Arch only booting in IDE mode

Hi, I installed archlinux on my desktop a few months ago. I did not realize that the SATA bios settings were on IDE mode when I originally set up my system. I want to make it so that I can use hot-swapping, and for this I absolutely need AHCI (not IDE). In any case, IDE is not the most appropriate for the types of drives I'm using (SATA 3 drives, one is an SSD).
Anyway, HERE ARE THE ERRORS THAT I SEE WHEN I TRY TO BOOT IN AHCI MODE:
ERROR: device 'UUID=***' not found. Skipping fsck.
ERROR: Unable to find root device 'UUID=***'.
You are being dropped to a recovery shell
Type 'exit' to try and continue booting
sh: can't access tty; job control turned off
[rootfs#]..a shell prompt here
I have read that the best thing to do is use the mkinitcpio command from an installation disk, is this right? and if so, why wouldn't I get the same error in IDE mode???
Furthermore, when I'm booting in IDE mode I see this error:
ata4: SRST failed. errno = 16
ata4: SRST failed. errno = 16
ata4: SRST failed. errno = 16
ata4: SRST failed. errno = 16
then it boots...each with about 30 seconds of waiting between each
I have tried making a blank file called /forcefsck in my root directory...that didn't work.
I am running kernel no: 3.9.4-1, also I am using reiserfs
really not sure what to do to make this work?? any ideas would be really helpful.

You should be able to boot using the fallback initrd, since it presumably has ahci support built in. That's easier than fooling around with an installation disk.
The reason you don't get this error in IDE mode is that when you installed, it ran mkinitcpio and generated the initrd based on the modules that were loaded at the time, which would have included the ide/pata driver, but not the ahci driver, since you weren't using ahci mode. Without the driver, it can't read your disks, hence why it can't find your root fs.

Help! MacBook Pro only boots in Safe Mode and runs extremely slow (bonus: happened in Brazil and there are no Apple stores here - I need you guys!)

It's a MBP mid 2010. Last year it had some problems and an Apple authorised shop changed the HD and upgraded the OS from Snow Leopard to Lion. After that it seemed fine. Recently it started getting very slow and apps (e.g. Chrome, Flash) would crash. At some point it seemed stuck so I gave it a hard shutdown - bad idea. After that it would only boot in Safe Mode. I ran repar disk and repair permissions from the Disk Utility and it booted normally again but extremely slow. I upgraded to OS X 10.8.2, but didn't solve it. I tried booting with Command D to have a hardware diagnostic - it wouldn't boot and now it only boots in Safe Mode.
All data is backed and I have an external HD (but not an OS X Disc). Ready to anything. Help please!

Also you can perform #1 and #2 as these occur before Safe Mode, so you just reboot again with Shift key if you need to enter Safe Mode again.
At this point it sounds like your hard drive is dying or some sort of other hardware issue which I can only advise this.
Try to install OS X on a external drive and boot from it, if it's fine then you know your internal boot drive is dying.
Create a data recovery/undelete external boot drive
You can replace your internal drive yourself.
OtherWorld Computing is pretty good about providing drives and tool kits to perform that function yourself.

MacBook Pro 13" Only boots to safe mode and running VERY slow.

Hi...
Not posted on here before, but am desperate so hoping there are some experts out there who can help...
I have 13" Macbook pro which has ceased to work properly - it runs very slowly and will only boot in safe mode.
I have installed a new hard disk, but I get the same problem whether I (try to) boot from the old HHD or the new one.
The new drive was imaged using Carbon Copy Cloner.
I have run the repair disk priorities in disk utility and verifying the disk says all OK.
I have set the startup disk to be the new hard disk, and cleared the NVRAM via cmd-option-p-r...
As things stand at the moment, rebooting (not in safe mode) leaves me with the grey screen and apple logo (and no obvious activity for 10+ mins (so far)).
Booting in safe mode takes 3+ mins but I do get to a user login prompt and can get to a desktop.
Any ideas / help very much appreciated as I urgently need to get this machine working!
Thanks!

