Leopard Install Hangs because G4-MDD goes to sleep

Computer in question: Power Mac G4, MDD, Dual 867MHz.
Had Leopard running fine, though I remember having a similar issue when doing the original install. The main hard drive crashed (no question - terrible grinding noise). Replaced the hard drive, started Leopard install, selected a recovery from Time Capsule. Started off great, everything seemed fine. When I came back later, I noticed the screen was off (power management) - moved the mouse and it came alive, but I got the 'system busy candy spinner' (not sure what else to call it) and the progress bar had stopped moving.
Tried several more times, and I noticed each time the process seemed to be working fine until I forgot to move the mouse every so often, then once it slept there was no coming back.
I tried installing a bare minimum Leopard install (much faster than a Time Machine recovery) and set the Energy options to "never / never", but the Leopard install DVD seems to have its own settings, and there's no apparent way to change the energy settings after booting the install DVD (no Control Panel access).
Any ideas other than sitting at the workstation for hours, moving the mouse every 10 minutes?
As I said I remember having an issue during the regular Leopard install like this as well - but that was much shorter and easier to sit there moving the mouse while the install completed. The Leopard recovery from Time Capsule is estimating anywhere between 2-8 hours depending on when I look...

Well, I might've found a fix - booted the install DVD and after selecting a language I went to the Utilities menu, picked Terminal. From a terminal session I typed:
pmset -g
Which shows the current power management settings. I could see it was set to sleep the display, disk, and system after 10 minutes. Then I typed:
pmset -a sleep 0 disksleep 0 displaysleep 0 force
Which told it to change these three to NEVER sleep, and "force" makes the command activate the settings even if it can't write the settings to disk (which it can't on a DVD obviously!)
pmset -g
Then told me those three were set to 0 (zero) and I exited the terminal process and continued on with the Time Machine full system restore (also in the Utilities menu) and I think this will do it... I'll update this thread and let you know!

Leopard install hangs up

Around 3pm today, I inserted the Leopard OS X 10.5 disc and double-clicked "Install Mac OS X". In the following window I clicked "Restart" and now my computer has "hung up" with the colored spinning wheel and has not restarted. It's now been seven hours.
One possible issue is that the computer goes to sleep during this process. Will that stop the restart from proceeding? Is there a way for me to change the Energy Saver settings now that it has reached this point? If I simply shut down and restart my computer is there any danger that I might lose information or corrupt my hard drive (80GB internal). Also, I have a 500GB external FireWire drive connected to the computer. Should I remove the FireWire connection before proceeding with the Leopard installation?

If you never got to the DVD self-check stage, which occurs first, then nothing should have changed and your system should still be Tiger.
The system should have immediately proceeded with the 10 minute DVD self-check.
See if you can eject the DVD with the keyboard. If not turn it off and restart it and hold down the left mouse button or the touchpad bar.
Check the DVD very carefully for scratches or that thin oily film found on some disks. If it has that file, clean it with a damp soft cloth, wiping radially center out. Do not wipe in a circular motion!
You should then be able to boot into the safe mode by holding down the shift key. After the system boots, restart it back to normal. Since you got to the first part of the install already, simply reinsert the DVD and shut off the computer.
Restart holding down the "C" key and you should boot into the DVD from which you can continue the install.
Be sure that you have done the normal preparations first: use the Tiger DU to check/repair the HD and file permissions. Do this before rebooting the system if you have not already done so. These two operations are very important for a smooth install.

