Mac Mini constantly freezes, Wont boot from install disc.

About 6 months ago my mac mini started freezing (getting that grey screen prompting you to hold the power button until it turns off) it did this every few hours or so. Eventually i got tired of this and have tried multiple times to wipe the HDD and reinstall snow leopard. I try and boot via the install disc but it just spins at the apple logo. I also tried reinstalling windows 7 on the bootcamp partition but again it gives me any error. I fear the hardrive might be totally busted. Any help?

Mac Pro 2008 won't boot from install disc - black screen

Hello,
I recently purchased a new hard drive to replace the original that came with my Mac Pro 2008. I was able to format the new drive using Disk Utility. I am now at the point where I need to install OS X onto the new drive, but the computer refuses to boot from the disc. The disc is recognized by the computer (I can access the disc and am able to use the BootCamp applications, etc.) but I just get a black screen when trying to boot directly from the disc. The computer boots fine otherwise.
I have tried the following:
I have tried using both the gray install disc that came with the computer and the Snow Leopard Install DVD disc.
I have tried booting using the "C" key and the "option" key but still receive a black screen following the chime (I've held these down for several minutes).
I have tried restarting from either install disc using the Bootcamp Assistant.
I have tried running the installation software to get it to restart from the disc.
I have tried a combination of the drives, i.e. trying to boot from the discs with just the new drive installed, just the original drive installed, and with both in bay1 and 2.
Everything results in the computer starting up, hearing the chime, and then nothing..just black screen. I have the original drive partitioned with BootCamp with OSX Snow Leopard and Windows 7 installed (I don't know that that matters).
I am at a loss as to what to try next. It doesn't seem like the superdrive because it is recognizing the disc, it just won't boot from it.
Any help is appreciated, thank you.

Clone should be a must and easy to do and learn (learn by doing! 2)
6800 would 'qualify' as 5x70 series flashed etc and same rule: 10.6.5
In the past there was 10.4.6, 10.5.6, but not 10.6.6 - even though strong need for such a DVD.
10.6.8 DVD would be excellent
Lion or ML - buy, download, make an installer flash card would be what I would do at this point.
Then keep both - dual boot as you learn and test and see what ML does and waht you had that required Rosetta to support PowerPC. See www.roaringapps.com about that.
With Carbon Coyp Cloner - was share, now commercial, great utility been around since 10.2.2 at least - this time 2003. 10 yrs.
You can clone the system folders, you can even selectively choose. You can skip copy of most of your home account and do that separately to another drive if you want.
Clone Windows with Paragon or WinClone and use Windows 7 or 8 DVD to do a system repair (automatic) or to edit the BCD file. It can and should - and all you do is boot Windows 7 DVD w/ only the one drive present and go at it. Piece of cake. But yes, Windows gets fussy if you change or remove or move. BCD to the rescue. A proper program for cloning like Paragon's "Clone OS" meant for going from disk drives to SSDs, knows that and how to do it.
Back to how to clone etc:
Clone
Disk utility has RESTORE which will also clone your system but not the Lion Recovery partition. Oddly Apple did not 'endorse' making bootable clone of the system which works too but most choose Carbon Copy Cloner - it works more consistently; it allows for smart update of the backup volume. Both can backup to a sparse disk image if desired.

The DVD is dependent on your hardware. And your hardware changed. The drivers for the 5780 and 6xxx are bundled in the OS and lacking. Minimum build thing.
Put the new drive anywhere you want. Does not matter. Can move it later. Can be drive bay 0-3 or a Firewire external or under the DVD drive.
When you clone pull the old drive and boot from the newly cloned.
After that keep a backup clone around all the time. Takes less than 10 minutes to do a smart update to copy just the changes to keep it current. So you have working copy of the system. I keep Clone "A" that I keep "as was" the system as of last month or whatever (like 10.7.4 before upgrade to 7.5).
Comes easier after doing it once and have all your ducks in a row.

Will Not Boot from Install Disc & 4SNS/1/40000000: TG0D - Thermal Sensor?

