HT2714 Mac Mini won't launch after it has been reprogrammed using Command+Option+R?

Out of nowhere while using my Mac MIni it goes whacky and I get a white/grey screen!! I diagnosed the hardware...read out "No Problems". I try restarting the computer. No luck...same old story! I tried to reprogram it holding down the Command button+Option+R....the unit starts to reprogram and finishes after about 34 minutes. Still same old story, white/grey screen! I will be making an appointment to get it fixed. It still under warrantee. In fact it only 44 days old!! Any ideas on how to restore it now, instead of me having to travel an hour to drop it off to get it fixed???

Using CMD+r try erasing & reinstalling the OS.

Apps won't launch after Terminal has been launched.

I just started noticing this recently. Before I launch terminal, I can open and close as many apps as I want. After I launch terminal, no apps will launch. They just keep bouncing in the dock indefinitely. Does anybody else have the same problem?

I deleted the file, but it did not work. Terminal was still interfering with launching my other apps. If I do a fresh Snow Leopard install, it would work fine, but after I do a Time Machine restore, or Migration Assistant and transfer my user account over, the problem came back. I ended up reformatting the HD, do a fresh Snow Leopard install, and used migration assistant to copy over ONLY my home folder, nothing else. I ignored the copying over the Applications, Settings, and Other. Now my system is working fine, but I have to reinstall a bunch of Applications now.

Mac Mini won't start after installing OS X 10.6.3

My Mac Mini won't start after installing Mac OS X Snow Leopard 10.6.3. When I turn it on, the Apple logo appears and the initialization line starts to fill, but it suddenly stops. It does that again and stops at the same point, but this time it shuts down. What should I do?

If you are coming from 10.5.8, hopefully you backed up your important data first. Your mini will need at minimum, 1 GB of RAM to install Snow Leopard and at least 5 GB of storage remaining on your boot drive.
I treat 10.6.3 as a fresh, full install over a 10.5.8 system. That means I choose Disk Utility from the Installer's menu and repartition the boot drive as a single partition, Mac OS X Extended (Journaled) format, and use the GUID partition scheme from the options button. At this point, while still in Disk Utility, I would verify the drive under First Aid.
Then I turn the installer loose, and reboot into a working 10.6.3 system, ready for the software updates that take the machine to 10.6.8.
So, following the above guidelines, reinstall 10.6.3.

How many Mac Mini's sold? and what has been the most popular Mac?

How many Mac Mini's sold? and what has been the most popular Mac? Curious, Bill

If you visit Apple's PR Library, you can find the quarterly sales results posted. Each one has a PDF you can download that includes a summary of Macs sold. The most recent one, from April 19, 2006, includes a PDF ("Data Summary" at the top of the press release) that only breaks down the Macs sold into "desktop" and "portable" computers. There's no way to distinguish between iMacs, G5 towers, Xserves and Mac minis in the desktop category. Older press releases like that (for example, the April, 2005 release) break down the desktops into iMacs and PowerMacs, but the iMac group includes the Mac minis and eMacs so it's still not possible to figure out exactly how many Mac minis were sold.
So, unless Apple releases the numbers separately, I'm not sure it's possible to answer your question.

Mac mini won't boot after RAM upgrade.

Tried installing new RAM in my Mac Mini, 512MB stock to 2GB of Crucial. Followed the directions to a T, grounded myself the whole time.
Things I've tried so far:
1. Resetting the PRAM, no luck.
2. Holding option at start-up, shows no icon.
3. Holding shift, no luck.
4. Holding X, nothing.
How do I get it to accept a CD if it won't boot?

