Mac mini start up problems

good day! i have a problem with my mac mini and it wont start up i already follow the instructions at the manual but still problem occurs.. pls. help. tnx happy new year!

Hello Jaun,
Is this what you tried?
"Try Disk Utility
1. Insert the Mac OS X Install disc, 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 at top of the screen. (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. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
If 10.7.0 or later...
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.

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 Start Up problem?

I am having a start up problem with my powerpc mac mini which runs on max os x 10.4.11. About a week ago there was one day where it would not power on at all so I waited a day and it turned on again and was fine again. However today, when I connected a new WD hard drive to back-up my files, the computer froze. I assumed that was normal since this has happened every now again, I guess its because it doesn't have a lot of RAM. So i had to turn it off by holding down the power button at the back. I removed the hard drive then turned the mac mini on again but now all I see is a flashing folder which alternates between something that looks like finder and a question mark. Basically the folder looks like this: http://www.mac-forums.com/forums/apple-desktops/164988-folder-flashes-question-m ark.html
According to those people, it means that the mac mini doesn't have an operating system installed but that is impossible for me since i've been using this mac mini for 7 years. I've tried starting up in safe mode but that won't work. When I try to start up using the start up menu, I see no hard drive icon to select. All i see in this menu is an arrow that resembles the "undo" arrow in word and an arrow pointing to the right. I haven't tried re-installing the software that came with the mac since that might (or will) erase all my files.
So any ideas on what could be wrong? Has my mac mini given out because it's old? Is there something wrong with the hard drive? Thanks in advance for your answers.

Hello Jay,
The drive is either dead, dying, or having severe problems.
See if Disk Utility sees it at all.

Mac Mini with Major Problems

I'll try to make this short, but it is a looonngg problem.
About one month ago my Mac Mini began having problems when I boot up. The computer would freeze on the opening page where I put in my password. My wireless keyboard and trackpad would not work. This would be interminent at first but progressively got worse.
I spent hours on phone tech support. Finally realizing that would not help I drove the 100 mile round trip to the local Apple store for a Genius bar appointment.
The first appointment (there have been 5 - meaning 500 miles) resulted in them doing a clean install of Lion. I took the computer back to the office and guess what, the same problem.
I drove back to the Apple store, the Genius did some more work and proclaimed it fixed. It was, for about 3 days when everything started again.
More time now on tech support. One more trip to the Apple store.
This time they kept the Mac Mini for about 4 days are replaced the logic/mother board.
I got it back to the office on Thursday. Everthing works great.
Until today. I boot the computer, it gets to the screen that has the apple on it - then nothing.
I manually power it down and reboot. Same thing.
I've set up ANOTHER appointment at the Genius bar tomorrow.
My question: can I demand that they replace this machine. Between work and home I have 2 Mac Mini's, a Macbook Pro, a Macbook Air and 2 iPhones. I've never had this type of problem. I'm really tired of this.
I purchased this in February so it is in warranty.
Thanks

Excellent new, sorry you had so much trouble on the way. And yes, Apple Stores are awesome!

Mac mini start up shut down code

I appreciate the two responses, from '300Tech' and TITOUMAX to my original question.
I was reluctant to take the "sudo halt" terminal suggestion since a warning loomed over the danger of losing data.
I was unable to post a copy of the code sequences suggested by TITOMAX since the problem was solved by the time I saw his post.
I received an answer from Apple.
I was able to halt display of start up and shut down code by shutting the Mac mini down and starting the machine while holding down "cmd option PR" keys until the computer gave the normal start sound followed by a repeat of the start sound. This procedure led to a normal start up process and also a normal shut down process without the display of the "start up code" during start up or the display of the "shut down code" during shut down.
By the way, holding down the "cmd option R" keys with my left hand while pressing the Mac mini start button with my right hand and quickly getting my right hand in place to hold the "P" key was tricky, but only took two tries to achieve success.
I was concerned that the display of those lines of code was an indicator of an impending problem. It turned out to be an unintended feature following replacement of the logic board.
By the way, Apple Care has been wortwhile for me.

Thanks for the report, that's called a PRAM reset, CMD+Option+p+r...

2014 mac mini dual monitor problem

I just brought a mac mini (Late 2014) i have two displays monitors connected, one HDMI to DVI. and one thunderbolt to DVI. I can have both thunderbolts connected and the problem its the same, when back from sleep ,one monitor doesn't turn on. i have to disconnect one and then both work, it only happens when the mac goes to sleep. on cold restart or turning the mac on, this problem doesn't occur. any help.

