Why must I always perform an SMC reset to have proper graphic performance?

Is there a proper fix to this? I am slowly getting angrier and angrier about the fact that I paid so much for a machine, yet I have to reboot every time I expect regular performance from my graphics card. This is completely UNACCEPTABLE, and I'm wondering if I'm missing out on a proper fix that has already been implemented.

So this is what I got when I took my computer into the apple store to have it diagnosed.
After the apple technician performced several tests, the only thing that fixed the issue was an SMC reset. Based on this he figures it is probably a software or firmware issue that is going on. He is a little concerend how ever that the fans of the comupter don't reach maximal rpm when the computer is displaying the issue. So he recorded the problem, and told me to just perform the SMC reset as needed for the next couple months and wait for a new update from apple. If the issue persists I am to go back to the apple store and they will take the appropriate steps.
He said an SMC reset doesn't hurt the computer in any way, so its safe to do. I am gonna contact blizzard and let them know about the issue as well because if it is software, it could be their game (Diablo 3) that is causing the issue as well. If I hear of anything new i will let you know. So get on the blizzard form and let them know of the issue to fix the problem faster.
Thanks for your help,

Why must I reset sharing password every time host computer is shut down?

Using 10.7.5 on iMac desktop. Sharing Internet via Airport card. Every time the host computer is powered down the sharing password must be reset. Have tried using both security settings offered with same result.

Have you disabled hardware acceleration? (not solved by reset is usual)
You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
Then perform these steps:
*Click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
*In the Firefox options window click the ''Advanced'' tab, then select "General".
*In the settings list, you should find the ''Use hardware acceleration when available'' checkbox. Uncheck this checkbox.
*Now, restart Firefox and see if the problems persist.
Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:
* [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]
* [[Upgrade your graphics drivers to use hardware acceleration and WebGL]]

Why does my mac book pro 2012 15" w/ retina display run slow during a video game and then an SMC reset seems to fix it temporarily?

When I begin to play Diablo 3 with my fairly new 15" mac book pro with retina display, every now and then my computer will be really laggy when playing it (frame rate of under 5). Normally its performance is really fast with a frame rate of about 40-60 frames per second depending on the resolution used. When this happens I have performed a SMC reset and it fixed the problem. However, every few days it will act up again and I will have to do an SMC reset again. It has now happened again for the third time and I am affraid to continue to perform an SMC reset, is this bad for my computer? Should I take it in and have them trouble shoot it? Any help would be greatly appreciated to figure out what is wrong. Thanks.

Why does my Mac not restart after resetting SMC ?

I have a MacBook white intel base 2.4 duo mid 2008. I reset the SMC because the message kept coming that was going to shutdown. If you did not select cancel it would shutdown. Since then it will not restart? The choices were sleep , cancel or shutdown . Performe all the trouble shooting I could find it still came up with message
Any ideas
Regards
Denis

how did you do the SMC reset? the following article tells how to do this:
http://support.apple.com/kb/HT3964
use the section for batteries that can be removed to perform the reset then see if it will start up
if it doesn't what OS are you running?

Performed SMC reset

Why the itunes always must sync all data another file if making update application for iphone ?

Why the itunes always must sync all data another file if making update application for iphone ?

I'm not sure I understand the question

Help with BBOD! Can't seem to get to the bottom of it. Have tried SMC reset, PRAM reset, reinstall of Mavericks, Carbon copy clone, checked my CPU, Memory is 500GB and I'm only using 250GB thereabouts.

Here's what I've tried;
SMC reset
Pram reset
Looked at activity monitor - mostly seems OK aside from a kernel task taking up memory (approx 460MB) but CPU is around 96% idle.
Fan seems to be running constantly - heats up noticeably when I close the MBP
Despite a re-install of Mavericks, MBP is running frustratingly slow. Just typing is enough to bring on the beach ball.
Have backed up everything, reinstalled from a clone, checked through Apple Hardware test and carried out a Verify Disk Permission - nothing was reported, erased the drive and set up again - problem still stands.
Memory is running at 3.43 GB without anything really running bar Safari.
A little loath to install SMC fan control without knowing what's wrong.
Checked software updates.
Can anyone tell me what the matter is? Does this have a fix?
Have been reading up various posts but to no avail so have resorted to posting myself.
Does this sound familiar to anyone?
Many, many thanks
Roque

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the request of a stranger. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "syntax error," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.

Macbook Pro Retina crashes after SMC Reset

Hey guys. My macbook pro retina is constantly running its fan at full speed at random times. The fan is always running on high even when I do not have any background apps running. And every time I try to perform SMC reset, my macbook crashes and I have to reinstall OS X all over again. Some other issues are that I cannot update my computer without crashing and having to end up re-downloading the software again. Also, when starting up my macbook on the new Yosemite, the loading bar when logging in gets stuck, which again results in me reinstalling the software or restoring from an old backup. People have suggested replacing the SSD in the computer but I believe it may be the motherboard that may need to replace. I own a Macbook Pro Retina 15" early 2013 running OS X 10.10. And everything is factory when it comes to hardware.