Welcome to Apple Discussions!
You clearly have a problem, but you don't describe exactly what that is other than that your mini won't boot after the upgrade. What happens when it starts up? Does it attempt to start and hang up on the grey or blue screens, or does it start beeping at you almost immediately after you try and start it up, and also flash the power light?
If the former, then you may have dislodged a connector while working inside the system, in which case opening it up and checking that everything is firmly connected would be the first thing to do. If the latter, then the beeping/light flashing is the system telling you it has failed the power-on self test and the pattern of beeps/lights indicates why. In your case likely the system can't find workable memory. In that instance, opening the system and ensuring that the RAM is firmly and fully seated would be a good step, and if the mini continues to fail, then replacing the new RAM with the original to test that the system will then start.
It is not likely that anything had damaged your MacOS install in the process of upgrading, thus normally no reason to need to boot to CD as a result of a RAM issue.

Mac Mini Won't Sleep after installing 10.4.6

My Mac Mini wakes itself up after just 1 minute of putting it to sleep mode. I've tried restarting my mini, and tried quitting all apps and disabling airport and bluetooth- but it still won't sleep! Anyone else experiencing this problem, I didn't have this problem with 10.4.5 and I've installed no other software since then...

This is for a Mac that won't sleep.
First, read things in Apple doc.#25801 on sleep settings.
USB devices and hubs often cause Macs to not sleep or wake quickly from sleep (notably HP printers and scanners, HP all in ones, and Cannon scanners). Disconnect all USB except for keyboard and mouse and try. If it sleeps, add one back at a time testing after each one to find the culprit.
If you've set your Mac to recieve faxes, it may not be able to sleep. It might also have a damaged preferences file.
If you use your Mac for faxing, open System Preferences. click Print & Fax, click the Faxing tab, and uncheck the Recieve Faxes On This Computer box.
If that does'nt work or you've never faxed on your Mac, go to Finder/Hard Drive /Library/Preferences/SystemConfiguration and delete the com.apple.PowerManagement.plist and com..apple.AutoWake.plist files (if your Mac asks, type your admin. password).
If the latter file isn't present in the folder, go to user name(probably your name)/Library/Preferences, delete the com.apple.systemuiserver.plist file, and reboot your Mac.
Hope this helps!
P.S. One member here reported this (Michael Gleason);
"I have had this problem with my IMac G5. It is surprisingly irritating. LaCie's Silverkeeper backup software was the cause. By default it gave itself permission to wake up the computer to check if a backup was needed. Do you have this or a similar program installed which has scheduled activities including wake-up permissions as an option?"
Dave Hamilton provided this link, xlr8yourmac.com, to a member, which addresses failure of deep sleep with some users that updated and added new FireWire and USB cards.
tomhorvat adds this; After few days of messing around I found out that I had desktop background (wallpaper) set to change every 1 minute.
After unchecking "Change picture..." in system preferences (under Desktop/Screen saver), my powerbook went to sleep all by itself.
Cheers!

Mac Mini won't boot after failed XP installation

Recently upgrade HD to 320GB 7200 rpm and 3GB ram. Running 10.5.8 fine.
I tried to install Windows XP through Boot Camp, but wasn't successful, I terminated the installation. Then Mac Mini won't boot up. When powered on, you heard the chime, then grey screen showed and stayed. Tried starting with "C" (boot from CD), "OPT" (boot option), "T" (target), and reset PRAM. None of them worked.
What should I try next?
Thanks

If you install XP on Bootcamp, your startup disc will be changed to XP Windows partitioned you did. To restore your startup disc back to Mac OS, make sure your Mac is turned off. 1. Plug the power back and press the power button ON. When you hear the power On sound, press and hold the ALT key on your keyboard until you see the hardrives. 2. Select the HD that says MAc OS, then your mac will boot back to Mac OS.
Let me know if you have more problems, maybe I can help.

Mac Mini won't boot after PRAM reset

My mac mini has been running very slow, VERY VERY SLOW, then it would seem it would catch up with itself and run fine for a few minutes, then slow down again. It got to the point where I would have to do hard resets, but it still wouldn't work all that great. So I read on here to do a PRAM reset, which I did by holding down controloption+PR, and i got a gray screen with a status bar. But now the mac won't even boot up, even when I try safe mode. I turn it on, and i hear the start up tone, and get to the gray screen with status bar, but then it just shuts off. Does anyone have any suggestions?

