Q: OS X Recovery Disk Assistant For El Capitan?


Apple provides a Recovery Disk Assistant that creates a Recovery System on an external hard drive.  That is supported for Lion and Mountain Lion and I have successfully used it on my Mountain Lion system.  It is here:


OS X: About Recovery Disk Assistant - Apple Support


Will this assistant work with El Capitan or is there something similar that will create an El Capitan Recovery System on an external disk?


Thanks.



iMac (21.5-inch Mid 2011), OS X El Capitan (10.11.2)

    El Capitan will install its own Recovery Partition. If you are overwriting an existing OS install the Recovery will be overwritten onto the previous

    Recovery version.

    Yes, El Capitan did overwrite the Mountain Lion Recovery System on the iMac internal hard disk. 

     

    But my external backup disk has a Mountain Lion Recovery System, and that has not been updated.  Is there a way to overwrite the Mountain Lion Recovery System on the external disk?  This was possible for Mountain Lion using the Recovery Disk Assistant, but I have not found anything similar for El Capitan.

     

    Thanks.

    I just tried it and it works perfectly.  It took a few minutes to create the Recovery Partition on the USB drive, then I booted holding 'option' and it showed the Macintosh HD, the Recovery HD on the internal HDD, then the Recovery HD on the USB drive.  Booted to it just fine and was able to see my Time Machine backup to restore from.
