IMac G4 will not start up from OS disk to upgrade

I am trying to upgrade the OS in a G4 iMac, the OS disk is recognized, am asked to restart, but it will not restart from the OS 10.5 disk.

Will it boot from the install disc that came with the G4? If so, run
Disk Utility
   1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
   2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
      Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
   3. Click the First Aid tab.
   4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
   5. Select your Mac OS X volume.
   6. Click Repair. Disk Utility checks and repairs the disk.
After that, reset the PRAM and see if that helps.
Please post back with results,

Help!!! My iMac will NOT start up from any disk!

I was attempting to delete some files that had been in a separate partition on my older TM backup, in order to copy it to my new 2TB external drive. (The first time, it copied it as two partitions, which was NOT what I wanted! It worked fine, except that it needed more room already!)
In retrospect, these files appeared to be an alias of all my system, application & user folders. which I was unable to trash, but was able to trash most of them individually. Big mistake!
My iMac is getting a "?", a file icon and a 0 w/a line through it.
So, I apparently have all these key folders in my trash (I was unable to get rid of them). Unfortunately have been unable to start it with either of my two TM drives (both had been unmounted), nor my cloned drive, nor my OS install drive or any other utility drives.
Any suggestions to try before I bring it in to my local Apple store?
Thank you!
PS- I just heard of Steve Jobs death, and am so saddened to hear it...

I said "My iMac is getting a "?", a file icon and a 0 w/a line through it."
I should have included the folder icon that alternates w/the above two ...
Please! Any help (and/or suggestions) is appreciated!

Imac G5 will not start up correctly? invalid directory count 52 instead of 53

Hi, i have a Imac G5. it had been working fine for many years untill a year or 2 ago when it stopped all of a sudden and just would not start up as it should. instead, it went to this grey screen with horizontal lines. eventually after trying just about every combination of keys held down on startup, the only way i could get the mac to restart was by starting it in safe mode. (at this point i rescued all my photos and music and moved them onto my macbook pro) i thought it was working fine in safe mode untill i realised that it could not connect to the internet, the sound would not work at all, and when i went to preferances it could not find any output device for the sound. it also keeps coming up with a message saying that my internet communication device does not exist. allot of the programs worked fine, such as word, or photoshop, whereas others would not. i verified the disk, and discored that it would not let me repair it.
Invalid directory count
it should be 53 instead of 52)

it then came up with a message saying that he disk utility stopped verifying the macintosh hd because of it reporting the failure on exit.
i have tried doing this a few times but the exact same result is gained
i tryed using disk repair whilst starting up from the original install disk, but this also did not fix the problem. eventually, i decided to reinstall the os x 10.4.11. this had absolutely no effect, and i am at the same point. i would be very gratefull if anybody would be able to come up with any ideas of how i could fix this problem?
additional details: i have tried using the proxy reset
i have also tried running a apple hardware test
i have tried repairing the macintosh hd disk using the original install disks
also: all of the sockets at the back work fine, e.g. usb, but the microphone and headphone sockets do not work.
it will read disks fine

but this also did not fix the problem. eventually, i decided to reinstall the os x 10.4.11. this had absolutely no effect,
I'd have guess you reformated at that time. The file system is messed up. You need to reformat.

IBook G3 will not start-up from 10.4.6 Install disc

I have a 700 MHZ iBook G3 with 640 MB RAM and it runs without problems on 10.3.9
I would like to upgrade the system software to Tiger, but any attempt to start-up from the 10.4.6 install discs that came with my Intel MacBook result in the grey screen with the power icon that reads in multiple languages "You need to restart your computer. Hold down the Power button for several seconds or press the Restart button."
Additionally, that message is partially obscured by 24 other lines of code, starting with "panic(cpu 0 caller 0x002E0BF4): Unable to find driver for this platform: "Powerbook4, 3"." and ending with "panic: We are hanging here. . ."
Am I doing something wrong? Are there other methods of achieving this?
If the 10.4.6 install discs that came with my MacBook are unusable to update the iBook OS, what are the other options to upgrade it to a version of Tiger?
thank you!

On ebay, there seem to be mainly single DVD full-install 10.4 versions which indicate "Includes Xcode 2" on the DVD.
there was only one 4-disc set I found and it states:
"By default, Apple only sold Mac OS X 10.4 Tiger on DVD. When Tiger first launched, Apple offered the opportunity to trade the DVD in the retail box for a CD set using a media exchange program. Most Mac OS X Tiger installer discs sold on eBay are model-specific, that is, they shipped in the box with a specific Mac. This is the full retail set that could only be obtained through the Apple media exchange program that no longer exists. It is difficult if not impossible to get this CD set from Apple today."
Is this the specific version I need to properly install Tiger on my G3 iBook or will one of the single DVD full-installs be sufficient? (this box set is alot more expensive than the single DVDs)
thanks again for the help!

