Hello Everyone, Well, it's that time of year, again.
I hope you find the following information useful. Good Luck, Mark How to make a bootable OS X El Capitan USB key These are instructions on how to make a bootable OS X El Capitan USB key. 1. Download OS X El Capitan 10.11 from the Mac App Store. When the download has finished, make sure that you quit the installer rather than actually going through the process of upgrading over the top of your existing OS X installation. Make sure that the installer that downloads the El Capitan file is located in the /Applications folder under the name 'Install OS X El Capitan.app'. 2. Connect a 8GB or larger USB key to your computer. We're going to need to format the USB flash drive to get it into a state where it can accept the payload for the installation of El Capitan. 3. Launch the Disk Utility application. 4. Select the USB flash drive in the left sidebar. 5. Click the Partition tab. 6. Set the Partition Layout to 1 Partition, set the Name to Untitled, and set the Format to Mac OS Extended (Journaled). 7. Click the Options button then choose GUID Partition Table from the popup window then click the OK button. 8. Next click the Apply button to save your changes. When asked to confirm click the Partition button. 9. Launch Terminal from the Applications:Utilities folder. 10. Make sure your empty USB key is still inserted. Additionally, make sure you do not have any other volumes named Untitled except for the one we just created in Step eight. Now, execute the following command in the Terminal window to create your OS X El Capitan Install key: sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ El\ Capitan.app --nointeraction 11.
