• Make sure the El Capitan installer (or at least a copy of it), called Install OS X El Capitan.app, is in its default location in your main Applications folder (/Applications). Select the text of.
• Mac Os X El Capitan Bootable Usb Download – Pete Batard created Rufus for our quickly changing age exactly where DVDs are becoming a lesser amount of important, and USBs are taking over. Several computers no longer possess DVD drives for that reason holding onto installation software needs to be held in a distinct format.

You’ve got two problems. First you can only obtain El Capitan from the Mac App Store, and that requires using a Mac running Snow Leopard or later. The link is here: Connecting to the Mac App Store Second problem is creating a bootable USB drive. As usual, Apple no longer supply a bootable USB Flash Drive with latest OS X releases - including the new OS X 10.11 El Capitan. Using this tutorial you will.

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

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

with a non clean install again.

Any help, suggestions.....?

Cheers

Why do you need to download El Capitan through Terminal.

El Capitan is freely available from this link.

Here are the instructions.

Go to Section 4 and click on Download OS X El Capitan.

This downloads InstallMacOSX.dmg to your Downloads folder.

The next section can only be done on a mac that is capable of running El Capitan,

a mac that came preinstalled with an OS later than El Capitan will refuse to do the next bit.

When downloaded open to InstallMacOSX.pkg, double-click on

that and an installation window will open, this does not install El Capitan

but converts the InstallMacOSX.pkg to the Install OS X El Capitan.app which

you will find in your Applications folder, it should be 6.2GBs in size.

Create Bootable Usb Os X

(If the installation window asks which disk you want to install to, you must pick

the disk that you are booted to at the time. Not any internal or external disk that

you want to eventually install El Capitan on, that is for later.)

To start the installation of El Capitan double click on the Install OS X El Capitan.app.

The copy of the install app self deletes after installing El Capitan, so make sure you keep a copy of the InstallMacOSX.dmg

Bootable Os X Mavericks Download

if you need it in future, or you could just make a copy of the Install OS X El Capitan.app prior to installing and moving it to

an external drive for safe keeping. It is also possible to create a bootable USB installer disk using the Install OS X El Capitan.app

in the Applications folder and the createinstallmedia command in the Terminal app.
