Mac Mini froze during application install, need help

I was installing an application on my son's single core Mini and it froze. I can start it, but it soon freezes. In the old days, disabling extentions or starting off a CD could get the old G4 (and OS9) back in business. Seems my son can't find the box the mini came in or the disks that came with it (thinks he through them out).
What should I do?
G4 400 Mac OS X (10.3.9) SE, 605, 6100, 8100, 6500, 7100, 9500 (the last two are in operation today)

if you have no install disk, best to do fsck. http://docs.info.apple.com/article.html?artnum=106214 hopefully that will do something for you. when you say it "freezes" at startup it is hard to know what to tell you. there are different types of screens that occur with startup issues. this is an incredible article for startup issues--http://docs.info.apple.com/article.html?artnum=106464. do not worry that it says "10.3.9 or earlier". these steps are reliable for tiger as well. i hope that works for you.[:)]

Laptop Crashed During Maverick Install -- Need Help

Hello Everyone,
Before we get started, I just want to open with this info: My Macbook Pro is from 2008, and has a notorious habit of crashing... I hear what sounds like a rhythmic "ticking" sound from within the laptop, and everything on screen freezes up, and I have to do a hard-reboot. Other than that and a few graphical glitches with games, it runs seamlessly and had a good 19 GB free while attempting the update. Also to note, I have a BootCamp partition of about 30 GB for Windows XP. Additionally, I was an IDIOT and did NOT set up Time Machine or make a backup for my files, because, I repeat, I'm an IDIOT apparently.
So I had 10.6.8 installed -- Snow Leopard... and I heard there was a new free update to 10.8.0: Maverick. Of course it peaked my interest and I tried to install, not realizing it could potentially brick my laptop! Shoulda done some research
Anyway, here's what happened:
The download was successful, so I rebooted my computer and initialized the installation. Everything was fine, it said it would take about 50 minutes (even though it took a LOT longer)... and the install got not even half way before my computer crashed, with the infamous ticking sound. I was like, "oh sh**" because everyone knows that a crash during a major install is not good news. After I restarted the computer, it opened up the Maverick install again immediately, and attempted to retry... but within 10 minutes, an error pops up: "Install failed: OS X can’t be installed on the disk, because a recovery system can’t be created. Visit www.apple.com/support/no-recovery to learn more."
Of course at this point, I'm confused. I have no idea what that means. So I try to reboot to see if it would help, and the same error occured twice more.
This time, when I rebooted, I held Alt-Option to see if I could just select my HD drive and bypass the install. Nope. The only options were this: "Windows Partition, Maverick OSX Install, recovery-(something something)"... my HD drive wasn't even listed! This made me nervous. So, I selected the recovery disk option and it opened a menu with a few options, including reinstalling OSX, disk utility... etc. So I selected disk utility. I then proceeded to select my HD drive, and click "repair" in the first aid tab. It took about 10-15 minutes, but it successfully finished, giving me a green "Disk seems ok" message. This was a bit of relief. But now that the disk is repaired, how do I access it and exit the endless loop of Maverick installation? Do I need to reinstall OSX with my original disk/Snow Leopard disk?
Please help me recover my HD drive... I desperately need my laptop for school.
Thanks in advance. If you need any more additional info on my computer, I will be happy to try and provide it.

You can get replacement System Install & Restore CD/DVDs from Apple's Customer Support - in the US, (800) 767-2775 - for a nominal S&H fee. You'll need to have the model and/or serial number of your Mac available.

Late 2012 Mac mini upgrade ssd - also install parallels 8 and windows 7

Late 2012 Mac mini (16gb memory) SSD install - samsung 840 pro 512 gb. I am looking to install this new SSD as possibly a dual drive setup almong with the stock HDD 500gb in order to: make the system faster (with more storage etc.), possibly use the stock drive as a backup drive and I also want to run parallels 8 with windows 7.
I have ordered the data doubler kit from Owc and am wondering exactly how to setup properly. Can I simply install new drive in the upper bay (and move stock drive to lower bay)? Then migrate the data from the stock drive then after that's complete run the setup for parallels? I am also confused as far as using trim enabler or not? I was also wondering how much space/memory is recommended for windows 7 partition?
-Thanks in advance for your suggestions

