Open TextEdit, create a new document, and then drag in an application ("Clock", for example) from the Finder. You'll see a clock icon appear in your document. If you save the document, it will be in "rtfd" format, which the Finder tells me is "RTF with attachments." If you look at the size of the file, you'll see that, in fact, the entire app has been saved with the document! Now open the file you just saved. Double-click on the application icon (the clock, in this example). The application launches right from TextEdit!
I have no idea as to how this might be useful; maybe it's a standard data format (but I've never heard of embedding an application in an RTF document?). There's nothing in Apple's help about this 'feature', so this is about all I know. Anyone care to shed any more light on the subject?
If you ever want to send email through one POP account, but with different sender info, there's a trick to doing so with mail.app. An example of this would be Yahoo! services, which allow one to have several public "personalities", each of which dump email to just one yahoo.com email address. In order to respond as the proper personality, you need to pick a different "from" address, even though you have only one POP account.
In mail.app, in the Account edit screen, you can enter multiple email addresses on the 'Email Address:' line. Separate each with a comma, and then save your changes. When you compose a new email from that account, you'll see a little pop-up for selecting which address you would like to use as the sender of the email. Very slick trick, and easier than creating an entirely new account.
You can't change the physical name, though - only the email address. If you need a different physical name, you'll have to set up different accounts.
Apple's mail.app stores most of the text strings it uses for creating replies, displaying dialogs, and composing new messages in an easy-to-edit text file. If you haven't relocated your mail.app, you can find the text file here:
When I tried to edit this in the terminal, all I got was gibberish - it's a Unicode text file. Opening and saving it in the GUI works fine; you just have to use a control-click on mail.app to "Show Package Contents" in a new Finder window, and specify which application to open it with (I used TextEdit).
Amazingly enough, the text file is even commented, explaining what each line does. You'll have to do some work to change the default reply string ("On March 23, robg wrote..."), as the date format strings are all variables - I imagine they match those used by the system date command, which you can view in the man pages:
Have fun customizing, but you should probably make a backup copy of the unmodified file first -- just in case! Any changes made take effect on the next launch of mail.app.
Panther update: As noted in the comment below, you now need to edit /System -> Library -> Framework -> Message.framework -> Resources -> English.lproj -> Message.strings. In addition, you'll have to reboot after making the change to see it take effect.
To synchronise my Visor, I add "Serial Port Monitor" to my start-up items. It can be found inside the Palm folder of the Palm desk-top software. This automatically starts Classic.
An icon is left in the dock with the Hotsync logo. This is normally a faceless background application under OS 9- and does nothing when clicked. However, when the Hotsync button on the cradle is pressed, it will happily sync your Visor.
I have found that it's best not to put the Hotsync Manager in the background during the synchronisation process as it can sometimes hang the Classic environment.
The MacNN boards are always interesting, to say the least. This thread discusses using your OS X box, in conjunction with cron and an Applescript or a shell script, to launch iTunes and play an MP3 at a certain hour each day.
I'm all for the integration of technology, but I think I'll stick to the old clock radio for early-morning wakeup duties! Still, it's an interesting article on what you can do with OS X...
Although you can't command+C copy from the "Address" line in IE 5.1 (we all hope it's a bug, not a feature!), you can drag the little '@' symbol to a text window and the url will paste where you drop it at. This also works in text fields on pages, which also don't like to be copied in IE 5.1 - just highlight and drag the text where you want it to go.
Some will say that the best workaround for this bug is OmniWeb 4.0 ;-).
This goes in the "Hmm, that's interesting" category ... or the "Check the prefs, bozo!" column, based on the comment below ;-).
I was taking a look at Apple's "Mac OS X: An Introduction for Support Providers" (a very good overview of OS X, by the way), and I was trying to browse the file with the scroll wheel on my Intellimouse. It seemed I could scroll down, but then it would get stuck. I could scroll up again, but not down. Similarly, at the top of the page, I couldn't scroll up any longer, but I could scroll down.
It took me a couple tries to figure it out. In the Preview app, the scroll wheel only scrolls on the current page. To move to the next or previous pages, you have to hit the next/prev arrows at the bottom of the screen.
I'm not sure if this is a bug or a feature! I like the way you aren't suddenly jolted to a new screen if you scroll off the bottom, but it's a pain having to hit the arrow button for each page.
All Cocoa apps respond to familiar commandline controls. This is what I mean, go into a Cocoa application (Omniweb, TextEdit, anything that is not Carbon or Classic) and click on any text field.
Type some random stuff, then press CTRL-A, it will bring the cursor to the beginning of that line, which is a common control in UNIX command lines. [Note: CTRL = the control key]
Read the rest of the article if you'd like to learn a number of other keyboard shortcuts for text editing in Cocoa apps.
[Editor's note: This isn't really just for UNIX geeks. How many times have you wanted a quick way to navigate around a text box without using the mouse?! Learn a few of these shortcuts, and free yourself from the mouse!]
I tried to install jEdit on my shiny new OS X v10.0 the other day, and noticed that it failed to install properly. It simply created a folder. So I headed over to Krisko's web page to see what was up -- he did the jEdit port for OS X. There's a not-too-encouraging message on his homepage:
"Looks like Java is pretty much broken under the final version of MacOS X. Lets hope they do something about it soon so jEdit works they way it should."
However, from the comments posted to this original story, there is a solution! 'Mojo' created a package from the latest preview release, and it works perfectly! Download it from his iDisk, linked in the Favorite Apps box on the left edge of the page.
Samba is a free UNIX program which lets you specify any number of 'shares' which will be visible to PC users on your network. Think of it as a PC/Mac version of Mac OS 9's file sharing. It's a great way to move files back and forth between the two types of machines, and it's actually (somewhat) straightforward to install and configure.
If you're interested in Samba on OS X, read the rest of this article for step-by-step instructions. I wrote it to be as simple to follow as possible, as I had zero UNIX experience the first time I installed it. Please post any questions or comments regarding the installation/configuration process, and I'll try my best to address them.
