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 6 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 am trying to fix a friends macbook pro. When I turn it on the screen shows the apple and the spiral underneath it spinning like it should then when it stalls for .2 seconds it goes to a white screen then there is vertical purple lines in groups across the screen. So the screen is white/purple. Then it fades to just white and I cant do anything.
I hooked up my monitor with a DVI cable to see if it was the motherboard that was possibly bad but the monitor works just fine with the cable. I can use the computer with the laptop keyboard/mouse and it works just fine. The laptop screen just stays blank the whole time. I uploaded a vid to utube for it. If anybody has any ideas for me please help. I dont know if this is a monitor problem or the inverter or the motherboard, possibly some other piece of hardware?

I 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 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.
View 3 Replies View RelatedI 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..
I have a MBP 13inch from 2011
recently i zapped my Pram becuase i was having trouble with a external screen but when I turned it on again the screen when to the grey screen with the apple logo and spinning gear but after 2 hours of wating the screen is still the same. What can i do to get back onto my mac?

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.
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 tried two different brands of blank CDR in my drive and both times, they fail to mount and in Disk Utility, show up as Sony DVDs (neither of them is a Sony or a DVD), but not writable. I have no problem with media that already has content. I've tried resetting PRAM, but nothing else yet.

I tried the SMC & PRAM reset. Now, there is a delay in my keyboard and mouse. For example as I am writing this, as I type, I am observing a ~1/4 sec delay between me pressing a key and the GUI registering it. The same with the mouse. I can click-and-hold over say File and move it up and down over subsequent menu items and it the GUI doesn't highlight the menu item unless I slow down the movement.

Updated to OS X Mavericks last week. Ever since, it has been experiencing boot problems.
- If I restart my Macbook Pro (2011 13", lowest model), it will sit at the grey screen with apple logo and spinning grey wheel forever. I notice that my HDD is NOT running (no clicking / writing sounds)
- If I restart with a PRAM reset or holding down option to select Macintosh HD boot, the hard drive starts to run (I can hear it) and it boots successfully... it takes 5+ minutes to boot up. The grey screen with apple logo is presented on my screen for about 4 minutes, then the login screen shows up but I cannot move my mouse or select a login user for 30 seconds. After this, I can log in succesfully.
-Also, switching users takes 1+ minutes. Clicking "switch user" freezes my screen.

Recently 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.
The only things about my MacBook Air that have changed in that time period are:
- I installed OS Yosemite
- I installed and ran Sophos Anti-Virus
(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.)

Today 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?

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 understand the steps needed, but how many times should I reset the PRAM and how many times should I here the startup sound (in total) before releasing the buttons?
View 3 Replies View RelatedI attempted to reset the PRAM on my macpro running snow leopard this morning, by rebooting and holding cmd-option-p-r until the apple logo appeared, at which point I released and then machine then rebooted a second time. I went back to the computer about an hour later and it was stuck on the apple logo screen, with no sounds coming from the CPU. I did a hard reboot by holding down the power key and it started up fine. I've never reset the pram before and so I didn't know what I should expect as far as the process being successful, but after an hour stuck on the apple logo I figured it got stuck on something.

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.

So I contacted Apple this morning regarding the LCD Backlight Bleed on my iMac (24", early 2008, 2.8 ghz) They made me reset the PRAM, which I figured wouldn't work, and the issue is still there.
They say it'll have to go in for servicing, and I live nowhere near an Apple Store, so they gave me the location of the nearest London Drugs. Am I going to get the same quality of service as I would from an Apple Store? And what is the exact process that they use, do they just replace it with a new LCD?Also, he said that it will be covered under Applecare unless it is ruled as accidental damage, he said that much of the time, the issue is caused by pressure on the back of the case, and that if that was the case, it wouldn't be covered.I can't really see how this would cause it, and I haven't ever put any pressure or anything on the back, but i did buy the iMac used, what are the chances of this being ruled accidental damage?I have the bleed in all four corners of the screen, if that makes any difference.
My MacBook Pro will not start. It chimes and the gray progress bar starts and then the computer shuts off. I am able to start it holding the Command +R keys and access Disk Utility. That is where it says my S.M.A.R.T. drive is "failing". I have a backup from Time Machine from a week ago. I am concerned the computer is going to die. What should I do and is my computer going to die?.

I have an old Titainium powerbook which I was going to give to a friend to access the internet whilst he is at work, only problem is that it does not seem to want to start. If I press the start button I get a distorted sounding start-up noise then nothing (not even a grey screen) The caps lock light lights up but nothing else.
If I press the re-set button on the back then the power button it starts up fine and works without any problem other than having to re-set the clock and date. I thought it might be a problem with the pram battery so I have just changed this for a new one, but its still the same. The main battery is dead but thats OK as it will be used on the mains adaptor.
Unfortunately I bumped the switch on the power strip that my Mac Mini (1.42ghz G4, OS X 10.3) is plugged into while it was running. Now it won't boot up. All I get is the gray screen with the gray apple logo and the spinning wheel but no OSX.

In the brief reviews I've seen, the Macbook Air is credited with great viewing angles. I just bought the 11" base model. While the horizontal viewing angles are great, the vertical ones are modest. It's definitely decent if you look at the screen straight on or from above, but it fades quickly and inverts when you look at it from below level even to a modest degree. I have the 2008 unibody aluminum Macbook; the one that was quickly renamed the Macbook Pro and provided with a better screen and an SD slot. To me, the viewing angles are definitely improved but I don't have a Macbook Pro to compare it with, or the previous generation Air.
