Leopard and Lion on Separate drives on a Mac Pro

Postby forumuser663843 » Thu Jan 24, 2013 10:35 pm

Hi. is it possible to have two drives, one with Leopard and the other with Lion on Mac Pro and be able to switch between the two? The reason I need to do this is that Im upgrading cubase 4 to 7,but still need to be able to use cusebase 4 for some older projects.

As Chris says, yes it is.

Using disk utility you just wipe and install each OS on each HD, you then normally hold 'alt' on startup and it simply lets you choose the OS boot.

You might be better off partitioning one of the HD's, doing a similar dual boot process and using the other HD for storage etc. - things like audio files or sample libraries if you use them. This method can help improve performance although with a lot of current comps and HDs the difference may negligible.

There's loads of info via google on 'setting up dual boot systems'.

I do this with Leopard (Cubase4) and Snow Leopard (Logic). I just have to remember to hold the Alt (*) key down when it's booting and you get to select which drive to boot from.

(*) or the apple key ... I can never remember which it is an sometimes it takes couple of goes. But I'm getting old and flaky

For what it's worth:

It's not the apple key aka "CMD" (which no longer has an apple on it, but does have the clover leaf thing).

It is indeed the "ALT" key, which back in the day was called "Option". So I used to remember: I want an option of what drive to boot from.

Better still, I use rEFit which allows you to select which disk you want to boot from without any of that option key stuff. Find it here.... refit

Pretty sure you can open C4 projects in C7 too, just not the other way around.
