Resetting PRAM & resetting SMC
Okay I was explained to do these 2 steps to try & fix the crashing problem ever since downloading & installing the recent Leopard update.
First of all, holding down the, ControlOptions letters P+R doesn't do anything except give me a quick repeating "chime" (as if I'm doing something wrong, which I must be). Second, this is supposed to be done at Start Up. Is start up at a different time on a mac as that on a PC? I'm holding down these buttons right after I hit the power button, is this the wrong time?
Lastly, & this one really doesn't make any sense. I was told to unplug the power cable & hold down the power button....WHAAAAT?? How does holding down the power button AFTER unplugging the power cord do anything. There's no power!!
Sorry for the spelling or grammer but I'm typing as fast as I can so I can get this out before Leopard "decides" to crash AGAAAAAAIN!!!! Could Apple just send a fix for this?? I'm not an IT guy.
Holding down the powerbutton after unplugging is to be sure that all the capacitors and other energy storage devices are run down to zero.
When you unplug your computer there are some things that still have some small amount of power or energy in them. Attempting to turn on the computer under this condition ensures that it is really dead.
If you have a satellite or cable receiver, you are aware that you are supposed to unplug it and wait for up to 30 minutes, right? That's the same thing. Unplugging something does not remove all power - only all external power. Pressing the On button removes whatever is left.

TS3048 No bluetooth whatsoever on Macbook Pro 10.6.8, resetting PRAM and SMC does nothing. Help?
Bought a wireless Magic Mouse today, was real pumped to go home and use it. When I turned my computer on, there was no bluetooth whatsoever to connect to. I read the forums for solutions, tried resetting PRAM and SMC. Neither worked. Let me know what I can do.
If the HDD will boot your MBP externally but not when installed in the MBP, that usually indicates a bad connection.. Either the connecting plug is not seated properly, ot the connecting cable is loose or faulty. Open the MBP and check very carefully for those conditions. To repair or replace connecting cable is not an expensive repair, even at an Apple store.

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
Roque1. 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.
Triple-click anywhere in the line of text below on this page to select 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.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with "Model Identifier." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

We have had several (7-10 recently) macbook Pros start this issue. The screen will jump from regular to blue, the background image will go away and it will be replaced with a blue screen, the icons change size and the screen resolution changes. Someimtes the users name field on the login screen will fly in from off screen... run diagnostics (AppleJack, Disk Util) and reset PRAM and SMC and sometimes this helps but wanted to know if there was a definite reason for this or a better resolution to the problem?
Thanks all
Macbook Pros are all newer (some only a month old) Unibody models running Snow Leopard and LionAppleJack has been discontinued, so you should uninstall that.
I'm suspecting something in software across all machine or a security breach as the primary cause of your problems.
Wipe and install everything fresh, firmware update the router, change passwords, new software form original sources, etc.
This might assist.

Bluetooth not available even after resetting pram and smc!
Hi, my bluetooth on mbpro is not working now, i've tried resetting pram and smc but it is still the same ! could it be a hardware problem?
Try doing a Safe Boot and then reboot normally...

