Here is the source for a kernel extension that can test whether VT-x is present on the processor and whether or not it can be used: http://das.doit.wisc.edu/misc/vtx-check.zip To use: - Unpack the archive - Go into the vtx-check directory and type "make" (requires that the Developer Tools have been installed) - Load the kext with "sudo kextload MacOS/vtxcheck.kext" - Look at "dmesg" for details; you should see a message indicating whether or not VT-x can be used on your system It would be good if people could try this with their Mac mini and report back WITH YOUR SERIAL NUMBER: Confirmed working: - iMac (Core Duo) (all models) - MacBook Pro (Core Duo) (all models) - Mac mini (Core Duo) (firmware: MM11.0055.B02, serial: YM60935SU39) - Mac mini (Core Duo) (firmware: MM11.0055.B02, serial: YM608JEJxxx) - Mac mini (Core Duo) (firmware: MM11.004B.B00, serial: YM608RPVxxx) - Mac mini (Core Duo) (firmware: MM11.0055.B02, serial: YM610237U39) Confirmed NOT working: - Mac mini (Core Duo) (firmware: MM11.004B.B00, serial: YM608QS0U36) - Mac mini (Core Duo) (firmware: MM11.0055.B02, serial: YM608QS0U36) - Mac mini (Core Duo) (firmware: MM11.004B.B00, serial: YM6092JZVJN) - Mac mini (Core Duo) (firmware: MM11.0055.B02, serial: YM6092JZVJN) - Mac mini (Core Duo) (firmware: MM11.004B.B00, serial: YM610237U39) - Mac mini (Core Duo) (firmware: MM11.0055.B02, serial: YM6087PJU36) - Mac mini (Core Duo) (firmware: MM11.0055.B02, serial: YM608R0VU36) To be tested: - Mac mini (Core Duo) before Mac mini (early 2006) Firmware Update 1.0 (firmware: MM11.004B.B00) - Mac mini (Core Duo) after Mac mini (early 2006) Firmware Update 1.0 (firmware MM11.0055.B02) - Mac mini (Core Solo) before Mac mini (early 2006) Firmware Update 1.0 (firmware MM11.004B.B00) - Mac mini (Core Solo) after Mac mini (early 2006) Firmware Update 1.0 (firmware MM11.0055.B02) Thanks! UPDATE: It's looking like it's not as clear cut as models here, since we have at least one person with a Mac mini Core Duo that DOES have VT enabled. I'm guessing it was an issue that got caught, and newer Core Duo Mac minis have VT enabled. __________________ Dave Schroeder University of Wisconsin - Madison das@doit.wisc.edu http://das.doit.wisc.edu |
