Imac 24" stuck in loop after log in, upgrade SL
Hi Folks,
I installed SL yesterday evening successfully , and this morning when starting up, my imac freezes just after log in, it seems to be stuck in a loop and does not go on...:(
I tried re changing user password,verify&repair, Pram Reset,i reinstalled SL, but it nothing helps, still stuck in tha loop
anybody has an idea?
If it freezes after just logging into a user account, chances are good that something in that account's home folder is the culprit. The most likely suspect is an incompatible login item in System Preferences > Accounts > Login Items. A Safe Boot disables (among other things) login items, so if doing that avoids the freeze, open the preference & check out those items for anything unusual or not from Apple that may need to be updated or removed.
Tip: if you hover the pointer over the name of an item in that list for a few seconds, its path will pop up. This usually gives you a clue about where it came from even if the name itself does not.

Random iPhone crashes and reboot loop after iOS 7 upgrade
Hi all
Since I upgraded my iPhone to iOS 7, I suffer from random crashes/resets, where my iPhone reboots and enters a reboot loop (Apple logo, black screen, reboot, Apple logo, black screen, reboot, etc) that I can only exit by restoring the device (resetting doesn't help).
Some more information
a) The device: iPhone 4, 32 GB, has never been jailbroken, and has never shown any similar issues before.
b) The crashes/reboots: I haven't been able yet to find a pattern when and why they happen. I had reboots when searching for an app, when pluging in the wall charger, when entering the access code, and even when doing nothing at all (iPhone in my pocket). The only constant is the reboot loop after the crash.
c) What I tried so far: I restored the device several times, using normal restore (with the iTunes logo) and DFU mode (black screen). After that, I recovered from a recent backup (takes some hours), and everything is ok again - for some hours, until the next crash and reboot loop. I also set up the device as a new phone, and there it seems stable, so I exclude a hardware issue. I tried quite a few of the advices that I found when googling for reboot loops: reset all settings (this led to an another immediate crash and reboot loop), disable app background refresh, etc.
I've been using this device for my daily business. With the current instability (and the couple of hours it takes to bring it back to life again), it became more or less useless. I wish I could downgrade again (I know that I can't). My assumption is that either iOS 7, or some incompatible app or some corrupt setting is causing this situation. But I don't know how to proceed to isolate and eliminate the issue. I really would like to avoid setting up everything from scratch again.
Any advice is greatly appreciated!All,
First of all, sorry for my half-finished post above. While typing, I was interrupted, and by reflex I hit CMD-S. Unfortunately, the stupid interface of Apple's support website interpreted that as a submit command. I tried to complete my text with the update function, but when finally hitting the submit button, I got an error message, and all my updated text was gone... No way to bring it back, and also no way to delete the half-baked posting. Quite frustrating.
Now, to complete what I started above:
In my case, the problem definitely had something to do with the springboard process (an iOS system 'app' that manages the iOS homescreens) and the watchdog process (another iOS system 'app' that monitors certain things on your phone and that can initiate a restart when it thinks the phone is frozen). In the folder '/Users/<your account>/Library/Logs/CrashReporter/MobileDevice/<your phone>' I could see what caused my crashes; they were all 'stack+SpringBoard' and the reason in these crash log files was 'Watchdog timeout'.
The following two forum posts helped me:
https://discussions.apple.com/thread/1676330?start=30&tstart=0