Domonic White,
when you ran Disk Utility, did you do so from your user account, or from Recovery mode? There are four options there: Verify Disk Permissions, Repair Disk Permissions, Verify Disk, and Repair Disk. Which of these did you do in Disk Utility?
Have you tried resetting your MacBook Pro’s System Management Controller?
Have you tried logging in as your administrative user, opening the Users & Groups pane of System Preferences, creating a new standard user (e.g. “Test”), and trying to log in as the new user, to see if the slow performance affects the new user also?
There is a chance that this could be due to a faulty internal SATA cable. If you have an external disk enclosure, or a SATA-to-USB or SATA-to-FireWire adapter, try booting from one of your drives when it’s externally connected. If it works fine that way, but is sluggish when internal, that could point to your internal SATA cable as the culprit.

My macbook pro will only boot in safe mode

Hey,
I have a macbook pro 15-inch, Early 2011 running osx 10.9.4. I have a SSD hard drive that i installed myself a year ago and hasn't shown any defects. Its a 120 gb OCZ-AGILITY3.
My problem:
My macbook will only boot in safe mode nowadays. I have done a complete erasion of my hard drive and installed osx mavericks twice already. After the installation the computer will safely go to the desktop. But if i then do a reboot it won't get further than after the first apple logo, sometime the turning wheel will pop up, before turning off and trying again. i have tried resetting PRAM, I have tried resetting SMC, i have tried avoiding SMC (with big fan rate), but all with no success.
I have done a complete hardware test (the longer one) and it showed "no troubles found".
My guess is that the problem is with the battery. My computer won't run anymore without the adapter, when i pull the adapter out it either stays on for a while before just turning off. Without having it plugged in it won't start. Is it possible that during normal start up there is some kind of communication with the battery that can cause this?
I ran a diagnostic shown in this thread (Will only boot in safe mode) and included it in this post.
Hope someone can help me out.
Thanks,
Bram

How can I transfer files from a 27" iMac which will only boot in safe mode?

My late 2009 27" imac is having issues and will only boot in safe mode. I have tried to transfer files to a new Imac using migration assistant but it wont let me. If I try booting the old Imac normally I just get a grey screen, I believe it is the video card failed and am waiting for a fix, but I would like to transfer files before the fix in case something goes wrong and I lose everything.
Any help would be great

Hello Myles, likely it is a Hardware problem.
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...

Macbook Pro only boots in Safe Mode

Hello,
I've read a few discussions about MacBooks only booting in Safe Mode, but my circumstances are a bit different.
Yesterday I installed a new piece of RAM. The installation was careful and went well. When I went to restart the computer, however, it would not load after the gray screen with the apple appeared. So I restarted it in Safe Mode and it worked fine (abeit there is no sound, can't use the disc drive, etc.)
The interesting part is that while in safe mode I clicked on the apple in the top left corner, clicked "About This Mac," and it appears that the computer accepted the new ram (I originally had two 2-gig sticks [4 gigs total], and I swapped out one of the sticks for the new 4-gig stick [therefore I have 6 gigs total]). So the computer recognizes the new RAM, which is good news, but I've still got a problem.
I've tried rebooting several times, and have even tried the Apple Hardware Test, but it froze shortly after I started the test (the same thing happened about 4 times).
Any help would be greatly appreciated!
Here's the specs of my Macbook:
MacBook Pro, mid-2010 edition
Mac OS X, version 10.6.8
2.4 GHz Intel Core i5 Processor
6 GB 1067 MHz DDR3 Memory

The RAM you received was bad, return it. That brand of RAM seems to pop up a lot here as a problem for Mac's.
According to MacTracker the Mid 2010 models with i5 processors can accept 8GB of RAM.
Maximum Memory
8.0 GB
Memory Slots
2 - 204-pin PC3-8500 (1066 MHz) DDR3 SO-DIMM
Amazon and eBay are not good sources of top tier reliable and tested RAM, your just going to be spending more money returning it.
Crucial.com or OtherWorld Computing will make sure the RAM they sell you works correctly in your model/year of machine.