*Will Not Boot from Install Disc*
I used the "option key" approach with the gray start up disk. At first it ejected the start up disk. Then I nudged the disk back in the machine and it showed on the screen as an option. I clicked on the start up disk image and it finally loaded.
But, it won't accept the start up disk when holding down the "C" key at restart.
*4SNS/1/40000000: TG0D*
I did an Apple Hardware Test and received the following diagnostic:
Version: 3A121
Test Suite: Extended Test
Loop Count: 2
Result: Failed
Failure code: 4SNS/1/40000000: TG0D
*Thermal Sensor*
A search for the failure code 4SNS/1/40000000: TG0D brought up an Apple Discussion topic entry stating: That error code indicates a problem with a thermal sensor. It could be not working or possibly not connected. You will need to take it to Apple for repair.
Would a thermal sensor have anything to do with it not starting up when holding down the "C" key at restart? What are thermal sensor problem symptoms?
*User File Folder Opened Up*
The machine also starts up with my user file folder opened up rather than with a blank screen as it normally should
I completed a DiskWarrior rebuild on the disk and verify disk shows it is fine.
Any suggestions on what to do next with these issues?

The answer was in your post: "You will need to take it to Apple for repair."

My Mac Mini Will Not Boot From Install Disc For Re-Installation

I've tried all (at least the ones I've found) workarounds to get my Snow Leopard Install Disc to boot, but it will not. When the computer boots normally (without the DVD), I can insert the DVD and access it from there. However, when I try to use the utilities on the disc, it requires a reboot that ends up telling me to turn off my computer. I have a Late 2010 Mac Mini and I have yet to try booting from a disc, so I don't know if this is a new problem or an old one. Any help would be greatly appreciated.

Unplug everything from your computer except a wired keyboard/mouse and the monitor. If your Mini still won't boot from the install DVD try resetting the PRAM and SMC.
Intel-based Macs: Resetting the System Management Controller (SMC)
Resetting your Mac's PRAM and NVRAM
If that doesn't fix the problem remove any RAM (if you upgraded) and replace with the Mini's original RAM. There is also this document you might want to read, Mac OS X: Gray screen appears during startup.
If that all fails I would take the Mini to the Apple store. It should still be under warranty if you bought it late last year.

Power mac g5 wont boot from install dvd

i have a g5 power mac i had to replace the hard drive when i try to boot from the disc it freezes on the gray screen with the apple im use the retail dvd for the ppc can anyone help

Hello! You may not be waiting long enough if there's been a new drive installed as the OS on the dvd will be looking at the new drive to see if it's been formatted. It may take 10-15 minutes or longer to fully boot from the install disc. Tom

Will Not Boot From Install Disc

Upon a Verify Disk check I received a "Volume Header needs minor repair" notice.
Because it is necessary to boot from another disc to repair the header, I attempted to boot from the install disc. I tried restarts holding down the "C" or by selecting the start up disc in System Preferences/Startup Disk. I've tried each of the these several times to no avail. The machine will not start from the install disc. It keeps starting from the machine hard drive.
Are there any other suggestions how to force it to start from a startup disk?

The installer disc problem is still a concern but in the meantime you can try booting to Safe Mode. Run Disk Utility again from Safe Mode and see if it still reports problems. Boot normally afterward.
[Mac OS X: Starting up in Safe Mode|http://docs.info.apple.com/article.html?artnum=107393]

[Mac OS X 10.4, 10.5- Computer shuts down during Safe Boot|http://support.apple.com/kb/TA24054]
Safe boot mode runs a directory check command similar to that used by Disk Utility's repair. In Tiger it ignores some stored information (cache) that is normally read that speeds up the boot process, and it moves some other caches to the trash. It also uses only System fonts and disables all Startup Items, third party items, and any Login Items.

