Managed MacBook Pro stuck on macOS install after factory reset

Hi Apple Folks,

I worked as a freelance video editor for a medical company for several years when the pandemic hit. My wife and I were forced into early retirement and we moved out of state but I continued working with this company. However, since then the company went out of business but the computer I have is still controlled by their Remote Management connection. Yesterday I tried to change my Screen Saver setting so the computer wouldn’t go to sleep and I found I couldn’t do it because I would have to change the profile…which I couldn’t because…ya know…remote management ! :-).

So, clever computer guy I am, I figured I’d just erase the entire computer and install the latest OS at the same time. I backed up all by stuff onto an external drive, went into Recovery Mode on the Mac and started the process of installing Sequoia… everything was going great until the question came up about the remote management access again… I clicked the ‘connect to server’ in hopes the ghost of access past would still be there… but, alas, nobody home and now I’m stuck in an installation circle of ****!

Any advice?? Aside from setting fire to the poor beast or tearing it apart and replacing it’s hard drive…but I fear that wouldn’t work either… the remote manager may be lurking within the ram somewhere…

thanks
