Startup Problem Continual Chime Loop

Last night I tried upgrading my os but the install froze (I was just booting from the install disk). I had to do a hard restart but ever since then all I get is a continual restart loop.
The machine restarts, I hear the chime then the DVD spins up. Shortly after there's the restart chime again and I'm stuck in this continual loop. I've tried zapping the PRAM, Power management etc but nothing. I can't eject the DVD, or start in single user mode or anything. Whatever I try, after a few seconds the machine restarts with the chime again.
So frustrating as the machine was working perfectly beforehand. Now I can do nothing. I've serached the web to no avail, so this is my last hope of getting the PowerBook back!

OK, upgrade was from 10.4.11 to 10.5. The MBP restarted on the install disk then crashed before the install options came up.
When I restarted all I got were a series of startup chimes spaced a few seconds apart. I cant get anything from the keyboard. I've tried holding the trackpad button down and nothing happens. I've tried safe mode and nothing and I've tried holding down the 'c' key and again nothing.
I've also tried starting in target disk mode, but again nothing. Whatever key or combination of keys I press all I see is the sleep light on the base of the MBP this flashes, the DVD whirrs and then the machine restarts. And this happens over and over...
There are no responses from keyboard presses at all. I'm not sure that even zapping the PRAM has any effect as I can't tell the difference between that and the successive startups I'm getting.

Refurb C2D Mini occasionally gets into startup chime loop

I'm supporting a pre-2009 1.83GHz Core2Duo Apple refurb Mini that about once a week goes into a continuous loop thusly:
Press power button, Mini gets to startup chime, then it waits a few seconds and does the startup chime again. It repeats this ad infinitum and never gets past the startup chiming. Only way to stop this is to force a power off. At that point, it will generally startup OK.
There are no diagnostic beeps or flashes on front light. Hard Drive passes all DiskUtility tests. And the Mini works fine except when this startup problem occurs. The Mini is connected to a good UPS, so I'm ruling out bad mains power as the source of the problem.
Problem is so sporadic, that I'm concerned that my local independent Apple dealer won't be able to diagnose it. This dealer also has a reputation for keeping Macs for a month or so while it waits for parts. So my preference would be to deal with AppleCare directly over the phone and via mail-in. The Mini is within the one-year warranty period, but outside the 90-days of free phone support. I'm willing to buy AppleCare to expedite the solution of this problem. But even then, I'm worried that the problem is flakey enough that Apple is going to pass on it. I'm not within reasonable range of a real Apple Store, so all interaction with Apple will have to be over the phone and via delivery services.
What are the chances that Apple would know that this Mini was returned and refurbed for having precisely this issue with its original owner?
I'm open to advice. Thanks.

Update.
This has happened two more times, including just now.
If the Mini is forced off by holding down the power button, it then is able to be started normally after just a pro-forma 1 minute wait.
The startup chime is about half the duration of a normal startup chime. And there is about 2 seconds between each chime during the looping.
As an additional update, I found out by talking to AppleCare that mail-in service is not available for Minis, like it is for Apple notebooks. So purchasing AppleCare would not relieve me of having to deal with my local Apple authorized service provider -- who is not likely to have the patience to experience this sporadic problem.

After the latest updat to Mavericks 10.9.3, my imac continues to loop back to the login screen...Suggestions??? THANK YOU VERY MUCH!

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.
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.

My Mac G4 came unplugged while running and now when I start it up all I get is a continuous reboot loop.

While sliding my Mac G4 tower out from under the desk it came unplugged. It was running at the time. After plugging it back in all I get is a continuous reboot loop. I have tried the Shift and the Command Option P R boots to no avail. What am I missing here? I have had no problems in the past with this system. I am running Panther.

