MP All Models Installing El Capitan on non Mac Pro

[howardc64]

As far as I know, after installing retail version of El Capitan on an HDD, the HDD can be moved to any other Mac that can accept the HDD and El Capitan and will boot perfectly. This has been the case since like 10.6

Anyone know if this is true for Mac Pro also? Assuming a model that works with El Capitan of course.

I don't own a Mac Pro but plan to make an HDD (with my 2013 Macbook Air i5 or 2009 iMac C2D) snd send it for a friend to use in a Mac Pro.

Just make sure the kernel and both boot.efi files are MP1/2,1 compatible after you do all the software updates.

I have Mac Pro 2,1. Trying to upgrade to El Capitan from OSX Lion 10.7.5 using Pikify App. To do so, El Capitan must be in the Apps folder. Downloaded El Capitan.dmg directly from Apple website (6.5GB). Ran it and now have the El Capitan.mpkg file. However, the installer won't allow El Capitan to be installed on my 2,1. The installer simply provides the error message and only allows you to close the window. Thus, I can't access the El Capitan.exe file.
I have tried to access it through Suspicious Package and Unarchiver software to no avail.

Does anyone know how to override this? How can I get the .exe file into the Applications folder so that I can use the Pikify App? Can anyone upload the El Capitan.exe installer file here? The bottom line is that I have the El Capitan.mpkg file but can't do anything with it.
