    Any Way to Convert an MBR Flashdrive to GPT Without Erasing the Contents?

    Hi. I need a program called SpinRite to boot on the iMac (Late 2015 5K) but it won't boot because it's MBR. Is there a Terminal command or app that'll convert the USB flashdrive to GPT without erasing anything (it's bootable under a PC). Thank you in advance. God bless, Rev. 21:4
