I have my old MacBook Pro that has 10.6.4 Snow Leopard just if I want to mess around + to run old software, but now I also need it to host a “server” (if you could call it that) - so I need 10.13 High Sierra on it.
Problem is, I don’t want to go through those 8 hours of installing 10.6 on this computer again + I may need to use that older software again, so I want to have one partition be 10.6 and the other be 10.13. Would it be possible even with 10.13 using the APFS file format?
I know absolutely nothing about software - so sorry if this sounds like a rather dumb question.
