Firstly thank you all for advise and so quickly.
I have been producing tracks since 1993 starting on Amiga 500 with Octamed software with various hardware (roland r9 - Akai 3000s- Yamaha qy70 - )
In 2002 I got my first PC Hp pav mentioned after trying Qbass Reason I got a copy of Logic pro platinum 5.5.0 and bingo 300 plus tracks made.
Then Apple ruined it with 2 mbps with serious graphics issues famous 2 models 2007 and 2011 still trying to find a fix for 2011.
Using logic 8, 9 10 was great and spec wise not matter tho last version of logic x on macbook pro 2011 high sierra i5 8gb was perfect.
Updates are not my thing solid state offline
So mini mac looks good although my hakintosh build wont go online its set up to be as my last mbp 2011 was just 16gb ram instead.
