Mac Mini crashes when I attempt to boot to OS Disc

Can't reinstall/reformat. System crashes when I try to reboot with the OS disc in. Before that, when i started the computer, the pinwheel kept spinning and I had to boot in safe mode and run Disk repair. Then it booted fine. But my iMovie project keeps losing the sounds I put in and unable to control the volume of some sounds i put into the movie project. Could this be my hard drive is dying?

Hi Clifford,
Just asking, is the OSX Install Disc the exact one that came with that Mac?
Not that you'd want to use it if your on 10.8.5 though!
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.
If that doesn't help Reinstall the OS.

Mac mini crashing when booting up

Hi, does anyone know why the mac mini crashes at bootup. it gets teh strart up ping, then the loading screen, then the harddrive turns off. any ideas why this is happening

I had a similar problem recently, my mini froze during a backup, held the power button down left it for a few mins and rebooted, only got the grey screen with apple logo and the spinning gear and that was it, could not get past that so I installed OS X on an external drive, the internal HDD took upto 10 mins to mount then vanished copletely a day or so later, in the mean time the optical drive stopped working as well!!, took it to the Apple store who thought it ws a dodgy interconnect board, but they called yesterday to say that both the hard drive and optical have conked out, and that the machine was packed full of dust, and possibly caused everything to overheat!! (am allergic to dust so keep my flat quite clean!!), to replace both costs about the same as a new machine so not worth it!. So off to collect it today and buy a new one. Have had the machine barely 2 years! and thought it would outlive my Dell PC!

Mac Mini crashes when HDMI-connected AV receiver powered off

This issue concerns a Mac Mini, mid 2011, running Yosemite. It is connected to a Yamaha AV receiver using HDMI and under normal circumstances works normally. However, whenever I power off the AV receiver, the Mac Mini crashes (spontaneously restarts).
I can't find any trace of a kernel panic, and there is no message after startup to say that the system has restarted unexpectedly.
For example, the system log from last night shows that is was performing a backup, and then there's the boot message at the time I shut the AV receiver down:
1/24/15 10:18:29.000 PM kernel[0]: hfs: mounted Recovery HD on device disk0s3

Output parameters from ASL Module "com.apple.asl" override any specified in ASL Module "com.apple.authd".
I have swapped out the HDMI cable in case it is faulty, but this has not changed anything. This issue is easily reproducible but I haven't been able to find any possible solutions. It started after the Yosemite upgrade. Also, the AV receiver need not be displaying the Mac Mini video for this to occur. It will crash regardless of what channel the receiver is showing.
Any help would be much appreciated!

I have a similar issue after recently buying a receiver (Sony STR-DN1050) and wiring my mac mini through it.
Some observations that seems to be linked.
1. When I power up the receiver with another hdmi input than the mac mini, the mac mini switches fast between displays, from the TV name to unknown (observed through Remote Desktop), and sometimes log out the user.
2. Then, when switching to the mac mini hdmi input, everything works fine, as the mac will recognise the TV.
3. When switching off the receiver, the remote desktop disconnects and usually the mac mini will log off user or restart- not sure which.
Edit: Right now, when I powered off the receiver, the mac stayed on... no idea why, as it usually disconnects as mentioned above.
Edit2: As I look in the Display settings, the mac now recognizes my receiver as Display when it is turned off, presumably because I turned off HDMI pass-through on the receiver settings.
However, I still have problem 1 above: When I turn on the receiver with any other input than the Mac Mini, the mac will start switching displays and log out the user.

Mac Mini crashes when exporting imovie projects

Hi.
When I try to export imovie projects, my Mac Mini crashes. Not ever, just every two or three times.
My system is 10.6.7 and imovie is 11. Can anyone help me? Thanks, I apologize for my bad English

Thank you, I'll try!
I hope you're right, because is boring to see out of the blue all the screen getting grey and the window that invites you to reboot, without hope... It happens, for example, after two or three succesful exporting projects, then I reboot and go on for another two or three projects and then again... I'm afraid it's a RAM problem, but I'll try to update system and software.
Thank you again

Mac Mini crashes when connected to USB mouse!

This problem just happened all of the sudden--I came into my office a few days ago and there was the multi-lingual screen of death telling me I needed to restart my computer. Tried numerous times, no success--same message.
Took Mac Mini to Genius Bar--they said it checked out just fine.
Brought it home, plugged everything in--same problem!
Started eliminating USB and Firewire items that I was connecting to it. Narrowed it down to my Verbatim USB wireless mouse. When I disconnected it, the computer booted fine. However, can't navigate anywhere w/o a mouse, so I figured my solution was to just go buy a wired USB mouse.
Bought wired USB mouse. Same crashes! My computer will not boot with any USB mouse connected and when I connect a mouse after it is booted, it crashes the moment the mouse is connected.
Even if there is something I could install or uninstall, I can't do it because I have no navigation w/o a mouse!
Error messages on screen of death have to do with "kernels" and what not--again, if it was something I could replace/reinstall that would be great, but how can I do anything w/o a mouse?
Please help!!!
Thanks,
Phil

I have three 2008 model Mac minis, each with verbatim mice. Luckily one hasn't been upgraded to 10.6.8 because I'd be without a working desktop machine.
The 2010 Mac mini doesn't have this problem.
So far I've tried four different USB mice and all of them lock up the machine, even in safe mode.
I can't afford to go and buy three apple Bluetooth mice - it's the only way I can use these machines.
I hate downgrading machines, so I'm hoping apple supplies a patch soon.

