Leopard Install Disc Won't Mount on PowerMac G4

I'm having problems installing Leopard and am looking for advice. My internal DVD reader won't mount the installation disc - this has been a long-standing issue with my DVD drive: it can read some DVDs but not others. This is only the second time I've had trouble reading an actual Apple-manufactured DVD, though. (The first time, it was iLife - I eventually got around the problem by using a third-party DVD drive to install iLife, and that worked fine.) This time, though, while trying to install Leopard from the external DVD drive, the installation failed halfway through. This happened twice in a row, and I had to go back to my original system discs that came with the computer and reinstall the original system (10.2) in order to get my computer working again.
Now, I have two questions that arise from this. One, is this DVD-reading problem on my internal drive something that can be fixed with a Firmware update or something? I've searched without success. Or does the drive have to be replaced completely?
Second, is the problem with trying to install from the external DVD drive likely to be an issue with the Leopard install disc being a dual layer disc (if it is - I have no idea), and maybe the reason it fails halfway through is because my external DVD drive is only able to read one layer of the DVD? Or am I completely barking up the wrong tree with this one? Is it just a bad idea to try and install from an external DVD drive, full stop?
Colour me baffled! Any advice gratefully received.

I do not know for sure, but as the Leopard install DVD has a capacity of over 7GB it may well be a dual-layer DVD.
Assuming your G4 PowerMac otherwise meets the minimum requirements for Leopard (867 MHz or faster, 512 MB memory, 9GB free space on hard drive, etc.) it is possible there is a flaw in the DVD. When you attempted to install did the installer successfully verify the DVD? You could try using Disk Utility to verify the DVD.
You might consider a new internal DVD drive. I had to replace the optical drive in my G5 when it failed. They are quite reasonably priced here: http://eshop.macsales.com/shop/optical-drives/superdrives/powermac/
Do you have an external FireWire hard drive? Did you attempt to install Leopard on that drive?

FCS 2.0.1 Install Disc won't mount

Trying to install on MBP 15 inch/Snow Leopard - The disc has been cleaned no scratches (only used once for previous install). Have tried to mount the disc on other MBP 15 inch and it won't mount there either. This is an upgrade from FCP6.
Is there a way I can get an exchange from Apple? I don't believe there are any other options at this point - and I seriously need to transfer the application to the new machine (other machine has been dropped and screen is failing/middle of 2 jobs/yada yada yada).
Thanks in advance for your help ...

Can Disk Utility see the disc?
If not, try with an external DVD recorder.
If so, select the disc in the sidebar.
Go to File > New > Image From Device. It should have already selected the installer disc.
When you get to the Save Dialog, change the format to DVD/CD Master.
Don't change the name. Save where you want.
Double click the disk image to mount it and run the installer.

Leopard Install Disc won't restart into installer.

I have a G5 quad core and am trying to install Leopard from my family pack installation disc. My superdrive is malfunctioning and will not accept any discs (spins as though it's loading, clicks and tries again, only to spit the disc back out). I purchased an external DVDRW drive by USB quite a while ago because of this. I put the disc in, I can double click to install, it asks me to restart and on restarting it loads right back to asking me for my password. I have tried holding down "c" on restart and the Install Disc never shows up. I have tried holding down "option" on restart and only my hard drive shows up. I tried to load from another computer that I have assuming to share it's drive, but when holding "option" on restart it doesn't give me an option to pick a network.
I'm Lost, Please Advise! Thanks.

A PPC such as your G5 will not boot from a USB connection. However assuming that the other computer has a FireWire port, you can probably "borrow" its DVD drive to install Leopard, even if the other computer is an Intel. You will need an appropriate FireWire cable that can connect the two computers.
I would try the following:
Shut down the G5. Insert the Leopard DVD into the other computer, and restart the other computer while holding down the T key, booting the other computer into [FireWire Target Disk Mode|http://support.apple.com/kb/HT1661] . Connect it to the G5 and then start the G5 while holding down the Option key. This should boot the G5 into the startup manager, and hopefully you will see the Leopard OS X install DVD as one of the startup choices. Select that, and proceed with the Leopard installation. Be sure you pick the correct "Macintosh HD" (the G5's HD!) for the install.

