2006 Intel Mac mini starts to load then turns off and sometime a kernel panic warning will appear

Mac mini starts then powers off before loading osx and sometimes gives a kernel panic warning

Tough without the Install disc, but some things to try...
Does it boot to Single User Mode, CMD+s keys at bootup, if so try...
/sbin/fsck -fy
Repeat until it shows no errors fixed.
(Space between fsck AND -fy important).

Mac book starts to boot, then turns off

I have Mac Book Pro (13", Yr2011) which will not boot. It has a 1TB HD which has been partitioned for Mt Lion (primary) and Snow Leopard. The computer has worked fine in this configuration. For about 6 wks, the computer was not used and apparently the battery charge depleted to zero. When an attempt was made to use the computer with battery only, the screen was just light gray with a circular wait icon. After several minutes with no change, the battery was noted to be discharged. A charger was connected, but there was no change in the screen. The computer was then turned off and left to fully charge. On first attempt to turn on, the computer did come to life. However, when attempting to Update software, it displayed No Internect connection - even though it was connected by ethernet. The computer was power cycled, however the screen then again only showed light gray with wait icon. Now when attempting to boot, the screen shows light gray, circular wait icon & horizontal bar graph indicating something is loading. After about several minutes, the bar graph fills & disappears, however, the screen remains light gray with wait icon - indefinitely. On a few attempts, the computer and screen simply turned off after about 30secs.
If I hold the Option key while powering on, then the Mac does boot ok to Snow Leopard. Apparently, the Mt Lion side of the HD was corrupted during the low battery boot appempt. The last time I backup MtLion was several months ago, so if I prefer not to reformat and reload from scratch.
Since the Mac did boot up once, I'm wondering if there is a way to recover without having to reformat and start again.

HT4904 I need to repair my start up disc so I have to start up from installation disc. In doing so, my computer restarts, I hear the mac sound, then a grey screen and then turns off and goes on in this cycle endlessly. Why can't I restart from disc?

when i active my mac pro all i get is a white screen and it loading and when it fully load its turn off , and it keep on doing the same thing for hours

Hi Shahenaz,
It's a little difficult to understand exactly what's going on with your mac based on the description you gave. Is there anything else you could add? Is it stuck in a reboot loop? Or is it just showing a white screen forever?
I had pretty much the same problem a few days ago, and was worried my mac was screwed permanently, but I got it fixed up no problem!
Follow these steps to try and troubleshoot/fix the problem.
1. Boot into OSX Recovery Mode
First, turn off your Mac. If it isn't responding, or is stuck in a reboot loop, just hold down the power button until it turns off, and you hear the fans stop. Then boot it while holding the Command and R keys. If it successfully boots into OSX Recovery Mode, continue with this step. If not, skip to step two. (My Mac couldn't successfully boot into the recovery mode, so I had to go to step 2)
Select "Disk Utility" from the list of options, and find your built in hard drive from the list on the left. Usually there are two listings/names for your drive. The first should be something like "500GB longchainoflettersnumbers Media". Then the one below will be a little easier on the eyes, named Macintosh HD, if you haven't changed its name. That's the one you want, click it.
Now go to the "First Aid" tab. Click on the "Verify Disk" button in the bottom right corner, and let it do its thing. Once that's done, hit repair disk, also in the bottom right corner. If your disk is corrupted, you may need to run the repair process several times, before it comes up completely clean.
Once this is done, select Shut Down from the Apple menu and, once your Mac is completely off, turn it back on like normal. If it works, great. If not, proceed to step two.
2. SafeBoot
Sometimes, when a mac is acting up and doesn't want to start, all it takes is a safe boot, followed by a regular restart. Or maybe you recently installed a program that either has malicious or errored coding that's causing your troubles. This is where Safe Boot comes in.
Turn off your mac, and reboot it while holding Shift. (If you want to see the process that's going on in the background, boot while holding Shift, Command, and V. This will enter something called Verbose Mode).
If it boots successfully into Safe Mode, great. If you believe that there's a particular program that you recently downloaded that might be causing your trouble, now's the time to delete it. If not, just reboot normally and see if it works! If it doesn't, or if your Mac didn't even Safe Boot like mine, proceed to step 3.
3. Fsck!
For this step, you're going to be booting your mac into Single User Mode. I'm not going to go into details as to what this step does, but it works for some people. Here are the steps.
Turn off your mac, and reboot it while holding Command and S. The screen should go black, and you'll see some white text run across the screen, wait a few seconds, until you see the command prompt. Now type
fsck -fy
and hit the Enter key. This will run a series of system checks, which could take a few minutes. Be patient on this part. Once it's done, it will show one of two messages:
1. "The volume (your Mac) appears to be OK
or
2. "File System Was Modified"
If you got message 1, type reboot and press Return. Hopefully your computer works after this - if not, proceed to step 4.
If you got message 2, run the same command again until you get message 1. If it doesn't seem to be working, turn off your system and proceed to step 4.
If you couldn't even boot into Single User Mode in the first place (like me), go to step 4 anyways.
Step 4: Reset the NVRAM
The NVRAM is another kind of RAM that stores data like the computer volume you had set before you turned it off, or the screen brightness, resolution etc. This memory is saved, unlike with regular RAM. Resetting it isn't harmful to your system, it will just put your screen brightness, volume, etc. to defaults.
Turn off your Mac, and reboot while holding Command, Option, P, and R, and continue holding them down until you hear the computer restart again.
I can't really explain why to do this step, I just know it works for some people, and seems to be what unbricked my MacBook Pro. If none of these steps, fixed your Mac, well the situation is looking pretty grim. Try setting up a meeting with a Mac Genius at your local Apple store. However, I know that many other people with these symptoms ended up having a logic board failure. Apple can swap out your logic board for a new one, but the price is pretty hefty, somewhere around $300 I believe.
Well I wish you luck, I hope this helped you!

