Yesterday I did and I have now (3): hw.mds_disable_state: software IvyBridge. I am confused.I have FreeBSD 12.0-RELEASE (amd64) installed on iMac 11,1 (late 2009) and I have: "The iMac "Core i7" 2.8 27-Inch Aluminum (Late 2009) is powered by a 2.8 GHz Quad Core Intel "Core i7" I7-860 (Lynnfield/Nehalem) processor with a dedicated 256k level 2 cache for each core and an 8 MB shared level 3 cache." Thank you. --=20 =E2=80=9CHappiness is the meaning and the purpose of life, the whole aim and end of human existence.=E2=80=9D =E2=80=95 Aristotle
