Bonjour,
Je n'arrive pas à installer la mise à jour 10.7.5 sur mon Mac Book Air.
La mise à jour se télécharge et, aprsè redémarrage, s'arrête en plein milieu de la mise à jour en affichant ce message d'erreur :
"La mise à jour « Mise à jour Mac OS X » n'a pu être enregistrée
La mise à jour n'a pas pu être vérifiée et peut avoir été endommagée au cours de son téléchargement. Elle sera téléchargée mais à nouveau recherchée au prochain lancement de Mise à jour de logiciels."
Sauf qu'au prochain lancement de Mise à jour Logiciels évidemment, elle ne se retélécharge pas.
Quelqu'un pourrait m'aider ?
Merci beaucoup !
Hello,
I do not succeed to install the update 10.7.5 on my Mac Book Air.
Download happens but after restaring the update is underbroken with the following error message :
The update 'Update Mac OS X could not be saved.
The update could not be checked and could have been damaged during the download. It will be downloaded again at the next launch of Software Update.
But obviously it does not happen.
Could someone help me?
Thanks a lot.

Answer 1

Read this whole message before doing anything.
Back up all data. Quit the App Store application if it’s running. Take the following steps until the problem is resolved.
Step 1
Triple-click the line below to select it:
/Library/Preferences/com.apple.SoftwareUpdate.plist
Right-click or control-click the highlighted line and select
Services ▹ Reveal
from the contextual menu. A Finder window should open with a file selected. Move the selected file to the Trash, leaving the window open. Relaunch the application and test. If there's no change, quit again and restore the file you moved from your backup, overwriting the one that may have been created in its place. Otherwise, recreate your settings in theSoftware Update preference pane.
Step 2
Hold down the option key and select
Go ▹ Library
from the Finder menu bar. Move the following items from the Library folder to the Trash (some may not exist):
Caches/com.apple.SoftwareUpdate
Preferences/com.apple.SoftwareUpdate.plist
Preferences/ByHost/com.apple.SoftwareUpdate.*.plist
Saved Application State/com.apple.SoftwareUpdate.savedState
Here, "*" stand for a long string of letters, numbers, and dashes. Leave the Library folder open. Try Software Update again. If it works now, stop here. Close the Library folder.
Step 3
If you still have problems, quit the App Store again.
Triple-click anywhere in the line below to select it:
rm -fr $TMPDIR../C/com.apple.SoftwareUpdate
Copy the selected text to the Clipboard (command-C).
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). Wait for a new line ending in a dollar sign (“$”) to appear, then quit Terminal. Test.