Reinstall OS X, either from disc or a recovery partition. You don't mention which version of OS X you're running so I don't know which it will be.

New Intel Mac Mini Start-up Problems

I've recently purchased a new Intel Mac Mini (my first Mac after switching from a PC). Several times (probably once a day), the mac mini won't start-up.
I've noticed it happens after I've used iPhoto or iDVD. The mini becomes busy and performance seems to slow. After the software has finished its task, I can exit the application fine and shut down the mini.
When I then go to boot the mini, the little blue light comes up, but nothing else happens. It's almost as though it's in sleep mode (which it isn't). I've tried different ways to wake it using the keyboard, mouse and start button, but nothing.
The Mac Mini will only start-up again if it is unplugged from the mains and left for several minutes.
Has anyone else had this problem? Is there something I'm doing wrong that my lack of Mac knowledge may not be aware of?
Any help would be appreciated.
Thanks

I have been frustrated by the same issue. My (admittedly non-professional) diagnosis is that the problem is related to heat build up. I am able to boot normally only after forcing a hard shut down and waiting for "a while" (5 minutes is not enough, 30 minutes does the trick). Thus my hypothesis that an appropriate cooling down period is needed.
Any similar thoughts? I'm calling Apple today...

Mac mini (late 2014) display Flicking/goes Off and On

Hi everyone!
Well.. i can say that, this is my first Mac computer and i already have problems. I have read a lots of comments and i have seen that many people experienced this problem with Mac mini, like display corruption, not property colors, flicking, display goes off and back on... or just standing on sleep and not turning on. (like Mac mini 2012 or 2011.. i have read about same issue..) so whats really happen?
So, from the peoples comments i tried possible solutions:
SMC Reset
I have Reinstalled the OS X Yosemite (complete HDD format)
I have changed the cable
(Nothing works)
Some detail about my connection:
I have Mac mini (late 2014) i5 2,6GHz dual-core, 8GB ram, Iris Graphics (Intel), 1TB HDD
I have connect it via miniDP to DP > to > Dell UltraSharp U2713HM
My following issue:
-Screen goes Off and On without reason (mostly happens when i connect my iPhone i have noticed, or maybe just impression..)
-Screen goes to Sleep without reason while i'm on computer (this normally happens after a few off and on screen flickers)
-Image corruption/distortion (after this display goes off and on, or just remaining on sleep.. like not detected
I hope someone can help me with this problem, i just bought it one week ago and i don't know what should i do, because as well i have read that even i'll change it, it can have the same problem.
Waiting or a response,
Best regards.

