Can’t find systemversion.plist when doing bless bootefi

Hey, I’m using OPLC since a few time, and at the start of this week, I had my Mac having few issues (really slow, strange dock, hdcp errors with the internal screen, …), so I decided to update the root patches I ended up with my Mac stuck in the startup screen, so I’ve tried the troubleshooting advices on the website, and it worked. But, after updating OCLP another time, I faced the same issues So I’ve tried another time, and ended up again being stuck on the startup screen The problem is that now, when I try to do that code line “””Bless —mount “/Volumes/MacBookPro” —bootefi —last-sealed-snapshot””” I have this message error (in the picture above)

If anybody is able to help, that would be really appreciated!