From your user guide:
1 Disconnect all external devices from your Mac mini, except the keyboard and mouse.
If you have an Ethernet cable connected, disconnect it.
2 Restart your Mac mini while holding down the D key.
3 When the Apple Hardware Test chooser screen appears, select the language you want
to use.
4 Press the Return key or click the right arrow button.
5 When the Apple Hardware Test main screen appears (after about 45 seconds), follow
the onscreen instructions.
6 If Apple Hardware Test detects a problem, it displays an error code. Make a note of the
error code before pursuing support options. If Apple Hardware Test doesn’t detect a
hardware failure, the problem may be software-related.
If this procedure doesn’t work, you can insert the Applications Install DVD that came
with your Mac mini to use Apple Hardware Test. For more information, see the Apple
Hardware Test Read Me file on the Applications Install DVD.
When prompted, choose the extended test.

Mac mini won't boot after latest update Maverick

My Mac mini running Maverick after an automatic update won't boot. " no bootable device -- insert boot disk and press any key"
What option do I have here?

Reinstall Mountain Lion or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is
three times faster than wireless.

Mac Mini won't boot after update

I have a Mac Mini that won't boot after the most recent software update. Since the Mini has only a bluetooth keyboard and mouse, a number of the usual options (hold down shift, etc.) won't work. I've tried a reset, also no luck. At the moment, I can't locate my Tiger install CD either.
When holding the power button on during boot, I get a series of flashes from the status light on the front (a set of very rapid flashes, followed by a slower set, followed by a slow set) but no startup chime, or fan, or video. My display and power source are both known-good (work fine with my Powerbook)
Any suggestions, other than buying a hardwired keyboard/mouse?

Welcome to Apple Discussions!
The 'newer version of OS X" error occurs because the installer on the DVD you have booted to has by default been set to update the version of MacOS on the hard drive, which of course it can't do because the version of MacOS it is installing is newer. The only way to install in this situation is to select a different option. However, that isn't what you want to do at this point, because as it says, you'll loose your data if you do an 'erase and install'.
Instead, you should see menus at the top of the screen when it's booted to that install disk. Click the Utilities menu, select Disk Utility, and then click the top entry for the internal hard drive on the left. Once done, click on the 'Repair Disk' button (not Repair Permissions). This will test the drive to make sure it's OK. If it reports errors, and then reports 'error or exit' with the drive not repaired, you will either need a 3rd party application such as Alsoft's Disk Warrior, or to perform an erase and install (which of course you don't want to do at this point because your data is not backed up).
If the Repair Disk process completes with no errors, next select Repair Permissions, and let that process complete, then reboot the system as normal to see if you can now access the drive.

Mac Mini Won't Boot after 2008 008 Security Update

I have 2 mac mini's both identical systems - ran the security update at home - rebooted and noticed the movements of the mouse and the mail application was 1/2 to a second slow/behind - decided to restart - it took 3 restarts and it finally came back and then locked up
I ran Disk Warrior and version 4.0.1 could not fix the problem - version 3.0.3 said it could and replaced the directory - but upon restart it would not boot - I became mesmerized by the spinning dial
I will not run the update at work and had to substitute my titanium at home in the meantime
ugly...

Mac Mini won't Boot after Target Disk Mode

We just bought a new iMac and used target disk mode via firewire from our older Mac Mini running OSX 10.4 to transfer data. Now when we go to restart the mini, the grey screen appears with apple logo and it seems to try to boot up but after a long time alway just ends up with a blue screen. I don't think I "ejected" the mini properly from the imac after the target disk mode transfer. Could the mini be stuck in target disk mode? I've tried to restart in different modes eg. safe mode, pram by holding down keys on start up but doesnt make a difference at all almost as if the keyboard isn't registering (and its a wired keyboard). Any ideas???
Thanks

Try starting up from the Recovery Partition holding the Option (Alt) key and see if you can Repair your Macintosh HD, as per > OS X: About OS X Recovery

Mac Mini Won't Start after RAM upgrade

Hi, I just tried upgrading my RAM from 1GB to 2GB on my Intel Core Solo Mac Mini. When i hooked everything back up it wouldn't start up. So I replaced the original RAM and the same thing happened. I get to the gray apple screen with the gray spinning wheel and then it just shuts off. What could be my problem? Are their any solutions?

