This happens when running VMware Fusion Profesional 12.2.1 (18811640) on Big Sur 11.6.1 (20G224), Intel MacBook Pro (Retina, 15-inch, Mid 2014), Windows 10 Pro 21H1. Hi, I am having the same/similar issue: total crush of the VMware virtual machine many times a day, totally switch off without any previous advice and forcing to a restart of Windows. Has anyone else experienced this crash pattern, or have any insight into its cause or resolution? I suspect that something that changed in Big Sur 11.2.3 conflicts with kernel extensions from Fusion, since the crash problem began after 11.2.3 was installed.Īpple Support disclaims any responsibility for behavior related to a 3rd party app, even though an OS crash results. With a Fusion VM running, both systems crash within 24 hours.Ī Fusion VM running under Fusion 12.1.1 and Big Sur 11.2.3 now with certainty crash two different Macs. With Fusion not running, neither machine crashes. Over a period of two weeks i experienced more than two dozen of these kernel panic crashes.Īfter strenuous troubleshooting and process of elimination, I discovered that Fusion operating a VM has been the sole reason for the crashes. The crashes occurred both in the middle of the night when there was no console activity, as well as right in the middle of an active console session. Shortly after those MacOS upgrades, both Mac began to crash with kernel panics (unrecoverable). They both continued to operate their Windows VMs successfully.Ībout a month go I applied the Big Sur upgrade 11.2.3 to both Macs. I upgraded both Macs to Big Sur 11.1 and eventually Fusion to 12.1.1. They were both running Catalina and Fusion 12, each successfully supporting a Windows 10圆4 VM. gfxCardStatus (integrated only mode) is better in this respect so I use both and now I can say that the machine is very stable and reliable after all.I have a MacBook Pro 16 (2019) and a Mac Mini (2018). After about a week of gpu-switch testing, however, I have to conclude that this solution has its drawbacks too: it works fine after shutdown (including abnormal or forced one), sleep, hibernation, but it does not prevent mbp from switching to dgpu on running graphic demanding apps such as googlemaps in browser. ![]() This saved me from frequent overheat shutdowns under blanket just to load the os (after overheat shutdown the system forcibly uses igpu but this state changes back after couple of boots so it becomes necessary to overheat again). The application runs from terminal, uses the same code as gfxCardStatus but writes the setting into NVRAM(PRAM) so machine remains switched to internal GPU on next boot(s)/wake(s). Please note that only source code is there so Xcode is requred to compile the binary. It seems that I have found more reliable or permanent software solution allowing to disable discrete GPU and use mbp (mine is Mbp 8.3 early 2011, Yosemite) with broken discrete GPU (failing to boot) than gfxCardStatus 1.8-2.2.1, namely.
