About to buy a macbook for my studio sessions. does anybody on here use ecuflash on macbooks software OSX and does it run basically the same as pc?

 

It is the same but the driver for the Tactrix cable is generic and does not work that well.
You can open, edit and save your ROM but you can not be sure to get well connected with the car.
Most of Apple users install Bootcamp or Parallels to run PC version works on Mac!
Cheers
