The problem is that I am using Lion 10.7.5 on my MacBook Pro, Late 2011. I want to use iCloud so I bought an Apple ID. I also bought a new and untested Lion installation disk and downloaded the Lion 10.7.5 installed disk. I also bought a new and untested El Capitan 10.11.6 system boot disk. I also bought and untested Seagate back up and desk 5 TB external power hard disk.
I just bought a new MacBook Pro (13-inch, Late 2011) from Late 2012 and would like to use it to replace my MacBook Pro, Late 2011. I also bought an iMac Quad-Core Intel i7 3.3 GHz with 8 GB RAM and a 1TB Hard Drive.
When I boot from the El Capitan 10.11.6 system boot disk on my MacBook Pro, Late 2011, I get an error message that the hard disk is not recognized. I would like to know how to install Lion on my MacBook Pro, Late 2011. I would also like to use the same El Capitan 10.11.
I hope someone else can help me here. I've spent more than 2 hours reading and trying to find an answer to this. I'm giving up and will just work with the local files on the MacBook Pro, the local files on the iMac and the iCloud files. I'd like to have these all in sync with each other because I have years of research and document work on each of these systems and they are not being treated well as it is. I've also used Google Drive and Dropbox and they work perfectly for me.
Anyway, I would appreciate it if you would tell me how to fix this? I'd like to get both the My Passport 2 TB disk and the Passport 0748 2 TB disk and the My Book 1234 2 TB disk all plugged into the ElCapitan 10.11.6 bootable disk.I really don't want to use the My Book 1234 2 TB disk to be the main source of my documents. I also don't want to have to plug-in a DVD drive into the MacBook Pro. I really would prefer to have all my files on the internet, not on a DVD disk on a portable computer.