Mac Mini crashes when airport is turned on

Hi
I have a mack mini from 2008 running leopard 10.5.7. It just crashed/hung the other day for no reason so i wipped the HD and reinstalled leopard after a long process of illimination. I had it working in safe mode prior to reinstall with no problems so i assumed this was a software problem. So after the reinstall everything works fine except for one thing. When i turn on airport it does exactly the same thing...just crashes and hangs. I have run out of ideas as to how to correct he issue. It's airport for sure and I have no idea why it's happening. Any ideas would be most welcome.
thanks

Thank you for the reply...I had already done the hardware test....but since posting if discovered this in an article and it works.
SOOOOO...here what this is....the airport tcpip settings(IPv6) needs to be switched off...it's as simple as that...
System preferences, Network, Airport, TCP/IP, Configure IPv6, SET IT TO OFF...and all good...
many thanks

Why Does My Mac Mini Crash So Much?

I have a Quicksilver PowerMac and a Mac Mini, and they both have (substantially) the same software configuration - the latest Apple software. The Quicksilver is solid as a rock. It never crashes.
The Mac Mini crashes frequently - I'd say an average of twice a day. Many different applications are in the foreground when it happens, but it is usually Safari. I suspect it might have to do with the memory that I substituted. I put in a 1 GB memory module - Kensington from Fry's. Memory tests say it is fine.
How can I track this down? Does Apple help?
Brian

First off, I would like to thank you all for attempting to help me out.
Next, I'd like to correct my original message. The memory is "Kingston", not "Kensington". (I was working from memory, and that doesn't always work so well.)
I think I'm going to go with the suggestion to swap the memory out and observe what happens. I was hoping that someone would come up with a method of finding a "smoking gun" - something that would positively identify the memory as the culprit or eliminate it as the problem. I guess it doesn't work that way. Last night (all night long), I ran REMBER, a GUI "wrapper" for the "memtest" command line program, and it found nothing. I suspect I can run it for a weekend and get the same level of information.
I hope Andy's right about his "no quibble" comment. I called Kingston, and when I told them that I had the 1 GB PC3200 DDR, he informed me that the Mini was spec'ed for the PC2700 memory. It's my understanding that both of these are supposed to work (the 3200 slows down to 2700), but I can see the beginnings of quibbling.

Hi, Hugo,
In similar cases it helped to remove the GarageBand "Preferences" file from the User Library.
Open the folder
your home folder > Library > Preferences
and move the file "com.apple.garageband.plist" to the Desktop.
Then try again to launch GarageBand.

PSE 11 crashes when I attempt to add a new catalog

PSE 11 crashes when I attempt to add a new catalog to those that already exist. No programs are running that might conflict with Organizer, and I can run other functions such as downloading photos from my camera. As soon as I attempt to add a new sub-catalog to an existing major catalog, the program crashes. I'm using Windows 7, and have tried various compatibilities, but none solves the problem. Any ideas?

How do you attempt to 'add a new catalog' or a new 'sub-catalog' ?
There are no such things as 'sub-catalogs' or catalogs included in catalog.
Catalogs are totally independent storing systems, they ignore what is managed in other catalogs.That's why it is recommended to have only one catalog, unless you have a good reason to create several ones because they are totally independent by nature (home vs professional for instance).
You can create several levels of albums, of tags categories, but not with catalogs.

I am set up mac mini and when I test the mail server by sending a mail from administrator to administrator I get the error message 'Diagnostic-Code: X-Postfix; connect to 127.0.0.1[127.0.0.1]:10024: Connection refused'. Can any one suggest a solution

Thanks. Where could I possibly look for a firewall rule. I knowingly did not creat any. My system has internet coming to a Modem which then is connected to a wireless router. I have computers connecting to the router through cable as well as wireless. One of these computers has been our mailserver using Mercury and Pegasus and that computer has a static IP address. The Mac Mini also has been assigned a different srtatic IP address. I have only set up user account, none of them an email account as I initially expect them to receive only internal mails. Is it necessary that I must set up an email id for each user while setting up the user account. My server id is server.local. So would the email id for local users be [email protected]?

Opera mini crashes when scrolling

ANYONE ELSE HAVE AN ISSUE WITH OPERA MINI CRASHING WHEN SCROLLING? ANY FIX SUGGESTIONS? SEESM TO EFFECT THE 5800 TO.

LOVE my 5700 ExpressMusic, HATED my N97, Salivating for a N900
Like my post? Kudo me Please!

The only Opera Mini crash that I've seen was one that reported an "Out of Memory" error just before it exited.
I had left the Web Browser open (used it to find and load Opera Mini) and had forgotten to close it.
Since then I've had no problems with it, but then I mainly use it for RSS feeds as it is friendlier than the Web Browser's RSS feed reader.
