Stuck in an Endless Restart Loop

My Mac Pro 8-core running OS 10.5.4 is stuck in an endless restart loop. The problem started when I tried to allow read & write access on my Macintosh HD to another user. Even though I only applied the permission change to my internal hard drive, all my externals suddenly became locked and I could not access them. When going to set permissions on the externals, it was listed as "custom" and I could not alter them. I went to the terminal to try to allow access to the external drives, but the terminal failed to load. That's when I tried restarting my computer and it's now rebooting constantly without ever loading.
What I've tried so far:
-I can't load the OSX install CD because the computer is unresponsive to the open tray command by holding down the mouse click.
-The computer is unresponsive when I try to start in safe mode.
-The computer is unresponsive when I hold down command option O F to force the tray open with firmware.
-I reset the PRAM by pressing command option P R, this is the only keyboard command that has worked so far, but still nothing.
-I unplugged the computer for 10 minutes and plugged it back in. Still nothing.
Any help on what to do next would be appreciated.

I'm having a similar problem.. my early 2008 3Ghz macro when cold starts up the fans rev up and click its off. this repeats for up to five minutes, then i get a chime and then it shuts off. this is repeated for a will as if it is warming up. after about ten minutes it gets as far as finishing booting up and still shuts off. only after about 15 minutes this operating system is stable and does not shut off.
when the computer is fully warmed up it shuts off and restarts fine..
it has recently had a new logic board. can it be the power supply..
please any one got any ideas???

Accidentally deleted /var/tmp directory and I'm now stuck in an infinite restart loop

So guys, I was poking around and I accidentally deleted that file. I am now stuck in a restart loop that sometimes ends with a white kernel stop sign in front of a black screen. When that happens, I am forced to restart my computer again.
Every time I restart, the loading bar is about 1/5 of the way there when a series of messages show up on the top left of the screen. I took some pictures of the message, and I have inserted it below.
Again, the directory is /var/tmp, and I am not sure if it was /private or not. I'm sorry.
The kind person who fixes this issue will get my undying respect.
Again, thank you guys very much.
I own a 2012 15 inch MBP, if that helps.

In addition to what greg sahli suggests, also issue the commands:
chmod 1777 /var/tmp
chown root:wheel /var/tmp
My commands and greg sahli's suggestions ASSUME that you did not delete other things essential for the normal operation of Mac OS X.
Otherwise you will have to follow mende1's advice and reinstall Mac OS X.

Stuck in an endless authorization loop...

Just downloaded DEATH RACE 2000 -- a personal favorite -- using iTunes 7. When I try to watch the movie, I get a gray screen and a dialog telling me that this computer is not authorized to play the M4V file... although this Mac IS authorized. OK, no big deal, I'll just play along... eventually, a dialog appears informing me that my Mac is now authorized. However, there's STILL no audio or video, although the progress bar is moving so the movie is supposedly playing.
Close iTunes, open it again, same story. Even tried running it from the iTunes Movie folder, and the same error occurs.
Is anyone having this same problem with movie downloads?

I am having the same problem...Authorized music plays fine, but no purchased video will play, I go into the endless authorization loop that you speak of.
Anyone have any ideas?

Tiger Endless Restarts Loops

Before installing Virtuedesktops, all was fine with my Macbook.
Now, after the installation, the Mac have problems in rebooting. It keeps restarting after showing the desktop and I can't even open any folder or run any programs.
What I have tried:
1 - Delete the Virtuedesktop files and fodlers --> Nothings happens
2 - Boot in safe mode --> OK but can't do much
3 - I have reinstall the mac OS X --> Same problem.
4 - In safe mode. Archive the "Previous Systems" files into my external HDD and delete the "Previous Systems" files in the Mac.---> Still similar problems.
Question:
Do I have to reformat the HDD and reinstall the OS X?
This method will be a much longer process. How do I reinstall my old apps? Do I just drag and drop the "Previous Systems" files back to the Mac?
PS: Sorry - I'm new to Mac. Just bought 2 weeks ago.

The test indicates the old account probably has either a corrupted preference file or login item.
While in Safe boot mode, go to System Preferences -> Accounts & check the list of login items you see, looking for anything related to Virtual Desktops or anything else that looks like it might not belong there. (Some items, like iTunesHelper or iCalAlarmScheduler are from Apple & should be left in place.) "Hovering" the pointer over a listed item will pop up its location, which may help you decide. You can also list anything you are wondering about on the list here & we will try to help you decide about it.
To deal with preferences, open ~/Library/Preferences/ & look for a ".plist" file related to Virtual Desktop, probably starting with "com.virtualdesktops" or just "virtualdesktops." (~/ means your home folder.)
Removing the offending item to the desktop or trash & logging out & back in should solve the problem. If not, post back with your results.