Welcome to Apple Discussions, though I suspect the circumstances could be better!
It's not unusual for 'bad RAM' to cause a system to fail to boot, but the disturbing feature of your problem is that when the previous memory is reinserted, the system continues to fail. What makes it worse is that you describe the system shutting off after failing to boot - that is not a common symptom of something simple like bad memory, and may mean that in the initial upgrade, something was damaged or dislodged, or not reconnected correctly.
I would open up the system again, and disassemble it sufficiently that you can reseat the original RAM which was working correctly prior to the upgrade, then check that everything is connected correctly internally, and the CPU heatsink is firmly attached. If that doesn't result in the system working, or at least in different symptoms such as being stuck on the grey screen but no longer shutting down, then I would look for an Apple store in the area and make an appointment at the genius bar for them to have a look - that would not bear a cost in the first instance for them to give their opinion.

Any ideas how to solve?

You can go into the OS X Server Forum and search for this issue. I think there are some discussiom threads that discuss it and you can read some of the solutions.
I'm also running Mountain Lion 10.8.2 and OS X Server on a Mac Mini and it won't sleep if I have the File Sharing, VPN and Printer Sharing services running. To me, this is a good thing as a server is usually available to client machines 24x7.
I did experiment and turned off each service one at a time to see which ones deny the sleep function and I found all 3 do.
Here's an example from my server. The bold entries are the culprits for my server.

Mac Mini won't boot after wind storm flickered lights

My Mac Mini running OS X 10.5 will start up but won't go beyond the Apple logo.
I can't even get it to start in Safe Mode. Is there any way around this problem besides
buying a new computer?

Usually, if there is a power disruption (or a static shock to the computer) and it does
not work correctly, you may be able to perform a power management unit re-set;
if the computer is a G4 PPC Mac Mini, that would be a PMU reset. If the computer
happens to be a later Intel-based Mac Mini, the procedure would be an SMC reset
and different rules would apply. I have added links to both methods in this post.
There is a chance some hardware damages may have occurred to the computer due
to being unprotected and not isolated from grid power fluctuations; such as provided
by use of an 'uninterruptible power supply' or 'backup power supply' which would be
able to switch to battery backup automatically when the main power goes haywire.
Which model Mini do you have? Since I have a G4 PowerPC Mini, I know something
about resetting Power Management Unit procedures since I've notice the Mini is more
likely to need a reset due to static shock when normally touching the computer; with
winter weather and less indoor humidity. (Otherwise, I have UPS power protection.)
Links to both kinds of power/system management reset procedure are below.
• PPC-based G4 Mac Mini: How to reset the PMU
http://support.apple.com/kb/HT2183
• *Intel-based Macs:* Resetting the System Management Controller (SMC)
http://support.apple.com/kb/HT3964 (mini reset instructions, as follows)
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.
{You may wish to read through the entire Intel-based Mac article if your Mini
is of this architecture, since there may be applicable hints for all Intel-Macs.}
Not sure about your other continuing issues; I'd have to re-read the posts,
since I have been interrupted three times during this post, locally...
If the computer does run, eventually, it may be some directory damages or
other sector or data errors have occurred in the computer's hard disk drive;
and you may have to consider buying Disk Warrior on disc so you can boot
the computer from its disc to repair the Directory on the hard disk drive.
Restoring is easier if you should have a complete clone of the computer on
an external hard disk drive; one that is capable of booting the computer.
Good luck & happy computing!
