OS X :: When Updating Boot Cache Then Shut Down Hangs Automatically?
Dec 13, 2009
I have a problem. I have installed Leopard on a partition on my MacBook. When install successfully completed, my Macbook restarted but it hangs and does not restart so I had to switch the power off by the power button. I then switched my MacBook back on to complete registration and finally got into Leopard.I then updated using Software Update and then restarted but it will not restart. When I try to restart i get presented with a window telling me that "Updating Boot Cache". I then click "OK" but it hangs on the desktop wallpaper and pointer. I have tried to leave my MacBook for half an hour but it is still hanging on the desktop wallpaper and pointer. Same thing happens with Shutdown

Macbook Pro, running current iTunes and OS X 10.9.3, iTunes library on an external hard drive. Â
Whenever I try to update my podcasts, I get the spinning beach ball, iTunes stops responding. All other aspects of iTunes work flawlessly. I've called support numerous times - no solution. Only thing that is strange is the kernel tasks go sky high...and other programs stop running due to running out of memory.Â

I have the 2.53ghz with 4gigz of Ram MacMini from Xmas 2009.A few of you know that I had been trying out different SSD's before finally jumping on with OWC 60gig SSD. I've had it for about 2 months now and it works great except I've recently been having my computer freeze and the beach ball of death appears constantly when on Safari and sometimes iMovie. After shutting down the computer manually, sometimes booting up will leave me at the grey screen for minutes before i shut it down and wait maybe 30 mins before i fire it up again, which usually works 9/10 times.
I also noticed the beach ball delaying certain processes like loading Safari or a webpage. For example, I have my OWC External hooked up via FireWire800 with just my music and videos, however occasionally if im browsing thru websites or loading a program it'll cycle the external and have the beachball as if trying to load something before proceeding. It is more an annoyance than a problem.
I ran disk utility on all my drives as well as the Apple Hardware Test CD to see if maybe my Logic Board was the problem. I did the general test as well as the indepth test, both show negative signs of a problem.Can anyone shed some light on what could be the problem?Should I put the factory drive back in and take it to Apple to run their diagnostic test?Could the SSD be failing? (I could RMA it, but didn't know if its an Apple issue vs OWC)

I don't really remember what I was doing but it just turned off then when I tried to turn it on it would make a sound like when you turn it off. I think its the hard drive stopping but its like high pitched to low. and it kept doing that then after a few times I got it to start up.

For several years now, daily, I've ran through a number of different HDD's under relatively stable (although hard-working) conditions (Seagate, WD, and now Hitachi). None of them ever crashed until recently (WDD Caviar Black 640MB). But there have regularly been periods of time (before that) in the past when I would hear what sounded like sharp-twang on Shutdown - like a noise from a toy ray-gun or something. It's happened a few other times in the past, although an HDD has never failed shortly thereafter.

My powerbook will not start up all the way. It suddenly went off yesterday and did not give any noticeable warning. I left it alone after trying to start it up several times. I tried again today and had the same problem. I will here the motor for a few seconds and then nothing. Also, it did come on twice, went off both times when titled the entire laptop up. So, if I tilt it at anytime it automatically shut off.

I need to populate the bays of my new MacPro 2.66 with 5GB RAM. The stock HD turns out to be a Seagate 250GB HD ST3250820A. I've found them online and wonder if I just should RAID three or four of them as opposed to one Seagate 500GBs or 750 with 32GB cache? These would all be a Raid run by Apple software not a RAID card.

My G5 has developed a problem with restarting. Basically if I restart it gets to the grey screen with the apple logo and the spinning thing but shuts down as soon as it gets to the blue screen. This will happen for as many times as I care to restart it. The only solution I have come across is to take out the SDRAM modules and swap them round (any combination will do as long as they are swapped) and bingo, it starts again as if nothing was wrong.
Initially I had four 512k modules from Crucial and recently replaced them with two 1024 modules from another manufacturer to see if that would solve it but it didn't. Zapping the PRAM also didn't work. I should say also that around the same time it developed a habit of shutting down mid-use, but this was solved by switching the processor usage from high to automatic.
Information:
G5 2ghz dual
Mac OS X (10.4.10)

. Ok so I installed Logitech Control Center so I can change the function of the buttons on my mouse. So when it was done installing it said that the computer had to restart, so I pressed ok, right when my Mac shut down, this pop said something about Boot Cache or something. The pop up only showed up for about 2 seconds and disappeared. I think Logitech Control Center reset my PRAM because I had to retype my network password and my date/time when my mac restarted. Is this normal? I deleted the Logitech Control Center icon in the System Preferences pane because it may be interfering with my Mac. Is there anything wrong with my Mac or is there nothing I should be worried about?