I have this same problem too. I purchased the Mac Mini with the intention of running dual monitors. I'm using the HDMI and mini-display/Thunderbolt to DVI. I've also tried MiniDisplay/Thunderbolt to HDMI and I'm experiencing the same problem as angelfromfullerton. Whenever it tries to wake from sleep, it can't decide on monitor arrangement and keeps flicking between the two, making the OS unusable and forcing a reboot... EVERY TIME. I've also experienced the issue once or twice on a cold boot. It doesn't matter which Thunderbolt port is used either.
I'm going to have to return my Mac Mini unless this problem is fixed asap.
Mac Min, OSX Yosemite (10.10).

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).

My mac mini starts up no video

my mac mini starts up with a chime no video to the monitor any suggestions?

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.

URGENT Help: Mac mini starts up, then just "died down" (power down...)

Hello all. This is my sis's Mac mini Intel.
Was actually booting from Leopard OS X thinking of an upgrade OS, ran Disk Utility and it reported some error cannot be repaired:
Invalid sibling link
Volume check failed
Error: Filesystem verify or repair failed
So I gave up the idea, quit the installer and restart, and press "Eject" to get the disc out.
*But now, it seems like when the Mac mini starts up, with the grey Apple logo and the spinning wheel, after a while, it just "stops", "fades away" and power off. Like a "sudden shut down" or "sudden sleep"*
So far I have *tried reset PRam* and also and SMU or something (plugging every cord out etc) but to no avail.
*HELP!! At least I want to be able to do a boot up to retrieve all the data before any hard re-format or something*
Thanks and cheers

It is possible, with the errors Disk Utility reported, that some (possibly even all) of the files on the drive will be damaged or inaccessible, so it is best to proceed with some caution.
There are several possibilities for recovering the files, all dependent on the situation. You could, for example, remove the hard drive from the mini, fit it in an external drive case and connect it to another system. That would, in my view, be the best option. Alternatively, you might be able to get the mini into firewire target disk mode (hold the T key down during bootup) and connected (via firewire) to another Mac, rescue files that way, or boot the system from an external drive which has a valid MacOS install for that system, and then rescue files from the internal drive.
You may find, if the drive's data structure is corrupt, that even if you can access the hard drive via any of the methods above, you'll need a utility such as Data Rescue II (http://www.prosofteng.com/products/data_rescue.php) to locate and retrieve what you need. You might also consider use of a utility such as DiskWarrior (http://www.alsoft.com/DiskWarrior/index.html) as a means to attempt a repair of the disk so that it can be returned to use - though this is by no means certain to succeed, and may not resolve potential data loss.

My Mac Mini starts to boot up then after a few minutes turns off. Please help.

My Mac Mini starts to boot up then after a few minutes turns off. Please help.

seen this happen many times, usually always due to corrupt memory.......could be a power module in the Mini, but unlikely. hold down command R on startup, see if you can get into safe mode or ANY SCREEN ...If under warr. call mac for a service check, ....BUT if you have spare memory around that is compatable, try that first, process of elimination diagnostics.