Booting from Install disc Stalls at strange Mouse & Batteries Screen

Any thoughts/suggestions/answers would be greatly appreciated...
I have my hands on a friends iBook G4 purchased in April 2006. They were having problems with it and decided to wipe the drive and re-install the OS etc.
They got it wiped but could not get thru the installation process due to errors. They assumed it was a scratched install disc, and gave it to me to fix.
Upon receipt, I put in my Tiger (retail, not computer specific version) disc and booted via holding down the 'C' key. Got thru the first grey screen, then thru the grey screen with the grey Apple logo on it, and then up pops a screen I've never seen before; and the process stalls here.
This screen looks like two outline images of the Mighty Mouse from its underbelly. Image one is showing you where to install the batteries, and image two is showing you where to turn it on. And on image two, where the laser is, it's flashing red.
Here's a picture of it @ http://adairnet.com/ss-mac-install-stall-screen.jpg
I couldn't get past this screen so I booted it in Firewire Target Disk Mode into my other computer and used Disk Utility to fully wipe the drive (thinking there may have been some odd file on it causing this issue). That didn't help; when I booted from the Tiger disc again, I stalled at the same spot.
Then I discovered a way past it - it was only by plugging in an old single-button USB clear Apple mouse into the USB port, that caused that screen to go away and proceed to the Tiger installation screen.
I tried this several times, and consistenly, the screen would always come up if no mouse was plugged in, but as soon as I plugged the mouse in, immediately it went away and continued on as normal.
I was able to complete the installation process and everything seems to be working as it should now. I'm just dying to know what this screen was for and why it came up.
Other things to note - even after I have a successful/working OS on the iBook, if I try to boot from any disc containing an OS, I get this same screen/situation.
I did discover the reason the initial install failed was due to bad RAM, which I've replaced and checked and is working fine now.
I've also checked the system with TechTool Protege and found no errors.
Also note that the iBook owner never uses any external or wireless mouse - just the trackpad, and has never experienced any issues with it.
And lastly, to let you know, I did reset/zap the PRAM, did the Open-Firmware resettings, and reset the battery/power-management too without any affect.
Could it be a faulty (or soon to go out) trackpad, disc drive, or USB port? Or something else? Any thoughts?

TIA!

i actually had this same issue and called and talked to tech support about it, they transferred me to a product specialist and told me the reason it would do this is the install disk is most likely not the original one that came with the computer
he said that if the install disk is different, it may not recognize the specific trackpad the unit is running since it could be a different build, and will than assume that the computer is using an external mouse. If it than doesnt register the external mouse, it will assume that the mouse just doesnt have any battery power.
it makes sense to me, i also was able to bypass the "error" by using an external USB mouse, and i know my install disks were just the family pack that came from the apple store, so i can only assume thats what could be going on.

IMac won't boot from install disc

My iMac has been running a little slow the past two days and so I ran Disk Utility. DU reported that I had the incorrect number of thread records and an invalid volume count. It instructed me to repair the disk by booting from the install disc. The problem is that when I try to boot from the install disc (after I choose the disc from the options), I just get a gray screen with the apple logo on it. Nothing else happens, no disc activity, nothing.
Anyone have any ideas as to how to get my iMac to boot from the disc and, ultimately, to get Repair Disc running from DU?
Thanks,
Rich

It should only take a minute or so at most to boot from the DVD.
If your sure you have the correct Install Disk for that iMac, I'd start over. Then if it still doesn't work then perhaps a trip to your Local Apple Service Provider with the Disk or Disk and iMac is in order.

Replaced hard drive, now can't boot from install disc to restore backup

Yesterday, my hard drive died (disk warrior informed me, that HD had irrecoverable errors, and my iMac would shut down unless it was booted from the Disk Warriorr disc).
Today, I have a new internal HD professionally installed. And when I brought it home, and installed Snow I got an error at the end of the installation "OS could not be installed, restart or choose start up disk" or something to that effect. However, on licking OK I got the snow music, and welcome movie nd eerything seemed to be working fine.
I can log in normally and have get to my desktop, but on trying to boot from the Snow Leopard disk (10.6), I get to the gray screen with the apple logo and hang. I have tried resetting Pram/firmware and also ran the fdisk command (twice).
It seems too much of a concidence that my hard drive and now my disc drive would die all in span of two days? I can hear the disc noise, but as I mentioned I cant get beyond the gray screen on trying to boot from the disc.
Suggestions?
Late Nov '07 intel iMac. And I did update the OS to 10.6.4. Install disc is 10.4.

Return it to the repair station.

Booting from Install Disc

This seems like such a simple question, but for the life of me I couldn't get it to work. I was helping a friend with her new MacBook Pro and tried doing a CD boot from the Install disc. The computer booted fine, but immediately went into the installer, and I could find no way to exit the installer without shutting down. How can I do a straight CD boot from the discs that come with Leopard and not run the installer (or at least how do I boot and then exit the installer) so that I can access other programs, run disc utilities, etc?
Thanks!

lowbarprods wrote:
I should have been clearer. Running disc utility was only an example. There are other programs I need to run from the hard drive, but only after a CD boot. How do I exit the installer and access the hard drive?
you can't, not easily. That's not what the install DVD is for. It provides a very limited version of the OS and all the apps you can run are in the Utilities menu.
according to this[macosx hint|http://www.macosxhints.com/article.php?story=20071105135450731&query=insta ller%2Bapplications] you can run some apps from your hard drive while booted into the installer but I haven't tried that and I'm quite sure that most things won't run because of the absence of required frameworks.