OS X 10.5 Leopard install disk won't mount

I'm running OS X 10.4.11 on an iMac G4 and want to upgrade to OS X 10.5. I bought a retail 10.5.1 installation DVD set but I can't get the disks to mount on my iMac G4. I've tried loading it in with OS 10.4 running and I've tried starting up from the 10.5 disk holding down the C key. I've also tried starting up holding down the option key. Nothing seems to work. The disk does not show up in disk utility. The disks are apparently ok because I can mount them on my intel iMac as a test.
Any help would be greatly appreciated.
Thank you

Some Macs are not able to boot from USB drives.
These options come to mind:
1 - Make a bootable USB stick - very slow and painful - several tutorials on the web
2 - Make a reduced (single layer DVD) - not too difficult - I have done it several times - let me know if you decide to do this - I can give you a list of items to remove.
3 - Partition your G4 hard drive, boot into installer on one volume and install onto the other volume - very fast and easy - useful in the future - if G4 has important data this will need backing up to another disk first as partitioning normally erases the whole disk.
For 3:
1 - If necessary backup all data, and perhaps whole disk, to another disk with eg Carbon Copy Cloner
2 - Use Tiger install CD/DVD to partition G4 disk - can be equal volumes or perhaps make one about 10 GB for installer.
3 - Install Tiger onto one volume - the larger one if they are different
4 - Boot into Tiger volume
5 - Use Carbon Copy Cloner to clone Leopard installer onto the other volume
6 - Boot into installer and use it to replace Tiger with Leopard
In future you can use the installer volume in the same way that you would use an installer DVD for repair or reinstalls etc.
Good luck.

Macbook Leopard Install DVD won't mount

I want to perform an erase and install of OS X 10.5 on my late-2008 Aluminum Macbook. When I insert the "Mac OS X Install DVD" which came with my MacBook, it will not mount. The Macbook sounds like it's spinning up the DVD, but then ejects the install DVD within 20 or 30 seconds.
Any suggestions? To anticipate questions & suggestions:
1. Yes, this is the DVD which came with this MacBook.
2. Yes, this MacBook can read other DVDs.
3. No, I don't have an external firewire hard drive I can copy this disk to.
Can I remote install this DVD from a Mac Mini running OS X 10.4?
Any other ideas?

Well, the instructions are given for use with the MBA, but it should work on any recent laptop Mac that has a wireless network.
There can be any number of reasons. The optical drive is out of alignment, there's a motherboard problem, the drive's mechanical side is not working correctly, you have a corrupted OS X installation system, bad or marginal RAM, etc.
If you have another Mac with a dual-layer DVD drive and a blank dual-layer DVD-R disc, then you might try duplicating the disc on the other computer, then try booting from the duplicate. See:
Duplicate a CD or DVD
1. Insert the DVD/CD;
2. Open Disk Utility, and select the DVD/CD from the left side list (select the DVD/CD icon on top);
3. from the DU File menu select New | Disk Image from Disk 1;
4. Choose to format the disk image as DVD/CD Master, name the disk image and click Save;
5. When the .cdr file is finished select it with mouse and press COMMAND-I to open the Get Info and check the box to lock the file;
6. Choose the .cdr file from the left side list, click Burn, and insert a new, blank DVD or CD.

Need to reset password in Panther 10.3.9. Retail install disc won't mount.

I'm at the end of my wits here. I actually need access to Carbon Copy Cloner, but everytime I put in the password and click "clone" it says I entered in incorrectly.
I did this a while back with my Tiger, G4 PB. I believe the Tiger install disk will allow me to reset password (it won't with Panther).
Everytime I boot from the CD, I end up stuck in the blue screen.

TheRobotsCubicle, welcome, either you need to fill out your machines profile here or give us a little more info on your computer and any add-ons. In the mean time try resetting the PRAM.

