I have macbook pro 2011 Early, running Mac OS 10.9.4
After i upgraded my SSD and boot to restore Mac OS 10.9.4, i have firmware password. But i can't remember. How can i reset firmware password?
I forgot the Firmware Password, and want to reset it. How can I do it? No DVD included when I bought it. All the startup keys, like C, N, T, D, CMD+s, CMD+Option+p+r, CMD +v, Option, and Shift, does NOT work. To add or remove DIMMs does not work.

I recently bought a cheap eMac which used to be a networked terminal at a university. I am hoping to do a clean reinstallation of Tiger but the computer seems to be tightly locked down. I am able to log in because I have a local username and password, but I do not have administrator privileges. There is also a firmware password so I am unable to boot from the installation DVD. When I insert the Tiger DVD, I am unable to restart the computer and start the installation because it requires administrator authentication. Is there any way to disable the firmware password and the admin password so I can basically remove everything and start with a fresh copy of Tiger?

I tried the method of removing some ram and yes i did it correctly plenty of times and got nothing.
then i also opened the whole intire computer and disconnected the battery and also got nothing.
also right now the system has no O/S so i am not sure what to do from here. I cant use any boot commands or anything.
I just picked up an old eMac today that I'm trying to get it working. The problem is the open firmware password is set, and I have no idea what it is. If the open firmware password is set, it prevents you from doing anything without it including booting from a CD and zapping the PRAM. I changed the ram, removed the internal battery and hit the PMU reset button expecting this to clear the password, but it didn't work. Removing the internal battery did reset the system clock to 1/1/1904, but didn't change anything else.
Also aside from the practical question about resetting the password, I'm suddenly left wondering where the system stores the open firmware password. If it isn't stored on the hard drive, and it doesn't depend on the internal battery, then how is it saved? Just for clarification I have no idea who the original owner was or where it came from. So there is no chance of just finding the correct password.
Is it ok to have a PRAM and NVRAM reset two times a week?

I have a February 2008 MBP and am having issues with keeping it asleep. I currently have it set up as a desktop connected to an external monitor, keyboard and Magic Mouse (along with a variety of other peripherals) and I've recently noticed this issue. I'm running 10.6.1, I have tried everything from resetting the PRAM, SMC and repairing disk permissions to even installing a clean copy of Snow Leopard and restoring from Time Machine backup.
For power management, I have it set to never sleep, since I manually set it to sleep and don't want it sleeping on me when in use. I also have Wake on LAN activity disabled. Yet when I set it to sleep, at approximately noon the next day it wakes up by itself. I've even turned off the Magic Mouse to make sure it wasn't being moved by vibration and waking up the Mac. I'm completely stumped!
For troubleshooting purposes, I've installed a clean copy of SL without restoring TM backup to see if it's a program that's causing this issue or if it's a problem with a peripheral. I've yet to check back on it as I'm at work, but I'm hoping it's just software related. I'm at a loss as to what to do.
recently had a small USB issue, so I reset my PRAM which fixed it.Now every time I boot the PRAM will reset itself. This particularly annoying because:1) It takes longer to boot as it restarts again and again (sometimes 3-4 times).2) I have the boot volume set to 0 and when the PRAM is reset it will go back to default which isn't fun [and it loud].
3) I have verbose mode on and a PRAM reset removes that as well, so I need to do the 2-finger combo [which on the bluetooth keyboard doesn't work half the time].I can't seem to fix it. I've done all the usual things (ie: manual PRAM reset with 4-finger combo, SMC reset, reseating hardware, disconnection hardware) and I've also gone ahead and installed OS X on a new volume for testing. Nothing is working and this getting a little frustrating.I try not to restart my computer, but recently I've needed to it a couple times. Apple Support doesn't know what to do and they're reluctant to send a on-site tech because they're not sure what the issue is. They want me to take my computer to the Apple Store, but (1) I don't have a car, (2) it's windy and snowing like crazy outside so there is no way I'm walking a mile to the Apple Store carrying the Mac Pro by hand, and (3) even if it was sunny outside my computer weighs a lot.Anyone know what's going on here? The computer passes all hardware tests and disk scans reveal no bad sectors.
I had my 2008 Mac Pro unpugged for a few days. When I turned it back on the USB ports weren't functioning. I can't reset the PRAM as my keyboard is not working.