Will not start up in Target Disk Mode

I recently purchased a MacBook with Leopard. I'm trying to use the Migration Assistant to transfer old stuff from my G4 867 with Tiger to my new MacBook. I have connected using a firewire cable and going through the MA software. It advised to restart the old computer holding down the t key. I have tried this numerous times, old computer starts to start up, then shuts down. I even attempted to change the settings in System Pref=>Start up Disk and starting in TDM, computer attempts to restart, then shuts down. Can't seem to get the old computer to start up in Target Disk Mode. Any suggestions?

I just tried starting it up with option down and it did come up with the System icon and the two arrow icons, then let me continue with start up as per normal by pressing Enter.
When I hold down the T key, or choose Terminal Disk Mode in the System Prefs: Startup Disk, it restarts, then shuts off after about 10 seconds.
I tried disconnecting the two CD drives (ribbon cables) just to see if they were interfering somehow - no go, same problem. Now System Profiler shows only a single ATA bus containing a single Hard Drive at Unit:0, and it still won't go into TDM.
The hard drive is a Seagate Barracuda ST380021A, which has this for pin configurations:
Seagate ST380021A jumper diagram
Originally it was in the Cable Select position, but now it is in the Master/Single drive position (pins 7 & 8).

MacbookPro will not wake up from sleep after memory upgrade

I am restarting this topic as I have read thread after thread (many years old) and they all just die off with out any definite solution.
I have a 13" Mid 2010 Mac book Pro which originally came with 250gb HDD and 4gb memory
I have recently upgraded to a 256 SSD and a 1TB HDD optidrive replacement along with a 8GB memory upgrade and I am now running Lion 10.7.4
If I close the lid and open within approximately 1 minute it will wake up quickly as normal, if I leave it asleep for a minute or 2 it will not wake up with out holding the power button for several seconds and then I still need to wait a several seconds for it to respond and actually wake up. Sometimes I will need to completely shut down and restart. If I wanted a computer that takes forever to wake up I would have a PC!
The last thing I upgraded was the memory so I am sure it is the cause of the sleep problem and not the SSD conversion which was working fine with the original 4GB mem before upgrade.
I have read about resting the PRAM, resetting PMC as well as executing a line in the terminal, but all of these seem to have variable success. I have tried every thing but using the terminal to adjust the hibernate mode setting as I am not proficient with terminal and don't actually understand what changing this setting does (sudo pmset -a hibernatemode 7).
Has anyone resolved this sleep problem and what did you do? I would greatly appreciate some knowledgeable insight on the hibernation settings, and what running the line in the terminal is actually doing... even better what is the default so I can change it back if it doesn't resolve the problem.
A simple memory upgrade causing such a issues is very irritating.... Any help would be greatly appreciated!

But still, the sleep issue persists, so it is a more subtle timing issue. I upgraded my MBP with a Corsair 8GB kit ( http://www.corsair.com/us/corsair-mac-memory-8gb-ddr3-sodimm-memory-kit-cmsa8gx3 m2a1333c9.html ) and it indicated it had 9-9-9-24 CAS timing. It has worked flawlessly till now. Note that my Mac is a Late 2011, whose memory runs at 1333 MHz.
As far as I can tell, the 13" Mid 2010 models used 1067 MHz memory with 7-7-7-20 CAS timing: http://www.corsair.com/us/corsair-mac-memory-8gb-dual-channel-ddr3-sodimm-memory -kit-cmsa8gx3m2a106c7.html

PERSONAL WEB SHARING ON iMAC G5 WILL NOT START

hello:
i am hoping someone would be able to help me on this issue. i attempted to start the Personal Web Sharing service on my computer (iMAC G5 with MAC OS 10.4) from System Preferences > Sharing. however, after i highlight Personal Web Sharing on the list of services and click the Start button, the message changes to "web sharing starting up..." and simply remains that way (i've waited for a long time). it does not change to "web sharing on".
am i doing something wrong? is it possible that my Apache installation has been compromised? my goal is to be able to use my computer to create and run .php web pages.
any help / suggestions are greatly appreciated
iMac G5 Mac OS X (10.4.8)