Over the last year I now and again get this strange this happening where the computer would freeze and the fan would come on at full speed and be very loud. It also started happening when I turn off the computer for a while and turn it back on again. It would not start up and the fan would just kick in. The only way I could get it going was to manually turn the machine on and off until it would eventually turn on properly. Sometimes I would have to do this 4 or 5 times.
Then today the computer just turned itself off automatically. No warning, nothing, just click and off like when you have a power cut, but there was no power cut. So I ran a quick hardware test from the OS installation disk and it said that it detected 2 faulty RAM sticks at startup. I was worried it might be a logic board problem but that has come back on the test saying it is okay.
Would having faulty RAM cause the above to happen? And how reliable is the hardware test that comes with the Apple OS installation disk? I am praying it is just RAM and nothing more expensive. I am gonna clean out the fan today, and dust things down a little bit just in case it is a bit of dirt or something, but I would be interested in other people's opinions.

I recently found that the cause for my macbook pro hanging on shut down was due to Kaspersky running in the background. Because quiting it before shutting down every time is annoying is there a way to automate the quitting of an application when I request my computer to shut down?Â

I've been reading this site for a while now, first time I'm posting. I recently purchased 8 GB of RAM for my 2010 13" MBP. There are two 4 GB DDR3 PC3-10500 1333mhz sticks. When I install them in the laptop my computer does not get past the apple logo boot screen (the spinning disc freezes). However, I can boot into Windows (boot camp) without issues.
Also, when I pair either of the 4 GB sticks with one of my old 2 GB stock sticks the laptop boots up fine in OS X. The system profiler registers it as 6 GB of 1067 mhz RAM (the stock sticks are 1067 mhz)

I have a iMac(20") for about a year now and its ran great up untill now. It is hanging on boot. Sometimes its the white screen with apple logo and spinning gear, other times the screen goes blue and i can see it load a mouse cursor for about 2 seconds, then the screen goes through a few shades of blue and the spinning gear re-apears with no apple logo. The computer then loops. I tried to boot to safe mode, but as i have the sound off i am not sure i am holding the shift key at teh proper moment. If anyone has any advice, please, please let me know. my mac reinstall cd is about 8hrs drive from where i am, and i do not know if mac issues replacement cd's.

I'm troubleshooting an iMac G5, Tiger 10.4.11. The first problem was a -50 error, which prompted me to repair via Disk Utility (which failed), and finally to replace the catalog via DiskWarrior (which succeeded). After another boot crash, and two instances of reinstalling the system, these are the results:
1. I can boot from system CD.
2. I cannot see the internal HD in Disk Utility on the CD.
3. I can reinstall the system successfully using Archive and Install.
4. Immediately after reinstalling system, computer boots up normally.
5. Computer will eventually crash with a spinning beach ball.
6. After a forced restart, the startup stalls at the grey apple logo.

2010 MacBook Pro 13'
Mac OS X Snow Leopard 10.6.4
Windows 7 Ultimate x64
Bootcamp 3.0.2
I'm trying to install Windows on my computer, and the install works fine, with no issues. On my very first boot into the desktop, everything looks OK. But when I reboot Windows, it freezes on "Installing device driver..." and then I have to press the power button to turn the computer off. I noticed that the device driver it's trying to install is "IEEE 1394". Then, when I restart my computer it freezes on the "Welcome" screen and I have to restart, only to be met with the same "Welcome" screen freeze every time. I have tried all 3 different "Safe Mode" options, burned several different Windows install discs and tried to repair my Windows install using the Windows DVD, but the repair program says that my Windows version isn't compatible with the disc version, even though it's the one I originally installed it with. I even saw in one thread that a guy fixed this same exact problem on his Mac by pressing the power button in anticipation just before the freeze. I tried that solution many times and it didn't work either. I also saw on another website some console commands I can use to try and resolve my issue, but if I cannot access a console, how am I supposed to use it?! I noticed that "Loading Driver C:System32DRIVERSCLASSPNP.SYS" hangs for quite some time before loading the welcome screen and crashing there. A few times I even notice that it would freeze on that process itself. Either way, I can't get into Windows. I've tried every solution I could find, and none of them worked at all. I'm really mad and sad right now because this is so frustrating. I just want to be able to get Windows on there so I can play my favorite games, use Office and work in Visual C++ Express Edition.

