Mac Pro :: System Shutsdown Randomly / Change Boot Drive?
Mar 26, 2008
I just received my 3rd replacement mac pro, the second one (same spec, apple replaced it for me) is here too. I'm trying to get the 'new' one up and running. They are both identical spec - stock Octo 2.8, with 8800GT, 500GB HD, and Airport.
Anyway, I bought a 750gb Samsung F1 on the 'old' mac pro and installed my OS and all my audio software and plugins on there. The 500GB drive holds only the audio data (no OS). Is it OK to just remove one boot drive from the 'old' mac pro, and put it in the new one? The are both the same spec machines...
The reason i ask is because i am getting very scary and random SHUTDOWNS on the new mac pro, all of a sudden - it will turn off, then briefly (for half a second) the fans will spin again, then it will die. It is as if something is tripping the power off, or messing with it at least. It's done it several times now. The first time i was doing a time machine backup, came back to the computer an hour later, and it was off completely. It wouldn't start for a while, then all of a sudden, it did on its own, a couple of seconds after i tried pressing the switch.
I tried to run the apple diagnostic test, and shut down after a minute or so. So i took out the stock 500GB hard drive (only the 750GB left in it now) and i'm running it again. We'll see what the results are. But anyway, has anyone done this? It should be ok to take the drive out and put it back in, right?

I have a 2008 macbook, out of warranty. My mac is running os x 10.6.4... I recently updated the laptop through the update section, and this is around the time the errors began. My next stop is perhaps reinstalling the operating system, but have to go out and buy the disc so thought i would check all options first.
It has begun random shutdowns recently, and i have tried checking the ram, checking power supply, removing battery to see if its caused by that, but so far nothing has come up. A mate of mine said sometimes you can work out the problem by looking at the logs to see what is causing the problem... Well, long story cut short,
the log is as follows from when i turned it on this afternoon, till the random shutdown, and then powering it back up again, i put the exact shutdown time in bold.

I have a problem... I use very processor heavy programs on my iMac G5 and up until about a year ago, I was getting along ok. Here's the gist of it:
1) World of Warcraft/ProTools etc. Prolonged use over many hours eventually caused my imac's fan noise to be unbearable. Even worse, my imac began randomly shutting down almost predictably during high processor use.
2) Was taken to an apple store (while in warranty) and only thing said was that it needed a new logic board. No explanation what actually happened to it. Logic board replaced. Few months later, it's happening again.
3) I am now outside an apple warranty and it will cost me $400+ to get it repaired. It is functional for regular internet use, but on sites like youtube, after a few videos it will likely shut down.
I have opened up my computer several times to inspect the capacitors, but they all look like new. I realize overuse is probably the problem, but if there is a fix I can do myself, I'd at least like to try. The problem is that I have no idea what to do I hate hearing "needs a new logic board" instead of "this part ____ needs to be replaced/fixed"
Specs: iMac G5 17" 2.0ghz generation right before isight macs.

Have had my imac for about a year and just recently my hard drive changed from "c:" to "+++++". I changed it to read "hard drive" and then a few days later it changed again to "5+". Why is it doing this?

I'm planning on using SoftRAID to mirror my boot system drive. Softraid allows to ADD another mirrored drive (or more) to an already existing boot drive without the need to reformat anything. From what I've read, it seems this software works well. I don't have anymore PCI slots so a hardware RAID isn't an option for me.
So here are my questions:
1. After I add a mirror drive to my already existing boot drive, will this new configuration cause the volume ID to change, as if it were another drive? in other words, will I have to authorize a bunch of my plugins again because they will think I moved them to another system? Cloning a boot drive doesn't allow to use the same authorization for most plugins. Will the added mirrored drive have the same effect?
2. Say one of these drives fails, and after I replace the faulty drive with a new one, then the software rebuilds my mirror boot drive combo, will the ID change again, or will the current plugin auths still work?
I have so many plugins now, I can bear the idea of losing my boot drive because it takes me weeks to re-serialize my plugins. Half these plugin auths go by BOTH the drive ID AND the Logic Board ID, so reformatting or getting a new drive (or reverting to a previous system, clean reinstalling a system etc) is a nightmare for me. When my boot drive fails It's more worth the trouble for me to purchase another computer and gain the extra speed. I feel the mirrored boot drive is a great solution if I can keep replacing the drives when they fail, for a longer general system life... If the RAID keeps the same ID that is..

