Hi.. I'm getting rid of my Macbook (3 months old) and getting a Macbook Pro... mainly for the firewire to record audio.

I've heard of the 'Eraser' software to clean up the mac...

Any alternatives that's better for mac? Is there a simpler way?

Any help appreciated.

Also... how do I erase the files and not the applications?

Does Eraser delete the files only?... or everything?

Confused

If all you want to do is erase files and leave everything else "as is":

Move them to the trash can - go to the Finder menu and select 'Secure empty trash'

Thanks for the quick reply.

Does that function secure the files currently present in the trash?.... or does it secure the trash's history?

What about internet history?

I want to sell the macbook as I bought it (excluding software /application updates)

Is there an easy way of doing this without downloading software?

sorry if this sound simple but I'm a mac noob when it comes to things like this.

If you're wanting to sell the machine - insert the original disk that came with the machine - restart holding down the 'C' key and reinstall

Well, I'd do more then just reinstall - if you want to totally cover yourself, when you're in the install DVD, before you go into the install process you can access disk utility and have it do a multipass security wipe, then reinstall the OS.

So the original disk has all the applications e.e. garageband, i tunes, safari etc

If I re-install... would it erase the applications?

You have 2 disks that came with the machine - they have everything it was shipped with.

Agreed. A fresh install will completely reformat the HDD and wipe everything. The reason that programs exist to recover deleted data is that modern OS's often don't actually delete the file - they merely tag those sectors on the disk as being writeable again, so as long is nothing is put over them, the data is actually still there. Also, they use what are called "journalised" file formats, so there is additional info about the contents of a sector of the disk hiding out on other parts of the disk. A reformat will put everything back to the way you had it when you first got it.

Use the multi pass security swipe which will write over your disk up to 37 times I believe, which is pretty **** secure. They said that most government offices only use 7 times through when they erase disks.

Note though that zeroing the disk (erasing it securely) will take a really long time especially if you do it more than once. See here for more info.

When I say long, I'm talking hours. If you do the 7-pass or more, leave it overnight.

For sure, for sure....

right...

I've done the 7 pass! And re-installed Mac OSX.. at the end of the installation it said that it had to restart.... so I clicked 'OK'....

Now the Macbook has started with the welcome and registration programme...

I don't wish to register myself with it again cause I want to sell it.... and I can't shut it down!

Also... if this is the case... how do I re-install the Applications DVD....

hmmmm

I've got offers on it already and I really want to get rid!

Thanks for the responses guys

Created a new temp. account in order to re-install applications.....

By now.... someone's bought it!

But .... how do I set it up as bought? I want to set it up so the buyer sees the 'Apple Welcome programme' when switched on....

????????????

My lack of mac terminology fails in Google!

Show user as anybody and password as 1234.

Pass on the install discs and this info to the new user and they can then change it to whatever they like. To get the welcome screen, sell after wiping the drive and l;et them do their own install. You are including the system discs with the machine? Otherwise you should not put an OS on it.
