I originally wrote this 'How To' in the following topic 'Workstation 8/9, Player 4/5 and Fusion 4/5 Mac OS X Unlocker' started by Donk, see link below, since there are now some 500+ replies in the topic, I thought it was time to extract the post and start a new topic. As with OS X Mountain Lion (10.8) several methods are available to install Mavericks (OS X 10.9), Yosemite (OS X 10.10) or the recently released El Capitan (OS X 10.11) as a free upgrade, thanks Apple! Mavericks (OS X 10.9), Yosemite (OS X 10.10) or El Capitan (OS X 10.11) can be installed as a FREE UPGRADE on an existing OS X Snow Leopard (10.6.8) or later virtual machine, but make sure your virtual machine to be upgraded meets the minimum specification for Mavericks, Yosemite or El Capitan (2 Processors and 2 GB RAM), by default OS X Snow Leopard installs with 1 Processor and 1 GB RAM, so edit the virtual machine settings before attempting an in-place upgrade.

I would also advise making sure your to be upgraded OS X virtual machine is fully patched, and take a snapshot before you start. To install Mavericks (OS X 10.9), Yosemite (OS X 10.10) or El Capitan (OS X 10.11) as a fresh install is more complicated as extracting the DMG file as detailed in the first post of this topic does NOT create a bootable image. In order to create a bootable DMG that works in both Workstation 10/11/12, Player 6/7/8 and ESXi 5.5/6.0 requires an Apple script to create the bootable DMG from the 'Install OS X Mavericks', 'Install OS X Yosemite' or 'Install OS X El Capitan' app downloaded from the Mac App Store.

The release of Fusion 7 added support for OS X 10.10 (Yosemite) but required VMware to make a lot of changes to provide acceptable levels of performance for Yosemite as a virtual machine, and even with the changes performance is reduced compared to Mavericks even using the latest VMware Tools from Fusion 8. JasF has written an app called BeamOff which resolves the performance issues of Yosemite when running as a VMware virtual machine, see link below: Please note currently BeamOff does not support El Capitan, although some performance increases have been noted using El Capitan with the latest VMware Tools from Fusion 8 compared to Yosemite.

HPReg (VMware employee) has confirmed VMware will include the BeamOff workaround in to the VMware Tools for a future release of Fusion. Native support for Mavericks (OS X 10.9) is included in VMware Fusion 6 and ESXi 5.5 running on Apple hardware, and once unlocked Workstation 10, Player 6 and ESXi 5.5 but require hardware compatibility set to version 10. Native support for Yosemite (OS X 10.10) is included in VMware Fusion 7 and ESXi 6 running on Apple hardware, and once unlocked Workstation 11 and Player 7 but require hardware compatibility set to version 11. Native support for El Capitan (OS X 10.11) is included in VMware Fusion 8 and ESXi 6 running on Apple hardware, and once unlocked Workstation 12 and Player 8 but require hardware compatibility set to version 11 or 12.