Are you using an Apple keyboard or something else. It is rather common for non-Apple boards, especially those pulled from a PC, to not respond to the traditional Apple startup key command combos.
Take the computer off wall power again then press and hold the power button for about 20 seconds. Then restore power and try a normal start. That worked for me when I had a similar failure to start with my G4 MDD.
If you have never replaced the internal backup battery ("PRAM" battery) it is, by, now surely extremely dead and it could not preserve the needed start parameters when power was unexpectedly cut. If you get the computer going, consider installing a new PRAM battery so you won't replay today's issues. tomorrow. The batteries are cheap and replacing one is a three-minute at-home job:

Startup problem with Lion OS 10.7.3

Just recently, I've been experiencing a startup problem with Lion. I don't usually have any issues running my Mac, so I'm at a loss why this is happening now.
I have an Intel Mac Pro running 10.7.3. I usually leaving my Mac running all the time and only restart when the need arises. In addition to being my main computer, this mac alsocontrols a MacMini that serves as a music server thru screen sharing.
This past weekend, I restarted my Mac and could not get past the grey screen. The mac chimes, the apple logo appears with the spinning gear, the blue screen briefly appears, but instead of progressing to the desktop it reverts to the grey screen with a repeating cycle of the spinning gear appearing (spins for a while, stops, disappears, reppears spinning, stops, disappears, over and over) - never progressing beyond that stage.
I decided to reinstall the system and things have been fine for the past few days. Today, restarting again resulting in the same problem.
I've tried several things without success. I disconnected all peripherals, reset the PRAM/SMC, ran Disk Utility from a install volume and ran repair and permissions (no problems reported). Tried safe mode startup - a progress bar appeared but never fully progressed and could not get to the desktop.
Recent changes included updating the OS to 10.7.3 and Adobe Photoshop CS5.5 - no recent hardware changes. No bluetooth devices connected.
Any thoughts? Thanks -

Thanks -
I've reinstalled the OS today and am back up and running.
But, since this is twice this has happened within the past week, I'm worried about might be causing this issue - besides bad luck. My Mac is usually rock solid - can't remember the last time I've had to reinstall the OS in the past few generations of OS X.

Troubleshooting iMac Startup Problem

I've been trying to troubleshoot a problem with my mid-2007 iMac 24" where it sometimes will not startup. I can hear it turn on when I press the power button but it doesn't chime. I can also hear the fan. I don't boot from the internal drive as my main drive and instead boot from a larger firewire external drive attached directly to the iMac. When the iMac won't start up, I usually let it sit for about ten minutes and it will startup again. Yesterday though, this procedure wasn't working but it did eventually startup after I left it alone for several hours to run some errands.
After using it for about an hour, the internal drive unmounted and disappeared from my desktop -- I got the usual "disk was not properly ejected" warning when it happened. I ran Disk Utility but the drive did not show up on the list. I also ran System Profiler and it did not locate the drive either. Instead it said "There was an error scanning for Serial-ATA Devices".
My question is this, could it be that the internal hard drive has been slowly failing and has been the cause of the startup problem? Does the internal HD have to be in working order to be able to startup properly and boot up from my external? I've been told by others that it does appear to be a logic board or video card problem and I've inspected and reseated the RAM and it has not been the issue.
My iMac is out of warranty and I'm gonna have to bring it in for repair. If it is the internal drive that is the problem, I don't want to shut it down for any reason until I'm ready to have it repaired. Thankfully, I have full backups.

This sounds very similar to my situation. When I restart the computer it usually gives me the grey screen with ?-folder. Using the Install Disc to boot, I ran Disk Utility but the drive did not show up on the list. I also ran System Profiler and it did not locate the drive either. Instead it said "There was an error scanning for Serial-ATA Devices". Wait a while or repeated restarts eventually boots the system. When I can get the iMac to boot up I used the Install disc and ran Disc Utility Repair but no errors were detected. I have ran the extended AHT a couple of times and no errors were returned.
Did you resolve your problem? Bad HD?

SpeedGrade is in a continuous load loop, and won't open

I'm on a Macbook Pro
OSX 10.9.5
2.6 GHz Intel Core i7
When I go to open up SpeedGrade CC or SpeedGrade CC 2014, I get a continuous loading loop that sticks at the loading screen, and it never crashes or opens anything. Adobe CC says it's up to date. Please help!
Thanks,
V

At this point, you probably need to uninstall & reinstall ... but with a very specific process.
First, download the Adobe CC Cleaner app. It runs in a "command window" screen like an old DOS program, but works very well. The instructions say to use your system program uninstall utility however ... doing that did not help when I needed to do this. I suggest using the CC cleaner app itself for everything ... as in ...
Install & run CC Cleaner app from Adobe's website. Use the CC Cleaner Tool to solve installation problems | CC, CS3-CS6
Use it to clean out SpeedGrade and all it's references, prefs & all ...
Then using the Creative Cloud desktop control app, download a fresh copy & install it.
Hopefully this will take care of your troubles ...