Lion 10.7 Only Boots in Safe Mode. Is This a Hardware or Software Issue?

Hi. On my iMac late 2009 i7 8GB bought last March only. I reinstalled Lion (I didn't erase the whole disk because I have Boot Camp Windows and I have filed there) and it can only boot in safe mode if I use the Mac's built-in EFI bootloader (where you have to press option on restart) menu then press shift after choosing the iMac OS X hardisk. I've been trying to fix it for around 4 days now today. I'm tempted to take it to the authorized Mac shop but that could take weeks to months in our country. If I let it boot normally, it would seem to have a kernel panic and would stop at the white/gray screen. Verbose mode showed that is stopped at something 10 of these like: nstat fail.
Is this a GPU hardware problem, specifically the 3D element of this 4850M GPU? I'd like to do load each kext, each extension manually but I can't find them in Lion. When I use the Lion DVD or the Lion Recovery partition, it's very sluggish, every click and process takes 20 seconds to minutes. If I try to boot in Linux, Snow Leopard DVD or Snow Leopard external hardisk, there seems to be a kernel panic. It's either just a black screen or a garbled screen.
I want to erase/format the iMac's hardisk but in Safe Mode, it can't be mounted even if I use Disk Utility. If only there's a way to force it to mount, I can save some Windows 7 file to one of my external hardisk or flash drive. Does anyone know of an app or program that can mount NTFS files on Lion's Safe mode?
If it's a Lion bug, has Lion somehow corrupted the Mac's built-in (hardware not the EFI partition in the hardisk) EFI or somehow corrupted the Mac or GPU's ROM? Could it be a new OS X virus? Should I then perform in Safe Mode to flash the GPU ROM and the Mac's ROM again (I have the latest)?
Do you think if I erased the whole drive, reinstalled it again with either Snow Leopard (assuming it doesn't boot into a garbled screen) or Lion things will go back to normal?
Has anyone experienced something like this? What was the culprit (was it a hardware or software issue) and what was the solution?
Gbu.

Hi thanks for all the concern and replies. I've tried all that.
I had just got it back from the shop last Friday. It was there for around two weeks. It was a faulty GPU (when you see garbled display that's consisten when booting it the GPU). I have a strong feeling it's related to the Lion install 10.7 or 10.7.1 and may be similar to reports of Mac laptops overheating. It's good the GPU is removable, it might have taken 3 week or a month if it had been the whole board.
It's a blessing in disguise though as with all or most cases because I also got to have the LCD replaced for excessive backlight bleeding (in my opinion), the dead pixel from the previous LCD isn't there anymore (though under the glass there're some smudges but nothing crucial). The backlight bleeding is still the same though in my opinion but at least it's new.
It's a great thing I bought Applecare. I didn't buy it for the iPhone because that's more durable (my iPhone 3G's 3 years old now and it's still solid. Although there are scratches and a crack at the back at the bottom, got sqeezed under the table I think when I sat). I think Applecare is a good recommend for things that get hot like desktop and laptop Macs(are the iOS considered Macs btw?) which are twice or thrice the price of iOS devices.

