The small icon in the Get Info window in OS X is useful as an application launcher, too. If you have an application selected in the Get Info window, a double-click on the icon will launch that app. A double-click on a document icon will launch that document's associated application. Finally, a double-click on a folder icon will open a Finder view of that folder.
As always, you can still single-click and cut-and-paste custom icons.
As I noticed my system time slowly drifting away from my WWV radio-clock time, I decided to re-check Date & Time settings and found that time wasn't being set automatically. Here's one way to keep your clock synchronized.
Open the Date & Time control panel, and go to the Network Time tab. Make sure Network Time synchronization is OFF (click the button to stop if necessary). Select MANUALLY, and enter an IP address for a Network Time Server (NTS) into the NTP field. There's a listing of appropriate servers at:
If you really miss the old "Control Panels" folder, you can (more or less) recreate it using the dock. Simply navigate in the GUI to the /System/Library folder, and then drag the "Preferences" folder onto the right end of the dock.
Control click on the folder, and you get direct access to each the system prefs! Thanks to the X4U mailing list for this one...
As an administrative user, you can create a new user account by using the System Preferences: Users section and simply adding a user. Similarly, you can delete a user. The problem is, the deleted users directory doesn't go away, it is just renamed in the /Users directory to "username Deleted". You cannot throw out the Deleted directory using the finder, even as an administrative user. Here is where being able to get to the Unix core is so great.
With administrative power, you are one command away from deleting that unwanted directory. You are also one command away from deleting everything on your system. Here is the command:
sudo rm -rf /Users/"username Deleted"/
If you were to mistype the username and accidently remove your account, there would be no recovering your files. The destructive potential of the rm command is probably one of the main reasons the root account is somewhat hidden (just my opinion).
[Editor's note: You can use a slightly safer variant of the same command by simply adding and "i" to the "-rf" string; the revised command would read sudo rm -rfi /Users/"username Deleted"/ -- this will have "rm" ask you to confirm each file deletion]
Don't fear the command line, it can be a really great thing. But please, use caution anytime you have to use root privilages to rm a file or do anything else. Other than that, learn vi! Enjoy the Unix that your Macintosh is running.
Anyone know how to move a single user's home -- not the entire 'Users' directory? I travel back and forth between two machines and would like to carry my "home" with me on an external hard drive. I tried editing the home directory in NetInfoManager, but it didn't seem to work.
There's an interesting discussion in this MacNN forum about replacing the "Buy Mac OS X Software" menu item in the new Apple menu with something of your own design.
With some (relatively) simple editing, you can insert your own command to replace the one Apple has provided.
Personally, I haven't missed the Apple menu at all, but I know some people find it essential. Although this is far from the return of the OS 9 Apple Menu, it's interesting if you'd like to know more about customizing your system.
My computer is on DSL behind a router that uses DHCP. The connection was dropped this morning and Mac OS X's DHCP did not log back and in and get the new information from the router. I had to change the Network preferences to BootP, close the panel, and then return and select DHCP again. OS X logged back in to the router.
Is there any way to make DHCP log back in automatically?
If I plug in my mouse while the iBook is sleeping (lid closed) when I wake it my screen comes up for a few seconds and then goes dead. Nothing will wake it, except a complete cold reboot. Also my freshly charged battery went totally flat. This happened twice with 2 different batteries before I realized what was happening. The same crash occurs with the power plugged in except the battery appears unaffected (as expected). I am posting this to Apple but thought I should warn everyone as it can stop you dead if power isn't handy.
