Crabhunter Posted April 16, 2018 Share Posted April 16, 2018 I'm very confused about the MBR method of installing High Sierra 10.13.xx First off, the two partitions the guide talks of, are they on the USB installer or the hard drive I intend installing to.

Crabhunter Posted April 17, 2018 Author Share Posted April 17, 2018 That's what I have but just don't know what to do with it. In the past it's just been a case of replacing two files on the installer but I don't know where to start with this new method. Mike Link to comment Share on other sites More sharing options...
PippoX0 Posted May 25, 2018 Share Posted May 25, 2018 (edited) My easy way to resolve MBR install is to install first on external USB disk with a GUID partition and HFs+ and then copy with Carbon copy cloner on Internal HDisk MBR partition. sent from my iPhone Edited May 25, 2018 by PippoX0 1 Link to comment Share on other sites More sharing options...
