Back to this saga.
I bought set of discs on eBay - thanks for the item number tip!
Setup a partion and did the install. Ran the updates, all is well.
Can’t use the same BT keyboard and mouse on both partitions (at least not easily). I really really like being wireless and don’t want to keep wired units there unless I absolutely have to. I will be accessing this via screen share for the most part so that is not an issue - but see below:
Startup disk on the SL side does not see the Sierra disk. I need to reboot with the option key.
Also, I think restarting is going to get old so I’m rethinking this.
I found an article about Fusion and SL but it was an older version. Does anyone know if this still works? Or if any other apps like that will let me run SL in virtual mode?
