This 32Gb USB flash drive contains a full bootable install disk for macOS 10.11 (El Capitan). It can be used to rescue a dead hard drive, or SSD, or if your Apple Mac or MacBook Pro has stopped starting up. 

Unlike other similar eBay listings, this drive provides the FULL INSTALL version of the operating system, and not just upgrades. This means it can be installed on a completely blank or freshly formatted hard drive/ SSD as well as upgrading an existing operating system. 

To use this drive, ensure your Mac is shut down and then press the power button to start it up, holding down the Option key until you see the Apple logo appear on the screen, and then follow the instructions on screen. The installation process will take some time, and may need to reboot several times. This is normal, so please be patient while it installs.

Please note -- if performing a fresh install of macOS El Capitan, all previous data and settings on the hard drive will be lost, so ensure you have your files backed up.

Further instructions can be provided, if requested. USB drive colours may vary. If you have any difficulty with the installation process, send me a message on here and I can take you through it step by step if necessary.

IMPORTANT: El Capitan takes a notoriously long time to install. The process can take up to 12 hours (depending on your hardware). If you require a shorter installation time, you may want to choose Sierra or High Sierra instead.
