is this tool safe on macpro 1,1 with el captain 10.11.6 install?

Yes, it is, it will work on all Mac computers and Hacks. But I suggest you don't use it if you don't know what it does.

Hi

 

It would be practical, if nvram allowed to choose the HDD that we want to do his job 

I couldn't get it to work. sudo command needs to be executed with administrative privileges and running it on another os didn't work.
