Should I update my SMC firmware?

I use YES method to keep my both cores runing in its full speed over 7 seven minutes and returned no any random shutdown. Should I keep updating my SMC firmware?
My Macos is 10.4.6 and SMC is 1.4f8. I didn't have any update since this July.

Holding CPU at full load for 7 min without a problem does NOT justify that you don't need the updates. RSD usually takes time to develop. Despite of all the application updates, 10.4.8 and SMC firmware 1.4f12 are the two things you must have. They will make ur macbook run cooler by changing the fan behavior so you won't be pushing the limit of ur macbook as much as before.
Don't hesitate. I know some people think getting updates might not be a good idea after reading so many posts here. But keep in mind that this is a forum for us to report problems. The guys who never had a problem with their macbooks (which i tink is the majority) may never post here. Updates are not supposed to cause any problem, otherwise they wouldn't be released officially, don't ya think? If you did run into problems after update, it's ur macbook that is wrong, not the updates. It'll be better off that you just reinstall the whole OSx and get all the updates to obtain a clean system.

I just recently installed mountain lion and an update for SMC firmware to install power nap. Everything is working except for the menu bar, the icons native to the system do not respond, and features like the clock and battery meter freeze.

I just recently installed mountain lion and an update for SMC firmware to install power nap. Everything is working except for the menu bar, the icons native to the system do not respond, and features like the clock and battery meter freeze.
When I mouse over the icons, the rainbow appears as if it was processing something. The problem is eliminated when I restart my computer but it comes back after a while.
I guess I cant make a backup copy and restore the whole disk because the copy would be made with this error.
Can anyone help me? Anyone with the same issue?

Update: I was able to test out the HDMI adapter as well and the same issue occured. I'm stumped. 10.8.1 maybe.

Should I update my WRT54GS firmware?

I have a WRT54GS V1.1 router. I haven't updated the firmware since I bought the router in December, 2004. It is currently at version 3.37.2 of the firmware. The latest version is 4.71.1.
Should I risk a download?
I'm trying to get my daughter's new notebook to work off the router. We haven't tried everything, but I'm wondering if I need to update the firmware. It always seems that updating or upgrading software causes more problems than it solves.

If you are not having problems with that yet, don't... it's like a last resort thing...

Should I update Intel MEI Firmware or not?

You know, there is this little chip on every last-gen laptop's motherboard (apple macbooks either) called Intel Management Engine Interface (MEI), and it has its own firmware that is upgradable. I'm currently running Windows 8.1 via Bootcamp on my MacBook Pro 13 (Late 2013 Retina, Haswell based), and it has the Intel MEI Firmware verion 9.5.3.1526, you can check it yourself using Intel MEInfo Tool (detailed info here):
The question is, can I update this firmware with the newer one that is available (version 9.5.41.1904) here? Is it safe or not? Anyone tried?

The benefits are the same as with BIOS\EFI update like bugfixes, improvements, etc. Probably, this new firmware resolves the known 30% CPU Idle issue, I don't know, but I want to try.
You may want to create a system restore point before you update, so you can roll back easily.

Apple boards are nothing but the same Intel boards with Intel chips and logics using some kind of custom design, so I think it is not so much Apple-related thing.
Apple has written a lot of their own firmware, the latest example is the iMac 5K with ATI cards, which have issues with WHQL drivers. GPU drivers are also similar. Another example is the absence of WiDi on Intel hardware, since Apple has their own AirPlay. It is worth a test, if you keep careful backups of Windows and the OSX to be prepared for disaster.

