Premiers soucis à l'installation de Leopard
« le: octobre 27, 2007, 02:05:51 pm »
On voit sur différents TOPICS quelques problèmes rencontrés sur un certains nombres de machines. Voici ici les liens permettant de les consulter et de se faire une idée des configurations posant potentiellement probleme.

PROBLEME DE BOOT APRES INSTALLATION DE LEOPARD

Des centaines d'utilisateurs semblent reporter un probleme recurrent au premier reboot  apres installation de Mac OS X 10.5 (Leopard). Ce probleme semble etre un signe typique d'une installation réussi, mais un écran bleu persistent suite au redémarrage, necessite un shut down forcé. C'est sans surprise que l'on constate que le probleme rencontré par ces personnes semble avoir pour point commun le fait qu'ils aient tous fait un upgrade simple de leur système ("Upgrade Install") au lieu de faire un " Archive and Install" ou un " Erase and Install" ce qui est tout de meme fortement conseillé. Tous les "reports" indiquant ce type de probleme impliquent un "Upgrade Install" et nombreux sont ceux qui confirment qu'en faisant un "Archive and Install" ou un "Erase and Install" résoud le probleme de façon definitive.

Il semble que le premier reboot soit plus long que la normale -- près de 10 minutes voir beaucoup plus selon les configurations-- de nombreux utilisateurs ont patientés plus d'une heure: voila un indice permettant d'affirmer que quelque chose de plutot inquietant c'est passé <!-- s:cry: -->:cry:<!-- s:cry: -->

Voici quelques exemples de discussions sur différents forums:

    * "I'm upgrading my 20" iMac (Core Duo) at the moment and the installation 'completed', then the computer rebooted and it has been sitting on a plain blue screen for the past 30 minutes. Did a (straight) upgrade."
    * "15" MBP. Selected Upgrade. Ran through the install. Rebooted. Blue screen, black cursor, no activity I waited about 30 minutes before forcing the reboot. After bootup, same screen. I have Apple Care on the MBP so I called in."
    * "I received my copy of Leopard today and it is the same thing here with my PowerBook G4. It keeps getting stuck with the empty blue screen while booting. I tried rebooting a few times but it does not help at all. The vents are blowing full throttle so something is calculating, I guess. The mouse is moving but that is it. I am waiting for an hour now. [...] Maybe I should add that I did a straight update of my 10.4.10 and did not install the custom language support and some printers. Everything else remained standard."

MacFixIt reader K Stern adds:

    "Installing on a PB 1.67. 2megs of RAM. Running 10.4.10. Ran Disk Warrior before install. After doing a Upgrade Install it reboots. Gray screen for a few seconds then... Blue screen for 1 sec then... Blue Screen again then nothing. Waited over 1/2 hour. Noticed my fans running hard and lots of heat. What I've done so far: Shut down; Started up from Install disk; Run Disk Utility (no problems found); Tried to do it again with same negative results."

The obvious solution, which has already proven successful for most users experiencing this problem, is to simply boot again from your Leopard DVD by holding down the "C" key at startup and choose one of the Archive and Install or Erase and Install options. See this article for a description of the different install types.


Remove APE haxies (ShapeShifer, etc.)

Another potential cause for this issue that shouldn't be shocking if you've routinely paid attention to MacFixIt: the presence of APE modules. Before installing Leopard, remove APE modules via this uninstall process.

Again, some pertinent posts from Apple's Discussion boads:

    * "I managed to fix this issue with my machine. I was getting the BSoD (for shame, Apple, doing the same thing we used to be able to prod Windows users about) and suspected it to be APE. Rather than go through the insanity of uninstall/restore/archive and reinstall, etc, I decided to try to manually uninstall APE and continue booting. It worked"
    * "This solved it for me. I didn't have the (APE) prefpane loaded, but the others were there and removing them fixed it perfectly."

