connect their machine(s) to the internet via ethernet need to download and install it from the OCLP Github page manually before updating to Sequoia...after the update to Sequoia you most probably do not have a wifi connection and when doing the patching OCLP cannot load the metal library package which is however essential for most of the unsupported machines now...
Thank you again for this!
I got it working. My device's wifi. I've no idea how!
I went to the Metalib repo. [Thank you for the link!] I downloaded the version that's right for my 15.0GM environment. Before doing the install I went to the /Library/Application\ Support/Dortania/MetalibSupportPkg directory. In it I found a directory bearing the same version number as what you instruct me to install -- in other words the correct version has been there the entire time?!?
So I go off on some tangents. First I install the latest version in the repo overall. It's a version for macOS v15.1 beta.
Then I delete the directory for the *proper* Metalib version.
I redo the root patching.
Still, no wifi.
I reinstall Metalib version that's proper for macOS v15.0.
I redo the root patching.
Stlil, no wifi.
I see in the menubar a darkened (active) wifi graphic. But, in Safari, I cannot load webpages. I look at the 'details' screen for my wifi connection. I see that the 'Limit IP address tracking' button is turned ON. I turn it off. Lo! and behold! Wifi working again.
In this case, I think my issues attributable to the privacy setting??
Year after year, I hate Apple software more and more. Security theatre, privacy emphasis leading to complexity and/or bugs.
THANK YOU, kind readers, and especially
@luckyduke23, for this advising!
