Hi Guys, I'm running a 32bit image (Pharo5) on OSX Mojave on Parallels but unfortunately it crashes. The same image is working on my old mac with Mojave so I'm wondering what the issue is. Reading the dump file it seems a display problem but I'm not a vm expert so here is the dmp, I'm seeking help from you, thanks Davide Segmentation fault Tue Jun 1 19:03:55 2021 VM: 201707012338
