    Thanks for your input. And thanks for the reply from mrkramer with that link. I really am surprised at how easy the install went and how great it runs. I put my other drives back in and have been switching back and forth between El Capitan and High Sierra and the latter seems to run faster, but it's probably just because El Cap has had years of use.
    Thanks again to all
    Glad it's working for you. I hadn't ever had the need to actually try those instructions, but I had heard from people who had done it so I thought it might benefit you.

    Just a small caution on SIP. In past updates, Apple has turned SIP back on if it was found to be off in the update process. In your case, if SIP must be off for the OS to even run (I don't know that, just taking your statement at face value.) then if there is an update to HS and you install it, you might end up with a system that won't run. I would recommend making a bootable clone of what you have now, just in case. That way, if the update does kill the system you can restore the clone by booting from it and cloning back.

    I hadn't done any reading of SIP, but having found this article about it, you should be really careful with that layer of protection.

    Just to reinforce Jake's cautionary comment, but I don't know if Apple changed anything with its latest versions. But I suspect they may have done even more to re-enable SIP and keep it enabled. Apple really like their security stuff working.

    I'm not going to worry too much about it since you turn off SIP before the os starts. If for some reason it enables itself, I should be able to boot into recovery and shut it back off.

    That sounds reasonable and should work.

    And once it's disabled, SIP should stay disabled, even between restarts or shutdowns I would think.

    Once you turn off SIP, it will not reenable itself arbitrarily. It will, however, reenable if you upgrade your version of macOS. For example upgrading from 10.13.4 to 10.13.5 will turn SIP back on.

    There are certain apps which mess with system icons or the dock that require SIP to be first turned off before any changes can be made. Also the "Paragon Disk Manager" software will not work unless SIP is turned off first. The Paragon software can move or change partitions and has been upgraded to work with APFS. Always make a backup before you mess with SIP or an app that makes changes to system stuff.