Mac Mini (PPC) won't boot off install DVD

I'm having a major issue with my 1.24GHZ G4 Mac Mini. What I want to do is reformat the HD and reinstall OSX. But for some bizarre reason the machine refuses to boot off any OSX install DVD I throw at. I've tried Jaguar and Panther as well. If I hold down the C key during reboot and wait for the Apple logo to come up, I get that but it goes no farther. I can hear the drive being accessed (and I know it's not fault because it works fine under OSX) and yet I end up getting stuck at that logo screen. I can reboot the system normally into OSX Tiger.
I also strangely cannot partition the hard drive from within Disk Utility.
Can anyone give advice?

Possible options/questions...
a) Have you tried using the original Install DVD that came with it?
b) Have you tried booting into Single user mode and checked the drive? (Hold down Apple-S until it boots into text mode and when you finally get the prompt type 'fsck -fy' without the quotes).
c) Also, you may wish to try resetting the PRAM immediately before booting from CD. Let it reset THREE times (hold down Apple-Option-P-R or WinKey-Alt-P-R until it has chimed 4 times) and then hold down the C key to boot from your Install DVD.

Mac mini 2012 freezing on wake from sleep

2012 Mac Mini 2.3 i7, 4GB RAM and 128GB SSD.
I'm having a problem which has only manifested itself this past week where one of two scenarios occurs;
1) During normal use the computer sort of stalls, the curser turns into the spinning ball and the keyboard becomes unresponsive. Whatever apps are open freeze their current activity and there is nothing I can do but shutdown the mini using the power button.
2) If 1) above does not occur and the computer is left for a period of time it it set for display sleep, when it is next used mad woken from sleep the desktop appears on the monitor and gaskin everything is completely unresponsive with any apps running frozen at the point that the computer stalled while asleep.
I have the mini setup as a home PC and iTunes media server. It is left on 24/7 with the computer set never to sleep, screensaver after 10 mins and display sleep after 15 mins. It makes no difference which peripherals are attached or which apps or processes are running.
What I have tried;
- Shutdown, restart and reset the SMC controller
- Shutdown, restart and reset PRAM (opt+cmd+P+R)
- Disk permissions verify & repair via disk utility
- Restart holding shift into safe mode
- Restarted normally
The problem still persisted, so then I got medieval;
- Reinstated from a previous time machine backup (prior to problems manifesting)
- Reinstalled Mavericks from Cmd+R startup
Neither improved the situation, so....
- Booted in utility mode, formatted boot drive.
- Reinstalled Mountail Lion from recovery partition
Still getting the same thing.
- Reinstalled Mavericks 10.9.3 from the Mac App Store.
Still getting the same problem.
I'm fairly confident that this is not a software issue, but I am now at the limit if my Mac knowledge! Has anybody had a similar problem?
If this likely to be an SSD failure on the cards or a logic board issue?
I gave now booked a Genius Bar appointment for Monday but Any help or advice would be appreciated.

On number 2...
See if it's related to this...
It also seems to be related to later OSX versions, like 10.8.x & 10.9.x
The 2012 macs (and later apparently) (also later OSX versions on earlier Macs can do it also), not waking normally from sleep after hours being in sleep. (noted here ...

Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts (Users & Groups in later OSX versions)>Login Items window to see if it or something relevant is listed.

