Specific Questions about Password Protection

[FSMBP]

Just as a fore-warning: I have searched the forums and didn't find this specific question asked/answered.

I have a personal bank account spreadsheet. I would update this daily. Here's my question: is there a way Mac OS X can password protect a file/folder that can be constantly updated?

Yes, I know there is Disk Utility - Make a protected disc image BUT I would like to update this file daily.

And I am not interested in 3rd Party software.

Thank you in advance for help.

If you aren't willing to use a disk image or third party software, then no- it's not possible.

Excel and Numbers both will let you password protect the sheet

However, I am not sure I understand the question
Any protection will require you access through the password to update unless you leave it open (and that goes for the encrypted .dmg)

Sounds like you want to be able to update seamlessly, but others would need a password
I am not sure that is possible, but others may know a way

It's an Numbers spreadsheet. I would like to make it that it won't open the file unless the correct password is entered.

That's about the gist of the situation.

I may be confused on Disk Utility - my assumption is this: you can password protect a Disk Image BUT you cannot alter the contents inside. Therefore, it seems pointless for my situation. If that's incorrect, please let me know!

EDIT: Nevermind, I find the feature in Numbers - it allows to Password Protect on Open.

Thanks for the help MacDawg!

Glad that worked for you

But to answer your other question...
You can certainly change the contents of an encrypted .dmg
That is what makes it a great way to protect important files