Macbook Leopard Install Hanging

Help,
I have bought a retail version of Leopard 10.5.1 but every time I try and install it it just hangs there for ever doing nothing. Am I doing something wrong? I have trawled the groups and cannot find anyone else who has the same problem.
I have erased the HD repartitioned it and i still get the same result. Here is the log file showing the point that it gets to everytime before it just hangs.
Any advice greatly appreciated.
Thanks

I did the erase zero out data using DU, and I still get stuck at "extracting", It has been mentioned to me that the optical drive may be getting to hot, but the same thing happens even if i do it from an image off the hdd.
I have used 3 different leopard retail disks so i cannot believe that all 3 are bad dvds.
Maybe it is a problem with the optical drive, maybe it is something to do with the hdd / firmware or systems management. Who knows. It seems that apple care have no idea either.
I can install windows XP on it for heavans sake!! It's ridiculous that an apple os product will not install on native apple hardware.
Like I said earlier I will never buy an Apple computer again based on this experience. Windows Vista people moan about that OS but as far as I can see its streets ahead. To think I was almost an apple convert

Leopard install hangs at DVD reboot

I cannot upgrade from OSX Tiger to OSX Leopard on my G4 iMac. I insert the DVD and follow the prompts to do the installation, however when my iMac tries to boot from the installation DVD it just hangs at the grey screen showing the apple logo and sits there indefinitely ( in desperation I have left for over 3 hours!)
My iMac is a 17 inch 1.25 GHz G4 so is fully Leopard compatible. I have used the same (Family pack) media to upgrade my MacBook with no problems. I have tried removing all peripheral devices, including oem memory and still no joy.I have repaired all disk and permissions issues using the Tiger DVD and all firmware is fully up to date.
I am totally at a loss to as to what to do next. Any help would be gratefully received.
Happy New Year

go to apple support and type in" imac and leopard." There's some software or firmware updates you probably need to do.

Can't finish snow leopard install, hangs at apple logo?

Everytime I run my install it will get to 45 minutes and then be stuck at the apple logo with the spinning wheel. When I try to boot from the disk also this happens. I'm pretty sure my drive is working as it can read other discs. This is also the retail disc with the snow leopard, 10.6. Disc utility tells me everything is verified, and I have also run applejack. I'm currently at 10.5.8 on a late 2006 macbook a1181. Intel Core 2 Duo with 2 gb. I know my laptop can run this but I keep getting stuck at this screen.

Thanks for your help!
I will try my Tiger Install Disk (4x CDs) to see if they work. I am able to play / burn CDs and play DVDs fine so this problem sounds fishy. I will try to clean the lens as suggested. If its of any relevance, i cant boot into by Carbon Copy Clone on my external HD either! (its formatted in APM and everything!) over FireWire. Bhaaa...
Oh well, at best i will re-install Tiger and head off to my local Apple Store and see whats up...

Snow Leopard install hangs

I tried an upgrade on my iMac6.1 from Leopard OSX 10.5.8 to Snow Leopard 10.6.3 (DVD) and the installation hung. When I inserted the DVD and began the upgrade procedure, the installation appeared to progress normally. The Install Mac OS X screen came us and the progress bar continued for about 10 mins. However, the installation appeared to get stuck after the Install window had gone away and the background and the wait cursor remained on the screen - it got 'stuck' here for about 45 mins and I aborted the install with a reboot. I noticed there was a "Mac OS X Install Data" folder created on the Mac HD, so obviously the installation progressed a certain way. The reboot put me back to by 10.5.8 system without any noticable problems.
I have not been able to find a problem that was described quite like this one so some help would be appreciated. Also, when the system rebooted with the SL DVD in the drive, it of course wanted to proceed with the installation - I was a little leary as I do not want to loose my apps, configuration and data (data is backed-up).
Help?

Rebooting the computer with the SL disc or starting the install by just popping the disc in and clicking install results in the same thing. There are lots of possible explanations for what you experienced. It is possible that the computer gods deemed your day for a crash had arrived. It might be the installation disc is a little dirty. Your hard drive may be barely empty enough for the installation. It may not have actually stalled at all! During the beta period last summer Apple engineers tinkered with the progress bar and timer quite a bit but it still is only (very) roughly accurate.
If you can do so, I strongly recommend you back up your computer and then try installing the OS again.

