Problem with Macbook Pro M4

Hello,

i am new to cnc. I have a twotrees TTC450 Pro machine, i am doing CAM work in Fusion and i use the free version of easel to send the nc file to the machine.

I have an old Macbook pro with an Intel i9 chip and the newest OSX. I am using Chrome browser and i installed the latest easel driver. Everything works fine.

Now my problem:

I have a new Macbook pro m4, latest osx, chrome browser and the latest easel driver.

I can control the machine in the carve menu, set xy zero, use the probe to set z zero, turn on the spindle, etc., everything seems to be normal,

but when i press start carve the machine doesn´t move. It stays in xyz zero.

On both settings i tested it all with the same nc file, generated in fusion with the easel Postprocessor.

I also tested Safari browser, but there the carve button stays blue and i got no control over the machine.

The machines also cames with grbl candle for mac. I installed this on the new mac, made a new path with the grbl postprocessor and it works.

But i want to use easel, i like it, its userfriendly and good for beginners like me.

Hope someone has an idea

Stepho
