Cant format disk with OS Sierra Disk
Hi all, when trying to boot from my usb os x sierra drive i get the forbidden icon. This is the latest release and is not working. I cant find why this is not compatible. I also try with El Capitan. This is a Macbook Pro Retina 13" 2017 A1706 EMC 3163
Es esta una buena pregunta?

How are you creating the USB OS X Sierra drive?

Are you booting your computer and then running the installer app? Have you created a bootable USB volume (e.g., via createinstallmedia)?

Im creating the usb with DiskMaker X, that makes the thing bootable

@sbotalla , use Sierra's own terminal command "createinstallmedia" to make a proper bootable USB. You need a working Mac with Sierra's installer app on it. See this article. https://lifehacker.com/how-to-make-a-boo...