MacBook Pro goes to sleep when copying files from attached drives

I have noticed that since installing Yosemite my MacBook Pro goes to sleep when it is in the middle of copying a large number of files. When I wake it up the copying continues.
I have also noticed that when I am watching videos from my shared iTunes library on an Apple TV the video will stop after about 15 minutes and the connection to the library is lost because the MacBook Pro has gone to sleep. When woken up then access to the library is restored but I need to reselect the movie and then resume.
I have changed the power saving options to do not let drives sleep when idle and do not sleep laptop.
Anyone else have any experience of this or better still a fix.
Thanks in advance.

I have just found that if I turn off the display sleep in the power settings then the problem is resolved. It means though that the screen on my MacBook Pro is on all the time albeit with a screen saver.

I uninstalled the operating system to wipe it because I was going to sell it. I thought I had the right CD to re-install everything but I don't! Any ideas?

Since you said the computer had seen an upgrade in OS X, the last possible
version and most likely installed would have been from a Leopard 10.5 DVD
retail install disc; so if you have one of those, that would do the job...
IF image of the retail box does not appear below, the cover was all black w/
a black X, and a purple swirl behind it of a galaxy. The label would have a
number and the 10.5 system identifier. It would not be a gray label disc.
https://www.apple.com/support/leopard/
Of course to call Apple as recommended by Klaus is way to see about getting
the disc set for the model, and would be a fair part number to include with it
if available. Any installed OS X should (where applicable) have the DVD, too.
The Disc is the proof of license; and unless a 'family pack', one install per DVD.
There may be a generic white label 'replacement 10.5 DVD' from Apple support
as had been noted by a few ASC discussion participants, that was for any PPC
mac that could run or be upgraded to Leopard 10.5. A full install disc of the OS X.
This was available for a time, for a reasonable fee. Also, a more rare DVD version
I have, that is a full installer on bootable DVD, says 'drop in' 10.5. and did not
require an older OS X to be installed & running prior to using that to upgrade. Do
not plan on finding one of those, but I have the actual rare disc at my Mac, now.
{Also have an as-new retail boxed set, bought from a moving sale, cost me $10.}
In any event...
Good luck & happy computing!

PPC G5 system hangs after Leopard Install

Well I had been monitoring things with the new OSx for awhile before installing. I had upgraded my Macbook Pro (Intel first Gen model) and my newer Intel MacMini with no issues. So after using both of these machines for quite awhile, and with the release of 10.5.2, I decided to upgrade my PPC G5 from Tiger to Leopard.
Everything seemed to go fine. I installed all possible updates and have used several apps with no problems, such as Adobe PS and Dreamweaver, etc. But now I am starting to notice a serious problem.
Every time my system either goes into Screensaver mode or sleep, when I try and bring it back it is frozen. All I get is the beachball and the only thing to do is a hard shut down with the power button. My system never did anything like this under Tiger.
Has anyone experienced a system hang like this?

Do you have any external drives (especially Maxtor or Maxtor OneTouch Drives)?
I know on Tiger I had this same problem and it turned out that there was a problem between the Mac's Firewire drivers and Maxtor OneTouch drives. Maxtor had a patch that fixed the problem on Tiger, but I'm not sure if the patch is needed also for Leopard. Not sure if Maxtor drive support is continuing since Seagate bought them.
I'm currently having a problem on Leopard with hangs (not specifically the same as yours). I'm wondering if it is again a problem with compatibility between Leopard and the Maxtor drives.

Family Pack Leopard install fails G4 Dual 1.2Ghz

All, I purchased the Leopard family pack and have successfully installed it on an Intel Macbook Pro and a G5 2.3Ghz DP machine - flawless, no problems during installation or after.
However, any attempt to install on a G4 Dual 1.2Ghz + 2Gb of RAM + just bought a Seagate 500Gb Barracuda internal drive (well within the designated technical requirements), I've tried the following.
1. Booting the G4 off the Leopard install DVD, I get the following error: Failed Install message = "The Installer could not validate the contents of the Essentials Package...".
I can never get beyond this point. After receiving this error, the internal disk isn't even recognized on the bus - I have to pull the disk out, put it in an external case to reformat it. I've even tried a low level format and also had Seagate replace the disk thinking it was defective.
2. I then thought it may be an issue with putting the Seagate disk in cable select mode versus master / slave configuration. The Seagate is the only hard drive in the machine. I have tried both cable select and master/slave configuration - both freeze after install, etc. without fail.
3. Tried installing Leopard on the G4 by connecting it to the G5 in target disk mode. It installed, but routinely just freezes (NEVER had this issue with Tiger on this machine).
I do see lots of people posting issues with the "The Installer could not validate the contents of the Essentials Package..." error.
For the record, after successful Leopard install using technique #1 and #3 - I am also unable to run the Migration assistant - it fails every time with a kernel panic. I'm not having any trouble with the Leopard install media on any of the other 2 machines, nor did I have issues running the migration assistant.
Any ideas are appreciated. thx,