Mac Mini HDMI Output Problem w/ LG L246WP

NOTE: This appears to be unrelated to the "screen flickering" that has been noted previously.
I'm using a fresh new Mac Mini 2012 with an LG L246WP LCD monitor. The monitor has HDMI, VGA and Component video inputs.
When I attach the monitor to the Mini DisplayPort output, using a Mini DisplayPort to DVI adapter connected to a DVI to HDMI cable, the display functions properly at all resolutions - including the native 1920 x 1200 resolution that I use it at normally. All resolutions are clearly displayed in the "Displays" System Preferences pane. The display looks perfect, functions properly.
When I attach the monitor to the HDMI port using an HDMI cable, the display does not fucntion properly. The display is shifted about 80-100 pixels to the left and about 20 pixels up, creating black bars on the bottom and right sides. Because of this, a large portion of the display is not visible including the menu bar and most of the left side. Additionally, the settings are reduced to "Best for Display" or "Scaled", with resolution options under "Scaled".
This is not acceptable. I had planned on simply using the Mini DisplayPort output as a workaround, since I already have the DVI adapter from an old setup, but I need to use Thunderbolt to access external hard drives for rapid data transfer. One of my Thunderbolt accessories does not have two ports, so I can't simply add the Mini DisplayPort adapter to a chain. The HDMI port needs to function properly with my monitor.
It's important to note that this monitor has functioned properly with many other comptuers running OS X, Windows and various Linux flavors and it hasn't ever done this before. I've tried several different HDMI cables, ruling that out as a problem. I've tried the HDMI to DVI adapter that ships with the Mac Mini 2012 along with two different DVI to HDMI adapters, ruling that out as a problem. I tried attaching several HDMI devices (game consoles, DVD players, etc) and they all function properly, ruling out an HDMI issue as a problem. The monitor functions properly when attached through the Mini DisplayPort to DVI adapter, so it's not a problem with the monitor. I've reset the PRAM already and the installation of OS X 10.8.1 is stock with no modifications or migrated data. I've tried the suggestions on the HDMI FAQ (although there's no "underscan" option available in Displays)
I tried to call AppleCare and after describing the problem I got disconnected with no callback. I started another ticket, described the problem, discussed the previous disconnection, was assured that I'd be called back if disconnected, and haven't heard back in two hours. So I started to dig into the problem in earnest.
This gets pretty technical.
After substantial research, it appears that this issue is related to the EDID that the monitor sends to the computer and, crucially, the way that the driver responds to it. For some reason, the HDMI port is recognizing the monitor as a CEA device instead of a monitor. As a result, it's restricting the monitor's available resolution to the native resolution that the CEA 681 Series Extension describes ("Best for Display") and all other resolutions (including 1920 x 1200) are only available as "scaled". For some reason that I can't discern, all resolutions (even the 1080i and 1080p options) have similar deformities.
I've attempted to fix this by placing an appropriate override file in /System/Library/Displays/Overrides with an edied EDID removing the CEA-enable flag from byte 127 but, even after a reboot, the OS still insists that it's a CEA device and it won't allow me to force it to recognize the monitor as a 1920 x 1200 LCD Monitor.
How did I come to this conclusion and develop the fix? A nearly identical problem description showed up on the following website, with details on how this user fixed the issue:
http://byuu.org/articles/computing/edid
They used a convoluted process that involved dismantling the monitor and flashing the EDID on the monitor itself. It fixed their problem. I'd prefer not to go through that process just because one computer has a problem with it. Frankly, I'd prefer if the new Mac Mini performed properly in the first place.
TL;DR: The Mac Mini 2012 doesn't work right with the LG L246WP through the HDMI output. Everything else works fine with it. This is very uncool. It's most likely to be an issue with the driver for the Intel HD Graphics 4000 GPU that are bundled with OS X 10.8.1. The Mac Mini 2012 won't update to 10.8.2 (yet), so I can't test it.
Anyone have any other ideas? Anyone else using a Mac Mini 2012 (or 2011) with an LG L246WP monitor? Anything simple I've missed?

Problem Resolved. But it was complicated. And a huge pain in the rear.
TL;DR: I flashed the EDID as described here. This is not recommended for the weary. Ideally, Apple should release an update OS X that will include the updated Intel HD Graphics 4000 drivers that utilize the CEA flag properly.
Here's the detailed version. As mentioned above, this isn't recommended for the weary. An improper (or interrupted) EDID flash can have seriously unpredictable effects on a monitor's performance.
Step 1: Get a Windows PC set up with a floppy drive and find a floppy disk. Use this system to format the floppy as a MS-DOS Boot Disk and copy over the "ddcw" program described at the aformentioned link.
This took awhile, but I was able to cobble together a temporary frankensystem with parts I had laying around. In installed XP and formatted the disk with XP's format tool.
Step 2: Grab EDID data from the monitor, modify it to disable CEA mode at bit 127 and make sure bit 128, the checksum, is appropriate.
This also took awhile. Several graphics cards I tried could not read or write EDID data. I ended up swapping AGP cards in my frankenstein box until I found one that worked - a generic GeForce4 4200.
Once the EDID data was written to the floppy, I edited the text file containing the EDID data to change the last two hex octets from "01 33" to "00 34" (00, to disable bit 127, and 34 is 33 + 1, which satisfies the checksum) and formatted the text file to match the sample included in the EDID_Write.zip file. Your mileage may vary - make sure the checks.
Step 3: Write EDID data to the monitor.
The link above mentioned three options: Easy (monitor's EDID is unprotected - write away!), Hard (monitor's EDID is protected - use service mode to attempt a fix), and Very Hard (monitor's EDID is protected, hardware modification is required).
Luckily my LG246WP simply needed to be put into service mode as described at the link above (menu + power) and once started up in service mode, I simply enabled "Aging Mode" (whatever that means) and attempted a DDCW write of the updated data.
Step 4: Profit!
After doing this, I powered off the monitor and powered it back on with the Mac Mini attached. The display functions PERFECTLY with HDMI out, just as it does using the Mini DisplayPort to DVI adapter.

