Mac Mini OS X Corruption - won't boot up!

Mac Mini OS X Corruption - won't boot up! Its Power Off Automatically after showing Mac Logo in start up. But I can able to detect the Harddisk and CD/DVD using Options.

Thanks, woodmeister50, that looks almost simple enough ... BTW - the Mac Mini didn't come with a DVD. No DVD at all, and no CD/DVD-ROM drive. I am guessing: nothing really says this out in the open that I have seen, so I have to guess that the "Recovery HD" is a set of files on the same Mac mini HDD with the OS X. Is the Recovery HD a partition on the Macintosh HD, separate ffrom the System partition (OSX)?
I think Recovery Disk Assistant must be an app, but I don't see it in my top-level Applications folder, in Finder (nor anywhere else). And I don't see it in system Utilities, either, in the Launchpad. (That Launchpad display really is beautiful!). And RDA isn't shown in the Mission Control panel, or the Desktop.
Any ideas where I might find Recovery Disk Assistant.app file? Is it found on the Recovery HD (along with the OS X setup files)? And, is it accessed by booting into the OS X Utilities with Command+R?

My mac mini sudenly frozed and won't boot in again.

while i surf the net with safari, safari just close itself and the screen was dim with a message to restart . after i do restart my mac mini it can't log in to os and fail to install new os from cd. i did test hardware and it error 4MEM/1/40000000 . is it because my kingston ram that i just replace 1 month ago? i think it just works....

I am having a similar issue to the original post! However, I have not upgraded my RAM. I've only had my Mac Mini for 2 months. I have the dual 512MB RAM sticks which came with the Mac Mini from Apple. The case has never been opened.
My system won't boot into the Mac OS GUI. I just get dumped to the Darwin prompts. I can't successfully re-install the OS from DVD/CD. I run the Apple Hardware Tests from disk and get "4MEM/1/40000000".
I noticed this when I tried to login to my machine on 6May07.
Does anyone know if the brick and mortar Apple Stores can replace the memory under warranty on the spot? (The closest Apple Store to me is about a 3 hour drive). I hate calling the Apple hotline.

Mac Mini, OSX Leopard Server: Won't Boot

I have a Mac Mini Server that 's been stable and connected to my home network wirelessly.
But the signal strength has been so-so.
So I added an Airport Express Modem in my system and installed the adminstrative CD that came with it.
The Mini saw everything and set up the Airport Express fine and it worked great...for about 3 minutes.
I was checking the speed when it became non-responsive. I shut it down and tried rebooting, and the loading ball spun and spun and spun and did nothing.
I tried rebootijng from a regular OSX Disk and it was non-responsive.
I got it into diagfnostic mode, got a diagnostic screen showing me everything was working, but it still only shows a spinning ball forever and won;t boot.
Using an external DVD, tried using the administrative disk, but I also couldn;t get into it.
No matter what I've tried, the "loading ball" spins and spins and spins...and won't actually load anything.
Ideas, suggestions? I HATE to hit the genius's this time of year..IT'll take FOREVER!!!

Smells of a low-level hardware failure.
I'd usually suggest ordering a spare Mac Mini Server, and rolling in your backup, but Leopard is a very long time ago and jumping to Lion is going to be involved. Which leaves you to scrounge something old enough to run Leopard or Snow Leopard, and moving to that.
Or you get to brave the local Apple store, yes.
If you don't have good backups of your disk, stop working with the server Right Now, as - if this is a disk-level error - further activity on a failing device tends to reduce the likelihood of eventually recovering the data.

Mac Mini with Striped RAID won't boot

Hello all,
I have a Mac Mini Server which I've installed Lion (not server!) on. I set it up with a striped RAID (two internal 500GB HDDs) and it worked great for weeks until I shut it down for the first time. Now it won't boot back up... I just get the Apple logo and the spinning wheel. When I boot off a rescue drive, I don't see any errors related to the RAID. It just says it's "Online." None of the buttons for things like Verify and Repair seem to do anything when I click them.
When I hold down option upon turning the power on, I see "RAID 1" and "RAID 2." I don't know where those names came from, they aren't anything I set during the Lion install and RAID setup. I've tried selecting both, and all I see is the Apple logo and spinning wheel.
I'm hoping some of you have ideas! I also tried holding down the power button until the Mini rebooted itself, but that has not helped.

Hi, I think you'll have to Install Lion again to an external drive, or even a big enough Flash Drive to get any further.

Mac Mini Mid 2010 windows won't boot

After using boot camp to install and run Windows 7 on a Mac Mini Mid 2010, I restarted the machine to boot OSX. Now I can't boot back to Windows. Boot Camp seems to be working fine, but the partition I created doesn't appear to be bootable. I don't know what to do or how to solve the issue. How can I solve this issue?