TS1545 I have downloaded 10.5.8 combo several times and cannot get it to install because the disc won't mount or the installation gets hung up after restart. My current os is 10.5.1, and I am trying to upgrade to snow leopard. This is on a dual core macbo

I have downloaded 10.5.8 combo several times and cannot get it to install because the disc won't mount or the installation gets hung up after restart. My current os is 10.5.1, and I am trying to upgrade to snow leopard. This is on a dual core macbook pro.

You don't need to update to Leopard 10.5.8 unless you want to keep Leopard. Upgrading to Snow Leopard requires that your purchase the retail install disk.
The following covers Leopard:
Some general advice on updating:
It is worth noting that it is an extreme rarity for updates to cause upsets to your system, as they have all been extensively beta-tested, but they may well reveal pre-existing ones, particularly those of which you may have been unaware. If you are actually aware of any glitches, make sure they are fixed before proceeding further.
So before you do anything else:
If you can, make a full backup first to an external hard disk. Ideally you should always have a bootable clone of your system that enables you to revert to the previous pre-update state.
Turn off sleep mode for both screen and hard disk.
Disconnect all peripherals except your keyboard and mouse.
1. Repair Permissions (in Disk Utility)
2. Verify the state of your hard disk using Disk Utility. If any faults are reported, restart from your install disk (holding down the C key), go to Disk Utility, and repair your startup disk. Restart again to get back to your startup disk.
At least you can now be reasonably certain that your system does not contain any obvious faults that might cause an update/upgrade to fail.
3. Download the correct version of the COMBO update from the Apple download site.
The Combo updater of Leopard 10.5.8 can be found here:
http://support.apple.com/downloads/Mac_OS_X_10_5_8_Combo_Update
If you prefer to download updates via Software Update in the Apple menu (which would ensure that the correct version for your Mac was being downloaded), it is not recommended to allow SU to install major (or even minor) updates automatically. Set Software Update to just download the updater without immediately installing it. There is always the possibility that the combined download and install (which can be a lengthy process) might be interrupted by a power outage or your cat walking across the keyboard, and an interrupted install will almost certainly cause havoc. Once it is downloaded, you can install at a time that suits you. You should make a backup copy of the updater on a CD in case you ever need a reinstall.
Full details about the 10.5.8 update here: http://support.apple.com/kb/HT3606
More information on using Software Updater here:
http://support.apple.com/kb/TA24901?viewlocale=en_US
Using the Combo updater ensures that all system files changed since the original 10.5.0 are included, and any that may have been missed out or subsequently damaged will be repaired. The Delta updater, although a temptingly smaller download, only takes you from the previous version to the new one, i.e. for example from 10.5.7 to 10.5.8. Software Update will generally download the Delta updater only. The preferable Combo updater needs to be downloaded from Apple's download site.
Now proceed as follows:
4. Close all applications and turn off energy saving and screensaver.
5. Unplug all peripherals except your keyboard and mouse.
6. Install the update/upgrade. Do not under any circumstances interrupt this procedure. Do not do anything else on your computer while it is installing. Be patient.
7. When it ask for a restart to complete the installation, click restart. This can take longer than normal, there are probably thousands of files to overwrite and place in the correct location. Do nothing while this is going on.
8. Once your Mac is awake, repair permissions again, and you should be good to go!
If your Mac seems slightly sluggish or ‘different’, perform a second restart. It can’t hurt and is sometimes efficacious! In fact a second restart can be recommended.
9. Open a few of your most used applications and check that all is OK. In this connection please remember that not all manufacturers of third party applications and plug-ins, add-ons, haxies etc, will have had time to do any necessary rewrites to their software to make them compliant with the latest version of your operating system. Give them a week or two while you regularly check their websites for updates.
N.B. Do not attempt to install two different updates at the same time as each may have different routines and requirements. Follow the above recommendations for each update in turn.
Lastly, Apple's own article on the subject of Software Update may also be useful reading:
http://docs.info.apple.com/article.html?artnum=106695
[b]If you are updating Safari (or just have):[/b]
Input Managers from third parties can do as much harm as good. They use a security loophole to reach right into your applications' code and change that code as the application starts up. If you have installed an OS update and Safari is crashing, the very [i]first[/i] thing to do is clear out your InputManagers folders (both in your own Library and in the top-level /Library), log out and log back in, and try again.
So, disable all third party add-ons before updating Safari, as they may not have been updated yet for the new version. Add them back one by one. If something goes awry, remove it again and check on the software manufacturer's website for news of an update to match your version of Safari.
Most errors reported here after an update are due to an unrepaired or undetected inherent fault in the system, and/or a third party add-on.
Additional tips on software installation here:
http://docs.info.apple.com/article.html?artnum=106692
To reiterate, Input Managers reach right into an application and alter its code. This puts the behavior of the affected application outside the control and responsibility of its developers: a recipe for problems. That's not to say that issues absolutely will ensue as a result of Input Managers, but you, as a user, must decide. If the functionality of a specific Input Manager or set thereof is really important to you, you may well choose to assume the associated risk.
Again, the advice is to remove all Input Managers from the following directories:
/Library/InputManagers
~/Library/InputManagers
especially prior to system updates (they can always be added back one-by-one later).

