Latest SMC Firmware update causing problems?

Hello,
recently, I've attempted to install the update: MacBook Pro SMC Firmware V 1.7 and had issues booting up my system afterwards. I thought I ran my RAM down to its skivvies and it was rebelling, but it seems to work fine after repairing the disk drive using Disk Utility, because the first time it happened my Mac wouldn't open things as fast as it usually did, taking about 10-15 minutes to get to the login screen, and then some to get back into the desktop. After shutting it down and rebooting it wouldn't get past the Apple loading screen after the tone. Even with repairing the drive after installing the update, it wouldn't load past the tone and the Apple loading screen, so I restored the system from an external hard drive. This seemed to do the trick and allows me to do everything I used to do prior these problems, and the second time I tried to update the SMC V 1.7 it caused the same problem.
I wondered if anyone else was having these problems with their Macs in regards to the SMC, and maybe it isn't just the SMC but other parts of the MacBook that have problems. Specifically, the Mac I'm using is the 2011 MacBook Pro6,2 2.66 GHz Intel Core i7 with Snow Leopard version 10.6.8. The SMC that I have currently is the 1.58f16 .
Then again perhaps my disk drive and other components are stating their wish to retire. I've used it pretty hard over the past year.
Thanks for reading,
Dracien

Not on my Late 2011 15". But others have had some problems.

Firmware update caused problems with HBD-N790W

Latest firmware update caused my DVD Blu Ray Home Theater to lose the ability to find internet video content. The unit shows that the 12/19 update was successful. I can access the internet and get web browser content--so there isn't anything wrong with my wireless web connection. My unit shows the connection to the internet is working. I made a YouTube video about it:https://www.youtube.com/watch?v=9nqYNNVPcBA&list=UUNQaJbjyKQwFlZXY6832mIA The set-up feature does not work and I lost my video channels (Netflix, Amazon). I don't really understand why my connection to the internet works, my wireless works...everything works except getting updated media channels. I have tried plugging and unplugging cable, modem, wireless, unit, for ten minutes many times. I reconnect the unit to the web...get buttons that say that internet content can be updated...press the button...then the Sony logo and it stops there.

Hi, i work for a Service center for walmart and bestbuy and i have been getting this model in for service for awile now, after a firmware update the systems have reported to work good till there turned off the first time and then they dont book up all the way, you will get a Sony logo at top left screen and the Blue Bluray Logo in the center of the tv screen and thats it, no menu functions the controls on the player it self flash on and off slowly you can turn the system on and off with the remote but thats it, this looks like a failed firmware update but there seems to be no way to reflash these even with the firmware you can get from the sony site you have to burn a CDR disk but becuse there is no menu you cant get that far, i have 19 of these units stacked up 5 have been replaced with other brands to make customers happy, the rest on still in wait for a fix, its looking like replacement of main board will be the next step in this night mare. if sony tech wants to shine some lite on this now i would be very gratefull. Thanks Chris R.

Firmware update caused problems with G4 AGP

Greetings all,
I have a great G4 Sawtooth 400MHz which I intended to upgrage by installing an OWC 1.2GHz processor using the 7455 chip which I was informed did not necessitate a firmware update to 4.2.8. After installing it, the machine would turn on but would not boot. OWC tech confirmed that I did indeed need to update firmware to 4.2.8 and that this had to be done while running under OS 9.2 which resides on one volume of my partitioned hard drive while OS 10.4.10 is on another volume. I reinstalled the 400MHz processor, changed the startup disk to OS 9.2 and carefully following Apple's proceedure successfully upgraded the firmware which now reads: $0004.28f1. All this went off without a hitch of any kind. OS X was then selected as the start up disk but the machine will only start up in 9.2.2 no matter what I do.
Attempts to boot from the OS X Install DVD holding down C key simply results in a blinking "?" mark indicating that OS X is not deemed to be a useable OS. This is confirmed by opening the DVD on the desk top after booting into OS 9.2 and choosing "install OS X". A message then appears : "Mac OS X cannot be installed on this computer. Please consult the documentation for the list of supported computers."
Other anomalies are: Only an instant of start up chime occurs. Of the 312MB installed only 64MB is recognized. System profiler indicates PC100-322S is recognized but the PC100-222S is "Not compatible". Sometimes the startup device is shown to be the volume containing OS X but the top disk shown on the Desktop proves to be the OS 9.2 volume. Only a quick LED wink of the caps lock key occurs when attempting to reset PRAM, no audible chimes. Starting with option key down produces an image of the two volumes and arrows but does not permit selection and will not proceed from there. Attempting to boot from a firewire drive with several bootable OS X volumes does nothing more. Booting from a Norton Systemworks 2.0 CD to check the OS 9.2 volume for errors changed nothing.
I have removed the battery for two hours before reinstalling with no effect. The battery is at full voltage of 3.6V. I have reset the S1 switch (PMU I think?) several times. I have started in open firmware to reset-nvram, set-defaults, reset-all. Nothing, absolutely nothing I have done changes a thing.
The machine is usless to me running only on OS 9 so I would be grateful for any suggestions or information as to how I could install an earlier version of firmware which may again run OS X as it has for many years. Although I think the problem is that it now identifies itself as a very early processor type which is not compatible with either the ram installed or OS X but I don't know how to tell the thing diffrent!
Thanks

