Want to try? Make sure you’re running OS 10.5.7, then install LP9 and then it should be working…..
Glad I tried this first, I was almost fooled in buying a new Mac Pro. My G5 Quad is still a very capable machine, so I hope it will run at least another year.

Hi, Ref Logic Pro 9 on G5, How did you get over the install part when it tells you that it will only work as intel
Can’t remember coming across that message. Which version installation dvd do you use?
Logis pro 9 2.1
The last version working on a G5 is 9.1.6…..
