What to do following the latest update direct from Apple?

Good morning, I have a MacBook pro mid 2012 with Sonoma OCLP 1.5 I accidentally did an update via the settings and it's difficult to use, I no longer have wifi and the display is catastrophic and slow. I tried to delete the post root patch then restarted to reinstall the post root patches but during installation I got a message saying "please ensure that you do not have any updates pending" then stopped. What should I do and in what order please?? I no longer have wifi but ethernet is possible if necessary. Should I completely reinstall sonoma with OCLP? Thank you.