If you are still having Fan Issues... you could try another SMC...
Just a thought... -
Computer really noisy (fan I think?). Resetting PRAM and SMC does not work.
Hi,
so basically, as the title says, my computer is making a really loud noise as soon as I turn it on, I am presuming it is the fan.
Over a month ago, my computer started to constantly crash, and about two weeks ago I took it to a Genius Bar for a diagnosis. The problem was a hard drive failure, so I had it replaced and yesterday I brought it back home.
However, after the fix, the computer now runs fine, but there is a really loud noise from the computer.
I have tried resetting the PRAM and SMC like some other threads have suggested, and none of them have worked. I have tried restarting, shutting down the computer and everything suggested.
The computer has never made this noise in this manner before.
Before the fix, the only time it would be noisy like this is when I wake it from sleep, just left it there (on screen requiring username and password) and it sleeps again, and if I wake it from sleep, then it would be loud like this, but that is solved by just simply sleeping the computer again and waking it, and it will be all quiet again.
However, now, it makes this loud noise as soon as I turn the computer on, and as long as the computer is not shut down or asleep, it will make this noise.
Before the fix, my OS was 10.4.11, but the Genius Bar had installed 10.5.8 on this hard drive.
Is this a software problem or a hardware one?
Anyone got any suggestions or ideas how to fix this?
I have called the Apple store I visited for this fix already, they push me over to AppleCare and AppleCare pushes me back to Apple store and they tell me they cannot provide technical support over the phone and would need me to take the computer back to the Genius Bar.
I am just not happy about this. I live almost an hour away from the closest store and I have university to attend to as well.
So I am hoping this problem can be resolved without having to go back to the Genius Bar, although all methods I have read so far do not help.
Thanks,
From LelouchHi, well, the thing is, I am just worried that, while making other repairs, they might have damaged something unintentionally and probably do not know about it, which would not be documented.
My initial problem of a loud fan, after a hard drive replacement, was fixed, so I do not hear it anymore, but this wind-like noise is different. With the iMacs, I presume the fans are towards the top, which was where the loud fan noise came from, however, this wind-like noise seems to come from the bottom of the computer screen are, centre and right side (in the direction I face it), but not the left side.
I describe it as wind-like, but it sounds a bit like when the computer is on heavy demand and the computer loads, yet different as it is quieter and slightly different in pattern, and unlike the usual heavy demand noise which comes from the top, it comes from the bottom.
I actually installed a temperature widget after my last repair, just in case my fan was just simply tuned off and would not come on at all for the sake of fixing the loud noise it was making.
The temperatures read as follows:
HD: 31
CPU: 27
Ambient: 17
GPU: 36
GPU Diode: 46
GPU Heatsink: 36
HD Bay: 33
Optical Drive: 30
To my knowledge, these should be fine temperatures?
But the noise persists regardless. The noise can instantly be heard (providing that it is quiet enough) as soon as the computer starts up.
Thanks,

I'm sure this has been answered before but I can’t find it. I have a 2008 MacBook Pro running Lion. How do I Reset PRAM and Reset SMC
Thanks
MichaelBarry,
Thanks, Found answers to both questions. I'm new to the support forum, I usely just ask my son, but I decided to give him some rest from my stupid questions, that I can find the answers to with a little searching of the forums.

Resetting PRAM and SMC does not resolve crashes; what next?
Lion has been crashing (when going to sleep, when waking from hibernation, when closing Safari's last tab, when shutting down, among other, less common, scenarios) very often on my MacBook2,1.
What is the sequence of steps you would try to resolve, or at least debug, the problem? I have already reset the PRAM and the SMC. Imperically, the rate of crashes may have already lessened, but it still happens. What to try next?Here is the last gory message. I did nothing more perverse than boot the laptop, launch emacs to read a text file for a minute, exit emacs, then shutdown. It didn't. It crashed instead. This is the crash log when I rebooted.
Oh, and I was in the car. So I wasn't connected to anything of any sort.

This issue happened randomly. I was working away and the bluetooth just disappeared. The first time this happened, I reset the SMC and it solved the issue. Now, nothing seems to work including removing the bluetooth plist file. Any ideas on how to fix? Thanks.
To find out if it's system wide or user specific, try this...
Open System Preferences>Users & Groups, unlock the lock, click on the little plus icon, make a new admin account, log out & into the new account.
Does it work in the new account? -
anytime I get it to boot, it works for a day or two then goes back to the Question mark screen.
Hi! It could be HD issue. You should back up your data in the computer first when you can boot to normal desktop. boot to install disk to run disk utility - if it got error over there, you should bring the computer to repair centre to fix it. You also could try to erase with zero out and install again And see will that be fix the issue!

