I discovered a bug in Logic Pro by missing the last movement of a symphony recording: if you unplug your headphones, Logic stops recording. I'm assuming this is because it switches from line out to speakers.
The solution is to route the output of Logic to Soundflower. Launch another audio application (e.g., Amadeus Pro), set its input to Soundflower, the output to headphones or speakers, then launch any operation that allows monitoring the signal. (In Amadeus, open a real-time sonogram window and select Play Through.) Unplugging the headphones now no longer interrupts recording in Logic Pro.

I use Dropbox to sync files across my Macs, but also to collaborate with others on several projects. One day, I woke up to find the disk space on my MacBook Air had dropped substantially. I started poking around, looking for large files, swap files and the other usual suspects. I eventually found a hidden folder inside my Dropbox folder: .dropbox.cache.
Looking inside this folder, I found that it contained three dated folders, for the past three days. (For example, 2012-03-01.) Inside this folder were a number of files, and since on one shared project we use a standard versioning system, I was able to see that there were subsequent versions of these files, with names indicating that they had been deleted.
All in all, I recovered 8 GB that day, because there were two projects where people had change a lot of files. On a desktop Mac, this won't usually make much of a difference, but if you have a MacBook Air, in particular, without much disk space, you may suddenly find yourself out of room. So, if you see a sudden decrease in disk space, you can check this folder. If you use Terminal you know how to get there; if not, you can open it from the Finder. Choose Go > Go to Folder, and enter ~/Dropbox/.dropbox.cache (assuming that your Dropbox folder is at the default location at the top level of your home folder; change the path if it is not). You can delete the folders with no worry of losing files.
The MacDrifter site posted a helpful tip: Messages works well as a shared clipboard between your Macs and iOS devices. Either device type can be used for sharing text or images, but files can only be shared from Macs to iOS devices.
It works well and it seems easier than any of the third-party solutions I've tried.
Here's the two steps:
Copy a link, photo or text and paste into iMessage on Mac, iPhone or iPad.
Send a message to yourself.

I was typing in Pages today, and forgot that I had turned my laptop's special F-keys off so I could play a game, and discovered something interesting.
If you are typing a word in any supported apps (Pages, Keynote, Numbers are what I have tried, there are probably others), and then press F5 (at least on a laptop) in Lion, then a menu will pop up with any other words in the Mac's dictionary that what you have already typed could be included in.
To expose this option, go to System Preferences » Keyboard and check 'Use all F1, F2, etc. keys as standard function keys.'
For example, when you type the word world, then press F5, the menu will show 'worldly,' 'worlds,' etc.
[crarko adds: I tested this, and it works as described. F5 is the standard Cocoa Text System 'Complete current word' function, that's often masked by the alternate uses of the function keys.]
Back to basics -- use keyboard shortcuts to open and close the fonts window and the color picker window in text editing applications.
Here are two quick and easy shortcuts to keep in mind for use in most text editing applications. Don't bother with these in Word, they don't apply. Try them in TextEdit instead.
The first you probably already know. It lets you open the font selection window. It's Command+T.
The second you may not know, but it usually works in applications where the first one works. It's Command+Shift+C and it opens the Mac Color Picker window. Two quick tips about this window:
1) If you click the magnifying glass icon, you can choose any color available on your Mac's screen, and
2) you can drag a color from any point inside the rectangle near the top of the window into one of the squares at the bottom to store it there for future reference. Try dragging the bottom right corner of the window (and/or the right edge, if you're using Lion) if you need more squares.
One last thing, use the same shortcut to hide the windows as you used to invoke them.
[crarko adds: In BBEdit, only the first shortcut works (not surprising). Both shortcuts worked in the iWork and iLife applications I tried them with, as well as TextEdit.]
Using Apple's new app Messages beta you can discover who you can send Messages to.
In Messages, press Cmd+N to open a blank message window. In the 'To:' field, which is highlighted by default, begin typing a name. A list will appear showing all the possible completions. Once you have typed one unique name, the list will show all the addresses known for that person, and will put a blue chat bubble next to any item that you can send a Message to. This works for both e-mail addresses and phone numbers.
[crarko adds: I don't have the beta handy so I haven't tested this one.]
When looking at the new Messages.app preferences I realised that you can get it to run applescripts on various events.
Under the Alerts Tab in the Messages.app preferences, you will find a list of Events under the drop down Menu 'Event.' Each event has its own set of independent options . All include a 'Run an AppleScript script' option. These scripts can just run on every instance of the chosen event.
But you can interact with the Messages.app with the script the same way you would in iChat.
So if I wanted to, for example, have my Mac send me a message, when an event occurs that matches certain criteria I can use the iChat syntax.
using terms from application "iChat"
on message received theMessage from theBuddy for theChat
--display dialog (theBuddy's name as string)
if theMessage is "some Text" then
-- do something
send "some info" to theBuddy
-- do something
send "some other info" to theBuddy
end message received
end using terms from
Messages.app at the moment registers itself as iChat, not Messages. This most likely will change when the final release is out.
I did not use iChat that much. But I will be using Messages.app a lot. What makes this even better is I can send Messages to myself to get my Mac to do things.
[crarko adds: I'm sure in Mountain Lion there will be some interesting ways to combine Notifications with Messages, if the Sandbox permits it.]
I discovered a keyboard shortcut for moving messages to favorite mailboxes: Command+Control+number.
OS X Lion added a Favorites Bar to Mail where the user can keep frequently accessed mailboxes. The Command+1, +2, etc., shortcuts that used to work in 10.6 for Inbox, Outbox, Drafts, etc., are now associated with these favorites in order from left to right. While reaching for a different shortcut, I just discovered an undocumented shortcut for moving selected messages to one of these favorite mailboxes.
Just add Control to the shortcut. For example, Drafts is in the third position on my Favorites Bar, so Command+Control+3 moves a selected message to Drafts. The only requirement is that the destination is a regular (not smart) mailbox.
After much searching, I have finally found a way to correct misspelled words without using the full Spelling interface and without using the contextual menu, as that requires using the mouse.
I use the keyboard as much as possible. I much prefer it to using the mouse. I don't claim to know all the shortcuts but the ones I know, I use all the time.
And for some time, I've been looking for a way to correct spelling for cases when auto-correct doesn't work. I thought it should have been easy to do.
The only way I knew how to do it was right-clicking the misspelled word, which brings up a contextual menu the top of which shows suggestions followed by other options such as 'Ignore spelling,' 'Learn spelling,' and so on. But this is no shortcut and requires using the mouse.
After all this time with Lion, I've finally found an answer. Yes, Lion has auto-correct, but it can be switched off or you might click Escape before it can auto-correct and now the word on the screen is misspelled.
So, here's what to do:
Find a nicely misspelled word.
Add a space at the end.
Now, using the arrow key, move the cursor so that it's after the last letter in the word.
Wait a moment.
You will see a list of words appear and a small grey 'x' at the end. Use the arrow keys (down, left, right) to select the word you wish to use instead and press return.
[crarko adds: I tested this in TextEdit, and it works as described.]
By default, Mail will mark a message in a conversation read after a short delay. To adjust the short delay (for example, to remove it), use the following command (replacing 0 with the desired time in seconds):
defaults write com.apple.Mail MarkAsReadDelay 0
To revert to the default:
defaults delete com.apple.Mail MarkAsReadDelay
As far as I can tell, there isn't a way to affect the delay for single messages.
