Problem updating MacBook Air - error
I have problem updating MacOSX (10.7.4). The system answers: None of the selected updates could be installed. An unexpected error occurred.
MacBook Air, Mac OS X (10.7.2)
Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
What about my data? Does it change any settings or delete any data? What if I decided to upgrate to Moutain Lion. Will the problem remain during upgrading?
Your data are unaffected and none of it will be deleted.
Why don't you get this issue taken care of before you worry about installing Mountain Lion. What I can tell you is that upgrading a dysfunctional system only leads to a more dysfunctional system.
I have recovered the system as you adviced. Unfortunatelly the same error occured during upgrade. This is happening when the message is "writting files" after restart that is needed to install all updates.
Any idea what's going on?
I've just noticed even more. Safari is not working (it quits with a long list of errors) and iTunes says it can not open because some files are greated by newer iTunes version (I have updated iTunes only before). Mail.app is working and the same for Keynote, iPhoto (9.3.2). Fortunately I have CHrome to write this post.
Possible causes:
I have just upgraded! It looks like Thundebolt Software Update 1.2.1 should not be installed together with MacOSX 10.7.5 update. Now I have MAcOSX 10.7.5 without any problems. I had some with Safari (it crashed) but after 10.7.5 upgrade another one for Safari appeared and now it works fine.
I did not have a Thunderbolt Software Update in my list of updates. I unchecked all the updates except the Mac OSX 10.7.5 Update, allowed it to complete, and was then able to install all of the other updates after the machine reboot. Thanks for the tip on the OS Update. That got me going in the right direction.
I know this is an old thread, but I had same error when upgrade to Mavericks. I tried all possible solution in many other thread with no single luck.
Thanks for your solution, Greplo. it works very well and solves the problem. I enabled only the OS update, after done successfully, then followed to update the rest.
