Mac Mini :: Won't Boot After Accidental Loss Of Power During Firmware Upgrade
Feb 19, 2012
i accidentally hit the power switch on the wall during an upgrade (might even have been a firmware upgrade, I didn't really look at what was going on). Anyway, now it hangs on the silver Apple logo screen with a spinny wheel on reboot. It's only 3 months old, it's the $599 model.Â
What to do? I see that you can download firmware restoration disks but they appear to be limited to earlier versions of the Mac mini.
Info:
Mac mini, Mac OS X (10.7), I think the OS is OSX 10.7...
I recently applied an EFI firmware update to my MacBook Pro 15" (early 2011), which is currently running OSX 10.7.3. Coincidentally, my clock now loses several seconds per hour (in both sleep or screensaver mode), so after several hours, I lose about a minute. Of course, I could manually correct the clock via System Preferences' Date/Time synchronization. But I shouldn't be losing this much time.Â

I just recently bought 8gs of Corsair Mac RAM, links at the bottom.So they I changed the RAM sticks, not the first time I've upgraded RAM, just like I have every other time.But after switching the RAM the mac won't boot. Tried swapping back the old ones and still nothing.
I was upgrading rame in my 2011 mac mini and removed the first module without incident but upon removing the second module the clip on the left broke and upon trying to reseat the 2 new ram modules so I could at least boot my mac the lower one is loose (which I expected but upon inserting the top one the clips did not grip it and not they are both stuck loosely in the mac mini which will not boot.Â
After having installed rame in a PC laptop and my mac ro I have had 2 successful ram upgrades so was not impressed to find that the ram upgrade process in the mini has some really bad clips.Â
So now what do I do and to complicate things even further there is some stuff on the mini I need.
I run MBP without battery 99% of the time to safe its 300 or so cycles and I occasionally trip the mac safe adapter (which i find gimmicky and annoying) by maneuvering MBP around when sitting down & the cable gets snagged momentarily on corner of coffee table etc and out goes the power !!
Is this causing any damage ?!? I havent noticed any ill effects.
I also understand from reading other threads how the processor speed reduces without battery but thats ok considering most of my use is limited to web browsing..
I have Mac Mini 1.5 solo that work very well for me and my son untill we updated the EFI 1.1 a week ago and never booted back up. I call apple and was told bad hardware maybe caused by update they send me to a Apple store to get it checked but there they said it was the power button not the flash. I had it plug in to the wall the hole time at home but when i took it there it booted as soon as he plug it in so he shut down and it did not boot, he unplug it for a few seconds plug it back no good with button but did boot a few second by itself. I replaced the button my self for a few hunder less then what Apple Was asking for (160.00 less). Still not luck. I feel i got screwed by Apple on this. Has anyone seen this and how it fix.
I am using an external hard drive with Airport Extreme for Time Machine. Should I be worried about my data in an event of power loss because the drive is always mounted? Has anyone loss a drive due to power loss and what have you done to fix it or prevent it? What are you using as backup power and why? I know I can go with Drobo, but are there other lower cost options?
For the past two weeks or so I have been getting a lot of Kernel Panics. Most of them happen when I select Restart or Shutdown. There have also been cases of Final Cut Pro crashing regularly, but I think the Kernel Panics are far more important to diagnose. I have not changes any hardware for at least a year. The machine has 4.5gb of RAM and 40% of the system drive free. I have run Disk Utility to repir the disk as well as the permissions, all coming back with no errors. The only thing that I can think of that changed is that I purchased and ran Disk Warrior 4. It seemed to help tremendously with performance, however, it is the only thing that I can think of that has changed. I am also suffering from some performance loss as well. I get at least one Kernel Panic a day. I have no idea what the KP mean, but they all look similar.

