How to format macbook pro

I have the MacBook Pro 13 "early 2011 model, which is now extremely slow. Can I switch from 4 GB to 8 GB ram?

The HDD is 320, but the news system occupies about 230 GB. I need to format the mac and install new OSX. I don't need all the files from the hard drive. Can anyone suggest a tutorial how to do in this regard? Should I install an earlier version of Mac OS x or the new version?

Your Mac can accept 16 GB (2 x 8 GB). I would like to replace a strip of 2 GB with a key of 8 GB.

First of all, make sure that your Mac has the update of the EFI firmware that adds the recovery of the Internet

Computers that can be upgraded to use OS X Internet Recovery - Apple Support

What OSX version is now on the Mac?

Without know that I would be starting for the recovery of the Internet

On OS X Recovery - Apple Support

Now try the Command + Option + R key at the start of the OS X Internet Recovery*.

Format the startup disk, and then install Lion. So yo can update to EL Capitan (and possibly others depending on which version of OSX have been used on Mac / your ID)

This is the Office Mac Pro forum. I asked that your post moved to the forum of laptop MacBook Pro or another appropriate forum.

    Hello

    So that the device bluetooth, webcam iSight, IR receiver and card internal memory to your Macbook Pro to work in your comments, you will need to install the boot camp drivers in your virtual machine.

    You can find the drivers on your OS X original installation DVD.

    After that, you can connect to these devices as if they were of USB devices.

    Your virtual machine should not be a boot camp VM for this to work, it's just that the drivers you need must be installed if your VM is a version of boot camp windows.