If you've already installed Leopard, can't boot, and need to remove the haxies, restart into single user mode by holding down the Command and S keys simultaneously during startup. Next, enter the following commands, pressing return after each (as compiled by Apple Discussions poster Chris Mcculoh).

    * rm -rf /Library/Preference Panes/Application Enhancer.prefpane
    * rm -rf /Library/Frameworks/Application Enhancer.framework
    * rm -rf /System/Library/SystemConfiguration/Application Enhancer.bundle
    * rm -rf /Library/Preferences/com.unsanity.ape.plist

Reboot normally and check for proper startup.

Interestingly enough, since these haxies are stored at a system level, they would have been eliminated (and, in turn, the startup problem eliminated) by using an "Archive and Install" or "Erase and Install" rather than "Upgrade Install."

Other fixes

There are also a few other fixes that might not necessitate the aforementioned, most culled from our tutorial "Startup fails (particularly after a system or security update); solving". However, we have to stress this point: if something has gone wrong during the installation of Mac OS X 10.5 that's causing the startup issue, these fixes may be only temporary and you might encounter other problems later. The only surefire way eliminate such problems is to perform a re-install and select something other than "Upgrade Install.":

Disconnect external devices Try removing any FireWire, USB or other external peripherals then re-attempting startup.

Take this Apple Discussions poster:

    "I had heaps of stuff connected to my laptop, I disconnected this before I restarted and this seemed to help."

Or this one (with a slightly different issue, in that Leopard wouldn't complete its installation):

    "I had the 10.5 install hang midway thru the 'Installing' screen on my trust old mac mini. It didn't move for about an hour so I hit the power off and disconnected all additional devices (2 x LaCie HDDS, EyeTV box, Apple TV) and changed from wireless mouse to wired. So far so good - the install has now proceeded way beyond where it was and tells me I have 15 mins left (the estimates that the install for time to complete are way out btw)."

Boot in Safe mode Try starting in Safe mode (hold the "Shift" key while you startup), then delete some cache and .plist files to make sure their corruption isn't at fault. Since many tools for doing this haven't been updated for Leopard, there is a manual process which involves dragging the following files to the trash:

    * com.apple.kernelcaches (a folder in /System/Library/Caches)
    * Extensions.kextcache (a file in /System/Library)
    * Extensions.mkext (a file in /System/Library/)
    * com.apple.ATS (a folder in /Library/Caches/)
    * com.apple.loginwindow.plist (a file in /Library/Preferences/)
    * Files that start with com.apple.LaunchServices (in /Library/Caches)


You will be prompted to enter your administrator password when dragging these files to the trash. You may need to restart after moving them to the trash.

Next, go to the Accounts pane of System Preferences and click the "Login Items" tab. Select all the login items and click Remove, then restart. Also, check the /Library/StartupItems and /System/Library/StartupItems folders and remove any third-party items.

Finally, look in the folder /System/Library/Extensions for any third-party kernel extensions (files that end in .kext). Remove the kernel extensions and check for persistence of the issue.

ATTENTION A VOS MOT DE PASSE DE SESSION

Première astuce pour règler ce problème:

Les mots de passe dépassant les 8 characteres peuvent vous empecher de vous logger sous Leopard.

Si vous utilisez un mot de passe ayant plus de 8 characteres sous Mac OS X 10.2.8 (Jaguar) ou plus récent, vous pouvez potentiellement rencontrer des  problemes pour vous logger sous Mac OS X 10.5 (Leopard). L'astuce pour corriger cela et trouver une solution à ce problème, est de se logger en mode single-user  puis ensuite de modifier le fichier se trouvant ici en utilisant le terminal:

/System/Library/LaunchDaemons/com.apple.DirectoryServices.plist

Voila à quoi ressemble une installation comment dire....prématurément foirée !!!!

Ici l'installation n'a pas pu se faire pour différentes raisons enoncées à l'écran. Pensez à Carbon Copy avant toute installation!!