What does everyone mean when they say this?
What does it do?
Basically, all the general information about it.. I've been reading people's problems and I see this all the time, and I'm totally confused on what it.
Also, what is PRAM? What does resetting it do?
If I need to reset the system on my macbook pro 17", do I use the Firmware Restoration CD or is there something else?

I have already covered these steps:1. I have tried a safe boot. 2. I have tried to reset the NVRAM and the PRAM.3. I have tried to reinstall OSX from the Install Disk.4. I have tried to repair the HD and tried to repair permissions using the Disk Utility. he issue started out as the flashing Apple/Question Mark Folder/"No" sign. I attempted to follow the steps on the Mac Support Forums (ones listed above) and the issue developed into the picture shown.

I have inadvertently left my 2011 MBP running with a processor intensive music app running. The battery ran out before i realised.. When i attached the power lead to charge it, the computer automatically restarted without even pressing the power button. The computer had not entered safe sleep mode, presumably because my music software was still running.Â
Since then the computer will not ever enter safe sleep when the power runs down. The battery just cuts out each time when it drops to less than 5%, it does not run out at 0% like it usually does. if it is the logic board battery because i have had this issue a couple of times before but it rectified itself after a few days. I have checked that safe sleep is enabled which it is, but the computer just cuts out before safe sleep kicks in.

I have a 2006 Mac Pro and recently my firewire ports stopped working (front and back). I did a little searching around found a suggestion to try resetting the Mac's PRAM and NVRAM by holding the Cmd-Option-P-R keys down while booting. I have tried this numerous times and it doesn't seem to do anything (i.e. the Mac just loads OS X and doesn't re-boot like the instructions say). I'm using a MS Wireless Comfort Keyboard for Mac. Can you reset using a wireless keyboard?
Since I wasn't making any progress with that, I was toying with bringing in the Mac to a genius bar. Never having used the genius bar before - how does it work? Do I bring the computer in and leave it with them? Do they work on it while I'm there? I don't have an extended warranty so do they charge time and materials? I'm wondering if that might get awfully expensive and if I ought to just buy a PCI-X firewire card instead.
Any suggestions?
Man, what's up with this? Shut down on my early 2008 MacPro (10.5.7) takes forever! I've tried resetting the PRAM and it did this with earlier versions of Leopard as well. I've reinstalled the OS twice, changed hard drives and wish I could fix this.
View 15 Replies View RelatedRecently my MacBook Air has failed to wake from sleep mode. The Apple illuminates on the back of the screen casing, but neither the screen nor hard drive actually wakes up. The only way I'm able to use the computer is by forcing a PRAM reset on restart (command-option-P-R). I've had to do this several times in the last two weeks. Â
The only things about my MacBook Air that have changed in that time period are:Â
- I installed OS Yosemite
- I installed and ran Sophos Anti-VirusÂ
(The latter was installed to counteract a problem that I was having with my email address having been spoofed and sending spam. Sophos found two bits of malware in email data files and "cleaned" them up.) Â

I've recently purchased a broken 1GHz Alum PowerBook G4 12", and the display isn't working. I have a total of two 12" PowerBook displays, and I've tested both. They've worked perfectly fine. Then I've tried reseting the PMU and PRAM, no luck, but they've attempted to work. Tried the Mini-DVI to VGA adapter with my display, still no luck. The keyboard, optical drive, and hard drive works as if it was booting, and there was always a clear chime, even when I've reset the PRAM and PMU (the beep sound when PRAM also attempted). I've inserted a Leopard install disk, and it sounded like it was working perfectly fine. Hopefully it's not a motherboard issue
View 3 Replies View RelatedToday I noticed that my mid 2010 MBP is not automatically sleeping. I ran Apple's extended hardware test, along with TechTools Pro 5 from AppleCare disk. Both passed. Reset the SMC and PRAM. I'm still not able to auto sleep. Is there a way to see what exactly is causing my computer to not automatically sleep? Console messages or something?
View 7 Replies View RelatedI have a mid-2011 iMac (with Mavericks OS), and am doing a clean install before giving my computer to a relative. I performed a secure erase of my entire harddrive (using disk utility), reset the NVRAM / PRAM (but it only chimes once even after I tried several times), and now I get the grey screen even when I try to boot from CD, safe boot, or any other commands. I can't even get back into the disk utility.
On a side note, I have the install DVD in the DVD drive and I can't get that out.