Flash Builder 4 endless compile loop?

Sometimes my Flex projects get stuck in an endless compile loop. What I mean is, they start building, go to a certain percentage and then restart at 0%. I have to cancel the build process and do a Project, Clean just to get the project built so I can debug.
Anyone else experiencing this? I'm unsure if this is related to having Aptana Studio 1.5.1 also installed on the same eclipse, but that's the only other major plugin I have installed.
David

Hi David,
yup, I know this error. I reproduced it several times.
If you use the automatic binding, by dragging and dropping an EntityService to a Datagrid, some code is added.
For example a definition for the callresponder, a call for this callresponder, a creationComplete for the DataGrid.
If you do this several times and then start you delete some parts of the generated code for bindinng, the described error happens quit quickly!
Then you do not(!) get a clear compile error, but it compiles for ever .
You can solve this in two ways.
Take this project out of your workspace ( you do not habe to delete it from disk).
Find the still existing code snip, that produces the error and delete it and use clean compile. To find the error is tricky!!! because DataGrid3 belongs to Callresponder 2 and so on and you don not(!) get clear messages from the compiler.
I use the automatic code generation, but do not use the automatic binding. Then this kind of error does not happen any more!
Hope this helps!
Martin Zach
P.S: This has nothing to do with Aptana.

Airport Extreme & Express in unending restart loop

After downloading and installing hardware/software updates (unsure which it was) for Airport Extreme and Express, the Airport Utility has for 24 hours been in an endless restart loop. I can't force quit the Airport Utility. There seem to be mention of a lot of similar problems and suggested solutions, but none make sense or have worked for others. Help anyone?

T440s Windows 10 Realtek Audio restart loop

Have downloaded the latest windows 10 realtek audio driver from the lenovo site and when you install the driver there is a message like "driver installation is a 2 step process, 1) uninstall current driver and restart 2) install new driver" The uninstall works and the restart happens, but after booting up again the new driver does not install - instead the exact same window comes up about the uninstallation, resulting in an endless restart loop. Any fixes ?

The installation of the driver mentioned in the topic fails both in automatic procedure started from the Device Manager as well as in the installation wizard. Device Manager fails with timeout and the wizard fails with 0xC0000374 which seams to
be some kind of heap corruption.
Please see if the link below can be of any help. It has helped quite a few users with Realtek HD audio driver installation problem .......

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.

4th Gen Classic in Restart Loop

Greetings,
I have a 4th generation classic, 60gb iPod stuck in a continuous restart loop.
I've been able to put it into disk mode and it is recognizable by iTunes where I did a restore to it after which it went back into a restart loop again. I then put it back into disk mode and erased said iPod with Disk Repair and did a zero out on the drive. Restored again via iTunes and, after resetting, has refused to come out of its restart loop.
I can load music onto it and everything but use it as an actual iPod.
Is this the logic board needing a replace or is there something else I can do?

A. I've done a restore 3 times and it still does the restart loop as well as after a full wipe via Disc Repair. Aka, then it must not be a software problem
B. I can ONLY get it recognized on my computer in disk mode. Aka I can not use it as an ipod to play music as it refuses to load up out side of disk mode. It falls right into the restart loop after a soft reset.
Fortunately, I've been able to get all of my music files backed up from the disk mode.

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.

Endless restarting and flashing on Apple logo loop

My iPhone 4s with iOS 8.1.2 is in a endless rebooting loop. I cannot turn it off. I cannot restore or recovery or anything in recovery mode or DFU. all of my programs are up to date. When I plug it in the wall it start in a endless loop, apple logo appears, after 3 second a white page blinking and then it restart again.
I checked the battery and power cable and sensor, both of them are working well.
please help me, how should I do? what`s the problem?

