I used to left my iMac open all day running several VMs, no problem for my old iMac.
Currently jumped for a 2013 iMac, found after a day's running, the system simply left freezing, keybaord input or mouse moving simply doesn't respond. What is weired, the Wifi Sharing still in work.
I suspect the probelm is the VMware 5.0.2 so close it and test it for a day, without any problem working smoothly.
Currently working on trying weather it's some conflicts between other software with VMware, or maybe it's the graphic drive which conflicts.
Any other guy who has similar experience?