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 Mac Pro, Intel quad core, with several HDs, 2 of which are bootable. One runs Mac OSX 10.4.9 (and houses Pro Tools HD 7.4) and the other runs 10.5.8 (with Pro Tools HD 8.0.2). The Tiger disk is absolutely fine but the Leopard disk will not boot from a stand-still. It can be booted from Startup Disk in System Preferences but if it was the last drive in use then trying boot from off results in a permanent hang on the grey screen. A workaround is holding ALT on startup and choose the Tiger disk but this shouldn't be happening so has anyone experienced this and solved it? I'm trying to avoid a full re-instal but that is an option.

we changed the hard drive in my friends G3 800 but now when you turn it on nothing comes up on the screen. It will act like it starting up, read the cd a little than sit idle.

I'm selling my old Powerbook G4. Before I let it go, I want to wipe the hard drive and reinstall OS 10.4. I also would like to run disk first aid because I suspect there may be some corruption. The problem: I still have the original system install DVDs that came with the laptop, but the DVD drive no longer works. It just spins the disks for a bit then spits them back out. I do have an external USB hard drive with plenty of free space. Is there a way I can copy the install DVDs (there's a Disc 1 and Disc 2) to the external hard drive, then boot from that drive and treat it like I'm installing from the DVDs? I also have my new MacBook Pro with a working DVD drive. Can I make my Powerbook boot from a CD in the MacBook's drive? If not, how else can I wipe my system and reinstall the OS without a working DVD drive?

My Macbook is 1.5 years old (13in, white, 2 GHz). About two weeks ago, it would randomly shut off. It would restart fine, but shut off sooner. Sometimes, it wouldn't even restart. Now, it's at the point where when I power it on, it rarely restarts past the white apple start-up screen.
My thought is that it is overheating. Are there any more ideas? What can I do to save my macbook?

I had a hard drive failure in my Powerbook. I had "copied" ,not "backed up" with backup software, the entire contents of the hard drive to an external one. So i installed a new drive, installed OSX from the cd onto it in a smaller partition. Started up, copied the entire contents off the external drive onto the larger part of the partition. My thoughts were to keep the newly "installed" OSX software/system separate from the "copied" OSX software/system by partitioning it. What i wanted in the end was to be able to boot from my "copied" system and be back where I was a month ago, and disable/trash/whatnot the "installed" system that was just to get it up and going. I'm running 10.4.11 on the G4 1.67 Powerbook. So, how can I boot from the original hard drive contents? It doesn't recognize or give a choice for the copied hard drive contents with the copied system and all, just the "new" installed system.

Does anyone know if there is a certain temperature that causes iMac's to shut down? I have been queuing up a number of movies in Handbrake and letting the iMac chomp away at them. For several months this was not an issue (this is a 2009 iMac 2.93 base model, no upgrades.) For the last week or two, I have come back to find the computer off a number of times.
Every time it has done it i was while Handbrake had the processor pegged at 100% for a long time. The 3 highest temps are usually the power supply, the Northbridge and the CPU and the highest I have seen them is right around 70C. Last night I did some messing around with that fan control program and got the fans to run higher while Handbrake was running.
I managed to keep all of the temps below 65C. I am going to leave it like this for a while and see if I have any more problems. I'm also going to try to cut back on the number I queue up at a time. I was setting up enough to keep it going for 12-14 hours. I don't actually think it was a time thing though as last night it shut down while my wife was using it and it was less than 2 hours after I started a batch.
Has anyone else had similar experiences? I see some people suggesting it could be caused by bad memory, but as mine only seems to happen with Handbrake at 100%, I'm thinking it's just heat.

