0.9.3 (??/??/2015):
-------------------
+- Added new "spoof_osx_version" token, which takes an OS X version number
+ (such as "10.9") as an option. This feature, when enabled, causes rEFInd
+ to tell a Mac's firmware that the specified version of OS X is being
+ launched. This option is usually unnecessary, but it can help properly
+ initialize some hardware -- particularly secondary video devices. OTOH,
+ on some Macs it can cause hardware (notably keyboards and mice) to become
+ unresponsive, so you should not use this option unnecessarily.
+
- Worked around an EFI bug that affected my 32-bit Mac Mini: That system
seems to have a broken EFI, or possibly a buggy CPU, that causes some
(but not all) conversions from floating-point to integer numbers to hang
#
#enable_and_lock_vmx false
+# Tell a Mac's EFI that OS X is about to be launched, even when it's not.
+# This option causes some Macs to initialize their hardware differently than
+# when a third-party OS is launched normally. In some cases (particularly on
+# Macs with multiple video cards), using this option can cause hardware to
+# work that would not otherwise work. On the other hand, using this option
+# when it is not necessary can cause hardware (such as keyboards and mice) to
+# become inaccessible. Therefore, you should not enable this option if your
+# non-Apple OSes work correctly; enable it only if you have problems with
+# some hardware devices. When needed, a value of "10.9" usually works, but
+# you can experiment with other values. This feature has no effect on
+# non-Apple computers.
+# The default is inactive (no OS X spoofing is done).
+#
+#spoof_osx_version "10.9"
+
# Include a secondary configuration file within this one. This secondary
# file is loaded as if its options appeared at the point of the "include"
# token itself, so if you want to override a setting in the main file,