Qosmio X305 will only boot in safe mode or when the graphics card disabled

Hi All
I am having a very concerning issue with my laptop (Toshiba Qosmio X305). It will only boot in safe mode or if I disable the graphics card.
Awhile back I upgraded the drivers for the nVidia 9800M GTX from the nVidia website, it worked fine for awhile, but then it started crashing randomly by giving me a full screen of random color then switching off. I fixed this by rolling back to the previous version of the drivers (the drivers that came with the laptop software).
After that it working perfectly for months but yesterday my machine started crashing and I could not get it to boot correctly.
I have completely deleted (not just a quick format) both the hard drives that came internally in the laptop and I have installed a clean version (the out of the box option) of the x64 Vista that came with the laptop from the recovery disks I created. After I did the install, it boots fine as only the standard VGA device is used, as soon as I installed the driver off the drivers and applications disk it would not boot correctly:
Just after the status bar comes up and it is about to show the windows logo, just before login, I get a black screen. I can hear that it is booting fine and I can even log in to windows and by memory make things run, but I can't see anything. I then got the latest drivers, again from the nVidia website and they are not helping at all.
My system is as follows (nothing has been added, its is just how I got it):
Vista Ultimate x64
4.00 GB RAM
Intel Core 2 Quad
Like I said previously it is a clean install of the operating system, I have not added any programs, except for installing and then updating the display drivers.
Any help would be much appreciated!

Hi buddy,
It seems that this is a typical example, that only pretested display drivers from Toshiba should be used. Why?
The nVidia drivers are not pretested and they dont have an overheat protection. So for me it sounds like that the nVidia driver has destroyed your graphic card. That means no driver will help you and reinstallation of the whole system too.
I think the only option is replacing the graphic card. Therefore you should contact an authorized service provider in your country. Here you can search:
http://www.csd.toshiba.com
Explain the whole story and then you will see, what the technicians say. If your notebook is under warranty, hopefully this will be covered too. Normally other display drivers you have to install on your own risk
Good luck! :)

Mountain Lion only boots into Recovery mode after using iCould lock

Hi everyone!
I have searched the forums for hours now, but I can't seen to find an answer to my question, so I'd like to ask it.
Recently my system partition failed due to frequent kernel panics caused by a cable in the screen I think. The kernel panics still occur, but I don't know what to do with them.
I managed to save my files and reinstall my osx, which is Snow Leopard (the disc came with the computer). Then I wanted to install my purchased copy of Lion through Appstore, but it said it's no longer available in my country and I couldn't download it again.
Then I decided to buy a copy of Mountain Lion which I tried to install. I managed to do it, and I tried to explore my new operation system.
I tried the iCloud app as well, including the Lock. It locked the computer, and rebooted, but ever since I couldn't unlock it.
When it asks for the password I enter it and it accepts it, but doesn't unlock, only lets me into Recovery mode. Now I reinstalled the whole thing over again and when the Mountain Lion install finishes, it only boots into the Recovery HD without asking.
So if I reboot my computer, no matter what I do it only boots into Recovery Mode.
Please help!!
Mike

I was afraid the Apple Store wasn't going to be an option.
Based on your previous post, I was under the impression you could download Mountain Lion, but when you installed it, it locked up again. Not true?
I don't know how to remove it. You can try contacting Apple support through the link below to see if they can help you get this unlocked.

2011 MBP only boots in safe mode after yosemite update

After attempting to update to yosemite, 2011 MBP (16GB Ram, 1TB HD) will only boot into safe mode. If I reboot without holding the shift key, I get the Apple logo and progress bar ......... that never goes away, just hangs about half way through. Any help?
Dan