I recently purchased a 13" 2.26 stock macbook. It's perfect, screen is good (no scrolling issues or purple blues) with no dead pixels, no slanted keys, and no scratches.
I updated the firmware that addresses the SATA 1.5 issue. After the update, I reset PRAM. I held down the buttons till I heard the second or third startup bong.
Here is where it gets funny.
Now, when I reboot or start up my computer, the start up noise is loud. Even with headphones plugged in and also the volume turned to its lowest setting (even with volume turned off). Eventually, to control the startup noise, I had to install the startupsound program in my system prefs as mentioned on other threads and that has seemed to control the startup sound.
I was wondering, if by resetting the PRAM if I have harmed my computer in any way. Should I be worried about deeper issues with my computer since the startup sound was not previously being affected by reducing the volume to zero with headphones plugged in?
I have tried SMC and PRAM resets, and the issue has not been resolved. My magsafe is lit up with a bright green led. Battery status is "Not Charging." When I unplug the magsafe, the system immediately shuts down. Battery is brand new with only 2 cycles. While I can use the laptop with power connected, this is an issue that needs to be corrected asap, as I use this computer for performances consistently and if the power cord gets removed, I'm not in a good place.

I have a strange boot issue having (tried) to install EFI 2.7 update. When I restart the laptop, it 'chimes', displays a grey screen, then chimes, displays a grey screen, forever. I hit the bower (off) button for 5 secs or thereabouts, and restart, same thing. I do this 4 times and finally it reboots. But the EFI update still appears as needing to be installed (software update tells me it is not installed). Update history shows however that it IS installed. I can go through this process any number of times. I now have Software Update history showing quite a few installs opf the EFI 2.7 update. If I just do a restart without installing, I also go through the same fail to restart / fail to start / ... / eventually restart sequence.
So it seems now that the laptop will only start after 4 failed restarts and finally it starts. After starting it all appears to be perfectly fine. Nothing strange in the console logs that I can see. The failed reboots don't seem to register in the console logs - I suspect that the failure to restart is pretty early on in the boot sequence, well before it tries to load any semblance of the OSX kernel. It is almost as if it is trying to boot from someplace other than the disk ... until eventually it gives up and tries the disk. (I have tried booting with and without network cable - no difference) I don't know enough about mac bootup sequences to know if there is some config/setting that is screwed up causing this odd behaviour.

My macbook pro won't boot past the grey screen, I've tried reseting PRam, running fsck from single user etc to no avail. All signs would point towards a hard disk failure, but the curious thing is that it sometimes mounts in disk utility when booting from the install CD, so theres a little life left in it yet! I have fairly recent backups of most of my files, but there are a couple I've been working on in the past few days that won't be backed up. So my question is this - is it possible to copy files from my mac HD onto a external drive through the terminal/disk utility while booting from the CD.

View 1 Replies View RelatedI am running Mac OS Lion (10.7.3) on a 8-core Mac Pro. As I turned on my mac this morning, I found out that I was unable to use my wireless mouse, and also that I couldn't open my bluetooth settings. Apparently, the entire module disappeared from the System Preferences, and when I went to one of the articles on here, I saw that I'm supposed to reset my PRAM and SMC in order to make my bluetooth work again. The problem is, that I don't know what PRAM or SMC are, nor do I know how to reset them.

I have a 17" Powerbook G4 1.5 GHZ. I lost all sound from one moment to the next. System preferences says Audio output Headphones however no sound from Headphones either. I tried to reset my PRAM, however when I hold down "Option" "Command" "r" and "P" the computer won't restart. The hard drive seems to be stuck at this point and won't go any further. I went to the Apple store and the Genius lost patience and said we should send it out. (I'd rather not)
I have also reset the PMU
Everything else works fine.
I've looked at several other threads and post. Everyone with a sound problem seems to be able to get it resolved with a PRAM reset. However I find nothing on my the problem of not being able to reset..
