Backup any user files you do want to save to a external drive and disconnect.
Most commonly used backup methods
This method will erase OS X, programs and users files off the machine, no recovery possible, it will be like a brand new machine when you reboot.
Reboot the computer holding the command r keys down, then select Disk Utility.
Select the Macintosh HD partition and Erase, move the slider to the middle secure erase selection (if available) and click apply, wait.
Once finsihed quit and select Reinstall OS X.
Preferably use a Ethernet cable to the router or modem (power it off/on), have your AppleID and password ready.
How do I securely delete data from the machine?
(If you have a firmware password set, you will see a entry line with a lock if you try to command r boot, enter your firmware password)
I have a MacBook pro it came with the 2 installation CDs ...after I erase disk what do I do? Am I goin to have to install the os that came with it and then go to apple store and redownload lion or how does that work I just want to completely clear everything out and start fresh safely
I never made a backup like an idiot.
I never made a backup but I don't have any personal files I wanna ke.ep after deleting the hard drive am I goin to have to use the installer CDs again or how does that work? Thanks for help
The installer cd's are for 10.6 Snow Leopard, your machine has 10.8 Mt Lion on it, thus the method I outlined above is for Mt Lion 10.8.
If you want to revert your Mac back to Snow Leopard, and you don't have any personal files to revert to 10.6, then follow this install method, be sure to erase the entire drive in Disk Utility.
Ok so no need for installer CDs cool so after I delete hard drive will an option popup for me to re download lion or how does that work since I don't have a backup made
10.7 and 10.8 are now downloaded from Apple's servers (well not Apple's actually, but Akamai, a data distributor)
So you need to follow the first post response I gave for 10.8, your Internet connection has to be fast, over 5Gb/s down and no interuptions.
Ok made it that far now I have 3 options
250.06 gb hitachi
Macintosh hd
Disk 1 Mac OSX base system
Which one do I go with and where do I go from here
Do u erase all 3 ?
Still out there buddy?
