  1. Hi I am trying to install Niresh Maverick in virtualbox. While trying to start up the installation from the iso file (boot using -x -v), it got stuck at AGPM controller - unknown platform. I tried the suggested remedy at https://www.hackintosh.zone/forums/topic/408-agpm-controller-unknown-platform-mavericks/which is meant for successful installed but error at starting the installed OSX. My attempt failed because the iso file is mounted as read-only. All attempts to remount it as writable fail (naturally). I believe this post does not apply to the installation boot. My guess is that the installer is trying to boot up in AppleHDGraphic but failed? Is there any boot option that I can use to bypass this error? I would appreciate it if you could give me some pointers. Host Spec: Intel Core2Duo E7500. Windows 7 64bit. The Virtualbox can run Lion 10.7.2 fine.
