Thank you for your time. Here is my problem:
Start into Mac OS X El Capitan internet recovery mode and temporarily disable System Integrity Protection (SIP) to use (X11 functions of) Wineskin.
I've got two systems on my 2011 MacBook Pro as partitions:
Mac OS X Snow Leopard 10.6.8; this is the default startup disk and the "factory set" OS (actually Lion) of the computer.
Mac OS X El Capitan 10.11.6; apparently without a recovery partition...
I access this OS via the startup manager ([Opt key] at Mac chime).
To boot into (internet) recovery mode I normally would press [(Opt +) Cmd + R] at the Mac chime and then disable SIP from the Terminal (csrutil).
As of the system configuration above, if I do this, it starts into internet recovery mode of Snow Leopard, where I cannot change the status of SIP because the csrutil command does not exist yet in this OS, of course.
- But my intention is to start into internet recovery mode of El Capitan, not Snow Leopard.
How can I achieve this with this configuration?
D) What I've tried so far
Enter the startup manager ([Opt] at chime), choose El Capitan and then hit [Cmd + R].
= Does not start any recovery mode.
Change the default start up disk to El Capitan and hit [(Opt +) Cmd + R] at the chime.
= Starts into Snow Leopard recovery mode...
Create a recovery partition this way.
= Does not work; Recovery Partition Creator 4.0.4 seems broken.
E) Additional Questions
Those don't have to be answered necessarily, but if you do: Many thanks!
I'd like to avoid reinstalling El Capitan to create a recovery partition since I believe in a simpler solution. But as a last straw, I'd do that of course. Would this be advisable?
If I installed El Capitan on an external drive, could I disable SIP from there (or its recovery partition) or would I run into the same problem?
Could I disable SIP via Firewire Disk Mode; that is from another computer (in this case OS X Sierra)?
Could I start into El Capitan recovery mode from verbose mode?
I'm probably mistaken, but does the EFI partitions which I see in terminal (diskutil list) have anything to do with the recovery mode? If yes, could I start into that (from verbose)?
Out of curiosity: Why didn't create El Capitan no recovery partition in the first place? (There is none when I do "diskutil list" in Terminal, only a "Boot OS X", but that's probably something about Snow Leopard...)
Thank you very much in advance!
