has anyone managed to run fusion 2.x under Mac OS Lion? Since the update it says

Incompatibility with 64 bit kernel

This release of VMware Fusion does not work with 64-bit kernel of Mac OS X, you are currently running. To use VMware Fusion, you must restart your computer using the 32-bit kernel of Mac OS X again.

Any ideas :( ?

Upgrade to VMWare Fusion 3.1 which is compatible with Lion, with limited support from VMWare.

VMWare's knowledge base says

VMware Fusion 3.1.3 was designed for OS X 10.5 (Leopard) and OS X 10.6 (Snow Leopard). It is compatible with Mac OS X 10.7 (Lion), with the limitations listed below.

If you are running an older version of VMware Fusion, upgrade to VMware Fusion 3.1.3 before upgrading to Lion. Fusion 2.x is incompatible with Lion.

  • I would assume if you upgrade the OS all programs will fail unless you read otherwise. (You don't have to upgrade the OS)

  • Why should they fail? Just look at the windows world, do you know lots of programs that ran under Vista and will not run in Windows7?

  • Because OSs change the APIs that are called and how things work - After each upgrade there are always bugs - maybe not many but some and Sod's Law dictates one bug will be for a program you use.

VMware have said that Fusion 2.0 is incompatible with Lion.


Version 3 on the other hand, does offer Lion support.

Note also that the latest version of freeware Virtual Box is also Lion compatible.

  • Thanks for the link :-) … a highlight from the 22nd July 2011 edition, emphasis added by me: "VMware can provide best effort support if you choose to upgrade to Lion, but we cannot guarantee a resolution for all issues." — based on that line from VMWare you might edit your answer to clarify that VMWare support for virtualisation of Lion is currently limited.