Install disc won't re-install Leopard on my Macbook

So, I recently upgraded my Hard Drive in my Macbook. After I upgraded, I thought it would be cool to have Windows XP on my Mac also. So I partition 20 gb of my Hard Drive off for XP. I ran boot camp to install XP and I kept getting an error. This left me with an empty partition of 20 gb on my Hard Drive. I read many posts on here and I decided that the best thing to do was to re-install Leopard completely and start over, fresh and clean. Well, I put my Leopard install disc into my dvd drive, and when the install starts up, I get an error message that says, "Mac OS X can not be installed on this drive." Also, the install disc will not eject, even before the install starts. My hard drive is completely blank right now, and I have no idea why my install disc won't work. What should I do?

Open Disk Utility again (from the installer DVD), click on the drive's name as described in the previous post, & click the blue "i" button to get the disk's info. Copy that to a reply in this thread so we can see it. Or just note the "Partition Map Scheme" info, which should say "GUID Partition Table."
If not, you did not succeed in repartitioning it, perhaps because you did not click the "Apply" button or something.
If so, make sure you are using the installer disk that came with the MacBook & not some other model-specific installer disk.
BTW, you can never eject the DVD if you have started up the MacBook from it, so that much is normal behavior. To eject the DVD, you must restart from some other boot volume.

External disc won't mount in Leopard, but will in Snow Leopard

I have a 5-yr-old G5 networked to a new iMac. I have had a 1-TB external HD attached via Firewire 400 to the G5 for about a year. Yesterday it didn't show up on the G5 desktop. I went to this forum, searched under "disc won't mount", got some ideas, ran DiskWarrior and Disk Utility...but nothing worked. They all said the disc was fine, directories rebuilt, etc., but it wouldn't mount. This AM it occurred to me that I had the correct cable, so I tried plugging it into the iMac instead. It worked. The data is safe, the disc shows up, everything seems to be OK, but it won't mount to the G5. Why would that happen, and how can I mount it to the G5? And how likely is the disc to remain accessible?

May I hop onto your thread as I have a similar problem.
I have a 5 year old G5 PMac with 10.5 onto which I have daisy chained two UltraMax 1TB firewire 800 drives. For the last 5 years I have been able, even with out sharing enabled, to connect to the G5 from a G4 Graphite with 10.4, a G4 Powerbook with 10.5 and now a MbP with 10.6.
After completing the login dialogue in the past from any other mac it would give me a list of the G5, it's Hard disk, user directories and the two Firewire Drives. On selecting them the drive would mount onto the desktop as a network drive. This went well until monday when it became temperamental in the morning and after a few restarts and one successful mount it has not shown up since. If I come to the G5 via the Go > Connect to Server I get a dialogue "Could Not connect to the server because the name or password are incorrect". If I try to connect via the network icon in the side window of the finder window I get a network dialogue log in, I get a list of folders and drives but then when selecting the FH drive get an error message which relates to the alias to the G5 Server requiring deleting or fixing.
Originally it just connected without any messing but now unless i make the firewire drive a shared drive the process on the other macs cannot see the firewire drive. NOTE - After having made the internal boot HD of the G5 shared, I can now see and mount this drive from the other macs but not the external drive.
This is causing me to pull my hair out, I have run disk utility, powered down unconnected and reconnected everything .The HD's appear to be working ok from the G5.
I urgently need to connect the FW drive to my G4 to do some work but it also needs to be connected to the G5, has anyone got a clue why I cant get G4 (or any other mac) to mount G5's external FW drive

