Hello

Why must this feature MUST be added ?

The Numbers team build a template of what to put in Numbers and what to drop.

It seems that the Password protection was not a useful feature from their point of view.

Your point of view is different, *go to "Provide Numbers Feedback" in the "Numbers" menu*
and describe it.

If you convince them, maybe they will add the wished feature in the next main release in iWork'09 😉

That is ridiculous! I converted from Excel to Numbers because I like Numbers better (you can create sexier spreadsheets), but I have many financial spreadsheets which I want to password protect (lock) so that no one except me and my wife can open it up. This is just in case our computer gets hacked. You don't think this is something that is important? What, do all Mac users just love to share all of their information with everyone?

Don't get it. I hope they add this to the next version of Numbers.

The result of your hope is NIL.

Apple engineers are not reading this forum.
This is why I often wrote:
If you want a new feature: *Go to "Provide Numbers Feedback" in the "Numbers" menu*, describe what you wish.
Then, cross your fingers, and wait for iWork'09 😉

To protect datas from curious persons, we already have a good tool:
*Store our files in an encrypted disk image.*
It seems that this efficient soluce is too simple for XL accustomed users 😉

I agree that the feature is missed, but you must understand that one of the goals in the design of Numbers was to eliminate feature bloat. MS Office suffers from this illness and I for one am willing to work around minor shortcomings to gain performance and ease of use.

An encrypted disk image is a satisfactory workaround. It's easily created with Disk Utility and only requires a password when you mount the image. After it is mounted you can read and write from the DMG file without any further security access required. When your done with the files just eject the image and your documents are secure.

Hi,

encrypted disk-image, how??

i, like the original poster, would like to lock my spread sheets. however, i don't mind working around things (as a matter of fact, using an encrypted disk image is a great idea, and its something i wish i would have thought about before for millions of things). my question to you: how do i make an encrypted disk image to put things in?

i absolutely agree with what you said. i've switched to iWork today. i thought, "nice, an escape from a documents program thats nearly as heavy as Adobe is." so i hoped what you said: "eliminate feature bloat" would be a goal accomplished. i don't know what the deal is, but every single time i enter a number into a cell, i hit "Tab" and the color-spin wheel comes up immediately. it seems like Numbers is having trouble processing what ITS doing. i realized using the left "arrow" helped avoid the spin-wheel, but have plenty of instances already in the less-than 12 hours i've had iWork '08.

Hello

Use Disk Utility which is factory installed in Applications:Utilities.
Select "New Image"
Select "AES 128" in the second local menu (Encrypt)
Define a size matching several times the doc's size so Numbers would be able to expand the XML embedded file and store some old versions for safe. It seems that the minimal requirement is a factor between 2 and 4.

When a file is frozen I uses factor 2.
When it is living I uses fctor 5.

Hi,
I'm trying to do as you suggest, however I'm a bit confused. I've got my Numbers file that I want to protect. How do I create an image from only that file? When I open Disc Utility, the options on the left bar are only of my HDs or peripherals. It doesn't seem to allow you to chose ONLY one file...
Can you please expound on how to get only that file as the choice for your encrypted disc image?

Jan 28, 2008 2:04 PM in response to Kitebarbie

Hello

I will do my best to explain in "English" :

create a blank disk image of the required size.
My own choice is 5 times the size of the true numbers document
When it is created, you open it (of course, it will ask for the password).
you move the document in the white disk which will appear on the desktop.

You would be able to work with the file when the image disk is open.
Close it and its contents will be encrypted.

Next time, when you will try to open the disk image, you will be asked for the password again.

But I'm sure that Apple's wording, in the help or at:
http://docs.info.apple.com/article.html?artnum=107333

is more clear 😉

Hi Kitebarbie,
I should have been more explicit.

From the OS X help file:
About creating a disk image to transfer or back up information
You can use Disk Utility to create a disk image of a single device, folder, or volume. You can use the disk image to transfer files from one computer to another, or burn the image on a CD or DVD and use it to restore the contents of another disk. To learn more about disk images, open Disk Utility, in the /Applications/Utilities folder, and choose Help > Disk Utility Help.

From the Disk Image help file:
Creating a blank disk image
You can use Disk Utility to create a blank disk image to store files. Usually, when you create a disk image, you gather the files you want to include into a single location before you create the disk image. With a blank disk image you can add files to the image at any time.

1. Choose File > New > Blank Disk Image.
2. Type a name for the disk image and select where you want to save it.
3. Choose the size of the disk image from the Size pop-up menu.
4. To require a password to open the disk image, choose "AES-128 (recommended)" from the Encryption pop-up.
5. Choose "read/write disk image" from the Format pop-up menu.
6. Click Create.

To add files to the disk image, open the image in the Finder, which creates a volume on your desktop, then drag files to that volume.

Run a test on placing it on your desktop. Copy files into it, again this is a test, don't move them.

As you can see help files are very useful.

Let us know the outcome.

Sincerely,
RicD