NOTE: A small number of 2012 units were shipped with the drive mounted in the upper drive bay rather than the more typical lower bay shown in this video. If you have a 2012 or later model, you will want to determine the configuration of your Mac mini's drives prior to ordering. To do this, open Applications/Utilities/Disk Utility.app and click on the grey drive icon at the left-edge of the window. If you see "Lower" after the "Connection ID" at the bottom-left corner of the window, you may proceed using the standard installation instructions. If you see "Upper" then you have a special configuration which will need additional components, and you will need to also refer to the Addendum video.
http://eshop.macsales.com/item/OWC/DIYIMM11D2/
Some users have reported problems with an SSD being the boot drive in the upper bay. They have not reported problems with a HD boot from either bay To avoid the problem I would move the HD (if it is in the lower bay) to the upper bay and install the SSD in the lower bay.
I allocated 64 GB for Win 7 in Parallels abd 4 GB Of 16 installed). You can change them later after you install so it is not that importent what you specify initially.
For TRIM see:

How do i reload OS X Server on Mac Mini, App store says installed but no reset or reload, system tells me to reinstall

how do i reload OS X Server on Mac Mini, App store says installed but no reset or reload, system tells me to reinstall?

Reboot holding down the Command and R keys. This will get you in to the Recovery partition. From there you can reinstall the entire OS. Please note, Server.app will not be included in the reinstall. You will need to log into your App store account to download it.

Internal HD on mac mini not well... need to boot in Single User Mode

Internal HD on mac mini not well... need to boot in Single User Mode.
I only have a Bluetooth Keyboard and Bluetooth Mouse so when I try to boot in Single User Mode (to do the /sbin/fsck hard drive fix thing) it doesn't see the Bluetooth Keyboard. What's the solution?
I also used SuperDuper to use as a boot drive but it won't unmount my internal HD. arghh..
Help

I have a corrupt drive and was unable to repair all the errors after booting from OS X installer disk and choosing Disk Utility...
I followed the "boot into single user mode" instructions hoping to complete my repair with fsck, however once I got to the localhost:/ root# prompt, my keyboard seemed to be unrecognized!
I tried 3 different USB keyboards - original Apple USB keyboard, Kensington Mac USB keyboard and an old SGI USB windows keyboard. All were able to enter the apple-S key to get into single user mode but NONE of them were able to type any commands whatsoever.....
I'm thinking my only option is to boot the mini as a target drive off my laptop and try to backup my 30GB of music and photos before wiping the drive...
2nd option might be to try Disk Warrior for $79??
Anyone else have ideas for me?

Mac Mini fresh 10.4 install - can't install bundled applications.

Okay so I just got my first Mac last week . It's a Mac mini 1.83 Core 2 Duo. It came with Tiger and ILife bundle, and a Leopard upgrade dvd.
I installed Leopard (erasing the original install) only to find that there is no iLife on it. I tried installing the bundled apps onto leopard using the original dvd's and that kept failing as well.
Now I'm trying to reinstall the OS X 10.4 + bundle (my original grey cds) so that i can upgrade to Leopard and keep the iLife bundle.
1. I erased the drive using disk utility on the Tiger cd's, and reinstalled Tiger along with the bundled apps. This didnt work completely - when it got to the bundled apps, it failed at the end saying install failed - try again. And it doesnt even give me an option to exit - just keep trying the install of disc 2 again and again. I tried this another time and it still didnt work.
2. I tried again from scratch- erasing the drive and reinstalling - this time installing only Tiger without the bundled apps. Tiger installed ok. I did a software update, then tried installing the bundled apps manually. Still it wont install them.
3. I tried installing bundled apps again after #2 failed - still no luck.
The install log says it failed when doing pre-flight check of iDVD. But the second time it failed it was doing a pre-flight check of iPhoto.
Does anyone have any ideas what I could be doing wrong with this thing? I've erased and installed this thing like 6 times already and it still wont do a proper install of the bundled apps!

