Boots only in Safe Mode - Macbook mid 2007

My Macbook mid 2007 with Snow Leopard will not boot correctly. The only successful means is Safe Mode (key S during boot).
All measures published in various postings have been conducted without any peripheral devices. These are:
verify harddisc
verify RAM
resetting PRAM and NVRAM
A detailled overview can be found under here.
The existing original RAM and harddisc were successfully tested using a second identical Macbook. A new installation of Snow Leopard on the harddisc using the second Macbook was successful and started in this second Macbook as expected. This harddisc was then inserted into my Macbook, but it would not boot. Hence it is safe to exclude problems with RAM and the harddisc.
Attempts to boot with the Snow Leopard DVD (either via C plus boot or Option during boot and select Install DVD) are not successful. Attempts to boot from an external drive are also not successful. The boot process (regular, DVD, external) progresses to different states including grey screen with Apple and frozen wheel. There is no consistency.
From the various postings I have found and studied along with my numerous tests, I have deduced the following possibilities:
There is a problem with the GPU.
There is a problem with the keyboard (maybe someone spilled something).
I have found numerous solutions for "boots only in Safe Mode". All include booting via Install DVD, but this does not work in my case.
I have exhausted all my possibilities. Hopefully someone can provide more insight.

What I am not able to test is booting with an external CD/DVD drive. However, there is no indication that the built-in drive is malfunctioning.
If you have a second MacBook (#2 working OK), you could use its CD/DVD drive loaded with the 10.6 DVD as the target disk to boot into, as the first Macbook (#1 the troubled one) reportedly cannot see a 10.6 DVD normally.
How to use and troubleshoot FireWire target disk mode
In your case this would be:
With the MacBook(1) on (Host), the MacBook(2) off (Target) connect the firewire cable.
Start the MacBook(2), hold T key to make it the boot drive. It will appear on the MacBook's(1) Desktop.
Insert the 10.6 Install DVD into the MacBook(2).
It too will appear on the MacBook's(1) Desktop.
From the MacBook(1), select Restart and hold down the Option key to select Start-up Manager.
From Start-up Manager, select the 10.6 Install DVD which will take you into the installation.
If this occurs, then you have booted into the install 10.6 DVD, From there you could try and install it, see what happens.
However, if it does not see the DVD disk, then this would indicate a defect in the logicboard (motherboard), though which component I would not guess.
If it does see the DVD, in Macbook (2) and can boot into it,… I'd be surprised!

MacPro 1.1 boot only in safe mode with a non Apple display (NEC 24")

Months ago my original Apple Cinema has broken and I subtituted it with a 24" NEC Multisync LCD 2490WUXi with good results.
After some months, for cleaning purpose, I formatted the boot HD and reinstalled Snow Leopard.
Since then I can restart only in safe mode - the DVD also start only in safe mode otherwise after loading the screen is blank and shows only the mouse pointer.
I noted on System Profiler that no monitor is shown and both the DVI ports of the graphical card (NVIDIA Geforce 7300) result not connected!
I have to thing that such a monitor is not known and therefore, as I don't know where get the original one, can I use the Cinema Display 30" (but it has a minidisplay port not present on my card) and how?
Or it is better the substitution of the card having the minidisplay port? What type is compatible with Mac Pro 1.1 (2008)?
Or, in conclusion, I have to trash all and abandon Apple?
Many thanks for your appreciated suggestions.

7300GTs are old in the tooth, there is a Boot Camp related firmware update that you should have seen in ASU.
The ATI 4870 - even flashed PC version - is one option.
I have seen other threads mention 7300.
I'd do the power off unplugged / power button for 10 second "Reset SMC" and see.

IMac 24" boots only in Safe mode

iMac Intel 24" aluminum 3.06 processor, Graphics NVIDIA 8800 GS,from June 2008. Mac OS 10.6.7
It started a few days ago by flickering the upper part of the screen(horizontal strips) during normal use. After reboot the problem reappeared. Ata certain moment the computer would not restart, it hangs at gray screen, butthe hard drive turns and eventually other computers in a wireless networkrecognize the printer connected to the computer.
I tried all usual tricks (starting from DVD or external drive, safemode, single mode, resetting PRAM, unplugging the power cord etc.).
The computer starts only in safe mode, the gray screen becomes blue andthen normal desktop picture. Only some pictures and YouTube videos are not showing up. Safari works only with a single tab, however Firefox opens nearlyall pages.
I took the machine to an Apple shop for repairing. After 11 days theycalled me and said the video card is damaged and should be replaced (some $800). I do not have Applecare and I have to pay the costs. Before agreeing toreplace the video card I would like to know what is the origin of the problem
I wonder why the video card failed. Is it possible that another element(power supply or overheating) has caused the damage to the card? If the videocard is damaged why is it able to handle graphics when the computer is startingin safe mode?

