Just a warning to any developers with access to the early releases of El Capitan... BIAB 2015 Mac from USB drive will not fully install if you choose to copy ALL files to your local drive by default.

The extra steps of it popping up Step 1 and Step 2 for RealDrums and RealTracks never appear.

You can just copy the Band-in-a-Box folder from the Applications folder on the external drive you receive and paste is over the one installed in your local machines Applications folder.

I confirmed with PGM support that this would work OK and it did.

Just wanted to give a heads up for any early adopters on El Cap.

Also as a side note for developers get prepared for some limitations in El Cap since the implementation of System Integrity Protection (SIP). Files you could manipulate in /usr are no longer possible. I foudn that out when trying to rename /usr/bin/git so I could use non-Apple git. Just an extra FYI for ya!