Mac Mini (OSX6) freezes on boot if USB cable to KVM connected

I have a Mac Mini (OS X 10.6.8) that has started freezing with a solid grey screen on boot up (i.e., no Apple logo, no spinning wheel). The work around is relatively easy: all I need to do is disconnect the USB cable running to my ATEN KVM CS1768 switch, power down, power up and then reconnect the USB cable once the Mac desktop is loaded. While this just happened three times in a row, it doesn't happen all the time. The first time it happened last summer I spent an hour on the phone with Mac support (the computer was still under warranty at that point) and the very last suggestion they made was to disconnect the USB cables before attempting to reboot. (I don't recall precisely if the problem occured when my USB peripherals-- a Mac USB keyboard and mouse-- were directly connected to the Mini rather than being routed through the KVM switch, but I *think* it did.)
If anyone has a quick answer or can point me to a prior discussion of this same (or a related) issue, I would be most grateful

Hi,
Thanks for the response. I've been using Macs for a little over four years now but this is only the first time I have gone to the system logs (or any of the other logs available from the consolute utility).
The system log appears to be completely unhelpful. I got up this morning sometime after 6:00 a.m. and posted my first report (see above) at 6:48 a.m. (I don't have a record of the exact times of the boot up freezes.)
Following are the *entire* contents ot the system log covering this period:
Nov 19 01:12:15 WHW-Mac-Mini loginwindow[40]: loginwindow SleepWakeCallback WILL sleep
Nov 19 06:26:35 WHW-Mac-Mini loginwindow[40]: loginwindow SleepWakeCallback will power on, Currenttime:11/19/2012 6:26:35.019 AM - Waketime:11/19/2012 6:26:33.980 AM = Deltatime:1.038853049

Nov 19 07:35:13 WHW-Mac-Mini login[17714]: USER_PROCESS: 17714 ttys000
I assume that one of the two successful reboots that I did during this period was probably at 6:27.
The "all messages" log has some additional information from this time frame that may be useful:

Following this there were quite a few unsuccessful attempts to connect with my VNC server and little else that seemed noteworthy. Nothing that referenced anything to do with USB or USB peripherals.
And, of course, when I rebooted just now (in the hopes of getting a report from all of the logs corresponding to the exact time of the reboot), my Mini started just fine with no freeze up.

How to undo boot camp, wont boot from install disk in dvd drive

A few months ago I went through trying out boot camp and parallels. Now, I think something is messed up. I dont need either right now, so I just want to wipe out the whole system, repartition the drive, and restore to a blank new install of os x 10.5 leopard.
But when I put in the install disk, it wont boot up off it.
I tried holding down the c key while powering it up, and it just cycles through: hearing the drive whirl, a bling sound, and then repeating it again while the screen is blank. Finally, I held down the click button on the touch pad so it would eject the install disk.
Maybe this will help someone recognize part of the problem. Ever since messing around with boot camp and parallels, my machine wont "reboot". To reboot it, I tell it to reboot, then it hangs on the star like screen, then I have to hold the power button down, then if I do nothing, it tries to boot, but ends up in a dos looking screen saying no bootable device. So when I power it back up, I hold down the alt key, and then I have one choice: the hard drive. I pick that and it boots up ok.
So... I thought, well, maybe the boot camp is still messed up; maybe I should undo boot camp. When I start the boot camp assistant, there is only a "partition" and "back" button; nothing to "restore" the hard drive to just one partition.
What can I do? I want to wipe the drive and install a fresh install from my install disk.

Forgot to specify:
Im using an older Unibody Macbook (back when they were not all macbook pro's) 2008ish with Snow leopard 1.6.8
The thread you linked me to, Eric, shows the guy 'Niganit' with the eXACT SAME PROBLEM as me! He seems to have found out the problem but I dont see his resolve.
I just dont have the option to install windows 7 in any other form that a cd

Wont Boot From Install DVD

I need some help - I just brought home a brand new 27" iMac. It boots just fine from the internal HD. I need to do a complete Time Machine restore, as this iMac is a replacement for one that they can't seem to fix. Anyway, I load the Snow Leopard DVD, it pops up the OS X FInder icon, I tell it to go to utilities, and that I want to restore the entire hard drive. It then reboots - sort of. The DVD does some stuff, then the machine sits there with the gray apple logo on it. Been there now for 15 minutes with nothing happening. Any help would be greatly appreciated....
Jim

The first thing I would suggest:
- Shut down the iMac with the disc still in the drive
- Once it is shut down, Press the power button and hold down the C key on the keyboard in order to boot from the optical drive. (Hold until Apple Logo appears)
- Once disc loads, select a language and click the arrow
- The installer will prepare
- Up on the menu bar, click Utilities, then Restore from Backup
- Follow on-screen instructions
After that you should be good to go! Hope everything works out.

Mac Mini constantly freezes, Wont boot from install disc.
