But I cannot select USB 3.0 in the case of Mac OS X 10.6.8 Server, as said. I have seen that I can select USB 3.0 with Windows XP, Windows 10 and Ubuntu 16 ( all of them showed as USB 2.0 instead of USB 3.0 after the VMware Fusion 8.5 update!!!). USB 3.0 cannot be used unless the virtual hardware version is upgraded. But I cannot select USB 3.0, since it is gray dimmed. In a popup menu in which I can also select USB 1.1. Virtual Machine > Settings > USB and Bluetooth > Advanced USB options Once I turn off the virtual machine (Mac OS X 10.6.8 Server) I have fixed issue 1 above reinstalling iTunes for Mac OS X 10.6.8 (which reinstalls AppleUSBEthernetHost.kext).

I must unplug the USB disk or 'Virtual Machine > Restart' (or Shut Down) to get out of it. If then I click OK to continue, Mac OS X 10.6.8 Server is frozen. This might result in undefined behavior for this device. The device '.' was unable to connect to its ideal host controller.Īn attempt will be made to connect this device to the best available host controller. Also, when I plug an external USB pendrive, I get: Please try reinstalling it, or contact the product’s vendor for an update.Ģ. The system extension “/System/Library/Extensions/AppleUSBEthernetHost.kext” was installed improperly and cannot be used. Repairing permissions with Apple Disk Utility does not fix it either. I have reinstalled and even uninstalled and reinstalled 'Virtual Machine > Reinstall VMware Tools' to no avail. The issue arises only when mounting in Mac OS X 10.6.8 Server (which is a virtual machine of VMware Fusion). No problem mounting USB devices in Mac OS X 10.11.6. The issue arose after updating VMware Fusion from previous version. Rosetta is needed to run some Mac applications, and Snow Leopard is the last Mac OS X supporting Rosetta. Cannot mount USB 3.0 external disk on Mac OS X 10.6.8 Server (Snow Leopard) 64-bit on VMware Fusion 8.5.0 (4352717) on Mac OS X 10.11.6 (15G1004) El Capitan.