Thanks Dave,
You are a genius. I can't tell you how much I appreciate being benifit of your knowledge and willingness to share it with others. A thousand times over, thank you!! I burned the little utility to a CD on another machine/setup, ran the little sucker and restarted in OS X like a hoot!!! About 8 minutes later I had the processor upgrade installed and see quite an improvment. Again, thanks and kudos be upon you,
James

RV016 firmware update causes problem.

After updating firmware to 3.0.0.19 on our RV016 router the log file is showing an error about every 70 seconds.
Event type: Authentication Failure
Message: 2010/02/24 17:20:34 Bad login attempt for user: (null)
It doesn't seem to have any affect on the system but I would like to know what is causing it.
Thank you.

Hummm ... I do not see anything in the release notes. Will be interesting to hear what others mention.
Do you have two consoles open from separate machines, or some monitoring open? Every 70 seconds sounds like there is a process running in a browser or machine ... if it was occasional, I might suspect someone trying to get to the admin pages without logging in first.
Maybe a scan for unsecured web pages across the network.
If no one on this community helps, and you feel it needed, I might suggest a quick call to our support.

Having problems with SMC Firmware Update 1.8

I installed the MacBook Pro SMC Firmware Update 1.8 yesterday and have since experienced a number of problems. I am running a 15 inch, Mid 2012 MacBook Pro, btw. First, after the intial install the sytem would not reboot. I had to do a physical reset of the SMC controller to get the system to power on again (sft-cntl-option-power key sequence). Once the system rebooted, the fan in stuck on high and the battery meter in the controll bar does not show status, just displaying an "X" in the battery. I went into the Software Update utility and the SMC update is still listed as available, I tried reinstalling it, and the situation has not changed. The fan noice is annoying and I'm aftraid to disconnect the laptop from the AC adapter. Please advise.

Firmware updates don't affect to Windows and OS X. The firmware makes your hardware work, not the operating system, so you won't have any problem doing this

Problem about SMC Firmware Update 1.7

So I was browing and suddenly a notification pops up about OSX update. It was about SMC Firmware Update 1.7
I am using a MBP 15" Late 2011. ( OSX Version 10.8.2 )
I did clicked update and it asked me to restart. But instead of a restart it automatically logged out. So I logged in and clicked Update and then when it asked me for restart it clicked restart. So now it showed me a Grey screen, the cursor was still there. The cursor was still moving. So I though now this is getting updated but it didn't showed any window of Software update for 20 mins. I assumed it was downloading the update.
The update is just 1 MB or something and I have a connection of 2Mbps so 10 mins were too long I guess. I had to shut the mbp by holding the power button. after 2 mins I press the power button. it started and showed the window of software update and downloaded it automatically and updated, fans went on full speed as mentioned in the update.
Now that I check my firmware version. It shows me " SMC Version (system): 1.69f4 "
My question is shouldn't it be SMC Version : 1.7 ? :|

That's the right FW version. Apple is all screwy with numbers. There posted FW update 1.7 mean just about nothing.
If you want to save yourself a few headaches turn off the Auto Update system and then periodically run Software Update. If there are updates look at what they are and you can pick and chose which ones you install. If you don't need it, the system is running fine, there is no good reason to constantly do updates.
This also give you a chance to look at the support document for the update and do a google search to see if there are any problems being reported.