I just bought a new charger and it appears to be working, so looks like that problem was not with my MBP but rather with the charger itself.
I am noticing that my fan is a little quieter now, but still doesn't sound normal. I have looked at Activity Monitor and nothing is using a lot of CPU at all (highest is Chrome at 6%). The MBP does get hot when the fan is going. I have looked at videos for cleaning/replacing the fan, which I think may be a good idea, but I don't have the proper tools at this time. It's something I'll keep looking into.
Also, Chrome and Mail both seem to be working now, randomly, even though I haven't done anything else. It's weird that they both stopped working immediately after I did an SMC reset, but maybe it's just a coincidence?
I will do another SMC and PRAM reset if further problems persist. Thanks for all the help!

My Macbook pro when plugged in will hold a green light and not be recognized by the computer to charge. SMC reset done several times. Any help?

Our MBP bought earlier this year when plugged in to charge will hold a green light and not be recognized by the computer as charging. Sometimes if we turn it around or plug it in multiple times will work. We have reset the SMC several times and will work for a little while then go back to the same problem. Any help or ideas on how to fix it would be great.

Hi Why must I,
I'm sorry to hear you are having charging issues with your MacBook Pro. It sounds like you have been on the right track in troubleshooting this issue; SMC resets are often an appropriate step for battery or power issues. If this issue persists, you may find the additional troubleshooting steps outlined in the following articles helpful:
Mac notebooks: All about batteries - Apple Support
OS X Mavericks: If your battery won’t charge
Note: If you reach the last step in the second article and it looks like you may need to have your MacBook Pro serviced, you may find this page useful:

HT3964 SMC Reset Not Working

Tried suggested steps for SMC reset and battery still not charging. Mac is not remembering preferred networks and won't access the internet. Any suggestions?

Reinstall Leopard.
How to Perform an Archive and Install
An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.

Apple says "logic board needs replaced" because MBP won't turn on w/o SMC reset but I think I can fix it; can you help?

Hello,
Less than a year after purchasing a brand new, early-2011 Macbook Pro (still covered under Extended Apple Care) and, sadly, only a week or two after finally upgrading to 8GB RAM, I returned to my notebook after taking a shower and watched it suddenly shut itself down. It has not been responsive to the power button since then (although, see below.. I think I can fix it).
Genius Bar took one look at the visible moisture sensor you can see underneath where the RAM sits and declared it water-damaged. While I agree that either a short and/or corrosion is causing my MBP to malfunction, I don't believe it should void my warranty because the problem isn't that I spilled something on it.1
I hope someone can give me some insight into fixing this myself. Apple says "the Logic Board needs replaced" (a common CS response, I've noticed) the water damage voids my Extended Care + that it'll be at least $1200 and several weeks. Here's the situation:
MBP will not turn on just by pressing the power button. However, MBP consistently (every time) powers up when I do an SMC reset.
I have it in verbose mode and it begins booting. But, it will invariably turn off without warning anywhere between 30 seconds and 8-10 minutes after powering up.
MBP will not turn on just by pressing the power button. However, MBP consistently (every time) powers up when I do an SMC reset.
I have it in verbose mode and it begins booting. But, it will invariably turn off without warning anywhere between 30 seconds and 5 minutes of powering up.
Eighty percent of the time, it turns off during the pre-Xorg boot. However, I have also seen it fully boot, I log in, I'm able to peruse logfiles/etc. Safe Mode (holding shift) crashes early. Single-user mode makes no difference. PRAM/NVRAM/etc makes no difference. I can boot to the Recovery Partition but it turns off just the same (disk utility scan takes too long).
I haven't been able to really test the Internet Recovery because the hotel wireless takes too long. I did boot into Hardware Test and it passed the basic and extended tests (although it seemed to just be testing the RAM integrity.
I can boot from the optical drive with a FreeBSD 9 livecd and an Ubuntu 11.04 livecd. Of note is that the laptop shuts off consistently when FreeBSD begins the journaling services for the ZFS filesystem (every time).
Here is where this leads me to believe I'm at (I am not dogmatic here and would appreciate any corrections or insight):
It seems like there may be corrosive damage on the logic board but maybe it's isolated given the various consistencies in what's happening. It seems like whenever SATA is use, I lose power. When SATA isn't really used (the HW Test), the laptop has literally stayed on for days and days.
I want to get in there and clean up any corrosion with 91% isopropyl alcohol (9% distilled, non-conductive water).
I want to use a bootable OSX livecd with an "emergency console" so I can, basically, use boot options to step throught the boot process and see if I can isolate the problem.
Here is what I'm uncertain about and could use guidance:
Does any of this sound remotely reasonable to anyone who has been through this or am I delusional?
Any tips on identifying and cleaning any corrosion?
While I had made a bootable version of Lion via Disk Utility and a rescue disk with some third-party app, they are MIA and I don't have another Mac at the moment. Do I have any other options? Again, an install dvd is not exactly what I want -- more like a rescue dvd. I had read about some Apple Stores giving/copying bootable USB thumb drives like this to customers. But, I noticed that this is now on sale there for $80. I would use this like once and, ideally, could use my MBP to make more. $80 seems a bit much.
I should be able to step through the boot process in a way like what's possible with FreeBSD, no?
Anyone have any other specific troubleshooting tips?
I really, reallly need my MBP back as soon as possible. I'd really appreciate any wisdom and insight! Thank you,
-ryan
To be totally honest, about 3 weeks prior I spilled some milk from cereal on the desk and a little bit got onto the battery. However, the notebook worked fine for the following weeks. I believe that the problems have been caused by ambient humidity ... I've been staying in a hotel that steams up the entire room when I take a shower. The windows are covered in water droplets so why wouldnt the MBP be affected? As noted, these problems began after I lingered in a hot shower.