Thank you very much.
In fact it is interesting to know if a video card can be partially dead. If it works (at least partially) at safe mode that means some components of the hardware are still alive. It seems that at starting in normal mode it tries to access something for activating the graphics and it cannot. Are there extra components activated at normal startup, which are not done at safe mode?
I unplugged the computer without holding the power button (At Apple store they didn’t tell me to hold the power button for 10 seconds after unplugging to reset SMC) - also Apple doesn’t suggest to hold the power button, see:
http://support.apple.com/kb/ht3964
I restarted the computer after resetting SMC and it started normally, but after nearly 24 hours the top of the display began to flicker followed by total freeze. After that it couldn't boot in normal mode. It hangs at startup with gray screen. Only in safe mode it can boot.

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.

Powerbook G4 will not boot normally, only in safe mode.

So...about a month ago I updated my powerbook with all the updates that were available, one of the updates was 10.5.8. I came back after the update had run for a while, and found my computer with a black screen, and a faint white bar towards the bottom of the screen. The computer wouldn't respond, and I was forced to do a manual shutdown. The computer would then not boot, instead finally resting on a light blue screen with an active mouse pointer after passing the gray apple screen.
In safe mode, I downloaded and installed the combo 10.5.8 update, but it made no difference.
I assumed it to obviously be a software issue, and so I backed up my info, and reinstalled Leopard. I then updated to 10.5.8 using the combo update. My computer functioned normally for about a week, and then froze, mouse responsive, but nothing else. After manual shutdown, same problem, computer started to blue screen with pointer.
Since that time I've reset the PRAM, run disk utility a million times (no errors), repaired permissions, all to no avail. I've run the Techtool diagnostics on it, and it found no hardware failures. The computer will not boot from an external hard drive, ruling out the HD.
I've replaced the RAM with different RAM, again will not boot. The computer boots without fail every time in safe mode.
History on my computer, one of my memory slots failed to recognize memory any longer, and my logic board was replaced a little less than 2 years ago while I still had applecare.
So to sum up:
Powerbook boots only in safe mode
Stays at blue screen with mouse pointer when booting
May work properly for a few days after erase and install of OS, but then fails again with same systems shortly thereafter
Any ideas???

Have you tried running the Apple Hardware Test from DVD?

My Macbook Pro won't boot up, only in safe mode!

Help, my macbook pro won't restart, only in safe mode! and it seems that safe mode has plenty of implications for use. my usb memory stick doesn't seem to be recognized while in safe mode. I was doing a cleanup on mackeeper just after I downloaded a trial version of microsoft office mac. The trial wouldn't work properly so I deleted it and decided to do a cleanup with mackeeper. than the mac froze while mackeeper was doing it's cleanup and the screen flashed black a few times. Ever since it won't boot up unless I use safe mode. Also, I downloaded the most recent updates while in safe mode but it doesn't seem to be recognizing that I already downloaded them because software update is still telling me that I have 6 updates. So I am horribly confused at this point. Please help, I need this laptop to do report cards (it's a good thing I got an extension). thanks

Tecra 8100 only boot up in safe mode

I seem to have lost the display drivers to my Tecra 8100.
Since I attempted to use an extra screen which worked fine until I came to boot up the following day when it would only boot up in Safe Mode.
What have I done wrong and how can I rectify it?
Driver detective doesn't work, just comes up as having performed an illegal action.

Lars,
I'm afraid that it seems that Toshiba no longer provide the drivers for the Tecra 8100 as it's such an old computer, around 12 years old. I have been on the Toshiba website and tried again on the site you suggested but to no avail. Sorry about that but am still hunting.

Best RAM configuration for Macbook (mid 2007)

Hi, I have a Macbook (mid 2007) with 1 GB ram and I would like to upgrade. Currently I have 2x512MB, so both of my memory slots are taken. Is it a good idea to have one 512MB card and a 2GB card in the other slot? Otherwise, what is the best RAM configuration for a mid 2007 macbook?
I am also looking into purchasing this memory card for my macbook, is this a good choice?

Any advice would be very much appreciated!

In doing a Google search for that article I saw, I found this:

the maximum amount of RAM your laptop can take is 3.3GB. So while you can physically insert 4GB of RAM, OS X will only be able to see 3.3GB of it.
But I don't know how knowledgeable that poster is who says it can utilize 3.3 GB. I do know that the full 4 GB shows up in the System Profiler on my MacBook Core 2 Duo 2.16 GHz.

Powerbook G4 only start safe mode

Hello i have powerbook g4 with cpu 1.25ghz. I use to have mac os4.1.1 installed. Lately had freexing problem and as it was a very old install i tried a fresch install. I downloed os as i lost my original dvd. Tried 10.4.3. Install go fine but never start when it finish. Only in safe mode will start. What could i check?please help