Macbook Pro Retina over 200F 5-10 fps in games (after SMC/PRAM Reset)
I have struggled with this for too long now.
I have read every single thread I can find about the issue and tried both complete reinstalled of Bootcamp, SMC reset, PRAM Reset, EFI updates, etc.
When I first got the Macbook, I could run our game development setup in around 60-80 fps.
I use the labtop for game development in Bootcamp (Windows 7 64)
Currently im not able to get more than 10 FPS. And it runs very bad - it runs in 30 fps the first second, the next its a 5, and then it goes up again.
Even though nothing happens on screen.
When i launch a game the GPU and CPU is over 200F in heat.
And thats with all the fans on constantly.
Im very worried here - Im travelling next week where I need this machine to be able to work.
What should I do? Is it broken? Should I get a new one, or will the same thing happen?
Thanks a lot in advance guys!I would strongly suggest you take it into Apple Store to get it looked at.
In the mean time I can only suggest changing power management to see if this fixes it for now:
You can change the way your computer hybernates from hybernatemode 3 to 0.
3 = RAM is powered on while sleeping, but RAM contents are also written to disk before sleeping. In the event of total power loss, the system enters hibernation mode automatically. The downside to this mode is that it is very slow. The upside is that it is very unlikely that you will lose any unsaved work should your mbp lose power.
0 = RAM powered on while sleeping, safe sleep disabled, and super-fast wake. The downside to this mode is that it does not save any of your work, should your mbp lose power, and you would have to remember to manually save before putting to sleep. The upside is that your computer would sleep & wake up in around 2 seconds.
Go to Terminal & type:
pmset -g | grep hibernatemode
That should give you a result of 3.
To change it to 0 type:
sudo pmset -a hibernatemode 0
It might ask you to enter your password.
Then delete the old sleepimage file:
cd /var/vm
sudo rm sleepimage
Just remember, saving will have to be done manually by you, -
I have a optical lead coming out of the headphone jack in to a dac that goes in to my amp (which has speakers connected) so i can listen to music. The Dac is powered by usb. Recently the sound stopped working. I called tech support and they suggested the resets (pram and smc) and i reinstalled lion and reinstalled itunes, deleted audio files, blah blah blah.
So now when the computer turns off, or indeed randomly sometimes, I have to uplug the usb cable and put it in a different port, it then works. If I then put it back in to the original port it still works. Totally baffled. Can anyone please help. i have 3 children who are getting very bored at the sight of my growling perplexed face and the sight of my back!I don't know why that happens, since I don't own products of this type... However, if the sole purpose of the USB connection is to provide power (not a data connection), can you connect it to something that just provides power, such as a USB power adapter (like the one that comes with iPhone)?
http://store.apple.com/us/product/MD810LL/A/apple-5w-usb-power-adaptor
Or, if it needs to be connected to a USB port, it might work properly if you get a self-powered USB hub and connect the USB cable to the DAC to the hub. The hub would act like a "buffer" between the DAC and iMac. It needs to be "self-powered" (comes with its own power supply). Here's one such USB hub
http://eshop.macsales.com/item/Newer%20Technology/USB2HB7PRO/
Do you have anything else connected to USB (other than standard keyboard and mouse)? If so, have you tried it with ONLY the DAC connected, to see if the problem recurs? USB devices can interfere with each other. -
External Display resolution problem after resetting PRAM
Gello, I've got Fujitsu-Siemens P19-2 monitor hooked up to my MbookPro and after resetting PRAM the correct display resolution disappeared from the "Displays" menu in System PReferences.
So did the refresh rate option...
What do I do?
I really need to change the refresh rate and the resolution, but the refresh rate button is grey and unclickable, and the resolution simply isn't there (I need 1280x1024).

Is it ok to have a PRAM and NVRAM reset two times a week?
No, it doesn't do any good unless you're having a problem that those procedures fix.
Edit: I've never reset PRAM or SMC/NVRAM on 4 out of 5 macs. -
Resetting PRAM/SMC to fix airdisk problems in Leopard?
Has anyone tried this after installing Leopard and are experiencing slow-down issues with Airdisk? I'm keeping my fingers crossed that it helps my woes - mainly with streaming divx movies from the airdisk. I reset the PRAM and SMC and so far so good, but I'm sure my luck will change (I hope not!).
