10.5: Find which items weren't modified by Time Machine System 10.5
Getting ready for work this morning, I walked into my office to find my 2.5 year old daughter mashing on my keyboard with the monitors off. Time out! After a quick check, it looked like no damage had been done. Later though, I tried to launch iCal with Quicksilver, and Quicksilver could not find it.

I looked at my apps folder (which was open apparently when she was mashing the keyboard) and saw that there were three folders with a bunch of jibberish for names. They were apps, but I wasn't sure which ones were which. Enter Time machine!

I tried to restore the whole apps folder, which I knew would take a while, but it told me Applications cannot be restored as it is used by the system. I selected all apps, hit copy, pasted the names into a text file and printed the file, meaning to open Time Machine and go down the list marking things off until I figured out what was missing.

With all of those items selected, I opened Time Machine and selected a backup from early this morning. All of the apps that were the same remained selected, but the ones that were missing -- the renamed ones -- were de-selected. I simply chose the de-selected apps and restored them.

This saved me a bunch of time going down the list and manually comparing the folder in Time Machine to my printed list. Now, off to Home Depot to get a lock for the office door!

It's much easier to set a login for all users and restrict your daughter's account. Plus you can use parental controls to limit the amount of time she'll spend on the computer.

ehm... I don't think his 2.5 years daughter has an account on his Mac... :) neither that she (still) needs one.

Cheaper, too. Saves the cost in time and money of adding a door lock if you use what's already on your Mac to keep, um, other typists of all kinds from causing problems.

You could just set your Mac to require a screensaver password, set the screensaver for a short time interval, and, as a bonus, add the Lock icon to the menu bar, so that you can lock the screen when it suits you. The Lock icon can be enabled from within the Keychain Access utility's preferences ("Show status in Menu Bar").

If you use your Mac instead of a door lock, the youngsters can still feel welcome while you protect your Mac, too. Yet another bonus! And Friday's not even over yet.

If you're too lazy to log out (like me), open System Preferences, click Security, click on the General tab, and click Require Password to wake this computer ... Much cheaper, faster and easier than running to Home Depot. And your daughter can happily continue her geek-like behaviour.

Reminds me how my 27 year old son, as a baby, would sit on my lap while I used my Apple II Plus. He would delightedly pound on the keyboard as though he too were doing something useful - until my Epson dot matrix printer starting printing, at which point he would howl with fear at the noise and I'd give him back to mommy. Today he's a high school teacher teaching - - - computer science (high school level).

You could also have just opened the folder, looked in Contents > MacOS and gotten the program name from there.

BBEdit (and the freeware TextWrangler) are good options for doing this type of directory comparisons:

E.g.:
- Open a new document in TextWrangler
- drag the new Applications folder in to the Textwrangler window
- Open another document in TextWrangler
- drag the backup Applications folder in to the 2nd TextWrangler window
- select "Compare two front documents" from the Search menu of TextWrangler

This will create a list of differences between the two directory structures that should be pretty easy to figure out what has changed...

I would just open Terminal and run a simple "diff /path/to/folder1 /path/to/folder2" to compare to directories. It gives me a nice, easy to understand summary of all the differences. Does TextWrangler provide something more than this?

TimeTracker.app does this
Authored by: SOX on Jun 12, '09 10:43:10AM
check out the free app TimeTracker http://www.charlessoft.com/
all it does is tell you what changed when with a gui interface to let you drill down by folder or file.

Restore in-use files from TM
Authored by: everkleer80 on Jun 12, '09 01:10:56PM

Haha getting a lock for the office is probably a better hint than locking your machine since unsupervised little ones (not to mention adults) can do much worse with expensive equipment than just renaming files!

Anyway I wanted to mention that I have tried to restore files that were in use before (ie. my entire /etc/ directory) and I just restored the folder under a new name and then connected the computer in firewire target mode to my MacBook (although you probably could just boot off of the OS CD or maybe into single-user mode or something) and then deleted the destination folder and renamed the one I had restored from TM. (In the case here I would go into TM on my iMac and restore the whole "Applications" folder to something like "Apps2" and then restart in FW target mode, open my iMac drive from my MacBook and delete the "Applications" then rename "Apps2" to "Applications".)

Simply uncheck "Allow user to administer this computer" in your account. Nobody should ever permanently work with administrator rights independent on operating system.