Mac Mini & Analog Display Problem

We just received our Mac Mini computer. We pplan to use an existing VGA monitor (Samsung SyncMaster 730B). We plugged the monitor cable into the Apple VGA to Thunderbolt adapter. First time we powered the MiniMac we saw the Apple logo immediately at power up. The display reads "Check Signal Cable" after the computer completes its power up signal. How do we get a working display to complete the Mac Mini set up steps?

John,
A further update to our monitor problem:
After posting my last message I noted that when the display/computer goes into screen saver or sleep mode, the screen was blank with the "Check Cable" message scrolling across the screen. Unplugging the Thuderbolt connector at the computer and plugging it in again was the only way to restor the images from the computer.
This morning I replaced the original cable (and VGA connectors) with a cable that was twice the diameter of the original cable. The monitor has worked flawlessly since then at re-start from the sleep state. I conclude that either the replacement cable, connectors or both do a better job conveying the signals between the computer and monitor. It could be that there is some high speed signal the monitor looks for to initiate re-start that is distorted by the original cable.
With either cable the images and text are crisp with no distortion. I see no need to upgrade to a DVI cable and connection between this monitor and the Mac Mini now that the monitor re-start function is working.

Mac Mini Web Page Problems!

I have a mac mini that has been working great for several months. Today it started having trouble with loading web pages! It seems to have letters missing all over the page. I have tried different website and still have the same problem!
The website do come up but they are missing letters in the articles.
Any suggestions??

In my experiance, this would be due to a language error, either the some languages have uninstalled themselves (It has happened to me before) or that the language files have become corrupt... I repair and matinence macs and pcs so i have seen this before. The way to fix this would be to wither repair the language files, or reinstall. Who knows... Maybe a reinstall would be good for your system. How old is the mini?

Mac Mini Bluetooth hardware problems ?

I own a Mac Mini Intel Core 2 Duo 1Gb bought last October, an Apple wireless keyboard and an Apple wireless mouse, both I formerly use without any problems with my old Powerbook G4. By now, I used them with my Mac Mini it worked perfectly fine. But since two or three weeks, I’ve got big Bluetooth connection problem. Randomly, after one or two hours of use, both keyboard and mouse loose connection and the Bluetooth symbol change itself into a strange one. I had a look on your site to learn the meaning of it and the symbol is see which is a Bluetooth symbol with a horizontal zebra means that no Bluetooth hardware can be found! Does my Mac Mini built-in Bluetooth card have problems?
Since I haven’t got any wired USB keyboard or mouse I have to reboot my Mac Mini quite roughly. Sometimes one reboot is enough to make the Bluetooth of Mac Mini to work again, sometimes not and I have to wait a little bit more (more than ten minutes). I can see it works again as the Bluetooth symbol is the right one again (the one with the dots).
It is very annoying. And I am a bit sad to have such problems with Apple stuff. Is there something I could do to avoid such a waste of time? Or shall I call Apple Care for fear it should be a hardware problem.
Of course, I use brand new batteries for both of them.

My mini is doing it as well. Just started doing 2-3 weeks ago. Logitech Denovo or Apple Bluetooth. Doesn't matter which. Loses it in about an hour or so. Al Keyboards and mice were purchased at about the same time as the core 2 duo mini, ~ last October.
Must power cycle the machine to get it back and it must be paired again. Very annoying. Can't remember if it coincides with an Apple update.
This mini has had the superdrive replaced twice, once within 6 weeks of purchase. Ever since Leopard, it's been close to the best media head. now this...
Sigh.
(What makes it not the best? Frontrow doesn't sort titles correctly [1, 10, 2, 3 - wrong!], doesn't force mount aliases in the movies directory, doesn't put out 1080p without hacking. And I'd so love eyeTV integration with Frontrow. It'd be perfect then.)
