TUAW Tip: Create an OS X admin user without a disc
Filed under: OS, Terminal Tips
Recently, I had to create a new admin user on an older 500mhz Power Mac G4 running OS 10.3.9. Needless to say, there was no 10.3 install discs to be found. What to do? Follow these simple (but powerful) steps.

First, restart the Mac while holding down the Command and "S" keys to start in Single-User Mode. Next, you'll see the UNIX boot sequence in white text on a black field. Don't worry, that's what we expected. At the prompt, type the following commands, hitting "Return" after each.
- mount -uw /
- rm /var/db/.AppleSetupDone
- shutdown /h now
Please be sure to type these commands exactly as presented here (sans bullets). "rm" is a powerful little command and if the syntax isn't right, you might unintentionally delete something important. Next, your machine will shut down. Turn it back on and you'll see the "Welcome to OS X" video, and be prompted through the process of creating a new admin user.

Other users on that machine -- including other admin users -- will remain intact. This is also a good way to change the password on an older admin account without the disc. Simply follow the same steps and, once you've logged in with the new account, change the password on your old account. Then, log in as the old account and delete the new one.

3 great uses for your screen shot app
Filed under: Productivity, Tips and tricks
Whether you use Leopard's native screen grab tool, or a specially designed app like Skitch, there's more you can use it for than just snapping a shot of your desktop. Here are three of my favorites:

No more cut and paste - I often have to replicate several pages of a content management system (CMS) that require me to enter tags in a field one at a time. I used to enter them on the first page, then copy the text, open Text Edit or Stickies, paste the text, then move on to the next page and flip back and forth between screens while re-entering tags on each page. Now I just snap a screenshot of the tags I've entered and use it as a reference on the remaining CMS pages.

File those registration receipts - After I've bought an app, I snap a shot of the receipt screen and store it in Evernote. Of course I also keep the copy the vendor emails me, buts it's nice having a backup in case my email client flakes out.

Make audio editing easier - While editing podcasts in Audacity, I often need to note the exact time of a clip. While it's easy enough to make a note with pencil and paper (remember those?), a screen grab lets me see at a glance exactly what other settings I was using at the time.
What are some of your more unconventional uses for the screen grab tool?

Do you suffer from 'appiphilia'?
Filed under: Humor, App Store

Do you download applications you don't even use? Do you stay up late, obsessively logging in to iTunes? If so, you may have appiphilia.

But don't worry: Appiphilia is treatable with Appien, from the makers of Extensionil and Kaleidoscept.

Talk to your doctor about Appien. For some patients, it can reduce the joy associated with buying new applications, meaning less time on the App Store, and more time doing the things that you love: like checking email or using Maps.

Only your doctor can diagnose appiphilia. If you spent more than $30 on applications in the last week, there's a good chance Appien can help.

Appien isn't for everyone. Side effects include nausea, projectile Zune ownership, and dry mouth. Tell your doctor if backing up your iPhone takes longer than four hours, since this can be a sign of a rare complication that requires immediate medical attention.

Talk to your doctor about Appien. Appien. Regain control of your iPhone.

DIY MacBook upgrade
Filed under: Hardware, How-tos, Odds and ends, MacBook
Yeah, so that black MacBook you bought a couple of years ago with an 80 GB hard drive isn't lookin' so hot now, is it? You know things are bad when you have to delete your pr0n videos to make room for incoming email. You'd like to swap out the hard drive, but your tech skills are sucky. What do you do?

Go to Instructables! They're always doing something fun over there, like showing how to install Tiger on a PC. There's also a recent post (surprise!) about how to upgrade your measly MacBook hard drive and preserve your existing data. Afterwards, you'll be doin' the happy dance, too!

Advance note to commenters: yeah, we know this isn't exactly rocket science, but for those who might be a little squeamish about actually yanking the hard drive out of their MacBooks, these step-by-step instructions should put their minds at ease.

Microsoft and FrontLine Release Solver for Excel 2008
Filed under: Enterprise, Software, Freeware
If you've been miffed with Microsoft since Excel 2008 hit the stores due to the removal of Solver from the popular spreadsheet application, it may be time to lighten up. You can now download Solver for Excel 2008 for free from the FrontLine Systems Web site. FrontLine developed the original Solver for Excel 2004, and developed the Excel 2008 version at the request of the Microsoft Mac Business Unit (Mac BU).

Solver is a linear programming / analysis tool for Excel that was included with Excel 2004 as an add-in, but dropped from Excel 2008 since it required Visual Basic for Applications (VBA). The Mac BU has noted that VBA is going to return in the next version of Office. In the meantime, Mac Excel users who rely on Solver's powerful analysis capabilities are now able to use the free download to perform their linear programming tasks.
