@JP_7 https://forum.parallels.com/threads/tools-patch-procedure.351669/ These are the detailed instructions kindly provided by Mark Fine with full disclaimers. This was never intended for an end-user to DIY. It is literally editing your kernel. The good news is you can take a Snapshot beforehand and do this as many times as it takes. I was successful but it took me several hours because this was the 1st time I ever attempted such a thing. Granted I could do it much faster next time- but there is no way I could guide someone via text in a forum. Best of luck.