Ah, apologies, for some reason I had thought you were in the UK. Apple Canada don't have quite the same issues of remoteness as Apple UK, so it surprises me further that you have suffered the support issues you have. One of what I would have always considered to be Apple's deficiencies however is that they generally channel their feedback and support via stores and phone contact, rather than providing email or internal corporate contact details. It makes it easy to call for help when needed, but not so easy to let them know what you think about the help you actually received. Calling the phone support line and asking for the call to be escalated up is probably the best approach, and if nothing else will give a better insight, since in my experience most of the customer support calls are handled rather more constructively than your experience so far would suggest.
Ultimately, only you know exactly what your objective is of course, but if you had reached the point that it was clear a Mac was the right system to buy for your parents, then I suspect that you're right, your objective would not be likely to be best served by returning this system and switching to something else. As such, the short-term frustration of having to deal with this now, but having a working and fully installed mini for them to use in the longer term would perhaps be better than extricating yourself from the frustration now and thus gaining in the short term, only to have your parents cope with a less ideal system, even one where instead of an emphasis on ease of use, they would need to focus rather more on security, virus protects etc in a Windows system.
It does, of course, leave a bit of a bitter taste if you were to keep the mini and effectively let Apple get away with such poor support. The only problem is, however, that reacting to it by returning the system hurts them very little, and in reality perhaps does more to impede your own objectives.
Whatever you decide, bear in mind that however poor some of the staffers on the phone can be at times, and how unhelpful some of the staff in the stores, Apple Discussions here is often a very good way to get help and support from people who are just ordinary Apple users. We're not always able to help - there are some questions asked here which don't get responses, but by far and away most do! There are also Mac User Groups in many areas where help can be found (and often a helping hand and a copy of an install disc to help alleviate the frustration of waiting on Apple to post one out). Local Apple stores typically also have 'genuis' bars where help can be obtained, even for equipment out of warranty, and while the quality of support isn't always what one might hope for, it can be truly excellent.
In the end of course the fact that the quality of Apple support may be typically rather better than you have experienced, it doesn't excuse the bad experiences. Often, however, their products go a long way to make up for it!
Best wishes in whatever you choose to do.

Mac Mini Server freezing in install when choosing PPPoE

I have a Mac Mini Server and when I go through the installation procedure and choose the connect PPPoE from the Network settings, the installation hangs every time.
I have already tried several clean installs from the Mac Mini Server disc to no avail.
Suggestions?
Thank You.

What part of the install process do you have trouble with? I'm assuming, and I think Tony did as well, you're talking about the server setup assistant that launches once the OS is installed. Naming your server/domain is a critical part of setup, as is DNS. If you put faulty configs in during setup, or try to setup services before DNS is working, you'll run into trouble - so please include whatever you're trying to do - if you're new to servers, most everybody around here will be helpful or at least understanding.
In any event there's a great tutorial at
http://www.wazmac.com/serversnetwork/fileservers/osxserversetup/index.htm
While I agree with Tony that PPPoE isn't the best bet, you ought to be able to make it work - but you will need a static IP for your server. Best bet is probably to make it a static IP on your LAN using NAT and let your router/firewall have the live IP. But more info is always better - what are you trying to setup and what other equipment/network stuff is already going on? There are a lot of ways to setup a server and to setup a network, and there is certainly no one correct solution. Somebody smart (like Tony) may be able to give you a lot more options with more details. I'll try too, but I'm far from the most knowledgeable person around these parts.
Another thought - if you're not using the advanced server, I believe you need DNS set up beforehand somewhere - if you just enter your ISP's DNS server info, it won;t have any records for your server. The Wazmac setup notes will walk you through setting up your own DNS for your LAN and using your ISP's DNS for everything on the WAN side.

Mac mini with 10.6 installed - dual boot 10.8?

Hi all
I have an a Mac mini with 10.6.8 installed (think it came with 10.5) and would like to buy Mountain Lion from the Apple Store and install it as a dual boot setup. I think the hardware is too old for 10.10 (although it does give me the option to download it from the App store). I would like to keep my existing install and install 10.8 either alongside 10.6 or on a separate partition. Couple of questions;
Can I shrink the partition that contains my existing 10.6 install (there is plenty of space on the disk), create another partition and install 10.8 onto it?
Failing that can I install 10.8 alongside 10.6 on the same partition (like we used to do for OS9 and OSX)?
For 10.8 I will be receiving a "content code" for the Mac App Store - once I download the files and start the install presumably the Mac will restart and I will get access to the usual install utilities (without the OS running)?
Many thanks for any help.

If your computer will run Mountain Lion, it will run Yosemite.
1. Yes.
2. I would go with 2 partitions.
Yes.
Check that your computer is compatible with Mountain Lion/Mavericks/Yosemite.
To check the model number hold down the option/alt key, go to the Apple menu and select System Information.
Mac mini (Early 2009 or newer) model number 3,1 or higher
Your Mac needs:
OS X v10.6.8 or OS X Lion already installed
2 GB or more of memory (More is better - 4 GB minimum seems to be the consensus)
8 GB or more of available space
Check to make sure your applications are compatible. PowerPC applications are no longer supported after 10.6.
Application Compatibility
Applications Compatibility (2)
Do a backup before installing.

Mac mini slow startup since installing yosemite

I have a late 2012 mac mini and before installing Yosemite it would take just a few seconds to start up when I turned it on. Now since installing Yosemite it is a lot slower to start up, and i get a "progress bar" when I turn it on, which I never had when running Mavericks. Any ideas how to fix this?