When there is a problem with an OS X, such as those usually installed from DVD system media
you would need to use the boot-able install-restore DVD (or later retail DVD, if not original grey
color label discs) to see about repairing the problem. You cannot update or upgrade to make a
problem go away. And an offer/download of a complete OS X system (torrent?) is not legal.
With an older computer, there is a fair chance the original hard disk drive may be failing; so that
is something to think about when you have an internal hard disk drive that spins thousands of
rotations per minute and gets written to & read from millions/billions of times a year....
The download update is only a minor step, and if you chose to download that from somewhere
other than the Software Update (via computer access to Apple Server) the actual one to seek
if everything was in great shape with your computer, would be the Combo 10.4.11 last update.
These steps are considered updates & not upgrades. The distinction is more than a word deep.
You will have to locate the correct DVD install media since a download from the internet of a
complete OS X Tiger 10.4 system is not available online; anything you may find very likely is
an illegal download and may be full of bogus content, such as malware or missing files, etc.
Apple no longer sells these discs, you may contact Apple sales support and have your product
serial number (PowerBook G4) available to ask an OS X specialist, if it is possible to get some
kind of operating system install DVD for that old a computer. The newest it could run would be
Leopard 10.5 (install from DVD, then download update to 10.5.8) however the Tiger 10.4 DVD
may be an expensive item if you look at Amazon or eBay sites online. Expect to pay...
You may have some luck if there happens to be an Apple User Group in your locality or if a
school or university has a computer lab and has not cleaned out their archive of old OS X.
School rummage sales, second hand shops, and other local finds are random luck events.
Good luck & happy computing!

G4 powermac will not boot up nomally unless i boot up in safe mode help ?

My G4 power mac will not boot up when switched on itakes several re boots and somtimes crashes.
Will boot up in safe mode. but this only allows me to use some of the application software i need and not all of them.
Can anyone help I thought it could be the hardisk but why would it boot up in safe mode?

Boot from the Tiger installation disc 1 (hold down 'C' on startup). Don't touch the installer, go to the menu bar and select Disk Utility (I think it's in the Tools menu on Tiger).
In DU, select your internal drive in the sidebar (the top item with the makers name and serial no.). Run Repair Disk.
If problems are reported, run it again until the green message says the disc seems to be OK.
Quit DU, quit the installer and restart.
If DU says there are problems it can't fix, you may need DiskWarrior.
Either way, let us know the results please.

Nominal/Original battery charge capacity of genuine batteries for 13'' macbook (mid 2007)

Hello everyone,
I just wanted to ask which is the nominal battery charge of a genuine (from Apple) battery for a 13'' macbook (mid 2007). I have just bought a new one, and it has a nominal capacity of about 5500 mAh. I just would like to check if it is in good condition.
When my old battery stopped functioning I checked some information in the web and arrived to the followings conclusions:
Webpages:
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batterie s
http://www.apple.com/batteries/notebooks.html
Conclusions:
- Lithium-based batteries have no memory charge effect. This means, that you don't need to be careful about charging-discharging the battery to 100% and 0% sometimes every 3 months. It also means that you can keep the battery in good health conditions not charging-discharging it at all.
- When you are not going to use your notebook for some months it is best to keep the battery at 40-50%charge (it radically increases your battery lifetime).
- It is also good to keep your battery at "low temperature" when not using it. It seems that 0-20ºC is ok. For example 40ºC is really bad for your battery.
If anyone has any comment about my "conclusions", it will be useful form me .
Thanks for the information in advance,
Jesus

Call Apple Customer Support 1-800-767-2775 (telephone numbers for other countries - http://support.apple.com/kb/HE57). Provide the serial number and specifications of the Mac. They may be able to provide a replacement set of discs for a fee. These discs will be for whatever OS was installed on the computer originally, so if you have an upgraded version you will need to obtain the discs some other way.
You may want to just upgrade to a newer system version. Snow Leopard 10.6 would be a good one for that computer but you would need to make sure it has enough RAM to run it. It would only cost $29 to get Snow Leopard from Apple and for the next 30-45 days until the next OS release in July it is still relatively up-to-date.
Get more information about your computer. Go to the Apple in the upper left corner of any window, then "About This Mac", then "More Info..." Copy and paste the information here, but omit the serial number and Hardware UUID (if present).
Snow Leopard 10.6 Technical Requirements - http://support.apple.com/kb/SP575 - note by K Shaffer - http://discussions.apple.com/message/12921514 : "Some early Intel-based Macs can't use Snow Leopard 10.6 installers; of those, the Core Duo (not 2 duo) were suspect and had issues." - and a qualifier by "a brody" http://discussions.apple.com/message/13028822 : "I think that refers to the ones without at least 1 GB of RAM."

ALWAYS BOOTS UP IN SAFE MODE

MY MAC ALWAYS BOOTS UP IN SAFE MODE. I REPLACED THE KEYBOARD DUE TO A JAMMED SHIFT KEY WHICH WAS CAUSING IT TI DO THE SAME THING, BUT ITS DOIN IT AGAIN. CAN SOMEONE HELP PLEASE?

ACTUALLY IT BOOTS THE RIGHT WAY IF I LEAVE THE KEYBOARD OFF UNTIL THE SIGN IN SCREEN COMES UP. AND YES IT IS A WIRELESS. IF I TURN THE KEYBOARD ON BEFORE I TURN THE COMPUTER ON IT WILL BOOT IN SAFE MODE. IS THERE ANYTHING ELSE THAT I CAN TRY, OR SHOULD I JUST SAY FORGET IT, AND WAIT UNTIL THE SIGN IN SCREEN COMES UP BEFORE I CUT IT ON?