I have here a mac mini 4,1 that keeps losing it's Ethernet connection. If the mac is shutdown and restarted there is no connection, however, if the mac is shutdown, all the cables pulled from the back and replaced then restarted it boots and the connection is back. It was reporting a very strange mac address starting with 00 which I've never seen before and I also had difficulty connecting to it via ARD as it would show in the scanner but not connect unless specifically connected via IP address. At first I thought it might be a system upgrade as it happen when we upgraded to 10.6.8 since then I've wiped it and installed 10.6.3 and still no luck.Â
Hook up a $3K machine to a $1.5K display and have to hard power down your $3K machine to get the picture back.When I boot everything is fine. If I change input to TV or power off the display, when I power back up or switch back to hdmi input screen displays error, can't read signal check output device. I have read on this forum about a issue similar with ATV but not with MacPro. In my google searches I read some issues with Vista, but no resolution... thought to be a ATI driver problem. Does anyone know of a tweak to fix the ATI 2600 XT to remember the tv signal after you change inputs or power off the display?
I have a problem described by Apple in document Power Mac G5 (Late 2004) 1.8GHz models stop responding randomly.
How can I update the firmware because my G5 1.8 screen is blank? Thought that I could make my G5 1.8 as a hard disk for my MacBook, or I may try to update over the network. Is there a risk of corrupting my MacBook if I try?
i have mac mini, but this is one partition. I want to create partition of disc, but i doughtful that when i create partition, data and software will delete. Can i create partition without data loss.
I recently tried to install OS X Yosemite. unfortunately during the install my laptop was unplugged and the installation failed mid way through. Each time I start my mac I get to login screen and after logging in get an error message and told to restart and try again - which does not resolve the issue. Guest login do work to the safari screen.
The error message reads: You need to restart your computer. Hold down the power button until it turns off, then Press the power button again.  Behind system code, including:Â

I have a March 2009 Mac Mini that was working fine under Leopard when sending out a signal from mini display port to hdmi and then to a Samsung HDTV. Now when I upgraded I get more options for monitoring HD signals but my TV signal drops out intermittently. I suspect this is a bug with Snow Leopard and HDMI. Anyone have any inklings on how to solve this issue?
In short, we got a new Mac Mini on Friday. I hooked it up to the wireless keyboard/mouse from the Dell dimension 2400 we are replacing. It seemed okay at first but developed issues the first day. Intermittent mouse drop outs, and loss of internet being the worst symptoms. I am thinking of ditching the Mini and getting something else.
Need to remove a firmware password on a G5 2.7 Powermac bought on ebay.Have removed half of the ram and tried to reset pram no help. Removed battery, no help.Former owner forgot password, never logged out.
how can i update the firmware/bootrom to 4.2.8 for my power mac g4 ( gigabit ethernet) ? i am using mac os x 10.4.11, and dont have a disk with mac os 9.
My machine is locking under specific conditions:Hardware Overview:  Model Name:MacBook Pro Model Identifier:MacBookPro8,2 Processor Name:Intel Core i7 Processor Speed:2.4 GHz Number of Processors:1 Total Number of Cores:4 L2 Cache (per Core):256 KB L3 Cache:6 MB Memory:8 GB Boot ROM Version:MBP81.0047.B27 SMC Version (system):1.69f3 System Version:Mac OS X 10.7.3 (11D50b) Kernel Version:Darwin 11.3.0 Boot Volume:Macintosh HD After I have updated the EFI firmware to version 2.7 last week, I noticed that my memory utilization has gotten higher. Has anyone experience that? Before the upgrade, even when I opened my Fusion VMware, I will still have at least 1-2GB available left but now I only left with 200MB available. How do I troubleshoot? Regret that I upgraded the firmware.
After using Open Firmware Update my G4 went into a crazy circle. At first, it was impossible to start up, and when it was possible, just for a couple of seconds, and then the translucent screen asking you to restart the computer pressing for a few seconds the start up button.

I have a iMac G3. I can't make it boot from the CD to install the OS. Keep pressing the C key, but no luck. How can I edit it in open firmware to make it boot from the CD? Or, is there another option to install the OS from a different Mac? I have Mac OS X installed on a PC.
So, I'm still having trouble with the MacBook I posted about here. It kernel panics even more frequently now, a month later, about once every 30 minutes. I'm running 10.5.8 now (no Snow Leopard for me!).
Anyway, the problem I'm posting about is that I can't boot into Open Firmware. It works fine just booting straight through to OS X (except about a third of the time I start up it kernel panics right after the Apple logo appears) but it won't boot into Open Firmware. I hold down Command-Option-O-F to no avail and it just won't go. (I'm trying to do reset-all to see if that helps any.)
