    Hey!
    I am using the 2012 MacBook Pro 13 Retina and suddenly after browsing the web in Firefox my macbook heated up super hot and nearly froze. Then after 5 minutes after I close Safari which crashed in the meantime, I had 8gb more free space. What happened? How can I track corrupted or lost files?

    Thanks.

    It could be either cache files or swap file space on the disk that was wiped when the machine rebooted, and that would be normal. Is everything working okay now after the reboot? You might try Disk Utility to do a verify disk and see if it reports any errors.

    kernel task is sort of the main OS process that manages the system. Typically kernel task itself is not the problem, but rather some other process kernel task is managing that is causing problems.

    If you have 8gb of ram, it is likely that the swap file was deleted. A new one will be generated next time you sleep your computer for a while.
