Hey all

When trying to set read write permissions or even adding administrators I get an error

"the operation canot be completed because you do not have the necessary permission"

I have a Mac Mini M4 Pro OS 15.2 and am logged into my Administrator User and I have my home folder on an external drive

I am trying to run Black Magic Design HD Benchmark test on my Macintosh HD I select it as target drive and it tells me I dont have permission so I click on my Macintosh HD and select Get info I goto Sharing and Permissions I unlock it and I try to change read only to Read Write bit I get that error so I try to add administrators and I get this error Need Help