Hey there Danielrbjo,
It sounds like you are unable to boot your mac without using Safe Boot. I would use the other troubleshooting from the following article, named:
Mac OS X: Gray screen appears during startup
Disconnect, test peripheral devices and network cables
Note: "Peripheral devices" refers to external devices other than what came with your Mac, such as hard drives, printers, or hubs that you connect via a USB or FireWire cable.
Shut down your Mac. If necessary, hold your Mac's power button for several seconds to force it to power down.
Disconnect all peripheral devices such as external hard drives or printers (leave only the display, a keyboard, and mouse connected).
Disconnect any Ethernet cables.
Start up your Mac.
If you can start up this way, one or more of your peripheral devices (or installed software related to the device) is probably causing the gray screen issue. Connect one device, then restart your Mac to test for the issue. Repeat the process until you locate the device at issue. Make sure the device is powered if it needs to be to operate correctly. Check with the manufacturer of the device for support or possible software driver or firmware updates that may be available for the device. Try a different cable with the device if possible (such as a different USB or FireWire cable).
Note: If you have multiple peripheral devices and the issue only occurs when they are all connected, but not when each device is the only peripheral connected, see the Additional Information section below.
If you are using a desktop Mac with a third-party keyboard and/or mouse device, and the issue still occurs, try starting up with an Apple keyboard and mouse connected instead. Try starting with no keyboard and mouse connected, then connect them after start up. Also, try a different USB port on your Mac.
If the gray screen issue persists with no devices connected, go to the next section (with the peripherals still disconnected).
Reset the NVRAM / PRAM
Shut down your Mac. If necessary, hold your Mac's power button for several seconds to force it to power down.
Reset the NVRAM / PRAM.
If the gray screen issue persists, go to the next section.
Remove third-party RAM and internal hardware
Remove any non-Apple RAM or other third-party hardware upgrades (such as expansion cards or third-party optical drives or hard drives, if present) to help isolate the issue. This is necessary to get as close as possible to the original factory hardware configuration of your Mac.
If you are not sure which RAM modules or other hardware is Apple or third-party, or if you are not comfortable performing these steps, or if you have a Mac mini, consider contacting an Apple Authorized Service Provider for assistance. Otherwise, perform these steps before going to the next section.
Shut down your Mac. If necessary, hold your Mac's power button for several seconds to force it to power down.
Open your Mac to access the memory slots. Refer to the User Guide that came with your Mac, or search Apple Support Manuals for a PDF copy of your Mac's User Guide.
Remove any third-party RAM that has been installed.
Reinstall the Apple RAM that came with the computer if available. Note that Mac OS X 10.5 requires 512 MB or more of RAM; Mac OS X 10.4 requires 256 MB or more of RAM.
If your Mac starts up with only Apple RAM installed, contact the vendor of your third-party RAM.
If you have installed a third-party drive, ensure it is running the latest firmware. Otherwise, reinstall the Apple drive that came with the computer if available.
Thank you for using Apple Support Communities.
All the best,
Sterling

Only boots in safe mode

Macbook air only boots in safe mode, and if I PRAM, the password for the mac does not work

When you can boot in safe mode, that usually indicates that you have something in your login items that is causing a problem. One way to address this is to boot in safe mode, go to system preferences, users and groups, and on your normal login ID, look at login items. Write down what they are, then start eliminating them one at a time, and reboot normally. Fixed? No? Boot into safe mode and repeat.
While you're in System Preferences, there may be programs listed at the bottom of the window .... you want to ensure those are the 10.7 compatible versions of those programs, otherwise that could cause issues too.
This will tell you more about what you're doing with a safe boot: http://support.apple.com/kb/HT1564