https://discussions.apple.com/message/20794982#20794982
I'm quite sure that my issues had to do with the 'application map' that is mentioned in the above posts. So far, Ive been thinking that it was just too large (as in the case of Andi1996 [second link above]), but jmbladen's observation seems not to support this. So, the absolute number might not the source of the problem, but I still assume that something went wrong with my application map during the upgrade from iOS6 to iOS7. I remember having stability problems before, as soon as all my 10 home screens were full of apps and newly downloaded apps would generate additional pages (only visible via iTunes). Considering that there are some fundamental changes to how we can organize apps within folders in iOS 7, it can well be that the springboard process just wasn't able to cope with my application map correctly within the 120 seconds before the watchdog process restarts the phone. My massive cleanup action must have fixed this somehow.
@jmbladen: I'm only using iCloud for the 'find my phone' functionality, so all the backup & recovery was done via iTunes from my local harddisk. And there was no temporal pattern for my crashes before. You might suffer from the same symptoms, but probably not because of the same cause.
My advice for anyone affected by random crashes and a reboot loop is to check out the directory with the CrashReporter logs mentioned above to find out what app or process causes the crash. If it's the springboard and watchdog problem, then you should try to clean up your home screens (from iTunes). Maybe the absolute number of apps is not that important, but make sure that you reduce the number of screens. And then sync and backup before you start using the phone again. In my case it helped.
Hope this helps someone else too.
P.S. Once you know the right keywords to search for, you find forum postings back to 2008 / iOS 2 describing exactly the same problem. This reboot loop is a very nasty issue, and it is hard to understand that Apple still hasn't been able to address this, or at least provide some better help on how to get out of it again. -
HT201263 iPhone 4 stuck in loop after downloading iOS 6.0.1
I downloaded the newest version of iOS 6 to my 5 month old iPhone 4. After about an hour I noticed that the phone was in a perpetual power up/power down loop. I assumed it was part of the downloading process (although it seemed weird) so I left it for another hour. The phone never came out of the loop, and was not recognizable in iTunes or to my computer. After about 3 hours I was finally able to get the phone off by holding down the power button.
The loop that I described consists of the phone powering up to the apple logo, and powering down, repeating every 5 seconds.
I was finally able to get my computer to recognize the phone by holding down the home button while I connected it to the USB.
In iTunes, I restored the phone (1.5 hour process.) Following the restore, the phone hasn't changed, still stuck in the loop.
I have tried everything I know to do.
Any ideas?
The phone is not jailbroke. When the guys at AT&T plugged it up to their computer, the screen turned bright blue. They said the blue screen normally pops up with water damage? The phone hasn't had any damage.Thanks for the reply.
Yes i tried in my pc and disabled both and in my MacBookPro too, still no luck. -
Iphoto 11 stuck in loop after upgrade
Have recently upgraded to iPhoto 11 through the app store from the version that came with my MacBook Pro (v8 or 9). iPhoto 11 is getting stuck in a loop with the gray screen and rotating busy icon in the middle. I have tried a number of online advice actions but all seem to not work (permissions, DIV X, deleting some of the files in the package, etc).
Surly there must be an official apple fix for this.iPhoto 11 is an application that runs on the Mac. You posted your questioning the iPhoto for iOS forum. Perhaps if you posted your question in the life > iPhoto forum you'll get more responses.