Problem with SMC firmware update.

I can't seem to run it. Everytime I go to, it never installs. I have a feeling that it has to do with bootcamp. Whenever I restart my computer, it runs Windows (I don't know how to fix that.) so I can't just press restart, I have to actively start OSX.
I go to install it, my computer starts up, and then the installer pops up again. I press restart, start up the computer, same thing. I've done this 4 or 5 times and the same thing happens everytime. What should I do?

Sheir,
Go to System Preferences>Startup Disk and verify that OS X is the Startup OS that is selected for your Mac. If it is not the one selected, select it and restart your Mac a couple of times to verify that it will restart into OS X. If it won't then we need to figure out what is going wrong.
If it successfully restarts into OS X then go to Applications>Utilities and look for the SMC Firmware Update.app that should have been placed there and trash it. Also trash the SMC Firmware Update.dmg if you have it. I don't think you will because Software Update has been doing the install. Empty the trash.
Then go to Apple Downloads and manually download a fresh version of the iMac (early 2006) SMC Firmware Update released on 16 MAY 2006.
Shut down all your other programs except the Finder and Dashboard. Unplug everything from your Mac except your USB keyboard and mouse. Turn off Airport and Bluetooth if they're on.
Make sure you are completely familiar with the SMC Firmware installation instructions.
Try to do the install again.

Unable to apply SMC Firmware update

I am trying to apply the SMC 1.0 Firmware Update to my MacBook Pro. I click restart in the firmware update dialog, and the Mac reboots. I then see a folder with a question mark flash three times, then the Mac boots to OS X. I have tried numerous times from both warm and cold boots, but the firmware update will not start.
I then tried to zap the PRAM, and attempt the firmware update. After doing that, the folder with the question mark flashes only once, then the Mac boots into OS X.
I have downloaded the firmware update multiple times both through Software Update and via the web, but each time the result is the same.
I have used Bootcamp to partition the drive. I am not holding the Option key down while the Mac boots, but I did try that once, and it did not help. OS X is my default OS.
Any other suggestions?

I have a feeling the problem was due to lack of free unpartitioned space on my main harddrive. What I did to solve this was buy an external Firewire drive, install OS X on it, then use it as the primary boot drive to do the firmware update. I am now running the latest SMC firmware. Let's see if it really helps the temperature problem.

Macbook (late 2006) RSS unable to install SMC firmware update

Hello,
I bought my macbook on the 27th of December, and the first week it worked fine. Then started the RSS. I did some googling and found out some stuff about RSS, tried to install the SMC firmware update but it would just tell me that I don't need the update. After two weeks of constant RSS:ing I called applecare and told the guy about the problem, he told me to try to update the SMC and if I can't do it bring it in for service.
Monday the 15th of January I went to the macstation in downtown Vancouver and told them about the trouble, they tried to boot it, and it actually booted but after like 3 minutes the macbook crashed. For about 10 minutes two guys tried to boot it and so on, but they didn't get it to boot. So they took it in for service and somebody was going to check out the macbook and see if it would need a replacement logic board - which it did. So on Monday they ordered the logic board, and today Monday 22nd of January I got it back. Now the thing that bothers me is that when I now try to update the SMC firmware (my current version is btw 1.13f3) it still just says that This computer does not need this update. oh well - i went to apples support page to try to see if there would be a newer release of the smc and then I noticed that in the bottom of the SMC firmware 1.1 update page it says:
Note: This update is only or the original MacBook, and will not install on a MacBook (Late 2006).
Then I really was like W T F?!
I would assume that people who work for apple would know that the SMC update will not update on a computer from late 2006, but nobody ever mentioned this to me.
I've now had the computer for about an hour and the CPU temperature is at about 50 degrees celcius, with firefox, msn and a terminal open... about 5% cpu load.
What I'm really wondering is that is there anyone who has similar problems with a macbook late 2006? I guess I'll just have to see if it works and just like I told the guy at macstation, if it starts RSS:ing again I'll be banging on their door

MacBook Pro SMC Firmware Update 1.3 update freezes mouse pointer

After installing the update released today 5/28 (MacBook Pro SMC Firmware Update 1.3) my mouse pointer stalls, freezes on occasion. Very annoying. Anyone seeing the same. Fixes ... ?