24" iMac will only boot in safe mode

Here is the short version:
I have a 24" iMac Core 2 2.16 GHZ with Lion installed (has been for a long time). It will only boot successfully in safe mode. The AHT Extended tests do not report any problems. I have reset PRAM and SMC. Nothing helps. Normal boot process will get to the point where it switches from the Apple logo with spinning wheel to where it would normally switch the OSX GUI and login screen. Instead the screen is all white or gray. The exact same problem happens if I try to boot from an OSX Install DVD or USB and also my DiskWarrior DVD. Since safe mode works, my guess is that the problem is with the video card and the normal color depth that the Mac boots to. In Safe Mode it is in reduced colors.
Since safe mode works, I have all of my data backed up to an external drive. If I could boot from an install disk, I would have already wiped the disk and done a new install, but I cannot do this! I am assuming this is a hardware problem and given the age of this iMac I am out of luck. I ordered a new system last night, but if it is possible to get this one working again, I would like to be able to give it to a relative who could use it. So if anyone has any ideas, it would be appreciated.
Just slightly longer version:
Been using this system since 2007. Used to use it for work, now it is the home media hub where we sync our iOS devices. It has had Lion installed for probably a year now and has always worked great. A few weeks ago, it started locking up whenever my son was playing Minecraft. I would have to power off the system to get it back. I assumed it was a Java problem. I tried fixing disk permissions etc. but nothing solved it. Anyway, last week I was downloading App updates in iTunes when the system locked up again. The mouse would move around but I could not Force Quit anything or really do anything. So I had to power off the system. That is when the boot problems started. Since that happened, the system has not come back with a normal boot.
Thanks for any ideas/help. If someone thinks this is fixable, I can bring it to my local Apple service dealer. I do not want to pay them $100 just to have them tell me it cannot be fixed or needs a new logic board or something like that which would not be worth buying.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in safe mode.
Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.
The commands may line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then either copy or drag it. The headings “Step 1” and so on are not part of the commands.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click the line of text below to select it. Copy the selected text to the Clipboard (command-C). Then click anywhere in the Terminal window and paste (command-V).
find /Sy*/L*/Ex* -type f -name Info.plist -exec sh -c '/usr/libexec/PlistBuddy -c "Print :CFBundleIdentifier" "$1" 2> /dev/null | egrep -qv "apple|Accusys|ArcMSR|ATTO|CalDigit|HighPoint|hp-fax|JMicron|print|SoftRAID|stex" && echo ${1%*.kext/*}.kext' {} {} \;
Post the lines of output (if any) that appear below what you just entered (the text, please, not a screenshot.) You can omit the final line ending in “$”.
Step 2
Repeat with this line:
ls -1A /e*/mach* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts 2> /dev/null
Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting.
Step 3
osascript -e 'tell application "System Events" to get name of every login item' 2> /dev/null
Remember, these steps are all copy-and-paste — no typing. Also remember to post the output.
You can then quit Terminal.

Intel Mini will only boot into safe mode - hangs on ANY Mac OS volume

I have an Intel Mac Mini... the core2duo 1.83GHz or whatever.
I acquired it from it's previous owner, as it was "broken".
He could not get it to run an install disc.
It will not boot any of the Mac OS install media (DVD or CD - 10.4, 10.5, 10.6).
It will not boot/install a Linux disc (I haven't tried, but that's what I was told).
It WILL boot/install Windows !?!?
So... anyway, I removed the HDD, and installed OS 10.6 Leopard on it (FW Target mode installs kept failing at the end - regular retail DVD). I then reinstalled the HDD back into the machine.
The system keeps hanging at the same point it would when trying to boot an install DVD - after the screen turns blue, it goes back to the gray screen, then immediately freezes.
However, I eventually discovered that it WILL boot into safe mode !
Everyone kept saying it's the logic board failure, but if it boots into safe mode, can that be true ? It doesn't seem to me that it would be hardware based in that case - unless it's just a specific component, like the Airport module or something.
The last line displayed in Verbose mode when it hangs is:
"athset_txchainmask[5124] sc->sc.config.txchainmask 5 mask 5"
It also says something about the Airport just before that.
I tried removing the Airport module and it still hangs.
I also tried different RAM, with the same results.
I ran the 10.6.2 combo update in Safe Mode. It still hangs. Haven't tried 10.6.3 yet, though I do have it downloaded and ready to install.
This thing is driving me crazy. Please tell me there's a fix, OTHER than replacing the logic board ?!?! It just doesn't seem like it should be so complicated considering that it runs in safe mode.
It's rare I can't figure out a Mac problem - please help !

