It looks like you can finally hide purchases from the the App Store (and the iTunes store).
This may have been mentioned somewhere before, but I haven't seen it.
If you open iTunes and go to the iTunes store and click on 'purchased,' you'll get your list of purchases. From here, if you mouseover a particular purchase (movie, tv show, app), you'll see a little X in the top left corner. If you click on the X, you'll see a message: 'Are you sure you want to hide this purchase? You can unhide purchases from your Account Information page.'
Click the X and the purchase is now hidden on all your Apple devices.
[crarko adds: I don't know how new this is, but I'd not noticed it before either. Handy to know for things like the MLB app that have a new version each year.]
There is a way to add an iCloud Calendar in iCal in Snow Leopard.
Open iCal in Snow Leopard (if is up to date, it should be Version 4.0.4 (1395.7).
Select 'Preferences' from the iCal Menu.
Go to the Accounts tab.
Click the + sign to add a new account.
Select the 'CalDAV' option under the Account type.
Enter your 'User name' which is your iCloud .me email address.
Enter your iCloud 'Password'.
Now comes the tricky part; the 'Server address'. See below.
It will be of the form pXX-caldav.icloud.com (the XX would be numbers of the dedicated server). I was able to determine this value by sending an invite to another one of my other email accounts and clicking the 'Accept' button. This will open the reply in a web browser. If you look at the long URL, at the end there is a pXX value and that's the dedicated server.
Once that is done, the calendar will show up iCal. However, a few minor updates will need to be done so that it behaves just like in Lion's iCal.
Click the 'Server Settings' tab for your new calendar and update the 'Server address' with your pXX-caldav.icloud.com.
Next you need to update the 'Server path'. The way that it was configured is based on the MobileMe configuration and it needs to be updated to the iCloud. The value that MobileMe has is /principals/users/1.XXXXXXXXXX/ (The XXXXXXX is the dedicated number for your account. Update the path to /XXXXXXXXXX/principal/.
Update the 'Port' to 443 and select the 'Use SSL' option if is not selected.
Restart iCal in Snow Leopard. The Calendar will refresh.
[crarko adds: I haven't tested this one, although it looks very similar to the hoops you have to jump through sometimes when running the iCal service in OS X Server.
I'm one of those poor folks maintaining a mixed Lion/Snow Leopard setup holding out for some kind of update to Snow Leopard that will support a few basic iCloud functions like this. And I'm not switching from MobileMe to iCloud until either I see that, or have no other choice next Summer.]
I just accidentally discovered that in most typing fields in 10.6 or 10.7 (and maybe older as well) that if you hold down Option and hit Delete OS X will delete the last word you typed. If you hold Command and hit Delete it will delete the entire line.
I haven't stumbled across this documented anywhere and it will become part of my keyboarding repertoire. I confirmed it works in iChat, TextEdit, Mail and Safari so I would think it's part of the standard text input library. In MS Word 2008 and 2011 both command and option delete only remove the previous word.
[crarko adds: This is part of the Cocoa text handling system. I found an earlier reference in this hint but it's buried in there and so this particular usage may not be well-known. I trust nobody will be too alarmed if it's pointed out again.]
The new iPod nano Web page on Apple.com features a delightful, photorealistic Mickey Mouse watch face, one of the new clock faces available on the new nanos. Since the Web page for the new nanos is rendered in HTML5, you can ‘clip' this clock into the Dashboard on your Mac, and enjoy it long after Apple replaces the page in the future.
Right-click or Control-click on a white area of the page in Safari, and choose "Open in Dashboard" from the contextual menu.
When the white Dashboard selection box appears, hover over the Mickey Mouse face and click once. Resizing drag handles appear on the bounding box for the Dashboard selection.
Use your mouse to drag a selection box around the Mickey Mouse watch face, including a little white area around each corner.
Click the "Add" button at the top of the Safari window to confirm the selection, and the watch face opens in Dashboard.
The incredibly detailed and realistic movement of the second hands, and even the minute hands, make this a perfect Dashboard clock for any Disney lover. The watch face will even follow the time zone settings of your Mac to show the correct time and date wherever you are.
[crarko adds: HTML5 is a wonderful thing. This worked fine and gave me a chuckle.]