Sorry, this still doesn't seem to be working.
Actually, it's me steering you wrong. It's been a while since I fooled around with the Entropy PHP installation and it looks like he's changed it.
He used to put the configuration stuff for PHP at the bottom of the main Apache config file, but now he's putting it in that separate file in the httpd users directory. That's why moving the default Apache configuration file into place didn't help.
You have two choices: one is to just forget about the PHP5 stuff for now and go with Apple's default PHP install. The other is to try to get PHP5 up and running.
The first option is very easy: just run this command:
<pre class="command">mv private/etc/httpd/users/+entropy-php.conf ~/Desktop</pre>That will put the offending file on the desktop. Now try starting the web server. Most likely, PHP won't work yet, but Apache should start. In order to use the default PHP5, you need to make some changes to the httpd.conf file. You can use pico in the Terminal. It's pretty simple and the key commands are printed at the bottom. Where you see the up arrow listed, that means to use the "control" key, i.e., "control"-x to exit. You need to use sudo, though so you have root privileges:
<pre class="command">sudo pico /etc/httpd/httpd.conf</pre>Search ("control"-w) for "php". The first line you'll see is this:
<pre class="command">#LoadModule php4_module libexec/httpd/libphp4.so</pre>Uncomment it by removing the "#" from the start of the line. Search again until you find this line:
<pre>#AddModule mod_php4.c</pre>Again, remove the "#". Now search again until you find these lines:
<pre class="command"><IfModule mod_php4.c>
# If php is turned on, we repsect .php and .phps files.
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
# Since most users will want index.php to work we
# also automatically enable index.php
<IfModule mod_dir.c>
DirectoryIndex index.html index.php
</IfModule>
</IfModule></pre>Just verify that they look like these. If they don't, copy and paste your corresponding lines into a reply. Now stop and restart the web server and see if PHP pages will work. You should be using OS X's built-in 4.x version.
If, on the other hand, you'd rather use the Entropy PHP5 installation, post back and tell me and we'll see if we can figure out what's up with that...

IMac G5 will not start.

Hello folks, I believe I have quite a tricky problem.
I have an iMac G5 with OS X Snow Leopard (10.5.8) installed. This morning I went to reboot it all and re-install the OS, as it has been a long time since I had done so previously. This carried through well, and I proceeded to run boot camp assistant so as to partition my computer with Windows XP SP2.
It is at this point I should add that my disc drive on the mac is very faulty, and i have been using an external Samsung disc drive to install the software which has thus far seemed readable and compatible.
After putting the XP disc in and commencing installation, the computer restarted and did not recognise the disk. When I tried again, the computer restarted to the point where I was blocked by alternating images of the apple logo and a no permission symbol, as well as the occasional appearance of a folder with a question mark on it.
Now, I really need advice for simply how to get my computer to a point where i can start from absolute scratch. Unfortunately, I cannot do this as I can get no further than the original screen.
I have tried the following:
Pressing 'c', to run through the disk.
Pressing 'x', as to force the start up mode.
Pressing 'shift', to enter safe mode.
Pressing 'cmd' and 's', which supposedly works occasionally.
Pressing 'alt', just in case it was confused between hard drives
Pressing 'cmd', 'ctrl', 'r' and 'p', which again is supposedly useful.
Unplugging from the socket for hours on end.
Unplugging all external connections to the iMac.
I have quite frankly, exhausted all my ideas. If any of you have any insight, it would be greatly appreciated. Remember that my disk drive is external, as i believe that part of the problem rests there.

Hi Aaron,
When the family first got the computer (I inherited it, hence my need to run Windows OS primarily), it had the Tiger OS, meaning I had to install bootcamp separately so as to put Windows on. However, a few years later, we bought the Snow Leopard system and it had bootcamp in the program already, so it just made the process more convenient. As well as this, installing Windows or rebooting it had never been a problem.
Unfortunately, I do not have anything to use FireWire with. I have an iPod, but no other products in which to connect. I say this because somebody said that when they received the rror symbols, connecting it with a MacBook Pro through FireWire seemed to do the trick. However, I do not have this resource at my disposal.
I honestly believe that if my disk drive functioned correctly, therw would not be a problem, but perhaps the Mac can't quite adopt the external drive while in its preliminary loading stages. Getting the drive itself fixed would cost more than the value of the actual computer, so I do not wish to do that.
I am trying to put the disk on a USB, so as to try and reboot it all through that, though it seems improbable. However, I will ddefinitely let you know how that works out.
Thanks for your reply by the way, if you suddenly come up with any new ideas, please let me know!

Intel imac (white) will not start up, please help.

