El capitan wont install macbook pro 2010
I decided to update my software via the app store to el capitan but the installation always fails. At first, it would say the "no packages found" error. Then I tried again by changing the date to the year 2015 and with/without wifi, now another error comes up just five minuted before the installation completes with an error log with the options to view the log, save it, restart or shut down the computer.
Additional info: i have no back up of my mac. When I try to restart the mac by choosing another start up disk no options appear. And when I turn on the mac while pressing the Option key, the only disk that appears is the mac osx installation disk. Also, my battery does not work. I use the mac while it is plugged only.
