I made a clean install of 10.10.3
I have enabled FileVault for the first time from the beginning of the installation and I let it to finish the encryption before I do anything else.
I have installed Firefox and updated iTunes to the latest version.
I have 7-8% battery left on my mac and I put it to sleep for about 6 hours, when I get back to it is asking to plug the power why?
I have left my MBP many times on sleep with battery under 10% for 24h and more and I didn't had this issue.
I connected the power and I wanted to restart it but I get a message that I cannot restart because there is a kernel update made but there is no application open and no update available in app store.
MBP 13r, mid 2014, i5 2.8, 500ssd, 8gb
Any thoughts ?