themdg - you said you put back your 2-512 original RAM cards and tried to install Leopard and the install failed. But my original, factory-installed RAM was third-party RAM which prevented me from installing Leopard, giving the “essentials” error. Only when I purchased RAM from Apple, and used only that RAM to install, could I get it to work correctly.
Check your original RAM. If it is not the Apple brand, it may not work because of that, even if it was the factory-installed RAM.
After I installed Leopard with only the Apple RAM, I added back the third-party RAM and I’ve been running Leopard flawlessly since.
It seems the installation software, which meticulously checks the installer disk for flaws, should also check the RAM to see if the installation will be successful (i.e., check to see if it is going to produce the “essentials” error) and also check to see if you have enough valid RAM to install, before it begins installation, and to let the user know there will be a problem unless the RAM is changed to valid cards.
I “assumed” I had enough valid RAM when I first tried to install Leopard because I had a G5, but it had only 256 MB of non-Apple brand RAM (minimum of 512 is required). A direct check of that by the installer and letting me know it was a problem would have saved me a lot of trouble checking lots of other potential problems, like a bad installer disk, a third-party drive, etc., before I figured out it was insufficient and incompatible RAM for the installation.
I read the minimal requirements for installation of Leopard and probably someone will say I should have checked all those before I tried the installation, but I didn’t, as I’m sure many others have not, because we “assume” Apple had tested it and would prevent us from making any mistake like this.
Previously Apple made their software and hardware to “just work” by providing error messages before we made an error and we have come to rely on that. But they overlooked this problem on this update. It’s the first time I’ve had a problem with an update from Apple.
I’m still a loyal Apple user, but I’ll check requirements a little closer with future updates.

Itunes and new Leopard install

Ok, I really wish I could go back a few days and not spend the time or money on Leopard until the powers that be get it running LOL.
Anyway, I started my Leopard install 4 days ago and just got it going (every problem listed).
I just tried to open my Itunes and get the error-
"The file "iTunes Library" cannot be read because it was created by a newer version of iTunes"
Any ideas or suggestions would be appreciated. I'm getting beyond frustrated with this thing.

Start by checking if you can run Snow Leopard:
Requirements for OS X 10.6 'Snow Leopard'
http://support.apple.com/kb/SP575
Whilst Apple have withdrawn Snow Leopard from their stores, you can still get it from Apple by calling 1-800-MY-APPLE (if you are in the USA) and they will supply the SL DVD for $20 for a single user, or $30 for a family pack that covers up to 5 Macs. You can also purchase the code to use to download Lion from the same number (Lion requires an Intel-based Mac with a Core 2 Duo, i3, i5, i7 or Xeon processor and 2GB of RAM, running the latest version of Snow Leopard), or you can purchase Mountain Lion from the App Store - if you can run that:
http://www.apple.com/osx/specs/
If you are outside the US call your national Apple Helpline:
http://support.apple.com/kb/HE57
If you're in the UK, use this number: 0871 508 4400
When you have installed it, run Software Update to download and install the latest updates for Snow Leopard.
To use iCloud you have to upgrade all the way to Mountain Lion:

I want to buy a new Macbook pro 15", but I don't like Lion, I want Leopard installed, is there any issues with drivers or any other I should be aware of?

I want to buy a new Macbook pro 15", but I don't like Lion, I want Leopard installed, is there any issues with drivers or any other I should be aware of?

