My main Mac, that I use for work, is full of all sorts of programs and is struggling a bit. I have another MacBook - not a recent one - but probably about the same age as my main one.

If I take the spare one and try to optimise for BIAB use, are there any tips - maybe an existing thread?

I'm happy to delete other programs and data. I am using an external drive ultra pak, BIAB product that I got new about 18 months back, and am just looking to play back backing tracks for practice.

Thanks for any ideas folks!
