MacBook crashes during boot
I'm having the following problems:
- after latest El Capitan update, my Macbook Pro (mid 2010) crashes (turns off) during boot.
- I'm unable to boot in safe mode, the only way is recovery mode.
- I've run disk utility with ok results.
- I've done PRAM reset with no effect.
- I'm trying to reinstall El Capitan as a last resort but I'm getting the following error message: "An error occured while preparing the installation. Try running this application again."
Currently I'm really stuck in the middle of nothing, everything I've tried goes terribly wrong and I have no clue what is going on.
Questa è una buona domanda?