How can I get past a Snow Leopard install disc hang-up?

Trying to upgrade 2009 Mac Mini to Snow Leopard from 5.6.8. Install disc won't allow install to Mac HD because it insists Time Machine is using Mac HD for backups, but it isn't. Time Machine is using a partitioned 1T external drive. How can I get the install disc to acknowledge and upgrade on the internal HD?

Allan, There was exactly that file on the internal HD - and on each of the three partitions of the external drive. I dragged all such files to the Trash, which seem to eliminate much of the file(s), but the Trash won't empty completely because of a message that "BootX" is locked, as is "boot.efi" - though I'm instructed to hold Option and Empty Trash (which won't hightlight; actually a "continue" button is the only choice in a dialog box). So now I'm not sure any of these "locks" are clearing; I want to re-start the computer before trying to install Snow Leopard again, and I can't have this hung up in the Trash in any case. Anything more you could suggest?
Thanks so much for your response and help.

SONY DVD RW DW-U10A Not Recognizing Leopard Install Disc

Welcome to the Apple boards:
The drive may need a firmware update.
It's also possible that the drive is no longer working properly.
Does the drive eject only the Leopard DVD or any other movie DVD for example?
What about CDs?
You might also clean the lens on the optical drive. RadioShack sells several CD/DVD lens cleaners.
Also, check in the system profiler under disk burning for any possible information about reading DVDs.
Remember that the Leopard DVD is a dual-layer DVD. Your drive should be able to read it, but the DL reading part is not the same as the normal reading part. I think it uses a different laser at the minimum.

Pagemaker is ancient, obsolete and unsupported. It was discontinued over 10 years ago. (Though why it is still sold is a mystery.)
If you want to run PageMaker, your best bet is to use a Win2K or WinXP PC.
Otherwise move to Indesign or look at Serif's PagePlus or Scribus.

I used utilities to source my 10.6 snow leopard install disc to my main hardrive, and now when I turn on my computer the apple with the spinning wheel stays on the screen and stuck like that. How do I fix it Help please. I already tried all the commands

I used utilities to source my 10.6 snow leopard install disc to my main hardrive, and now when I turn on my computer the apple with the spinning wheel stays on the screen and stuck like that. How do I fix it Help please. I already tried all the commands such as Command R, Holding down the Option key, C and holding down shift at the start up but nothing happens.
initialy All I was trying to do was downgrade 10.7 to 10.6 .

You have to consider the possibility the hard drive may be dying. If your data isn't backed up, try one of the tools below:
https://discussions.apple.com/docs/DOC-1689
Once you are sure your data is backed up, we can examine other possibilities. In the meantime call AppleCare for your original installation DVDs. You may need them.

How do I reinstall my operating system after hard drive upgrade on MacBook pro? I have Snow Leopard install disc

How do I reinstall my operating system (Snow Leopard) after a hard drive upgrade. I did a Time Machine backup before the new hard drive was installed. I put in the Snow Leopard install disc and don't get the icon I'm supposed to double click to install Snow Leopard and then the backup.
HELP PLEASE!!

Is the new HHD in the MBP?
Is the new HDD formatted Mac OS Extended (Journaled)?
Where is the old HDD? In an enclosure? What is on the old HDD, your user data? Is the Snow Leopard System on it?
Do you have a separate Time Machine Disk with your user data?
Answers to these questions should give an exact status of your situation so that one can proceed in the right direction.
Ciao.
