Hello @carlos-mg89, please copy your system information from steam (Steam -> Help -> System Information) and put it in a gist, then include a link to the gist in this issue report.
I've just realized that the sound isn't working. I didn't notice, cause I didn't have the speakers with volume.
Nothing extracted yet.
Ubuntu 18.04
8GB RAM
Macbook Air i5-4250U
Intel 5000
Works perfectly!