recently my ibook keeps randomly locking up, it first started the other day when it got stuck on a blue screen at start-up eventually it came on, but kept locking up, no spinning beech ball just completely froze, i held down the power button to turn it off, i then had to wait at least ten minutes before trying to start up again, if i didn't it would get stuck on the blue screen, then something else weird happened, when i started up it came up with the mac set-up assistant similar to when you first upgrade, so i turned it off again and it went away, so i started up again this time i noticed that spotlight was indexing, despite it already doing that ages ago when i upgraded to leopard, so i thought this had something to do with it, because it kept freezing in the process, but today i turned it on, let it index and to my surprise it didn't lock up, so i went to play world of warcraft, and as soon as the login screen came up it locked up agai

So I have an old imac running OSX 10.3.9 and recently it started making a whoosh sound randomly at will. It sounds like a whiffle ball bat missing the ball. Also for no apparent reason it started saying "you have logged in" every time I wake it up. Any clue how to make these annoying sounds go away and or what may have started them?

I have an original MacBook Pro 15" (A1150) that randomly shuts down. Seems to be running very hot. I've already had to replace a bulging battery, and TechTool Pro has indicated a temperature-related S.M.A.R.T. failure with the HD.
If I downgrade the HD from 7200 RPM to 5400 RPM, will that help with the heat issues? Any other heat-related fixes? I know the 13" MacBook Pro suffered a random shutdown syndrome, but I didn't know if the 15" was affected too.

I have done some research on triple boot systems, and it appears that a third OS must be run virtually, but all the information I came across was a few years old. Microsoft is running a deal right now on Windows 7 for students so I would like to pick up a copy and try it out.
Is it possible to run 3 operating systems through Boot Camp 3.0? I am not interested in running a virtual OS.
Current Setup:
13" macbook pro
Snow Leopard and Windows XP through Boot Camp

Just an FYI. Tech Support at Allsoft states The Disk Warrior 4.2 Boot DVD will not Boot the new 2010 MBP's. They are waiting for information (software) from Apple.
Will need to use Target Mode or another Mac connected with Firewire till then. Boot from that then run DW from your MBP.

I have had several issues with the USB on my brand-new Core i5 macbook pro. It randomly disconnects USB devices. I've had the issue with multiple USB devices - same story with each one. Further, iTunes will only recognize my iPhone if it is in the port nearest the magsafe connector. The other port fails to recognize my iPhone entirely. Anyone else having a USB issue on their base 15" that was released today?
Furthermore, any suggestions of what to do about it? I'm having a hell of a time restoring my iPhone with this issue... And the Apple Store is over an hour away-I planned a special trip to buy this laptop.

So I have an external hard drive hooked up to my MBP via USB. I've noticed that every now and then (maybe every half hour or hour?) the drive spins up. It's actually really annoying, as the drive makes a loud sound as it spins up.
I can't figure out why it does this; the drive spins up and then goes back idle. Time machine is DISABLED, spotlight index on the drive is DISABLED as well. I use the drive solely for storing movies/music. There are NO applications installed on it. The only apps I have open are finder/preview/safari/firefox/adium/itunes. My guess is that some process is trying to access the drive for whatever reason now and then.

I have an external laCie Usb drive, that as the header implies, is ejecting itself randomly.
I use the first partition for general storage, the second is for TM backups.
It has never failed to finish a backup, nor has any large (5gb or larger) file transfer to the storage partition ever errored out. It appears to be completely random.

I have had my new iMac 21.5" for about 2 weeks now. Yesterday I picked up a 500 GB LaCie USB Drive to be used for my Time Machine drive. I have the drive connected directly to a usb port on the iMac. Sometimes when the iMac goes to sleep, when I wake up the iMac I get the dreaded "This Drive Has Not Been Disconnected Properly" warning.
I have made sure that the "Put Hard Disk(s) to Sleep Whenever Possible" option is not selected under the Energy Preferences. I have tried multiple usb ports, same issue. This isn't a constant issue, it just happens sometimes. Is there anyway to tell Time Machine to mount and unmount my drive when needed?
