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?
