My MacBook Core 2 Duo will not boot up. In safe mode I see keychain problems and Mach 1102.

My MacBook Core 2 Duo will not boot up. In safe mode I see keychain problems and Mach 1102 and it keeps circling through the same error. Also the screen is so faint (pressing the F1 and F2 keys don't do anything). I got this from a friend and he didn't have any of the original discs. Any suggestions? From what I've read it's a problem with a recent update. I've never had a Mac so I'm trying to learn and fix it.

I just had an issue like this. I was able to boot up with an external firewire drive, although it was a lot of trouble. I think doing an option boot finally worked; holding down the option key, I eventually got to see the firewire drive was bootable, and booted from it.
I put the thing in verbose boot mode (command - v , I think; but please look it up. I have no Mac books at work to check). In verbose mode, you could see that the hard drive could not mount; the OS tried to do fsck, but it failed around 2/3 of the way, and the CPU was halted.
I was occasionally able to boot normally, but never in safe or single user modes; these do a disk test first, which invariably failed.
I could see from the system and console logs when I managed to get the firewire boot going that there were repeated errors trying to access drive s03, the internal SATA drive. The logs on the SATA drive showed huges numbers of errors. At a wild guess, for some reason a lot of sectors went bad all at once. There had been a some erratic behavior before, but I'd put that down to the single processor G5 problems. (these were non video related, just freezes).
Applecare wanted me to carry the huge thing into the local Apple store, but I persuaded them to just send me a replacment hard drive, which they did. The new one works perfectly.

Macbook Pro 15" will only boot up in Safe Mode - Please help!

My Macbook Pro will not boot up normally. It goes past the screen with the apple and the wheel and then just stays white. Also on the screen there are little rectangular blocks going across diagonally. In Safe Mode, it boots up but with little square blocks going across the screen. Can anyone help please?

Firstly, see this article: Mac OS X- What is Safe Boot, Safe Mode? and this one: Gray screen appears during startup.
Secondly, try the following:
Delete caches to resolve some startup problems:
Boot into single-user mode. After startup is completed you will be in command line mode and should see a prompt with a cursor positioned after it. At the prompt enter the following then press RETURN after each commandline:
/sbin/fsck -fy
If you receive a message that says "***** FILE SYSTEM WAS MODIFIED *****" then re-run the command until you receive a message that says "** The volume (name_of_volume) appears to be OK." If you re-run the command more than seven times and do not get the OK message, then the drive cannot be repaired this way.
If you were successful then enter:
/sbin/mount -uw /
rm -rf /System/Library/Caches/*
rm -rf /Library/Caches/*
reboot
I suggest you print out the above to be sure you do not make any errors when entering the commands. When in single-user mode you have 'root' access, so it's important that you not make any mistakes.
Lastly, reinstall Snow Leopard if the above doesn't help. This will not erase the drive.

Will not boot up in safe mode

Here's another headache which is testing my temperament to the extreme.
My Mac crashed this morning and when I restarted I got the classic Spotlight in the corner icon. The usual procedure here is to restart in safe mode, empty the wastebasket and then restart as normal.
Unfortunately, my Mac simply refuses to boot up in safe mode! Instead it shuts down. Now this is nothing to do with me leaving on my finger on the button too long or not long enough, as I've done the safe mode restart countless times...the bugger just will not go into safe mode no matter what I try and do.
Any insights would be greatly appreciated before my full head of hair turns into a massive bald patch!!

MacBook Core Duo will not load pages on known working router

I've got the original Core Duo black MacBook running OS 10.6.5 that's having problems with Wi-Fi. It will connect to networks at my school, but at home, it will connect (very slowly) to my Linksys G Router that works with my phone, my iPod touch, and my Early 2008 Aluminum iMac (OS 10.5.8), but it refuses to load web pages in Safari or Firefox, as well as it will not load the iTunes Store. If I turn on Internet Sharing at the iMac, I can use that signal to access the internet. This is not a distance issue as it has worked well in the past and the router is right next to the iMac I am using for Wi-Fi right now. I have had the issue before, but it wouldn't load pages from any Wi-Fi source, so I replaced the AirPort card with a genuine Apple 802.11N card, thus resolving that issue. I have tried resetting the router and the modem, but this has not helped.
Thanks in advance.