MacBook pro when windows 7 has startup problem and Mac os doesn't work

I installed windows 7 on my MacBook pro and it did work well. But now windows has a startup problem and "startup repair" couldn't solve it, so I can't use both Mac os and windows and my laptop has become completely useless. Any suggestion?

Reboot and hold down command-R at the sound of the chime, that should take you to the Lion recovery partition, if it does go to disk utility and see if you have an OSX partition at all.

Update 1.02- Now continuous restart loop- New Classic 80Gb

Went to synch 2-week old 80Gb classic. Prompted for update, waited until after synch. Then clicked update. Came back later and iPod stuck in a continuous restart loop. Reset/Restart does not work, computer doesn't see it untils it boots...hosed.
Any ideas...?

This was finally resolved, so I thought best to post the results.
*Call #1 to Apple:*
Poor English speaking tech, very hard to even get the address right, and very little product knowledge resulted in returning it to Apple. Within 2 days prepaid box arrived and I shipped back. Within a week, the reply that nothing wrong, or may have been corrected via diagnostic testing- software update, etc.. Worth noting no charge.
Received it back, turned on and woohoo...the menu. Plugged into and opened iTunes. First thing I noticed..FORMATTED WINDOWS (FAT32), even though it left me, and I told Apple I was a Mac user. OK- who cares, as long as it works. Did a full synch, the iPod restarted and right back into the loop of restarts again.
Call #2 to Apple:
This time an English speaking, knowledgeable tech who, for the first time, had me put the iPod into disk mode (center/menu until logo, then center/play until disk mode) and for the first time the iPod was seen by iTunes.
He walked me through the restore, menu came up and began synching. All looked good so I let him go at 40Gb of stuff takes some time. BUT as synch completed, iPod restarted and was stuck in the loop again.
Call #3 to Apple:
This call started bad, tech not really understanding history of things so far, new case ID, and had me doing things already done. However, eventually a product specialist and the tech support call we all dream of. Methodical and full knowledge of the iPod. First thing, clear out old iPod software update files to force new download. Then log in to another user (we all have one right?), and going through the restore in the fresh iTunes. Brought some tunes in from CD, synched and finally a working iPod. OK, now back to the other user.
1. Trashed iTunes library file in my user, and moved the iTune Music Library.xml to the desktop.
2. iPod to disk mode, opened iTunes, cancelled erase and synch, did restore, and manually put some tunes on it. All good.
3. Went through adding tunes and checking, all good.
4. Final was Import the previous iTunes Music Library on the desktop, and synch only a few items. All good.
5. Synch some more, couple hundred, and all good.
6. Final synch all music and let it go. All good.
7. And finally, add photos, TV shows, movies, contacts, calendars, etc. and all flawless.....
So...appears the end result was either a corrupt iTunes Library file or iTunes Music Library.xml file. Note that other iPods (2 shuffles, and a 3G 20Gb) continued to synch without issues, only the new classic suffered from the corrupt files..
As a note: As far as Apple Support was concerned I didn't like the fact that each time new Case ID's assigned, or that I had to constantly explain the "sequence of events" leading up to the current call. In addition, the first call was worthless and had I talked to tech from call number three, it would have been fixed then without even sending in.
Anyway, hope this all helps someone...problem solved.

Startup Problems with my iMac

I am trying to troubleshoot a startup problem on my iMac and can't seem to get it to boot at all. The problem began last night when I tried to the whole HD to a previous time point in Time Machine. I only went back to earlier the same day to correct another issue that I inadvertently created. In an attempt to keep this short, I will stick to the facts.
Last night I started the restore process by booting from the OSX dvd and then restoring the machine from a TM backup from earlier in the day. (external firewire drive) Everything seemed to be moving along fine with the estimated completion time several hours away, so I went to bed. This morning I woke up to find my machine will not start up. I get the normal chime and the white screen but then it is as if a gray curtain falls down the screen and soon after a dark gray square appears in the middle with the instructions to turn off the machine and re-start it, in several languages. This happens whether or not the OSX DVD is inserted and regardless of any keys (shift,c I've tried so far) that are held during startup. I am trying to startup from the original disc that came with the machine (OSX 10.5.6), but I get the same result if the disc is ejected and I try to startup from the HD. All peripherals have been removed.
What am I missing? What is the trick to getting the machine to boot from the DVD?

