What to do about a deleted root account System
I installed the final release of OS X today. I set up my account just as I did with the public beta, except when I am in terminal at the command line, and I try to become superuser, it doesn't let me. It says "sorry" and that is the end of it.

I tried changing the root password in the NetInfo Manager app, but that was unsuccessful. So I deleted the root account! Now I can't do anything with netinfo manager and I can't "su" at the command line, as it says, "su: unknown login root."

What can I do without wiping out my disk and starting from scratch? Is there a way to create a new root user?

Any help would be appreciated.

ColorSync profiles won't transfer from OS 9 System
In OS 9, I used a ColorSync profile that made my screen look wonderful, but it won't work in OS X. It doesn't show up as a choice in the Monitor control panel as a display profile (in the Color tab). I've tried calibrating my monitor, but I can't get results that are as good as they were with this profile. If anyone could help me get this to work, I'd really appreciate it.

[Later that same day...] Well, I figured out my problem. Apparently, over the months that I've had the profile, it was corrupted through many moves and copies. So I just downloaded it again from xlr8yourmac, and it worked.

So if you're having trouble moving a ColorSync profile from OS 9 to OS X, make sure your profile hasn't become corrupted somehow; start with a fresh copy if you can.

Move the mail.app drawer to the left Apps
In mail.app, the default behavior for the drawer (which containsis to appear on the right edge of the window. Coming from Eudora, I much prefer to see it on the left, but there's no preference setting for 'drawer side.'

Solution? Elegant, simple, and (as near as I can tell), undocumented. Simply take a message in the inbox, and drag it towards the left edge of the screen. The drawer will magically switch sides! Mail.app will remember this setting the next time you launch it, too.

Thanks for this tip go to 'cricket,' who works for Apple on the mail team and hangs out on the 'X4U' mailing list, hosted by The Macintosh Guy (also in Portland, I might add - it's a hotbed of Mac addicts!). See the links area for a direct link to the mailing list subscription page.

Delete tip in terminal app Apps
When you want to delete a long text string you just entered in the terminal window (instead of pressing the backspace repeatedly), hit ESC and then backspace. This will delete backwards to the previous break in the text string.

Installing OS X final over the Public Beta Install
[Editor's note: See the comments for evidence as to why a clean install is probably the best way to install the Final...]

Is it safe to install OSX on top of OSX public beta without losing stuff ? Looks like I'll be upgrading on Monday, as Apple UK failed to deliver on the release date.

'Mac OS X v10.0 Review and Benchmarks' published Site News
Slogan-The Power of TenI have now posted my official review of Mac OS X version 10.0, which includes an extensive page of benchmark test results. You can either read the review, or jump straight to the Benchmark Results page. The review runs four pages, and includes information on installation, performance, bugs, and general observations. Let me know if you find it useful, or if you have any questions about anything I wrote.

On Friday night, we visited PowerMacPac, a local Apple-only dealer. They opened at 11:00pm, providing free cookies and soda, and gave an overview of OS X to about 75 or 80 "Macaholics" for an hour. At 12:01am, they began selling OS X. The first 50 customers received a nice t-shirt with a blue X on the front, and the slogan you see here on the back. The fact that you see a t-shirt picture here means that yes, I now own two copies of OS X (I bought the 40th copy at around 12:15am). The second copy will be going to my father-in-law sometime in the near future, but I'm keeping the t-shirt! They also had Titanium PowerBooks and the 22" Cinema Display in stock, so I guess I got out cheap! :-)

Editing preference files Apps
There are (already!) a number of programs around that let you edit the OS X preference files with a GUI-based tool as opposed to the command line. These give you easy access to settings such as dimming hidden apps in the dock, showing hidden files in the GUI, changing Cocoa apps default fonts, etc. Here are pointers to a couple of them that have been updated for OS X Final:

TinkerTool from Marcel Bresnik Software

osxsettings from jxzz.com

Enabling the root password (three ways) UNIX
Strong Warning: You should only enable root if you really really need it, really know what it's for, and realize the security implications of enabling root! You can do everything you need to do with "su do", so root is really not needed ... with that said, here's how to enable it - please understand what you're doing and why before you do this!

The "root" user (also known as the superuser) is the most powerful UNIX account. The root account can do anything to any file or folder, anywhere on the system. For that reason, it's considered quite dangerous, and only needs to be used (occasionally) by advanced users.

Because of the dangers of operating as root, Apple has chosen to hide the root account in OS X Final. However, there are a number of ways to enable it. The easiest is to boot off the install CD, and look under the Install menu for the "Password Reset" option. You can use this to change your own password if you forget it, and to enable the root account. This utility will not run if you copy it to your hard drive! It only works when booting from the CD.

Read the rest if you'd like to know how to do this from within OS X, and skip the CD-based reboot.

Move and corner your dock Desktop
One of the most-discussed features that appeared and then disappeared from interim builds was the ability to move the dock from the bottom of the screen to the top, left, or right sides, and to force one edge into a corner. These functions have returned in the final, and will probably be one of the most-implemented hacks on the system. I expect a full GUI tool for this within a week from someone, but for now, read the rest of this hint if you'd like the command-line instructions. They aren't too hard to follow, so don't be intimidated if you're new to OS X and/or UNIX.

UPDATE: If you'd like to do this the really easy way, get Docking Maneuvers, which puts a simple, effective GUI around the whole process! No UNIX required!