Have you checked for firmware updates for the router?
If you connect to the router via Ethernet, can you get to the Internet without issue?

MacBook Pro will not boot, only in safe mode. Tried Everything!

My MacBook Pro was working fine yesterday. Went to boot it up today, and it freezes on the Apple grey boot screen, will not progress further.
It does however start in safe mode, but will not start normally.
I've tried everything I can find, reset the PRAM, reinstalled OS X, ran the Apple Hardware test which came back clear, I don't know what else to try and why it's not working. It's been fine until now. Please help! Thank you

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.
Some of the commands will 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 copy it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
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 (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click the line of text below to select it:
for k in /Sy*/L*/Ex*/{,.?}*.kext; do test -f "$k/Contents/Info.plist" && /usr/libexec/PlistBuddy -c "Print :CFBundleIdentifier" "$_" | egrep -qv "apple|Accusys|ArcMSR|ATTO|CalDigit|HighPoint|hp-fax|JMicron|print|SoftRAID|stex" && echo $k; done | open -f -a TextEdit
Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). A TextEdit window will open with the output of the command. Post the contents of that window, if any — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
Step 2
Repeat with this line:
sudo defaults read com.apple.loginwindow LoginHook | open -f -a TextEdit
This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step.
Step 3
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 | open -f -a TextEdit
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 4
osascript -e 'tell application "System Events" to get name of every login item' 2> /dev/null | open -f -a TextEdit
Remember, Steps 1-4 are all copy-and-paste — no typing, except your password. Also remember to post the output.
You can then quit Terminal.

2007 Mac Pro will not boot, even in safe mode

Hello,
I have a Mac Pro purchased in 2007 that had been working well up until a few months ago. I had trouble with Microsoft Word 2008 repeatedly crashing; I repaired the hard disk and moved up to Word 2011, and the problem seemed to resolve.
Yesterday, the machine crashed, and I am not able to start it up, even in safe mode. I have tried resetting the SMC and NVRAM/PRAM, removed and cleaned the graphics card (NVIDIA 7300 GT), and removed the 3rd party RAM I installed at least 2 years ago.
When booting to the internal hard drive, the Apple logo will show, then a blue screen followed by a gray screen with a frozen cursor. When I boot to an external hard drive or the OSX Leopard install DVD, the screen flickers like below:
When I tried to boot in safe mode while holding shift + command + V, the safe boot froze after reading:
panic (cpu 2 caller 0x2abf6a): kernal trap at 0x0029a4bc, type 14= page fault, registries:
[4 lines of 2-3 letter acronyms and numbers]
Error code: 0x00000000
I am thinking of buying a new graphics card (ATI Radeon 5700), but I want to be sure (as much as possible) that will solve the problem I am having. Any suggestions would be very much appreciated!
Thank you,
Cheryl

replace the system drive
always clone your system
yes dump the 7300 if you plan to keep using it and use Lion
A clean install would be nice start, on say 120GB SSD or something too
And 2x2GB FBDIMM set is $30 if you need a set
AHT is on your OEM DVD from 20007
dust, temps and air flow is also important

Macbook Pro intel core duo, will not boot to anything.