Very strange, and getting stranger !
Ok... so, from safe boot mode, I installed Windows XP Pro using the boot camp assistant.
Everything installed perfectly. I started up from Windows, and put in the Mac Mini recovery disc, in order to load the drivers. The Boot Camp software started with Auto Run, and I clicked through to install everything. The drivers start loading...Windows reacts positively, with the system tray announcing "new hardware installed" every 30 seconds or so. Airport/WiFi IS working (in Windows), as it detected my router/network...this is where it gets F'ed up - when the installer gets through with the drivers, and installs the boot camp software for Windows - the system reboots, goes through the usual Windows startup...the desktop background appears, but no icons or start menu - then it reboots again...same thing, again, over and over in a loop.
Went back into OS X (safe boot mode). Installed reEFIt (a bootloader utility), to see if maybe I can bypass the Mac OS/Boot Camp bootloader. No luck. Install worked, but still had the same issues.
For the heck of it, I try installing Linux Mint 8. The live CD starts up OK, but only as far as the boot menu. I tried the installer first - after the splash screen, it hangs on a plain gray screen (w/o the normal linux installer language selection menu - just solid grey).
I tried running the live CD w/o the installer - the actual OS. Same thing - after the splash screen, it hangs, only it's a black screen this time. If I use verbose mode, it still seems to hang on the WiFi card.
Here's the strangest thing yet - Ok, remember, it wouldn't boot normally into ANY Mac OS volume - including the installer DVDs - only in safe boot mode...
So, I try the "hackintosh" IPC osX86 10.5.6 DVD - it boots into the installer with NO problem, WITHOUT safe boot mode ! I tried installing it unsuccessfully. I forget now which options I choose, if any, though I may try it again later and pretend it's just a non-apple PC with the same specs as the Mini (or try just the "base system", and the bootloader - then run the official Apple updates)
This last thing really makes me think it has something to do with the EFI/bios - however, I've only been able to find info on how to update it, not replace or restore it - and it's only from a working install, not forced from a flash drive or CD (plus when I do try the installer from safe boot mode, it says it's current and unneeded).
I still haven't changed the hard drive. After almost successfully installing Windows, I made the assumption the -hardware- was OK, and reassembled everything.
Currently, I'm trying a direct installation of Windows XP Pro SP2 with which I'll try installing the drivers WITHOUT the boot camp software, to see if the WiFi (Airport card) and everything else is indeed working OK (remember too that the system passed ALL the ASD 3S116 tests).
So anyway, that's the current status. Any new ideas anyone ?
Thanks.

Only boots into Safe Mode

My iMac will only start up in Safe Mode. When I restart it normally, I get the white screen again.
Any idea what's up with it?

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of the script have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report what happened. No harm will be done.
12. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

MacBook Pro (Mid 2010) will only boot in safe mode.

I've been unable to boot my MacBook Pro normally. It will boot in safe mode, and, until today, I was able to get a normal startup after resetting both PRAM and SMC. Running "Repair Disk" on the startup disk did not reveal any problems. I have also done a recovery boot to reinstall OS (10.9.1), which did not help either, though I did not wipe the hard disc first (I did back it up).
Had to take it to Apple back in January when the screen started acting funny, i.e. getting static-y and going blank for seconds at a time but then coming back. Their tests showed that there were no hardware problems, and the screen issue was eventually resolved by doing a PRAM reset. About 14 months ago, I had the logic board replaced.
Also, I'm not sure if this is related, but when I have been able to boot normally, if I quit Google Chrome, the machine will freeze completely.
Ran EtreCheck; here's the info from that:

Any ideas are much appreciated!

First try doing a Software Update.
Then restart and see if that works.
If not then I would update Java.
Restart and see if that works.
If not then delete the following plist items.
[invalid] com.oracle.java.Helper-Tool.plist
[invalid] com.oracle.java.Java-Updater.plist
Should find these in:
/Macintosh HD/Library/LaunchAgents
/Macintosh HD/Library/LaunchDaemons
Now restart & see if that works.
If that doesn't work try deleting everything in:
/Macintosh HD/Library/StartupItems
Hope this helps.