I tried booting into Open Firmware successfully on my other Mac so it's nothing I'm doing, this MacBook obviously has some serious issues.
I'd rather not have to take this computer to the Apple Store again - every time I do they just reinstall the system/replace the hard drive and don't take me seriously when I say the problem is not with software. (Plus the warranty on this machine is up now and I'm trying to avoid paying hundreds of dollars!)
Anyone know what the issue could be? i really need a new computer hahaha...
Oh! I also tried booting into Open Firmware by holding down the power button continuously as suggested here... the on/off light blinked 3-4 times, the computer made a really long beep (like I was trying to do a firmware update), then started as normally. So I don't think that worked either lol.
I have a dual 1.8 PPC G5 power mac that I bought used about a year ago. It came with OS 10.5 preloaded but the only discs I have for it are the original system disks(10.3). I've got it hooked up to a HP 19 LCD via DVI. The other day I tried to boot into open firmware using the command-option-O-F start up command. Well, something happened cause OS X never came up, but nothing else did either. The screen just stayed blank, the fans starting ramping up and just got gradually louder and louder. I tried entering mac-boot via the keyboard thinking that maybe I was in OF even though I couldn't see anything on screen, but nothing changed.
having issues updating thier firmware? Software update shows the 1.6 firmware update needing done, I go throught the process, it reboots and never installs the firmware. System profiler still showing the old version. I tried downloading the file from Apple's website and manually installing and it does the same thing. I'm at my wits end here. It doesn't really bother me except that it constantly shows up in software update.
I purchased a G5 in 2005. Never once used the drive for DVD. So I decided to use it today, and it doesn't work. I tried to burn a DVD that didn't work. The drive doesn't even recognize it. I did some research, I came to the conclusion that I have to update the pioneer d112 firmware. Seems simple but the pioneer update is for windows format!
My MacBook Pro (Late 2011) which is fully up to date, no longer boots up. The last thing I did was set a firmware password via Lion Recovery mode. After setting the password, I restarted the MacBook Pro, logged in, unbound the Mac from AD and OD, gave it a different computer name and chanegd the IP settings to DHCP. I shutdown the MacBook, plugged in a Firewire cable and turned it back on whilst holding down "T" to boot into Target Disk Mode.
The screen turned on for a second then suddenly turned off and the light on the front of the MacBook slowly pulses as if its in sleep mode. I've restarted the MacBook several times, with and without holding down any buttons and now it will not boot up properly. When you turn the MacBook on, you can hear the CDROM Drive/HDD moving - like it usually does but with no feedback on the screen. After the normal sounds have stopped the light on the front of the MacBook pulses as if its in sleep mode.
"Boot Camp Assistant cannot be used: You must update your computer's boot ROM firmware before using this setup assistant"."
That's the dreaded message I get every time I try to use boot camp 1.2. Unfortunately my firmware is already updated, and any attempt at updating my firmware (again) results in the message that I "don't have to update my firmware."
I've google'd this problem numerous times, but I have yet to find a solution.
I have a late 2008 alumunium Macbook 2.4GHz, upgraded to 4GB RAM, running Snow Leopard 10.6.2. Due to a kernel panic earlier today I went through the websites shown in this thread: [URL]. As I was doing some of the procedures, I came across a website about EFI and SMC firmware updates for Intel-based Macs shown below: [URL].
According to that website the Boot ROM Version on my late 2008 Aluminium Macbook, should be MB52.008E.B05. Instead it is MB51.007D.B03
If I understand correctly, the support website probably has a typo, because my Macbook is coded Macbook 5,1 and not 5,2. Also on this website: [URL] it says MacBook5,1 will update to MB51.007D.003, which is still not the number I have in the System Profiler. Of course the above website has Mac OS X 10.5.7 as a requirement, so I'm not sure if the number changes in Snow Leopard. I just want to know if the Boot ROM Version in my System Profiler is ok, or if something is wrong.
i just restored new Mac OS 9 already so now i have a problem that say i need to update firmware so i follow the instruction i hold the programmmer button and it just pop up with white screen say welcome to firmware update continue mac boot or shut down? i have no clue why is that i mean it say it will update loud buzz so i waited for long and it didn't
