Hi

 

I need some advice please about wiping a Macbook I bought off of ebay a while back (which I am now wanting to sell on due to upgrade).

 

The Macbook came with Photoshop and other programs preinstalled.

 

So far I have backed up all my data, apart from emails and deleted my files off the computer.  After moving all files to the trash, I’ve selected ‘secure empty trash’ which I believe rewrites over data so it can’t be recovered?

 

I have also deleted my internet browsing history and favourites, I had my bank and email webpage included in my ‘favourites’.  I haven’t deleted cookies yet

My questions is, is this enough?  If not are there any programs I can use to make sure that the deleted files and history are non-recoverable without reformatting / reinstalling the OS?

 

Because if I reformat and reinstall the operating system (if I can with no disk), then it will surely wipe off Photoshop and all the pre-installed other programs?

I had bank statements and other personal files saved to the computer.  If I have to reformat, is this enough?  Or do I need to replace the hard drive all together?

 

Much appreciated

Pauline

did you receive any disks when you purchased the mac? if not you may need to purchase them in order to fully overwrite your hard drive

Hi

Thanks for responding, unfortunately not, I didn't receive any disks.  Is overwriting the hard drive essential?

 

Thank you

its not essential but it is recommended to ensure any and all personal files and data are unrecoverable (aside from replacing the hard drive itself)

Right, okay, thanks.  As it stands, with what i've done so far, what is the likelihood of personal files being recovered?  If I replaced the hard drive itself, would this lose all of the preinstalled programs though?

Thank you

replacing the hard drive would require the OS be installed on the new hard drive so depending on who you take it to to get done it may just be easier to get them to overwrite the existing hard drive as opposed to buying a new one (places like geek squad have the capability to do this)

Okay, thank you.  I have seen hard drives online to buy with the OS installed, but my biggest concern is, if I replace the hard drive or overwrite it, it will lose the preinstalled programs (and I don't want to do that).  And wherever I take it, I don't think they will have the preinstalled programs (just the OS).

 

Do I have any other options of cleaning the hard drive of all traces of my files without overwriting?  Is 'secure empty trash' adequate?

 

Thanks again

discs that you can purchase will come with the preloaded programs that originally came with the computer on them and will install them so long as they originally came with the mac