Update: I'm coming back with a possible tip for fixing this issue (I hope Apple Stuff will notice this.)
So, how i said in the previews message.. the Image corruption / and going Off and On the display happens mostly when i'm connecting the iPhone. Theory tested a few times, and take a guess.. it's true.
When i'm connecting the iPhone, the monitor goes crazy.. for some seconds, turning off and on.. and sometimes Image corruption, then coming back like nothing happened. Because i found out this, i was making more tests with the iPhone.
First, erasing the disk and reinstall the OS X again. Everything worked perfectly, until i was connecting the iPhone. I got directly Image corruption and Screen goes Off and On a several times. After this is happening, and you'll unplug the iPhone and put it again, you may not receive again Image corruption or Screen to go Off and On, but after a restart when you'll connect it again, you will receive almost everytime.
So.. after this, i was testing further. I have Paired my iPhone with iMessage and FaceTime, to see if can be a possible issue there also. True again!
Receiving messages from iPhone to Mac / Sometimes display goes Off and On
Receiving a Call via FaceTime to Mac (from your iPhone carrier) / Image corruption / Screen Off and On
After a day of test, i have realise where is the problem. "iPhone connection/Mac"
So, the cable it's good (connection miniDP to DP), by Surfing and by running other Apps i have no problem (at least until now), the only problem what cause the Image corruption and Screen Off/On for several times, it is only because of the connection with the iPhone.
I hope is someone there from Apple Stuff that will take this as notice to solve this problem. Because it is 99% software problem, and i hope it will appear soon enough an Update/Fix.
Thank you!

IPod Touch 2nd Gen (8gb) Loads to Apple symbol, then turns off, and repeats.

Okay so I went into my settings to do a reset on the iPod Touch. I did the reset and now all the iPod does is load the the black screen with the Apple symbol, stay on for a few minutes, turn off, and repeat.
When I connect the iPod to ANY computer with iTunes, it doesn't even show the iPod as connected. I honestly do not know what to do.
Does anyone have a solution on how to fix this?

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.
Apple Retail Store - Genius Bar
Did you by chance not have the iPod connected to a charging source during the erase? It can take hours ao a 1G and 2G iPod and fully drain the battery before it is complete.

IPhone 4 screen flickering then turning off and when i try to turn it back on it either works or I get a white or purple screen. When i turn it off it doesn't turn back one

Ok so this started around a week ago. I got home one afternoon put my phone down went back to it and pressed the home button and it seemed that it turned itself off so I tried turning back on, didn't work so I hooked it up to my laptop tried turning it on again it came on but I got a WHITE screen. So after that I decided to leave it for a bit I went to it after it started working fine...until 4 days later. I was on instagram and all of a sudden the screen starts flickering like crazy and then it turned itself off, I did what i did last time and just left it for a bit it came back on working fine. And then about 2 days ago I was listening to music and the screen froze then started flickering (getting quite annoyed at this stage) and then turned off, this time I tried turning it back on straight away only this time it worked. And that brings us to this morning, i was on facebook and about 5 minutes later it starts flickering and freezing once again and then turned itself off. So i hooked it up to my laptop I then got it to turn on for like 6 seconds then the screen started to dim and turned off. That brings us up to now about 10 minutes ago i tried turning it on, it turned on but I got a PURPLE screen and it just stayed like that until i turned it off. Does anybody have any idea what is going on? I think its the screen itself but i'm probably wrong. All help is appreciated.

I am also having the same problem.. Its too much annoying and its unfortunate nobody at apple support has anyclue of what is happening?
... This is happening almost most of the time keeping my phone down most of the times.

My Mac mini starts up with a black screen and white writing.

Okay basically I purchased a Mac mini (Intel Core 2 Duo 1.8GHZ 1GB RAM model) in Feburay 2008, and in June 2008 i decieded to bring it to a store to get it upgraded to 2GB. At the store the guys told me my Mac mini wouldnt accept 2GB, they reckon it was 'cause of the logic board. So they put a new one in and was able to succesfully install 2GB.
Since that day my Mac mini stopped starting up with the apple logo. Now it starts up with the white/greyish background without the apple logo, then goes to a black screen and just runs pass loads of white text then its ready to use with no problems. It does this all the time.
I've read a little about the Kernal Panic and looked at pictures of it, but what I have doesn't look like the kernal panic pictures i'm seeing.
So i am writing this pose to find out whats wrong with my Mac mini, can anyone help me?
Oh, I nearly forgot. When i turn the Mac mini off it does the same black screen with white text stuff before fully shutting down.

Restart the computer with the Option, Command, P, and R keys held down, and release them when you hear the second startup chime; this clears a setting which causes it to start up into verbose mode each time.
