+--- Thread: Should I make a bootable USB High Sierra Drive to install new OS X? (/showthread.php?tid=218112)
Should I make a bootable USB High Sierra Drive to install new OS X? - Microman - 06-30-2018
I am going to put that new SSD in my MacBook tomorrow, should I just do all the work, by leaving the existing drive in the computer, or boot up from a USB with the Sierra or High Sierra on it, and go to Disk Utilities and format, and then install.
HS OR S
Internally or Externally?
Will the install then have the Boot partition for Utilities?

Sierra. I usually install to the drive externally and test it first. Make a USB thumb drive installer for future reference.
"Will the install then have the Boot partition for Utilities?"
This will require some extra steps. I'll find you instructions and post them tomorrow, or just Google it.

Created boot disk for HS, and it boots to UTILites. But the new 500 Gig Samsun Evo 860 doesn't show up as a choice to install Mac OS X HS or does it show up in Utilities. I will research why. It is hooked up externally thru one of those Seagate external drives that the drive can be plugged and unplugged.

Your SSD probably didn't come formatted for Mac.

Problem was, that when I hooked the new external SSD Samsung up to the SEAGATE plug and play like cable, it reads it as a SEAGATE device on UTIL. So thats why I thought it was not seeing it. I have now installed HS on the external SSD, and will look into what is needed to get the Emergency Volume on there, and what is TRIM, is that something I should turn on? I remember hearing/reading about it, on one of the places I researched.
Just booted with the new SSD chosen as the startup disk, and had the OPTION key down, and there appears to be a recovery partition.... Yea...