I will venture that you were unlucky. Twice could be a coincidence. However, if it were to occur again, then you have a pattern and I would imagine that Apple would think something in your home/office is causing the issue and be less likely to want to swap for another.

Mac Mini Server (Late 2009) - Won't boot from Windows USB/DVD

Hello all,
I have a Late 2009 Mac Mini Server (Macmini 3,1) with OS X Lion.
I have created a Bootcamp Windows Partition on one the 500GB Disk using Bootcamp 4.0.
After the partition is created, I have tried installing Windows 7 using the Bootable USB method as well as using the CD Drive from the attached SuperDrive.
But all I encounter is either the blinking cursor or after the "Starting Windows" logo, a BSOD.
Any tips/help on how to proceed?
Thanks in advance.

Cattus,
Thanks for the reply.
I did use BC to create the USB stick. I also tried to create the USB on a WIndows Machine (just in case). But still can't boot from USB. What's the WIndows Utility you mentioned?
Also, according to the this LINK, The firmware for Macmini 3,1 should be MM31.0081.B06 (EFI 1.2).
However, the BOOT ROM info on my mac mini says MM31.00AD.B00 and I can't seem to update the EFI Firmware. I get a message "This computer does not need this update" when I try to run the MacminiEFIupdate.pkg

Mac Pro Dual Quad Core won't boot OS/X, but plays fine with Linux/Windows

I've got a Mac Pro Dual Quad Core won't boot OS/X, but plays fine with Linux/Windows. I've tried all of the following initial tests as suggested on forums:
-Ram swaps
-Alternating video card in PCIe slots
-Trying alternate video card
-resetting pram and smc
-Multiple tests with memtest86+ over 26hrs and no failed ram
-Multiple tests (8-12 cycles) with apple HW diagnostics and no problems
-Firmware is approved firmware for early 2008 model...no new updates.
Gentoo livecd works fine and I even installed to hard drive and it boots fine with it. In addition to above tests I also ran a linux stress test putting all 8 cores at a load of 22 for 2.5hrs with no problems.
Memtest86+ for 24hrs+ yields no problems.
Where problems occur:
Booting off hard drive, DVD or firewire yields an immediate curtain of death and booting off a new snow leopard DVD dies about 25% into the install.
Looking at error log and a quick dmesg shows "Package 0 didn't get an HPET" and complains about AppleIntelCPUPowerManagement.kext. Google turns up illegal uses of this, so doesn't apply to my use case.
I'm a bit stumped since all was working well until one day it was non-stop curtains of death and can't get them to go away.
A logic board replacement at $1100 is not a feasible option for something that works on linux and windows, but not OS/X, is a bit disappointing and somewhat surprising.
Thanks for your help and advice.
Regards,
Marcos

Someone here once thought they knew EFI and Open Firmware a little, and used some commands from OF library that an Intel EFI Apple system didn't like. New logicboard.
Of course to run or boot OS X and see video you need EFI based card. The presence of some PC cards can block OS X from booting.
The fact you get part way through SL DVD, pull all the drives, put in a new drive and format it from SL DVD.
Most of the things you tried are what are more common with PC hardware. Including where people have tried and failed to install OS X on unsupported hardware.
I suppose it is possible something tried and failed to modify the Mac's firmware.
If you have Windows running, and you have WD drives, WD just posted new Lifeguard utility which is what I use to do a good job of stripping a drive down and recertify it for reuse, works wonders. Maybe same for other makes with vendor utility.

Do you have a Time Machine backup or clone? If not,
all is lost if you have in fact deleted your OSX partition
and you will have to do a reinstall from Recovery HD
and install all else.

If I upgrade my Mac mini to Lion, can I still boot from Snow Leopard on another drive/partition?

My Mac Mini with Snow Leopard doesn't boot

When booting, I see a gray screen, a blue screen and another gray with the
little round activity meeter which suddenly stops, and the picture freezes.
Is there any good step-by-step guide for troubleshooting this?
I'm not sure I have 10.6.2, but I keep it upgraded.

Is your Mac Mini purchased new since August 28, 2009? If it is, are you using the Mac Mini Snow Leopard installer disc? Only the disc prebundled with such Mac Minis will install a Mac OS X on those Mac Minis.
If it is older, are you using the retail 10.6 installer disc which looks like * If not, only those discs, which are not labelled OEM, Upgrade, or DropIn will install 10.6 on your Mac. You can't use the disc prebundled with another Mac on it.
Use the startup manager to boot the discs:
http://docs.info.apple.com/article.html?artnum=106178
If the hard disc is not apparent, a data recovery software may be necessary if your data is not backed up*:
http://www.macmaps.com/backup.html
If your hard drive is present, read what I said earlier about booting off the correct installer disc, if the hard disk is not able to boot, and booting off the Snow Leopard installer. That will allow you to repair the directory of a backed up system. If your system is not backed up, and won't boot, then look at my backup link above to recover your system first before attempting any installation or directory repair of your hard disc. Any attempt install a new system on a hard disc that won't boot an existing system will only result in a corrupted system. Any attempt to repair a directory may result in worse issues if the hard drive is marginal. So at least having a recovered data set if not a backed up one is essential before doing any repairs on your system.