Hello, I've tried Lion from the day they released to last week I got my computer formated and with leopard again, on my iMac 24" from early 2009 2.9 Ghz core 2 duo, and I have installed 8 Gb of memory, and i have some complains about it, there are some cosmetic issues but mostly I'm concerned about issues bellow the hood, as I'm a stock trader and I depend completly from my computer's performance, let me explain:
Superficial issues:
1. They took off "spaces" and I liked it.
2. I dont use the magic mouse, I need a more accurate mouse for my charts, and it seems they built the entire OS assuming you would use the magic mouse for gestures, scroll, etc to try to mimic in some way the Ipad and Iphone functions, but what if you arent using it like me?
3. I never used that little rocket icon that makes all your apps appear and that could be one of the "improvements on Lion", at first sight it looks nice and slick, but if you try to use it and make it part of your daily use, you would find it is useless, it is a pain to try to arrange it the way you like it, so I rather use the spotlight to search for my apps, its faster.
Now the MOST important, 'performance':
1. It completly suffocate my computers hardware Leopard much more lighter, beggining from the start up that taked almost 1/3 or twice the time, and I think Lion has some bugs bellow the hood, i was doing my normal stuff, some apps running and everything, and suddenly I started to feel the computer a little slow, safari taking forever to open the pages for example, and I opened the activity monitor to see what was going on, and it was there, I was using 4 or 5 gb from my memory, and CPU making insane peaks, and Im using 2.46 gb as im writing it doing exactly the same stuff, (but Im happily using Leopard now), and it wasnt once, as i told before, I used lion since the day they released it and happened several times until it drove me nutts. But leopard not problem in that regard at all, Never.
hope this helps, and hope some apple guys read that because lion resulted in a big disappointment for me.

Is the Snow Leopard Install DVD supposed to auto-eject during installation?

I just recently purchased Snow Leopard and everything seemed to be going well. The installer popped up after I put it into my External DVD Drive and the installation was going smoothly but soon my MBP would restart and the installation would continue. The problem is that at around 35% completion, or in my case 32 minutes left, the disc would come out of the drive and any attempts to put it back in would result in the DVD drive promptly spitting the disc back out.
I don't think it's the MBP that is at fault since I would have received an error message or something of the like. My only guess is that either the Installation DVD is faulty or the External DVD Drive is causing the issue. I'm leaning towards the DVD Drive especially since it suddenly stopped reading the disc entirely while I'm typing this.
I'm using an AmazonBasics USB 2.0 8x DVD Writer External Optical Drive which should be fully compatible with Macs.
Any and all help is greatly appreciated, thanks in advance

Yes I checked it on several occasions for dirt, scratches, and the like and everything seems in order.
I'm able to input the setup information after the MBP reboots, the disc ejects after that point while installing.
The reason I'm using an external DVD reader is because the one my MBP doesn't work anymore for whatever reason and the warranty is expired.
Also disregard the comment I made about the external DVD reader not reading anything at all anymore.

Leopard install has locked me out!

This, I think, is different:
1) I did an Archive and Install and rebooted successfully into my Admin account.
2) As I began to work, I noticed that things started acting strangely. I was asked to type the Admin password for a simple task and it did not recognize it when I typed it. It gave me three tries and quit.
3) I rebooted and found that my Admin account had completely disappeared from the Login window. Only "standard" accounts were listed.
4) I logged into one of the standard accounts and found that the files from my Admin user account were still in the computer but inaccessible.
5) I tried the shell commands that Apple suggests but found that I could get no further than the "ls /Users" command and was informed that the subcommand "ls" (List) was unrecognized. HELLO?
So, I am going back to Tiger and staying there until Apple provides a way for the rest of us...

That's a curious situation, and so I have to assume you have issue with the Mail set-up in Snow Leopard after upgrading, because those settings no longer work now...? When you upgraded to Snow Leopard 10.6.8, did you choose to install Rosetta?
There are several support articles for all of the services Google
provides, from their main page... https://support.google.com/
For gmail in an email application, the setup is not too different now than it was a few year ago; however subject to change however often or whatever reason they want. +Their end user agreement spells it out.

