Linked below is the most complete guide I have found on the topic of creating a bootable copy of the Mac OS installer on a USB flash drive. The MacWorld guide and even Apple’s own support document, which other answers to this topic have linked to. If you wanna create bootable USB flash drive for Mac OS X El Capitan on Windows PC. You need a TransMac Software. That’s not a problem if you use a computer that supports legacy or UEFI. Just you need TransMac and El Capitan dmg file. Siddharth choubisa September 20, 2016 at.

Created a bootable USB with El Capitan installer

El Capitan Direct Download

Mac El Capitan Usb

booted from it, erased my MBP (mid 2009), clean install from USB installer

RTL8111 kexts don't seem to inject (El Capitan Internet Recovery USB using gibMacOS) HELP. I'm hoping to get El Cap up and running on an old Nehalem system (Xeon X3470, but GTX 280 which I understand is limited to 10.11) and can boot into the internet recovery just fine with no issues following the vanilla Internet Recovery guide.

decided to use migration assistant, most apps not working plus all the clutter from pre clean install

decided to do another clean install but MBP won't boot from USB and uses the recovery version instead.

tried to get Maverick back and basically ended up with a non-working MBP that went into a boot loop

did a reinstall from MAS, ended up DLing the entire Installer again, went to bed and in the morning and 'working'

MBP again, plus all the clutter and non working apps.

Made a new bootable USB key using terminal and yes it finished and yes it said bootable at the end as well as in Disk Utilities.

However when trying to boot from USB, start+Option, or start+cmd+r still no sign of the USB stick, which i guess would leave me

El Capitan Recovery Usb Installer

with a non clean install again.

Any help, suggestions.....?

Cheers