My new Mac mini (refurbished by Apple) won't play nice...

I just bought an Apple-refurbished Mac mini and when I turn it on, it goes right into Open Firmware (Unix??). Also, when I type mac-boot at this prompt I get the "?" folder. To top that off, the CD/DVD Combo drive won't accept a CD or DVD, it springs out slightly and the mechanism doesn't pull the disk in. Is there something I'm doing wrong? I've already taken this to the Apple Store in Chicago for repairs after working with AppleCare Support. After getting it home, it's having the exact same problems I originally took it in for.
My wife has worked with a Mac Server before and asked if there's a locking mechanism on the unit anywhere. Well I can't find it...
Any help would be GREATLY appreciated. BE
Mac mini Mac OS X (10.4.2)

There's no locking mechanism, and judging by the fact the mini won't start up normally and won't let you insert the install disk to try and set it up from scratch, it sounds to me like it is fairly fundamentally faulty.
Did the people at the Apple store give any indication of what they did with the unit when you took it in? It's odd that it's in the same condition now as it was before you took it there, and suggests they may not have checked it over at all, or that the fault the unit has is perhaps intermittent and can be induced (or corrected) by the sort of movement and vibration inherent in transporting it.
One way or another, I would not accept that unit as functional, and would suggest you call Apple and in view of the fact it did not work at the outset, ask for it to be replaced.

Mac Mini 1.42 G4 will not boot Folder With Question Mark Plus more....

I have a major problem with my mini, It was working ok one minute then it froze completely so I had to shut down via the power button, But when I restarted it I got the folder icon with the question mark in, I've tried various things to get it to boot, I also put in the 10.5 disc to do a hardware test,I've since found out that that is the wrong disc to do a hardware test with. Now I can't get the disc out I;ve pressed the eject key and pressed the mouse button on start up with no look, Also when I press the Option key to select the start up disc all I get are a round arrow and and arrow pointing left. When I press the right arrow key on the keyboard I get some text on screen saying something about firmware and an option to type shut-down or mac-boot, If I type mac-boot the screen goes grey and nothing seems to happen.
So I'm stuck now with a Mac Mini with my 10.5 disc stuck in it and refusing to boot.
Any one any ideas as to what I can do?
Thanks
Ade

As you no doubt have recognized by the use of the 10.5 install disk, the folder icon with flashing question mark means that the system can't find a valid and viable MacOS installation to boot from - a problem which could have been existent for some time but not yet developed into a failure, or possibly caused directly by the forced shutdown.
Your thought to use the install disk was a reasonable one, though at this point I wouldn't have wanted to run a hardware test so much as boot to the installer and from the utilities menu once it has started up, then run Disk Utility to test the hard drive for errors, and attempt to repair any found. The reason for that approach is because while the symptoms you describe can certainly be caused by a hardware failure, it is much more common for this to be the result of a failing or corrupt drive - which at the very least Disk Utility is good at diagnosing.
However, now you've got the 10.5 install disk in the drive, the question becomes why it cannot be found by the boot loader (the screen you get when you've booted with the Option key down) and thus can't be used by the system to get it booted up.
It could be that the disk is not a valid installer for that system - in which case it would have to not be a 10.5 retail installer but instead have come from another system. Alternatively, it could be that the drive didn't correctly load the disk, thus doesn't know it is there. This might explain why trying to eject it by holding the (left) mouse button down during bootup doesn't seem to have worked.
To be clear however, you need a wired, USB mouse to eject the disk during bootup, and it must be connected directly to the system or via an Apple keyboard which is not an aluminium model. The (left) mouse button should be held down from hearing the startup chime, and until the disk pops out. If that technique doesn't work, and there is no indication of any life from the drive when you try, it may mean your mini needs to be opened up to retrieve the disk from the drive.
Also, be aware that while the boot loader screen appears relatively quickly after the Option key is held down, it can take a few minutes for a disk in the optical drive to be read and appear there. In most cases, I'm sure users typically wait long enough while wondering what, if anything, is going to happen, but it can take much longer than expected!

