Browsing a few of the other boards and forums over the last few days, I noticed a few people have figured out how to make their Harmon Kardon Soundsticks function under OS X.
Navigate to /System/Library/Extensions/ and either rename (probably safer!) or remove the file AppleScreamerAudio.kext. You will probably have to be root to have permission to change this file. Here's how I'd do it via a terminal session. Comments are in [brackets], so don't type them!
> su [become root; you'll need to enter root password]
> cd /System/Library/Extensions/ [change to the directory]
> mv AppleScreamerAudio.kext AppleScreamerAudio.bak [rename the file]
> exit [ends root session]
> exit [ends terminal session]
Restart OS X and your Soundsticks should be working! Since you're disabling a portion of the system software, no guarantees on what else might break. However, others have reported success with no side effects.
If you regularly switch back and forth between OS X and Classic, and would like to keep all your bookmark and history information current, it's actually quite simple. This thread on the MacFixit Forums discusses a number of ways to do it, but "Toyin" has the best solution.
Start by making aliases of your Favorites.html and History.html files in OS 9. These are stored in System Folder:Preferences:Explorer. Take the aliases, and move them into /users/username/library/preferences/Explorer/. Replace the existing files (make a backup first if you wish), and (obviously, I hope!) replace username with your OS X user name.
Now whether you surf under OS 9 or OS X, your history and bookmarks will be common between both environments. You could probably reverse the process as well, and make aliases of the OS X files and place them in the OS 9 prefs folder (but I haven't tried that yet to be sure).
There's an interesting thread in the MacFixIt Forums about bringing Eudora mailboxes into the OS X mail application. It turns out it's possible, but requires a bit of file editing and directory structure creation.
Basically, you need to convert the Mac line-endings in each mailbox file to UNIX style line-endings, and then create a directory structure that matches what mail.app expects to see.
If you hold down the option key while resizing a "new-style" open panel that uses column view, the panel will switch to a single column mode that somewhat emulates Classic open panels (except that you navigate up the filesystem by using a horizontal scroller instead of the pop-up menu at the top of the window).
I think this just works for Cocoa apps, but I haven't checked any Carbon apps to be sure. I also can't figure out if this is a bug or a feature...
Frequently, the classic environment monopolizes the system. This makes the whole OS feel sluggish, because the the Window manager is trying to tear through all its code while sharing a huge number of resources with Classic. This happens on a lot of Unix platforms, and Windows as well. Unlike Windows, Unix and OS X provide a fine-grained way of alleviating this problem. It is called "renice". This command line tool wll allow you to finely control the priority of every program running on your system, including Classic. Typing "man renice" at the command line can give you detail descriptions of this tool, but I'll walk you through the basics (read the rest for the details...)
If you're running a spellcheck-aware application (such as mail), then you know misspelled words show up in red. Sometimes, though, the word is right, it's just not in the dictionary. "Dalgo" pointed out over on this MacNN forum that you can add any misspelled words to the dictionary by simply control-clicking (or right-clicking) on the word. You'll be given a menu with options to Learn spelling or Ignore spelling (among other choices). In all my mucking about with the beta, I'd never tried a right-click on a misspelled word! Thanks Dalgo!
Most screensavers feature a "fade now" corner which will instantly activate the scrensaver module. The built-in OS X screensaver does not inclue this useful feature. There is, however, a pretty good shortcut way of accomplishing the same thing. Here's how to do it.
In the finder (not in a terminal session), navigate to:
There have been some reports of people with totally dead Macs after running OS X. The causes seem very hard to pin down, but the common condition of the machines is an inability to boot off of a OS 9 CD. The machine is stuck running OS X, despite everything the user tries to fix the problem (including booting into open firmware, resetting parameter RAM, setting the system disk, etc.).
One final thing to try is turn the machine off, open it up, and pull the battery out of the motherboard. Wait a decent amount of time (five minutes or more), reinsert the battery, and restart. This should force your machine to forget about anything it thinks it knows, and go back to the factory configuration. Your CD drive should now boot the machine (when holding down 'C' during boot). I've seen reports of this working for more than one person, but there have been a couple poor souls that have tried this and are still non-functional.
Any other thoughts on potential solutions for those still stuck?