I have a (check sig) and just tried to install the Windows 7 RC 64-Bit onto a Bootcamp Partition. I had been using the Beta way back, but had cleared that partition in advance for a clean install. With that I had no problems...ran the 7 beta fine alongside OSX. I followed the same procedure I had done for the beta install with RC, following the guide on the internet. Everything seemed to work out peachy, Windows 7 booted fine, I added all my settings again. Then I switched over to OSX to eject the disc, which was fine although the boot in was quite sluggish. I set the boot drive as "Macintosh HD" in System Prefs, and proceeded to try to boot into Windows 7 again....this time it was no go.
The screen came up with the white cursor on black, and then the "Starting Windows" showed, with the animation above it. At some point during the animation, it just froze. My fans were at normal speed and everything. I tried many times, same story. So I thought I would shut down, boot into OSX, and try to erase the partition. That didn't work either. When booting into OSX, the start-up chime sounds with the white screen, then the gray Apple logo shows up....and that's where it stays. I reset the PRAM, no luck. What could be the reason it hangs on BOTH boot processes? Because for a short time they did both work, and I could not have erased my OSX partition or anything because I did boot into it once after installing the Win7 RC. I also can see both partitions when I boot holding Option...

After recently doing a fresh install of Snow Leopard, it was working great for about a week, and now it hangs at boot and flashes the Apple Logo, a NO sign, and a folder sign. I booted in verboose mode and it say that it could not load drivers.
I had this problem before and I used Leopard's (10.5) Archive and Install feature to fix it.
Where is this located on SL (10.6) ? I DO NOT want to loose my data

I have a mac pro running leopard (purchased in 2/08) and it was running beautifully for almost 2 months with no hangs, crashes or freezes. Then, for some reason, today when I turned it on, it would not boot. It would get to the apple logo, then just sit there for a few minutes, then reboot itself and the same thing would happen. I pulled out the ethernet cable, unplugged all usb except keyboard/mouse and it would then (sometimes) boot into the system, log me in and present me with the UI.
I then quickly performed a soft reboot and it would get to the desktop. However, I can only use it for anywhere from 30 seconds to 5 minutes before it would completely lockup. The clock freezes, the mouse freezes and it just sits there forever. I have tried booting into Vista (BootCamp) and it also freezes before startup is complete. If I hold down Option and then select the System disk, it will either just hang forever or get to the desktop and then freeze again....................

All I get is the grey screen and the little circle with the rotating fan blades. Then they stop spinning and it just hangs.
I cannot boot up. Is this a bad hard drive? Â Are there other keys I could hit to make something work?

Which one of these 500gb drives is better? I've been browsing Newegg for two hours now reading reviews. The Seagate drives seem to come with bad firmware that causes performance and cache recognition issues. The Samsung drives have a high failure rate. Whats the real deal? Has anyone here had any bad experiences with either drives?

I have a new MacBook Air running Lion. Every time I use my backup software, it changes the permissions on my external drives, and I have to change them from read only to read & write, so I've gotten in that habit. At one point, I noticed that the permissions on my internal *startup disc* were read only, so I (foolishly, I now know) changed the permissions on the startup disc to read & write, with apply to all enclosed items checked. As I continued working, I got messages that a number of extensions could not be used and will be disabled (or something like that). I decided to reboot, so the computer could reset and hopefully correct things.
When I tried to boot, it hung up on the grey screen with the Apple logo and the spinning clock/gear. I let it spin for a while, then forced power down and tried to boot in safe mode. The progress bar appeared as it's supposed to, but when the progress bar finished, it went back to the grey screen and hung up again. I let it spin for over 40 minutes before powering down, just in case it was doing diagnostics or something. I don't have access to the original OS DVD (nor do I have an optical drive to put it in). Any way for getting the computer to boot, at least in safe mode?

So I want to update my graphics card driver to see if that will help but for one I cant find which drivers to download and the ones I have downloaded don't work just saying that they cant find compatible hardware for the drivers.
I don't know if its anything to do with boot camp or its just me not knowing how to update drivers properly but can someone point me in the right direction?
I'm running Windows XP SP3 32bit, on my iMac. The graphics card is a Nvidia GeForce 9400, no M or GT as far as i can tell. Boot Camp version is 2.0 or 2.1 cant remember.
I tried the nvidia website but it doesn't have that model listed so i don't know which one to download, and the ones i did download, as i say just said they couldn't find compatible hardware.