Mine is set up to use Notifier, with a second browser most often used exclusively for gmail. However notifier is sadly 'going by way of the dinosaur' by the end of this month, according to progess reports from Google.
You may have to consider a different browser, and find the last applicable Adobe Flash player plugin for OS X 10.6.8. Safari is among five browsers in my Macs, however due to some being powerPC models, there are fewer great ones left and a few get upgrades. TenFourFox, Seamonkey-PPC, and iCab seem to be OK. However for my intel-based MacBook 13" (1.83GHz coreduo) with Leopard 10.5.8, there still is a working FireFox, a different version of Seamonkey that won't work on powerPC, & iCab that is universal. In Safari preferences, you can assign another browser as default to the system.
So you could still use Gmail by web browser and on
occasion save files to .zip archive, etc for offline.
The link to Gmail help should be of service;
or the support page for gmail for more info.
Good luck & happy computing!

Macbook Pro Leopard Install Issues - Will not start

Ok, so I bought a used Macbook Pro about 9 months ago. As soon as Leopard came out, I upgraded. It ran flawlessly until about 2 months ago. I kept getting random freezes, "ATSServer" errors, and a bunch of other random problems. I decided a fresh install was definitely the way to go.
So I backed all my stuff up and erased the drive (no zero out). Naturally, I installed Leopard on a OS X Extended Journal format. When the installation was finished and the computer restarted, it sat at the boot screen (the grey Apple logo with the spinning thing underneath it). Instead of booting, it just restarted and did the same thing again. It continued to do this and was clearly not going to boot into Leopard.
I tried installing again under the same format (OS X Extended Journaled). It did the same thing.
So I tried to install Leopard on a OS X Extended Journaled Case-Sensitive partition. It installed, and what do you know? The computer booted up fine. I updated everything with System Update and everything worked flawlessly. But then I tried to install Adobe Creative Suite and realized that it (along with other programs I need for work) CANNOT be installed on a case-sensitive drive...
So I erased again and tried installing on a Journaled drive (non-case sensitive)... it did the same thing as before. Kept restarting at the boot screen and continued this in a never ended cycle.. would not boot.
So I tried a Mac OS X Extended partition (non-journal and non-case sensitive). Leopard installed and this time it got past the boot screen. Went to a blue screen... then got hung up on a blank grey screen!
So basically:
OS X Extended Journaled: Restarts continually and will not get past boot screen.
OS X Extended Journaled Case-Sensitive: Works perfectly! But cannot install my most necessary Applications on this format.
OS X Extended: Gets past boot screen but stuck at a grey screen right before OS X actually boots.
As I said, I haven't tried installing on a zeroed out drive yet (it is zeroing out the drive right now), but do you think this could even have anything to do with the problems I'm having?
It just doesn't make any sense to me... Why the **** would it work on case sensitive, but nothing else? Hard drive problem? I thought it was the logic board, but it ran absolutely PERFECTLY when on a case sensitive format.
It is out of warranty, and even if I did have AppleCare, I NEED this computer for work. I CANNOT afford to send this in anywhere to get repaired.. and I really cannot see it being a hardware issue because like I said, it works PERFECTLY on a case sensitive partition, but will not boot on a Journaled or plain Extended partition.
I'm crossing my fingers that zeroing it out will work, but ***?
Thanks.

Did you get the disks the machine shipped with? If not, call 800-MY-APPLE and order replacement disks. Should be available for a nominal S&H charge. If so, boot with the one containing the Apple Hardware Test suite and run the extended tests. If it passes, download Rember and run its tests. If the machine passes, then you've probably ruled out any hardware issues. After the disk is zeroed out, try installing, only selecting the Mac OS Extended format and ensure that you choose the GUID partition map scheme. Journaling can be turned on and off with Disk Utility, so you don't need it for preparing the HD. BTW, the Erase & Install will automatically erase the HD (just deletes the directory) and turn on journaling.
