MacBook Pro SMC Firmware Updater1.8

This update -- SMC Firmware Updater 1.7 -- is showing up in software update for me and I have a MacBookPro8,3 (17-inch, Late 2011). I wonder what gives? Boot ROM Version: MBP81.0047.B27 SMC Version (system): 1.70f5 Mac OS X Lion 10.7.5 (11G63)

All is fine here. Just ran the firmware on my early 2011 15" MPB. After installation the computer restarted, the fans worked for about 30 seconds at full speed, then a second restart, and thats it.

It might be helpful to word the description as something like "For SOME mid-2010 and early-2011 MacBook Pros." I know I should have read the fine print more carefully, but I have an early-2011 MacBook Pro, and I was initially baffled why I couldn't find the update. (It doesn't apply to 13-inch models.)

My MBP 9,1 (mid-2012) isn't affected, i.e., SU says there are no updates.

Despite no model indication from Apple, only applies for MacBook Pro from 2010 and 2011.

Apple doesn't say, but I think this is only for the most recent MacBook Pros. It's not supported (not for) my mid-2010 17".

The 1.3 SMC update has an unclear effect on temperatures. (It brings me up to version 1.27f2 - go figure.) I was running up to 83C or slightly higher according to iStat, under moderate to heavy load. (The load was an external monitor streaming Netflix, Wi-Fi running at 150 KBps, and several applications. This does not seem like a heavy load to me, but I guess decoding a movie takes work.) Tonight, I went up to 83 without even any streaming (but with an external monitor). But after a few minutes it has settled down to between 72 and 76. Here's my complete temperature list for comparison. First number is first reading; second is 10 minutes after startup. CPU A 82 / 71 Airport Card 51 /52 Battery 30 / 30 Enclosure Bottom 33 / 34 GPU Diode 82 / 79 GPU Heatsink 68 / 65 Heatsink A 62 /61 Heatsink B 46 /45 Memory Controller 52 /51 Hitachi Drive 21 /21

To reiterate, not for unibody MBPs.

Not for late 2006 MBP's either.

Is this meant only for the unibody models?