Mac mini g4 power pc won't download please help I'm new mac

I have used Mac mini g4 2005 run Mac os x 10.3.7 but I can't Download. I don't know why is my forts Mac and I think sale because I don't know how download and also won't open YouTube too please help thanks how configure please thanks

Thanks for the suggestions.
I did try the DIMMs one at a time, plus in pairs, and no luck.
But I think you were on to something about trying a different CD. I don't have the System CD for this machine, nor do I have a System 9 CD. I had tried an OS X 10.3 installation CD and a Disk Warrior CD, but those wouldn't work. I did find an Apple Extended Care CD (which had a version of TechTools on it) that I got with my Powerbook, and lo and behold, the G4 started up off of that! So I turned off the machine, connected the hard drive again and restarted. It booted up off the hard drive and I was able to connect to the network and everything.
But then I got greedy. I thought whatever was wrong was now magically fixed (magic being my most relied upon Apple repair tool) and popped all the RAM back in. Turned it on, kernel panic. Darn. Took the RAM back out, turned it on, kernel panic. Uh-oh. So I put the RAM back in and tried to start it off the Extended Care CD again. It started up OK from the CD. Then I tried to boot from the hard disk again, and it booted up just fine, no problems at all. I had to reset the clock, but everything works.
So I still don't know what's going on with the machine. Maybe it was the battery after all, but it couldn't boot until something was reset. It's a mystery, I guess.

New MAC Mini w/OSX Lion - will not boot from USB or external optical drive when attempting to use BootCamp to install Windows 7?

The University recently purchased 6 brand new MAC minis for deployment in classrooms I support. I am attempting to create a dualk--boot environment comparable to our existing computer systems, only these machines wil be running MAC OS X Lion and Windows 7. After following the procedures outlined in the BootCamp on-screen prompts, and attempting a few techniques I found in the tech support user-base, I am still unable to get the MAC mini to boot up from the USB flash drive, or from an external optical drive, so that I can complete the installation of Windows 7. When using the Boot option key at start-up, all devices are displayed suggesting that they are being properly recognized, however the computer boots to a black screen with an error message indicating that "No bootable devices are found - press any key to continue." I am able to boot into the computer's internal drive, but not from any external devices. I fully expected that the semi-automated BootCamp procedure properly prepares the USB device for booting, and for installing the Windows 7 OS.

Meh, with the price they take for a drive in Denmark, I don't think it's worth it... They take around 160 $ for the drive (that's the cheapest MacBook drive I could find), and I am not even sure that's the one I need.

Intel Mac Mini Core Solo - Kernel Panic on Boot

I was wondering if anyone who has purchased the Intel Mac Mini is having issues with Kernel Panics during the booting sequence?
I got a Core Solo from the local Apple store (couldn't wait to play, I'm waiting on the Core Duo I ordered online to come still ). The first thing I did was fire it up check it out for a few minutes, then I put the install disc in and reinstalled a clean OS, with less options because I'm planning on hooking it up to my TV so I don't need space hogs like Garageband etc on my TV computer. I got the updates that popped up, then shutdown the computer. I took it out to the living room and hooked it up to the tv and I got a black message about needing to restart (a kernel panic) right when the blue progress loading bar comes up on boot. I spent a while with it trying to figure out what was wrong, ran the Apple Hardware Test, booted it fine in Safe Boot. Finally I got tired of it and reinstalled the OS again.
It was fine for a day, working fine out on the tv. I brought it back in my room to play with a few things like Darwine, etc. Shut it down, came back an hour or so later booted it up and got the kernel panic on boot. Safe boot still worked fine. I spent some time trying to look for panic logs but didn't see any. I ran the disk utility and did a Full erase and it worked fine. I reinstalled the OS again. Ran MemTestOSX and it worked fine. I left it running the Apple Hardware Test for about 6 hours or more, and it performed perfectly.
This morning it still seemed ok, except sometimes on a cold boot when the blue progress bar screen should come on... my monitor just shows black and the light on the monitor goes inactive. So, I press the button on the back to sleep it, then bring it out of sleep with the keyboard and the OS is sitting there booted.
It seems like a weird combination of software and hardware problems, but maybe it's all hardware problems. I can't get past Safe Boot working when the OS stops loading. Right now the computer is working fine.
I'm waiting for my Core Duo to come in the mail and verify that it works flawlessly, then I'll take the Solo to the store and ask them to look at it.
Anyone have any similar experiences so far?

It seems like the mini is doing alright so far. I think maybe the full erase solved whatever issue it was having. I also got my Core Duo Mini yesterday in the mail and it's performing like a champ. Definitely a nice machine.
I'll close my question for now, since the Core Solo Mini seems alright. But, as a warning don't get on Front Row's bad side. I tried force quitting it because it was taking too long to load the videos folder and then tried shutting down from a terminal and ended up having to turn the machine off.
