Buy a PC next time. A fraction of the cost and will work long enough to get your moneys worth.

What is Startup Manager?

Tried every suggestion on the list at minimum twice each. The only improvement is now the built in display lights, whereas, only the external monitor would after installing the update. There are zero externals attached to the MacBook Pro in any way. I and several hundred thousand other people pay monthly accounts online at the first of the month. I have followed the instructions on how to restart my MacBook Pro as per your instructions, all seems to work according to your instructions until i get to the password stage.

It accepts the password then just sits there… I am so frustrated. Sorry to hear about your problems with your MacBook Pro. Yes, that must feel very frustrating indeed. Since you get stuck in the password stage, are you entering an admin versus a standar user account password? Another option is to restart your Mac in Safe Mode add Shift key at restart and see if it detects any issues—if so, just starting it up in Safe Mode often fixes problems. I own a mini mac A late and my problem is that it stuck at the white screen with the apple and the loading bar… I have a usb keyboard not mac and I cannot enter recovery mode nor safe mode….

Can you help me please? Is there any way to install the OS from another machine, like a PC with win7? Thanks in advance for your reply! When prompted, type Y for yes to confirm that you want to erase the volume, then press Return. Terminal shows the progress as it creates a bootable installer. I have a MacBook Pro.

First, plug your MacBook into a wall outlet and let it charge for a few hours undisturbed. Then, try doing a Safe Boot holding the Shift key and see if it launches. Alternatively, try booting in Recovery Mode holding Command and R keys together and run disk utility to check your HD.