I have a 20" intel imac (white not silver) running 10.6.4.
I can not get it to boot up on its own, the farthest it gets is to the Silver Apple with spinning gear.
I have tried:
1. safe restart - the result is - I get a circle with slash and the a folder with ? and then the silver apple with gear spinning.
2. booting from disk warrior and running it - the result I get is -"The new directory cannot replace the original directory because of a disk malfunction."
3. reinstalling the OS from the start up disk, - the result I get is - "The contents of this disk can't be changed."
4. starting from the OS 10.6 disk and running Disk utilities - the result I get is - "Invalid node structure, The volume Macintosh HD could not be verified completely. Error: This disk needs to be repaired. Click Repair Disk." When I hit repair button I get this result, "Error: Disk Utility can't repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
All of these methods have failed me. Can anyone please help me? I really need to be able to at least recover some files from the imac. That is my main concern at this point.
Thanks in advance.

The problem is I can not get my HD to boot up, I can start up with the install disk but disk utilities can not repair the disk. I can not dragNdrop, it wont let me select files. I can not reinstall the OS because it says their is a problem with my drive. It sounds like I'm screwed but my business related info is to important to just give up.
I was able to make a disk image of a folder that had I few files I need and was able to copy that disk image to my external drive. So I may have to do that (tideous but I am willing to do that to recover the data).
Any other thoughts before I take it somewhere?

Since replacing hard drive, "restore previous session" button doesn't work, can only do it through history tab. Also will not start up from task bar icon.

Hi, been using Firefox for some years, had to replace hard drive recently and re loaded Firefox. Since then, the restore previous session button doesn't work, but I can do it from the History tab. Also Firefox itself won't start from the task bar or desktop, only the start menu.

2005 mac mini on OSX leopard will not boot up from firewire disk

I have an old mac mini that my son still uses and the super dirve does not work any more. But now the main hard disk needs to some attention from Disk Utility. So I need to boot up from the Leopard install DVD. But of course the DVD dirve does not work so how to do this? I have tried to create a bootable disk by restoring the install DVD to a partition on a firewire drive and this is seen as a bootable drive by my 2008 iMac, but not by the Mac Mini. So is it possible to boot up rom a irewire drive? USB doesn't work either

Which Tiger Install DVD do you have...?
1. I think that, that model originally came with 10.4.10 and so you will need either the original 10.4.10 install disc or a later retail (Leopard or Snow Leopard) upgrade DVD.
2. In addition, a new (HDD, Hybrid Drive or SSD) must first be Partitioned GUID Partition Table and Formatted Mac OS Extended (Journaled) before OS X can be installed.

PowerMac G5 will not start up.

Hello,
I have a PowerMac G5 2.5GHZ Dual Processor (June 2004) that will not boot past the grey apple screen.
It will not get to a second chime by holding Command-Option-P-R at startup.
If I start up using Command-Option-O-F and enter reset-nvram (return) and reset-all (return) it freezes.
I have pressed the PMU button once.
It will start up using the hardware diagnostic disk and I can run the extended test multiple times (everything passes). When I press shut down or restart on the diagnostic screen, it freezes.
It will not start up from the Leopard installer disk.
It will not start up from the Disk Warrior startup disk.
I did run Disk warrior on the hard drive via Target Disk Mode and another computer.
Everything is disconnected from the computer except monitor, keyboard and mouse.
I have swapped the RAM with another identical computer that runs fine.
Battery has been tested and is fine.
Does anybody have an idea of where to look?
thanks
Ken

I seem to have similar issues. 3 out of about 40 times have I been able to get a second chime out of my pram reset...then I hols and get about 3 more. Each time...OS starts up and works just fine...until I sleep/shut down the computer. My drive has 5 gigs left on it, i hear that may be the issue. How do we remove the graphics card and reset that????
oh and BTW...leaving the plastic door off and trying to reset PRAM worked 2 out of the 3 times for me. This is getting frustrating. Im gonna free up some drive space and see what happens. Let me know if/how the graphics card trick works. It's fairly ridiculous that so many of us have these same issues.

my daughters mac book will not start up from power button

Hello trayce64,
Thank you for the question. I would be concerned too if my MacBook was not starting up. If you have not yet tried the following steps, I recommend steps 1-6 below to isolate and troubleshoot this issue:
Resolution
If your computer won't turn on, try each of these steps:
Verify you have a good connection from your Mac to the wall outlet by confirming the power cord and adapter if present are securely connected and plugged in. To check if the wall outlet is working, plug in a lamp or other electrical device.
If the wall outlet is working and you continue to have no power try another power cord or adapter if available. If it works you may need a replacement cord or adapter.
Note: See Apple Portables: Troubleshooting MagSafe adapters for further troubleshooting with MagSafe adapters.
Disconnect all accessories that are plugged in to the computer, such as a printer, hub, or other mobile device.
If your Mac supports user-installable memory, solid state drive, or hard drive, and you recently installed any of these, make sure they are installed correctly and are compatible with your computer. If possible, reinstall the original memory or drive into the computer to find out if the behavior persists afterwards.
