Like many others I had to install the Macbook Air Flash Storage Firmware Update 1.1. Once I hit the update button, the installation process started. However, the MBA didn't boot after the installation. So I'm not sure whether the update succeeded or not, although the update is listed in the System Information -> Software -> Installations, it seems to confirm a successful installation. After the update my MBA started to freeze occasionaly and some other issues started to occur, see list of issues below. I decided to install Mavericks, which succeeded after 3 attempts. After installation the system still wasn't running smooth. Disk utility said "Incorrect number of file hard links", I repaired the disk and it still says there are no issues with the disk. Please note I'm not using FileVault. I can't really work on my Mac after installing the flash update, issues are: - while moving the mouse, the rainbow wheel appears; - computer freezes out of nothing, which requires a hard-reboot; - Skype logs out frequently saying: "Unable to sign in due to a disk I/O error"; - using TimeMachine results in a frozen MBA; - using VirtualBox causes the MBA to freeze. I'm thinking of re-installing the flash storage update, but it's not possible since the manual installation says "This computer does not need this update". Also, the Console application doesn't report any issues related to the issues, which might be logical since the OS can't write log messages to the disk when it freezes. How can I solve this? Thanks in advance.