Norton Live Update after SMC Firmware Update

It freezes my screen when it's trying to "update everything" (the cursor still moves but nothing can be clicked). alt + apple + esc doesn't bring up the force quit dialog, i have to manually press the power button to shut it off.
does it have anything to do with disk repair permission or something?
i don't have any trouble with boot and reboot though

Hi Resno,
Click the link and you'll be taken to MacFixIt, where you'll read that Symantec are aware of the crashing problem, and how they are in the process of fixing it. http://www.macfixit.com/article.php?story=20060517112611193&query=norton
With regards to anti-Nortoners (whose comments are actually amusing !), if Symantec is unfit for Macs, then why in the previous issue of MacFormat magazine, did they have a competition to win 1 of 20 copies of Norton AV 10 ? Also, why, in this month's MacFormat,the UK's best-selling Mac magazine, have they given a decent write-up about Norton AV ? A specialist Mac magazine favoring a, as what some have called, a 'virus' ?!
We are all entitled to an opinion and I am not having-a-go at people who dislike Symantec. However, Resno has a point when he queries if the anti-Norton brigade have actually installed and tried Norton AV, rather than just reading critisisms about it.
Once again, though, to all who hate Norton, with your slanderous attacks on the product, I would like you to know that your crazy comments bring a smile to my otherwise miserable face !

SMC Firmware Update Locks my mini

I got an auto update for SMC Firmware Update for my Mac mini [early 2006 w intel solo].
After running the auto - uptater it asked me to restart my computer. Once I did, my mini will not respond but the SMC Firmware Update looks to be running.
I have done the following:
• Made sure my mouse and keyboard work. They do but the mouse cannot click on anything - just move around.
• Tried to command-Q - doesn't work.
• Restart - doesn't work.
• Tried to restart with holding down the power button. Got the flashing power light and tone but - doesn't work.
• Tried force quiting with command-option-escape - doesn't work.
• Tried looking for some form of support out there - doesn't work.
Can anyone out there give me a hand?

I am in the same situation - am presently running under "safe boot". It´s the only way to communicate with the **** box! Have tried numerous attempt to let the machine restart, and left it as long as a day in this state, in case there is something going on in the background, but in vain.
So far it always looses contact after the initial boot, with the screen looking "dumb hazy blue".
Is there a way to uninstall the SMC Firmware Update -anyone??
And, by the way - to call this issue solved with the given resolve - isn´t that a little like telling a man with a broken leg that he should see a doctor?

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

HT204032 Can't install SMC firmware update

I'm trying to install the SMC firmware update 1.6 on a mid-2011 Macbook Air. First downloaded it from App Store, and after restart it was stuck at a gray screen with spinning icon, no text or progress indicator-- stayed that way overnight. Tried downloading directly from Apple, same result. Tried resetting SMC, then installing, same result. It won't finish instlaling the update-- any ideas?

Check your system profiler ...if your SMC is up to date it will read: SMC Version 1.4f12. If it is not and you have the first gen. Macbook (CoreDuo) then make certain that you are running 10.4.8 before you begin the update.
Make sure you are following these instructions explicitly...
To update the SMC firmware on your MacBook:
Your computer’s power cord must be connected and plugged into a working power source.
1. Quit all other open applications.
2. Click Restart in the MacBook SMC Firmware Update window and wait for your computer to restart.
The SMC firmware update starts automatically. A status bar indicates the progress of the update. During the update your computer fans will run at full speed, but will return to normal once the update completes.
As the instructions say - you have to restart the machine via the installer. Also, you do not mention but did you have a status bar appear during the update?

Upgrade problematic SMC firmware 1.7 on 2011 MacBook Pro before OS X upgrade?

I'll soon be installing OS X Mountain Lion on a 15" early-2011 MacBook Pro (8,2) currently running Snow Leopard (OS X 10.6.8). Should I upgrade its SMC firmware to the problematic v1.7 (which had number of battery-related or system-power problems reported about it in early 2013, if not since then) before the OS upgrade? (This firmware update was put out to users to "address a rare issue on some Apple notebooks where a battery that has accumulated more than 1000 charge cycles may unexpectedly shut down or stop functioning”; my Mac's battery has gone through just 352 cycles.)
Apple's EFI and SMC firmware updates for Intel-based Macs table says my Mac should have 1.69f4 (SMC 1.7), but that table as recently as mid-April this year listed instead 1.69f3 (SMC 1.5) as what my Mac should have (and that's the version it does have); and the current download page for that firmware, MacBook Pro SMC Firmware Update 1.7 (though dated Dec 12, 2012) says it requires OS X 10.7.5 or 10.8.2 - Lion or Mountain Lion.
I seem to remember that SMC firmware version disappearing from my Mac's Software Update listings, some while after I'd kept putting off choosing to install it because of the problems I'd read about it (including at least one reporting nightmarish troubles on same machine as mine) and because it didn't seem critical at my stage of battery life. Given the apparent ambiguity about which SMC firmware my Mac should or can have, and ensuing unwanted troubles after installation reported by at least a few folks, can I confidently install Mountain Lion without that SMC version, and then try to install it afterward?

Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Repair Database. If that doesn't help, then try again, this time using Rebuild Database.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. (In early versions of Library Manager it's the File -> Rebuild command. In later versions it's under the Library menu.)
This will create an entirely new library. It will then copy (or try to) your photos and all the associated metadata and versions to this new Library, and arrange it as close as it can to what you had in the damaged Library. It does this based on information it finds in the iPhoto sharing mechanism - but that means that things not shared won't be there, so no slideshows, books or calendars, for instance - but it should get all your events, albums and keywords, faces and places back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

SMC Firmware 1.4f12 has stopped my RSD (and increase speakers volume) but..

My black MacBook week 23 began RSD about a month after purchase. Initially I blamed the meditarranean summer, that's usually hotter than the suposed MB operational range of 10-35Cº. Finally, when RSS went worse, in mid September I called Apple and got a case number, but I didn't send for service because early repairs get RSD again more sooner than later
Following some hints on forums I almost reduced to zero the RSD ocurrence in normal use, but the MB kept on crashing under yes >/dev/null/ & test on cold or warm, but not on hot.
Yesterday October 26 I installed the SMC firmware 1.4f12, and I haven't had no more RSD even with the stress test. Although it's soon to consider an ultimate solution (if some wire isolation is melted/damaged by heat, no firmware update will fix it) I consider a big step ahead that RSD can be avoided by ignoring the erratic temperature sensor data that suposedly the overheated wire defect caused
Anyway, let's see if it works for all (or at least most) the affected, mine was not one of the worst cases, but some users claim to have had RSD after this firmware update, so let's wait and see
By the way, have you noticed an increase in volume on speakers? I've had, and some other users too, but some don't. I don't know how it can be related to firmware update, but it seems to be somehow

You should check if the SMC firmware update is actually installed, in Applicatios/Utilities/System profile Hardware is the SMC version that should be 1.4f12 after last update.
If you don't have the SMC firmware update application in the Applications/Utilities something in the download and installation process seems not correct, because after downloading you must do the actual update from that application with some warnings about being plugged in and don't interrupt the process.
The fan behaviour has improved on my MB after that update, sounds estrange yours is not. But maybe my Fan Control applications have somehow change that, I use smcFanControl and Lobotomo Fan Control, search the web if interested, I prefers the last one because it gives more options thatn smc

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.

Should I update my mini's firmware?

i have a mini part number MB138LL/A (mid-2007), bought in november 2007.
its boot ROM and SMC version are:
Boot ROM Version: MM21.009A.B00
SMC Version: 1.19f0
at this page (http://support.apple.com/kb/HT1237) i see these firmware updates for the mid-2007 mini:
Mac mini (Mid 2007) MM11.0055.B08 (EFI 1.1) 1.3f4 (SMC 1.0)
should i run these EFI and SMC firmware updates?

If you download any firmware updates if your model does not require the update when you run the installer it will tell you and it will quit.

MacBook Air SMC Firmware Update v2.0 update available again and again. How do I fix it?

I have installed MacBook Air SMC Firmware Update v2.0 three times and I still get an update available notification asking to install it again. This is a mid-13 MacBook Air running OSX 10.9.3. System info lists the SMC version as 2.13f7.
Does anyone know how to resolve this issue?

Hi,
- Are there any status or error messages in /var/log/install.log
- The Firmware version it should install is 2.12f137
- If there isn't anything in the log try:
Intel-based Macs: Resetting the System Management Controller (SMC)
and/or About NVRAM and PRAM
and check whether there is installation.
If no install, try OS X: What is Safe Boot, Safe Mode
then reboot normal, try the install again.
Hope this helps
