OC4VM 2.5.0
Important
All code relating to spoofing a real Mac has been removed and is no longer supported.
Upgrading to 2.5.0
Upgrading is as simple as copying the latest opencore.iso file for the CPU type to the VM folder. The ISO is found in the VMware folder of the distribution and you will need to pick the correct one from the AMD or Intel folders. No other files need to be copied from the templates

run Tahoe in a VM.
- Now uses an ISO file to boot using a hidden virtual USB CD drive
- AMD core patching no longer required use regular VMware CPU settings
- Support for Tahoe setting in VMX - only supported with new Fusion and Workstation 25H2
- Added guest tool shrinkdisk to shrink virtual disks from guest

OC4VM 2.0.1
Upgrading 2.0.0 to 2.0.1

There is one speedup that can be added to the VMX file of existing VMs to make mouse cursor movement better. If you want to apply this close down the VM and open the VMX file in a text editor and add this line:
usb.quirks.darwinVendor45 = "FALSE" # Disable Apple specific USB processing
Alternatively use the vmxtool provided to edit from the terminal:
tools/<windows/linux/macos>/vmxtool set <vmx file> usb.quirks.darwinVendor45="FALSE"
