What software do professional graphic designers work with?

And what are the requirements for matching notebooks?

Photoshop and most use Apple notebooks.

Notebook less, but it should be synonymous.
Mostly you use Adobe products on Potent Workstations.

According to what is called professional.

there are people who sell… Eisse but because they earn their money with it they are profi by definition.

I think so; if someone is pro, he can do it with any tool he has (software) because it is much more a question of basics.

they are only more efficient with their usual tools. That will be mostly adobe.