I don't think you have a case.
You can replace the logic board yourself if you are a DIY'er and save some money.

13" Air has required SMC reset twice due to weird behavior (fan, backlight)

Note: MacOS version is really 10.6.7 plus Supplemental Update for the 13.3" MacBook Air.
My MacBook Air 13.3" 2.13 GHz/4GB/256GB, purchased in late November 2010, has twice now started acting weirdly after I installed MacOS 10.6.7 Supplemental Update. Resetting the SMC ( http://support.apple.com/kb/ht3964 ) solves the problem, but I'm getting worried because it's happened twice now in a few days.
Symptoms:
Even though I closed the lid with MacOS running, putting the machine to sleep, it either refuses to wake from sleep, forcing me to hold the power button to force it to reset, or it automatically performs a cold start and boot when I open the lid.
When I turn the machine on, the screen backlight is turned to maximum, regardless of previous setting.
When I turn the machine on, the fan(s) start running at full speed, regardless of temperature or load.
When I turn the machine on, it lingers for a long time at the gray screen before the screen turns blue and MacOS loads.
When MacOS has booted, the menu bar displays a battery icon with an X inside it. When I enter System Profiler and click Power, it reports that there is no battery installed. It also reports that the machine is connected to an external power source, even if that's not the case. It does not identify the external power source.
When I connect the external power adapter to the machine, the light on the connector does not come on (no light at all, neither amber nor green).
When I perform a shutdown, the machine will power off. However, handling the machine (with the lid closed the entire time) will repeatedly cause the fan to come on for a few seconds at full speed, then stop.
Resetting the SMC will fix these problems and cause the machine to perform normally after the reset. However, after leaving the machine sleeping for approx. 12 hours after a few hours' use after the first reset, the problem reappeared and the machine cold booted when I opened the lid, forcing me to shut it down and perform another SMC reset.
I'm worried this problem was either caused by the Update to 10.6.7, the Supplemental Update to 10.6.7 for the 13.3" MacBook Air, by an unrelated firmware bug or of course by hardware problems.
Anyone else out there with the same problem/symptoms? Anyone care to venture a guess as to what the problem is?
Thanks,
Gunnar

Hi,
I have an update so I thought I would share in case any other users are experiencing a similar problem.
I made an appointment with the Genius Bar at the Apple Store.
I went in and they ran a thorough diagnostic check on my Macbook Air and determined that the sensors were indeed faulty - several were providing no information "No reading" instead of providing a temperature. Thus, the Air was unaware of the temperature across multiple components.
Despite the laptop being outside the 12 Month Manufacturer Warranty, the Apple Store determined that it was covered under warranty through Australian Consumer Law - the laptop is now in for a complete repair under warranty at no cost to myself.
I couldn't be happier.

Keyboard Backlight not working after SMC reset

I have a Late 2009 MacBook Pro, and I noticed that the backlight for my keyboard stopped working last night. I Performed an SMC reset and powered the computer back up. Again the backlight never came on, but I noticed that if I pressed the keyboard brightness buttons the icon that used to show on the screen showing what the brightness is at, (like the volume one), was not showing up anymore. I checked the keyboard settings and noticed that the auto brightness for the keyboard dissapeard. Anyone have any suggestions?

try to reinstall your firmware, im having the similar problems, but reinstalling wont let me.... http://support.apple.com/kb/HT1237

Why must I always perform an SMC reset to have proper graphic performance?