Greetings, I am currently having issues with my MacBook Pro. I get the flashing folder with the ?, but I can't boot to any of the startup utilities. I have tried all that I have read about on other posts, such as, trying to boot with the C key held down (it just gets to the folder ?), booting to disk utility didn't work ( held down keys and it went to the folder ?), I also tried getting to the hardware test, by holding D and having the applications disk in. And still everything I try gets me to the flashing folder ?. Also I do have the CD's that came with the laptop and tried to install from the mas os install CD and still get to the flashing folder ?. The reason it started doing this was because of this...... I had boot camp installed and was running dual boot with windows 7, then I had deleted the mac osx on the drive so I would only be using windows 7. I wanted to reformat the drive after this, but had a hard time finding out a way to actually do this, as the MacBook unlike PC's, doesn't have any BIOS, and at that time didn't know all the key commands to use at startup. So I downloaded a program from the net that can run at windows start and delete the HD before the computer fully boots windows 7. So after I deleted the HD I could not install any program or start any of the mac utilities at startup, and I did the PRAM reset, still everything that I try it gets me to the flashing folder ?, in the end. Could I have deleted all of the startup utilities when I wiped the HD? If so how can I get these back on my MacBook pro if I can't get the MacBook pro to read any files or start up utilities? Any help would be greatly appreciated.

UPDATE: I found a way to download firmware, I thought that it could be the reason I get the flashing folder with ?, because maybe I somehow damaged the firmware on my computer when I did the reformat. Alas I followed the directions to re-install the firmware and still I get to the same flashing folder. I used FirmwareRestorationCD1.4 I think it is the one I needed for my model, MacBook Pro 15" intel core 2 duo, and comes with osx 10.5 leopard I think, the OSX CD is stamped 2008 for 15" MacBook Pro. I can't check the properties of my MacBook because it has no programs on it, but this is what I think it is from memory and deduction. Well now I guess I have to ask the question, is the firmware the programs installed such as disk utility, and recovery mode? I need to read more I guess, and also I thought I needed to take the 1.4 off the end of the FirmwareRestorationCD in order for it to work, but the instructions for making and using the firmware CD is a bit vague. Another factor in this to make things more difficult, is that this computer is my second computer and it's a PC laptop, so I used a program download from the net to write .dmg files to disk, it's called Transmac, could this be another fault in my creation of the CD? I am out of ideas again as to what I need to do to get mac OSX back on my computer, I am still a bit new to the way macs work, so I could definatley use some advice. thanks.

If you are running Snow Leopard:
Reinstall OS X without erasing the drive
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.

HT1455 What if my computer will not start up in safe mode? What next?

What is the remedy for a MacBook that will not start up in safe mode? The gray apple icon and progress wheel appear, I let go the shift key and the whole thing shuts off again. Please help. Thank you.

My understanding is that the Apple logo is produced by the disk and the spinning wheel shows that the software boot process has started.
1 - Shut down your Mac
2 - Press the power button to start and
3 - Immediately press and hold the Command (Apple) key and the S key
4 - At the prompt type the following and then hit return:
/sbin/fsck -fy
fsck will go through five "phases" and then return information about your disk's use and fragmentation. Once it finishes, it'll display this message if no issues were found:
** The volume (name_of_volume) appears to be OK
If fsck found issues and has altered, repaired, or fixed anything, it will display this message:
***** FILE SYSTEM WAS MODIFIED *****
Important: If this message appears, repeat the fsck command you typed in step 4 until fsck tells you that your volume appears to be OK (first-pass repairs may uncover additional issues, so this is a normal thing to do). When fsck reports that your volume is OK, type the following at the prompt and hit return:
reboot
Your computer should start up normally and allow you to log in.
Good luck.

Iphoto book will not upload even in safe mode when trying to buy book, any suggestions on how to complete the "BUY BOOK" process?

Make a temporary, backup copy of your library if you don't already have one (Control-click on the library and select Duplicate from the contextual menu) and apply the fix below:
Fix #1
Launch iPhoto with the Command+Option keys held down and rebuild the library.
Since only one option can be run at a time start with Option #1, followed by #3 and then #4 as needed.
After each run thru the repair process see if you can create a PDF file of the book as described in this Apple Document: iPhoto '11: Preview a book, card, or calendar before you order or print it. If you can try ordering the book. If you can't finish trying all of the otpions and then boot into Safe mode and try there.
