El Capitan Boot From Usb

Apr 04, 2021 An El Capitan.DMG is downloadable directly from the Apple Support page, which provides instructions on how to make a bootable volume, with a major caveat On a Mac that is compatible with El Capitan, open the disk image and run the installer within, named InstallMacOSX.pkg. 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. Finally, I could boot up the Mac while holding 'option/alt' and my USB drive appeared as a bootable device! 17 minutes later I can startup OSX! I may go ahead and re-download the installer and create a new bootable USB using 'createinstallmedia', just in case there was a problem with the image I used, but at least now I can boot up the computer!