As I posted to another similar question, I got this problem fixed followingly (is that a word?):
For those like myself who don't backup your device regularly and fear you may lose data, there is hope. My 4S started looping the apple logo at start up and wouldn't go anywhere from there, the screen went black and then the apple logo would appear again over and over... Browsing around I found that recovery mode and resetting the phone was suggested, some suggested downloading software to fix the issue but I found that rather dodgy so I decided to try something else.
Now I must remind you that opening your phone will void your warranty or such if still applicable, my phone's maybe four three years old and I've replaced the screen myself so I figured I'd try something to shock the phone back into life somehow (think the last popup reminder said I hadn't backed up in 29 weeks so meh).
What I did was opened up the back cover and removed the battery, plugged it back into the charger (other end in my mac) but the loop would still occur. I plugged and unplugged a few times, unplugging right after the apple appeared, hoping for this to "confuse" the phone which was so stubbornly stuck in "recovery mode" (from what I've understood through other threads). Notice that the phone did appear to turn on without the battery connected, but plugged into a power source (not sure if that should happen since after dead battery you need to charge a while until the phone wakes up), just something mildly interesting I picked up on.
This did not appear to have any effect tho, but I decided to pop the battery back in its place (I did leave out the little black plate that goes between the battery connector and the motherboard, covering the antenna cables connecting point, not sure if that had any effect or how it would effect fully working phones (I only use this phone as an "ipod" since the sim reader has been dead for some time, but I still use the camera and music)). Pressed the power button and noticed the apple logo stayed for longer than before (became hopeful!) and eventually made way for my home-screen!
That's how I got it working, don't know if you can do a similar thing with other models. And sorry for rambling on like that, that's just how I express myself and I can't afford to hire an editor to work my internet posts. But I can leave a TL;DR version.
TL;DR Iphone 4s stuck on logo loop? disconnect battery and do magic.

Macbook Pro stuck in restart loop with fresh install

Hello!
I have a Macbook Pro (Mid 2009) that I have been running Snow Leopard on up until now. I had been meaning to upgrade to Mavericks for a while, but had just never gotten around to it. Over the last month or so, my Macbook has been running really slow, hanging on the spinning beachball every few minutes for a few seconds (sometimes up to a minute or so). So I figured a clean start might be the best way to go, and while I'm at it, I might as well upgrade to Mavericks.
I backed up all my data, and then I created a Mountain Lion bootable usb (I had trouble making a Mavericks bootable usb from Snow Leopard, and since I had bought Mountain Lion for my desktop, I just decided to do a fresh install of that, and then upgrade to Mavericks). I had no problem booting to the usb, erased my hard drive and did a fresh install of Mountain Lion. However, after the install on the usb, my mac restarted and got stuck in a restart loop. It will chime, show the apple logo and spinning gears for a few seconds, then the gears stop spinning, and then the mac immediately restarts (this time displaying a message saying the mac has recovered from a shutdown in a number of languages), and the same thing happens again.
I was able to boot into the recovery partition, checked the permissions, found some that needed to be fixed, ran the repair permissions, verified the disk and was told the disk appears okay. Tried to then restart and same thing.
I have reset SMC, NVRAM, and none of these change anything. I booted in single user mode and ran fsck -fy, and recieved a message saying modifications were made, rebooted, same thing.
I have booted in verbose mode and the system restarts at the same point every time, right after displaying a message that says
SMC::smcReadKeyAction Error: (and then something with "BEMB", it goes by really fast so its hard to read exactly)
I have managed to boot into safe mode, but this has not made a difference. On one of my boots into safe mode, I went ahead and made a Mavericks bootable usb, and restarted the process: wiped the drive, installed mavericks, but I am in the exact same situation. I can still boot into safe mode.
I have seen some other issues that people have posted, but most involve the system freezing after the apple screen (not restarting) or do not involve freshly formatted HDs.
I'm just tying to find out if this is a hard drive issue, or if my mac itself needs to be retired. It has had a pretty long life (being 5 years old), and one of the RAM bays doesn't work (it is only running 4GB of ram, not sure if that can cause a problem with the boot cycle).
Sorry if thats a lot of information, I've been trouble shooting this for a few days. But thanks for any help you can offer!
A strange note:
-when booting from the mavericks usb, I got stuck in the restart loop a couple of times. I managed to get past this by clicking the mousepad a few times right after the gears finished spinning. The mouse became visible, the apple screen shifted color a bit (went from a bluish gray tint to an orangish gray tint), the mouse became visible, and I got to the reinstall menu as normal. As far as I can tell the clicking may have been coincidental, but it was the only time I was able to boot the usb, and I wasn't going to risk restarting to test that, and then not be able to boot again.

Hey, thank you for your reply! I didn't have everything backed up, but I have a lot of my important stuff saved, though, so that's somewhat of a relief..
As far as my hard drive is concerned, would I have to send it in somewhere to get it fixed or would I just have to get a brand new one? If so, how much? Sorry if I seem a bit amateur, but this computer is my first personal computer, and I'm really lost without it!
