iMac 27 does not boot from USB
Hi all,
I had to change the hard disk of my iMac 27 (late 2015) because it was broken and now I cannot reinstall the macOS.
I do not have any other iMac and I tried to create the USB from a Windows computer using TransMAC app. I tried with Sierra and Capitan macOS dmg files.
When I restart the iMac holding OPTION key, I cannot see any bootable disk.
Any idea how I could create a bootable USB from Windows?
Thanks in advance for the help.
Regards,
Rafa
