Follow these steps to create a bootable USB installer of El Capitan in Terminal. Connect the USB flash drive to your Mac. Give the flash drive an appropriate name. You can do this by double-clicking the device's name on the desktop and then typing a new name.
Created a bootable USB with El Capitan installer
booted from it, erased my MBP (mid 2009), clean install from USB installer
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
Jesus Vigo shows you the easiest possible way to create a bootable USB installer for OS X El Capitan. At this year's WWDC, Apple announced the next iteration of OS X, version 10.11. Just click on the setup file and with some click, the installation will finish. After that, Launch TransMac when TransMac is launched you will see the list of Flash drives or local disk. Then Right-click on that flash you want to create bootable USB for Mac OS El Capitan then select Restore with Disk Image. Restore with the Disk image.
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.
Make Bootable Windows Usb Mac
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
with a non clean install again.
Any help, suggestions.....?