Stuck in Restore Loop after 3.1 Upgrade
Can anybody help? My iPhone is now stuck in a constant restore loop and I cannot downgrade to 3.0.1. My iPhone is effectively now a brick.
This issue has really got me seething at Apple. Do they not test these things?Just tried to update to 3.1, should have read the forum first. Had I seen the problems everyones been having I never would have tried it. When the update was finishing the iphone disconnected from itunes then the screen showed that I need to connect iphone to itunes. Tried reconnecting a million times, rebooted my computer, and tried to reset my iphone. It won't turn off or reset. When I was finally able to get it connected to itunes again, it says it must be restored. I freaked out, because my pictures didn't get backed up (even though I had them checked) and I can't afford to lose them, or any of my contacts and calendar events that also didn't manage to get backed up. I finally gave in and decided to restore, and it won't even try to restore. My phone worked perfectly well before this update. To top everything off I'm going out of town tomorrow and now have no phone, no ipod, and no internet. Any suggestions would be appreciated, the only option I have for now is to go to AT&T tomorrow and rant for them to pull the info off my phone if possible and restore it for me. HELP!

After I tryed to update to the new iTunes, I needed to update my iPod when I did this there was some error and it told me restore to factory settings. My screen on the iPod went from the color screen to a black and white screen after the update as well. I have tryed the changing the drive letter and this did not help. When I disconnect my ipod it tells me I need to connect to a computer. I would really like to be able to use my iPod again can anyone help me with this problem. I even tryed using the old updater to see if I can put on the old iPod software it didn't work. I tryed going back to the old version of iTunes this didn't work. I tryed the 5 Rs a few times and they have not worked yet.
Please help me.I now have the same problem with my iPhone 4s. Updated, phone went into the endless loop cycle now it's a brick. I have an appoinment at the genius bar tomorrow, so if they have a solution I'll post after the assessment, but I doubt it probably completely stuffed the phone. Hopefully someone here will figure it out before then and I won't have to go.............really ****** off at the moment though.

New 21" iMac with SSD; panic loop after updating to 10.8.3

I suspect it has to do with some graphics drivers. Suggestions? Thanks.Your system is crashing when it comes on

My recommendation would be to update or uninstall the app that is using it. Remember OS X does not have to be running the app in order for the KP to occur, it just needs to "see" it. If you choose to uninstall locate and follow the developers instructions for doing so. -

Ipod touch 8GB stuck in loop after resetting ipod during update
I reset my ipod touch 4th generation while it was going through an update because it stoped during the update and would not continue and i couldnt get out of the update screen. after doing so the ipod goes to the start up screen and does either of three things. 1. turns on, goes to boot up screen with apple logo and then goes to a screen with colors varying in blue. 2. ipod stays in a continued reset where the apple logo appears as though its turning on and after about a minute or two then flashes starts again. or 3 starts up and stays on the boot up screen and stays there. i have tried connecting to my computer and to itunes with no avail. any help would be appreciated

Few days ago while watching a movie, I suddenly lost color on iMac.
At first I thought something's maybe wrong with ATI Radeon HD 2600 PRO graphic card inside it, but then such color loss didn't happen when using Lion, before upgrading to Mountain Lion.
I noticed that on July 25 (when I upgraded to ML), a new ColorSync profile is created, found it inside System Preferences, Display, Color.
The old profile worked fine, obviously this upgrade to ML created some sort of corruption (don't know how to name it) in colors. Maybe an OS X update could correct this issue, but I'm not sure.
Is the problem in graphic card? Maybe the card should be replaced.
Any experiences?Permissions Repair:
Go to applications then to the "other" folder then go to disk utility, on the left hand side you will see a white box. Select the second option, usually called "mac HD" with that selected click on "repair permissions" in the center towards the bottom of the screen. Wait for it to complete, then see if this fixes the issue.
PRAM Reset:
1- Ensure the machine is powered off.
2- Locate the following keys on your keyboard in preparation for Step 4:
‘command’ – ‘option’ – ‘P’ – ‘R’
3- Press the ‘power on’ button.
4- Immediately – and before the grey screen appears – hold down ‘command-option-P-R’ all together.
5- Keep them held down until you’ve heard the start-up chime twice. After you release them you should hear it again, and hopefully your Mac will boot up normally -
Apple TV 2 Reboot Loop After iOS 5 upgrade.
OK, here's the deal... I upgraded to iOS 5 on my Apple TV 2 and now all it does is reboot. It never makes it to the menu, just starts up, shows busy icon and after a minute reboots again. Have tried restarting with menu + down and unplugging overnight and plugging back in. I do not have a Windows of Mac Machine (ie no iTunes). How can I resolve this issue so I can start enjoying my Apple TV 2 again?
Thanks for the answer but I had already read that when I researched before posting a question. I can buy the cable but I'm not going to buy an operating system just so I can install iTunes which is what the instructions you linked to said to do. I was looking for a solution either via remote control commands to the AppleTV device or a solution of plugging in the AppleTV to Ubuntu to cause the reboots to stop. I guess since I'm not getting any other replies, it's just not possible which makes for a bummed out Apple Customer. The only reason I bought the AppleTV over the Roku was because I already had an iPod Touch to connect with it and I thought they had better quality control. I guess I made the wrong choice. Thanks for trying to help anyway.