Imac G5 not reconizing Leopard install, Need help diagnosing.

Hello, my names Jarid and my problem is the following;
*_Using Now_*
I am currently on my macbook pro 10.6.5 snow leopard OS.
Background
I got an Imac for Christmas from my fathers Friend, the friend recently moved to china and left it behind.
this G5 (2 gigs of ram, 1.8 ghz processor) had tiger installed on it but while i have switched to mac about 6 months ago, I have a strong background in windows and learning as i go on mac. I wanted to install leopard on this G5 because my Macbook was leopard when i received it so i wanted to upgrade for familiarity.
One strange thing right before i tried to install was i tried to install new applications and they would just open up really quick on the dock then disappear and not work. Firefox worked, as well as itunes ect but they were already installed..(I think i may have DL the wrong OS support?? i do not know)
While installing a new program it actually started to run; i tried to DL a tiger version of an app to see if i might have been using the wrong instal(this is where i thought i was installing the wrong OS app maybe?).
The comp sort of froze, so i restarted holding down the power and got the purple folder with the blinking '?'. I figured i could just install leopard and fix what appeared to be "corrupt system/32 boot"(windows) I Bought Leopard @ best buy 10.5 and put the disk in and pressed "c".
Problem
It started fine until i had to pick a disc to choose from, there was no drive. I opened disk utility and I THINK it had 1 partition listed and the disk drive. I then proceeded to "erase" the drive considering it was already missing files anyways. I remember something though like I created "journalism" or something and the drive now showed in the "where do you want to install". I chose the only drive (hard drive 250g). I watched it for 40 minutes and then went and UG my leopard to snow leopard. When I finished, I figured my G5 would be done however the screen did not light when I used the mouse or keyboard. I shut it off by holding the power button. now I still get the purple folder with the '?' mark. When i use the disc to boot I cant see the drive again but this time all that is in the disk utility is a pic of a cd (guessing my boot disc) even though i saw the HD there 2 hours ago...
*_Things I Have Tried_*
1. I tried using terminal in the start up with the disc to find the drive, but it listed disc 0 1 2 3 with like 500 mb, I think 2 "X" amount of kb, lastly like one 7 GB and that was it no big HD listed?
2. I tried Holding "option" and try finding the drive but nothing showed up, I took the installation disc out at this point.
_*+Additional info+*_
I know Windows Xp extremely well but not mac too much and **everything I've done was done from what I've been reading offline**. Any help would be greatly appreciated. +I am still new to mac+ so if it is not windows-type ideology please explain A little more in depth for me please, thank you.

You might try resetting the SMU:
1. Shut down the computer.
2. Unplug the computer's power cord.
3. Press and hold the power button for 5 seconds.
4. Release the power button.
5. Attach the computers power cable.
6. Press the power button to turn on the computer.
Or reseting the PRAM.
You can check the drive using Apple Hardware Test, which should be on one of your install discs, hold down the D when booting to it.
Did you wipe the drive when you were running from the install disc?
If the install disc works, try using Disk Utility to repair your drive, but it sounds as if the hard drive has failed.
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk.
Let us know how you make out,

Mac mini 10.4 will not start help me please!!!

Please help somebody. I've tried to turn my mac mini on today and it's suddenly decided that it doesn't want to play any more!
I keep getting the grey screen and a message coming up saying that i need to reset.
I have followed all the options of taking out printers etc, safe booting, resetting PRAM etc etc.
All I have left to try now is re installing from the software CDs.
But that's where my problem gets worse. I've been pulling my house apart for hours but cannot find my CDs anywhere.
Does anybody now how or where I could get replacement tiger CDs?
Thanks for Reading.

While performing disk maintenance is advised from the boot install discs of
the correct version Mac OS X your computer has installed, it may be possible
to resolve a few startup issues and perform disk maintenance with Disk Utility
and also attempt some repairs with a command known as fsck.
The latter does not require the boot disc version of Disk Utility to perform a
few basic functions, it does however require using a single-user startup.
In Tiger 10.4.x, it is always better to be able to use the correct Disk Utility on
the 10.4 booted installer disc; since fsck is not as thorough.
"Resolve startup issues and perform disk maintenance with Disk Utility & fsck"
http://support.apple.com/kb/TS1417 - an Apple Support knowledgebase article.
This won't fix disk drive corruption, or directory failures; other disk utilities
are good at doing that; and the installer disc's Disk Utility is a primary tool.
There are third-party disk utilities that can do several specific things the
included Disk Utility on bootable install disc generally won't.
Good luck & happy computing!