After applying the SMC Firmware update a few days ago, my keyboard and trackpad were acting erratic (freezing, hanging). It was immediately after the update and I had not had any problems with it before.
I have also had random crashes, inability to use the keyboard/trackpad ever since.
Today my keyboard and trackpad are completely unusable, external mouse works fine.
I will take it to an Apple store tomorrow, hopefully my firmware can be reverted.
Sounds like a lot of other people are having problems with this update. http://discussions.apple.com/thread.jspa?messageID=9549034&tstart=0#9549034

Recent smc firmware update......

it's not that i'm having any problems and really don't expect to, however, i'm a little concerned about the new update. i know it may stop rsd from occurring, but at what expense. is it simply disregarding a malfunction that is actually taking place, so that in time something more sever may occur.
it's only a concern that i haven't heard on here yet, although i would like to hear what people's opinions are.

I myself have installed it and have not had ay problems...
Here is something that I found for you.
"MacBook SMC Firmware Update 1.1
About this update
The SMC Update improves the MacBook’s internal monitoring system and addresses issues with unexpected shutdowns. This update is recommended for all MacBook systems, including those that received warranty repair."

Is SMC Firmware Update necessary?

Hello there
I have the Software Update window popping up telling me to download the SMC Firmware Update. I know that the update adjusts the fan behavior in the MacBook but does anyone know exactly what it does and changes?
My MacBook has been working fine since I got it in July. No weird fan behavior nor RSD nor overheating problems (thankfully! I'm hoping it stays that way). So my question is do I need that update, or is that update only for users with those problems? If I download it, how does it alter my MacBook behavior?
Any advise is appreciated! Thanks in advance.

Honestly I was kind of like you. I downloaded the firmware but didn't install it for quite a while. My MacBook as worked fine and I saw no reason to screw that up.
But..... it got the better of me and I went ahead and installed it. I haven't noticed any difference whatsoever. Fan behavior is the same I guess because I've only heard them a couple of time so that's never been an issue. I guess it may run a little cooler but again I don't really pay that much attention to the temperature anyway so I'm not sure.
SMC is System Management Controller which is a micro-controller on the logic board that controls various functions (in this case the fan). I've never found anything specific other than some have said the fans run non-stop. Could be but I've experienced nothing different than before I installed the firmware.

SMC Firmware 1.1 problems?

I recently updated to SMC firmware update 1.1 and as soon as I rebooted the temperature of my cores jumped from 38c for core 1 and 39c for core 2 to 50c each. Both the temperature monitor widget and application say the same thing. Is this a problem with the apps or the firmware itself? I know 50c is not that hot but I was more comfortable with 38 and 39.
MacBook 1.833 Core Duo Mac OS X (10.4.8)

bronyruar,
my MacBook used to run at 68 or so when I first bought it. After the first firmware update, it went down to the low 50s. Then, possibly due to some other update I started getting readings of 20-22C! (Which is pretty improbable) I kinda gave up on the temp readings after that.
I just updated as well, and now iStatpro shows me at 45C, which seems plausible.

How to reinstall SMC Firmware Update?

Hi,
I've an issue with my fans: after a SMC reset , they're doing fine until I put my MacBook Pro to sleep; then they are stuck at about 2000 rpm, independent of the CPU temperature, so that I've to reset the SMC again to fix it temporarily...
Would like to reapply the SMC Firmware Update to see if this help; does anybody know how to do this, as upon starting the app, it just tells me that I'm already at the right version and there's no Apple Firmware Restoration CD available for the new Macs from late 2008 available (yet).
Any help's highly appreciated!
Thanks and best regards,
Michael

That's quite normal.
haha oh wow... did you guys actually read what OP wrote?
@ OP, read here: http://discussions.apple.com/thread.jspa?threadID=1823105&tstart=45
obviously there's nothing you can do up to get your mbp replaced to hopefully get a working one. i don't think apple will EVER fix this problem, cuz it exists since release. just like many other issues apple never fixed...