M300 keep getting stuck at startup after running Toshiba Upgrade Asst
Hi,
I've just bought a copy of Windows 7. I ran the Windows 7 Upgrade Advisor and it recommends me to visit Toshiba page, where I found the link to download Toshiba Upgrade Assistant to prepare my Satellite M300 to upgrade to Windows 7. I managed to download all the required software. Everything was running smoothly up to the part where the Assistant is installing some components and restarted my laptop. The OS went through the usual booting up procedure and there was this "Please wait..." screen just before the login screen, and that screen just seems to run forever. I have tried letting it run for more than a few hours, but the Vista screen was still there, minus the "Please wait" wording.
I tried booting from safe mode and was able to get into desktop. I was able to run finish the Toshiba Upgrade Assistant from safe mode, although I notice that there weren't any components that were required to install. The ethernet controller was strangely missing. Unfortunately I can't install Windows 7 in safe mode.
Is there any solution other than bringing it down for to the customer service centre?As far as I know Portege M300 is not covered with this Win7 upgrade program.
Am I right about that? -
My late 2009 27" iMac gets stuck on the grey Apple logo when booting up. It boots correctly when in safe mode. I have tried erasing the HD and re-installing from a USB installer. It says the install is complete, but after restarting it gets stuck on the Apple logo again. This could possibly be an HD failure, but then why does Safe Mode still work and the USB install not work? Any ideas?
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.
Don't be put off merely by the seeming complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
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 behest 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.

Stuck in Restart Loop after Software Update
I recently ran the update to 10.5.3 a few days ago, and thankfully, it's been working great... until today, when I installed two seemingly innocuous updates via Software Update: one for the latest version of Quicktime and another for Apple Brother Print Drivers 1.1. After restarting, everything fell apart. Several of my start-up apps unexpectedly quit after login, and other apps either failed to launch when I tried opening them, or they simply got stuck in an endless loop of bouncing in the dock. I couldn't even force-quit them because they weren't responding at all. Thinking this strange behavior to be symptoms of some permissions issue, I popped in the Leopard installation CD and ran a permissions repair. It fixed several cryptic problems, one for something to do with Java and another for the cups folder, which I assume has some relation to the printer driver update. I then tried selecting my start-up disk and restarting, but the problem only got worse. Now my iMac is stuck in a restart loop. I tried booting in safe mode, but that hasn't worked. If worse comes to worst, I'll have to revert to a Time Machine backup, or else run an Archive & Install, but I'm trying to avoid that. Any suggestions? I'm also curious to know if these two updates had any relevance to these problems, and if so, what the cause may be. I'm thinking the printer driver is to blame, but then again that's only a stab in the dark. Any help would be appreciated. Thanks!
Thanks for the suggestions. I tried a Safe Boot again but unfortunately that didn't work, so I had to go ahead and do an Archive & Install. Now everything is up and running; however, I'm going to stay away from that print driver until I figure out exactly what went wrong. I did a little research and saw it listed on MacUpdate.com, where it was posted along with an interesting note: apparently, the update can only be applied if there is already a Brother print driver installed (in this case there was), and in addition to that, the printer must either be connected (and I assume on for the computer to know it's connected in the first place) or have an active print queue for the update to even be listed in Software Update. Strangely enough, neither of these conditions held true when I saw it in Software Update... so I think that might have been the cause, but I can't be sure. I was wondering if anyone else has installed this update successfully, and if so, what they did?
Thanks again for the suggestions. -
New iMac is stuck on grey apple screen after restart from Migration Assistant
New iMac is stuck on grey apple screen after startup. It is a 3.4GHz Quad-core Intel Core i5 running OS 10.9.4. The problem occurred after a migration from my older 2009 iMac which is running Snow Leopard 10.6.6. When the restart occurred from Migration Assistant, the new computer will not boot up to the login screen. Disk utility did not solve problem. Followed instructions for a soft reinstall of Mavericks but that also did not solve problem. Any suggestions?
Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
