I have two new 2017 MacBooks that came with High Sierra preinstalled. Neither one has a recovery partition. Therefore, when I hold Command R at boot, the only option is Internet Recovery and once it has loaded, the command csrutil disable in terminal returns an error that the “command not found”. Thus, I cannot disable SIP and install TotalFinder. Which is a shame since I’ve been using it for years and love it.
This is alarming ! I intend to upgrade in the next year or two.
You may want to research ‘Carbon Copy Cloner’ , it has a built in utility to create a Recovery Partition and takes care of all the technical stuff. Suggest you get in touch with them to confirm it meets your needs.