Success! Not sure what happened, but this time I started up from the 10.6 dvd (SL) (instead of the 10.5 that the machine shipped with) and did the restore from Time Machine (same as previous attempts). This time it seemed to work and when I restarted the iMac, it came up like normal.
Thanks for the link Carolyn. I did do disk utility a couple of times and it consistently came back OK. It's now going through a very long TM backup, I guess it must be a new one even though all the previous ones are still there in the TM viewer.

I have a user on an iMac 10.6 connected to our domain. She uses Outlook web access for email on our exchange server. Last week she received the following message which is randomly preventing her from sending emails. She claims no attachment was involved in the original email when this all started. I have not been able to look at her account as she is out of the office but maybe someone else dealt with this issue. I realize this may not be Mac related but thought I'd give it a try. She did say it occurred once over two days while working on a PC but it continued over the past weekend.
If an internal user tries to send a message with infected attachment using Outlook Web Access, it may report the following error message: The action could not be completed because of a conflict with the original item. The conflict may have occurred when an existing item was updated on another computer or device. Open the item again and try making your changes. If the problem continues, contact technical support for your organization.
This is because F-Secure Anti-Virus for Microsoft Exchange has detected a virus in the attachment. If the user tries to send the message again, the message will be sent but without the attachment. At the same time a blank message with an attachment named "Attachment_information.txt" will remain in the user's Drafts folder. The "Attachment_information.txt" will contain information about the virus detected in the message.

PS - have found other posts indicating that clips smaller than 2s or sometimes 5s, or "short files" can cause this. Modern style editing often uses short takes ! Good grief I cannot believe Apple. Well I deleted a half a dozen short sections and can export, but now of course the video is a ruined piiece of junk and I need to re-do the whole thing, the sound etc. which is basically taking as much time as the original. And each time I re-do it I risk again this lovely error -50 and again trying to figure out what thing bugs it via trial and error instead of a REASONABLE ERROR MESSAGE POINTING TO THE CLIP IT CAN'T PROCESS. What a mess. I HATE this iMovie application - full of BUGS BUGS BUGS which Apple will not fix obviously, since I had this product for a few years and see just hundreds of hits on Google about this error with disappointed users. Such junk I cannot believe I paid money for it and Apple does not support it with fixes !!!
If anyone knows of a GOOD reasonably priced video editing program NOT from APPLE I am still looking for suggestions. I want to do more video in future, but obviously NOT with iMovie !!!

This thing happend,, it say Disk utility stopped repairing "Macintosh HD" disk utility can't repair this disk
Sorry, possibly you need a new hard drive or try reformating. First
you can try something like http://www.alsoft.com/diskwarrior/ it has been known to repair disk that DiskUtility could not. YMMV and they don't give it away.
If Disk Warrior can not repair then you need to Reformate the drive. Make sure you have a back-up in place no matter what.

Disk Utility will tell you something about it's SMART status:

Error in Remote Web Access - "An unexpected error occurred. Please try again. If the problem continues, contact the person who manages your server."

I have set up the RWA and I can log in to the web console with my server account. However when I click on any of the shared folders I get this error:
An unexpected error occurred. Please try again. If the problem continues, contact the person who manages your server.
Does anyone know how to troubleshoot this?

I had this very same issue with one of our customer's servers that was running Windows Server Essentials. I ended up calling Microsoft about the issue. I hope this helps someone. This originally appeared on my blog: http://techspeeder.com/2014/01/14/remote-web-access-error-an-unexpected-error-occurred/
Troubleshooting Steps:
1. We were getting unexpected errors while accessing shared folders remotely
2. The tech found IIS handlers were missing
3. She went to IIS > server level ( parent level) and added managed handler mapping :
Name: svc-Integrated-4.0
Request path: *.svc
Executable: System.ServiceModel.Activation.ServiceHttpHandlerFactory, System.ServiceModel.Activation, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35
4. Added script mapping:
Name: svc-ISAPI-4.0_64bit
Request path: *.svc
Executable: windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll
Name: svc-ISAPI-4.0_32bit
Request path: *.svc
Executable: windir%\Microsoft.NET\Framework32\v4.0.30319\aspnet_isapi.dll
5. Ran IISreset.
6. We were able to access resources in Remote access, then.