I was bothered by the fact that I could not easily change the state of a message within a conversation from 'unread' to 'read.' That is when one clicks on a thread in the middle pane of mail, one can read all incoming messages in a conversation, but this does not change the state of all the messages. You actually have to click on each individual message.
So playing around, I discovered that hitting the Right-arrow key unrolls the entire list of incoming messages in a conversation right in the middle column immediately under the cluster list item. It is now only a matter of navigation with the arrow key to read, and hence, change the state of message, and then come back to the original conversation cluster item. You can then close the list by hitting the Left-arrow key.
[crarko adds: This seems like a pretty handy shortcut.]
Sadly, Apple's decided to not include the popular Front Row with OS X Lion.
When Lion was released, it was found that you could install Front Row on Lion and it worked fine. That is, until Apple released iTunes 10.4, which changed the iTunes library format, so even if you installed Front Row, it couldn't see your iTunes content.
Here is how you can get Front Row working on Lion with the latest iTunes:
Install Front Row Enabler for Lion -- you can find a package installation at the very bottom of this link, under Attachments. You'll need to reboot after installing.
Make sure 'Share my library on my local network' is turned on in iTunes preferences.
To try this out once, run dns-sd as described in this post, using the command:
dns-sd -P "Local iTunes" _daap._tcp local 3689 localhost.local. 127.0.0.1 "Arbitrary"
Or to make this permanent, you can create a file in ~/Library/LaunchAgents called something like net.iharder.shareitunes.plist. The contents of that file should be the following:
If you use TextEdit as a scratchpad for typing in notes, and frequently close it without saving them, you wish to avoid Lion's longer wait to open a save dialog (which you don't always want) than the previous 'Do you want to save?' dialog.
While even an empty document (you typed something, then deleted it) will prompt for saving, a document with no undo history won't. I've found it's quicker on my system to use Command+Z to undo everything I've typed, then Command+W to close the window, than Command+W to close followed by a wait until I can dismiss the save dialog.
[crarko adds: That Save dialog does take a unusually long time to pop up. I'll make a guess this is because the system is doing its housekeeping for Autosave and Versions. Anyway, the method in the hint was definitely quicker when I tried it.]
Last week I was asked how it could be that a German Photoshop CS5 from one day to another 'forgot' the German language and only shows English menus and dialog boxes.
I thought this couldn't be -- maybe the German resource had vanished or the order of the languages in the System Preferences was wrong.
But the German localization files in Contents » Resources were there, and the German language was the first language in System Preferences so I did some research on the issue.
Photoshop CS5 needs a file named tw10428.dat in a subfolder named Locales » de_DE » Support Files of its application directory.
If you install a new scanner or camera there might be dialog box that asks if the TWAIN driver should be updated/replaced. In some cases this results in moving this .dat-File to the Trash and Photoshop forgets its multilingual capability. Check before you empty the Trash. In my case it was also possible to copy the .dat-file from another Photoshop CS5 installation.
This problem only occurs with CS5 as far as I can tell (my Photoshop CS3 doesn't have any Locales Folder in the application's directory, and I don't own CS4 to test it there) and as far as some forum posts and the actual problem tell me this only occurs in case of doing a TWAIN driver installation/update.
I imagine this might also occur with localizations other than German.
[crarko adds: I haven't tested this one. In some of their programs Adobe has offered a Repair installation option, and if CS5 has that it might also work.]
Ever since I wrote this hint, I was still looking for more and better ways to add attachments to Thunderbird. For one it has always annoyed me that the 'Mail PDF' function in the PDF part of the print dialog only works with Mail.app, even when Thunderbird has been set as default app for handling mail. The solution to this annoyance didn't occur to me until very recently.
In any app, for example Preview, open a document.
In the menu bar go to File » Print.
In the PDF part of the print dialog go to 'Edit Menu ...' (bottom line, last option in the menu).
A floating window appears: hit the + sign (bottom left).
Select Thunderbird from your applications folder (or any other app that will handle PDF files in some way) and hit Open in the Chooser Window
Now hit OK in the floating window
From the print dialog you can now send PDF versions of any document directly to Thunderbird as an attachment.
One caveat: Thunderbird does not show the disk space required for the PDF, it does that only after sending the file or after saving the file as a draft (save as draft, close, reopen).
