Resetting the IRL counter to "celebrate" the first kernel panic on the new iMac (yes, that's irony). No idea what the cause was. Newly installed software that was running at the time included a custom Intel build I had just made of [MLDonkey](http://mldonkey.sourceforge.net/Main_Page) and [Civilization IV](http://www.firaxis.com/games/game_detail.php?gameid=10). One of the first things I did after recovering from the panic was trash Civilization IV, just in case — it's only a game — and if I get another panic while `mlnet` is running I'll be trashing that too and never using it again. This machine is far too important to my work to take any risks. Paranoia is the order of the day.

You gotta love this. Actually, you gotta hate it. I just committed the sacrilege of daring to open Parallels and as my just comeuppance my machine immediately slowed to treacle speeds ultimately becoming unusable. In the end even the clock stopped updating and the mouse wouldn't move. At that point I had already waited through two songs (iTunes continued to play in the background) but when the third song should have started there was only silence.

Hot on the heels of the [last involuntary reboot](http://www.wincent.com/a/about/wincent/weblog/archives/2007/07/involuntary_reb_11.php) we have an absolute whopper today.

There are some applications that when they crash are capable of taking the whole system down. [Xcode](http://www.wincent.com/knowledge-base/Xcode) is one of them. I have no idea why or how they can do this. And I don't think it is actually the application's fault but something in [Mac OS X](http://www.wincent.com/knowledge-base/Mac%20OS%20X). That's my intuition anyway.

Very similar to the problem I saw [back at the start of this month](http://www.wincent.com/a/about/wincent/weblog/archives/2007/09/anchor.php): after installing a preview release of a certain operating system the DVD *appeared* as being mounted on the Desktop but both the Finder and the [Terminal](http://www.wincent.com/knowledge-base/Terminal) reported it to have no contents at all. I didn't try ejecting the disk but instead went straight to the System Profiler application, which beachballed for a long time before telling me that no optical drives were connected to the machine. The putatively non-existent disk burner then spat out the disc without being asked to, accompanied by a horrible screeching sound.

I've been too busy of late to post reports to my much-loved [Involuntary Reboot Log](http://www.wincent.com/a/about/wincent/weblog/archives/involuntary_reboot_log/), but I'm finally catching up with my first three entries since upgrading to the final version of [Leopard](http://www.wincent.com/knowledge-base/Leopard).

The most unpleasant kind of kernel panic: you leave the machine idle, leave the office, and come back to find the machine has panicked. Sigh. Had a bunch of unsaved work ready for tomorrow too, the kind you can't save (stuff in browser windows), and documents open in Finder and BBEdit windows ready for uploading. Hope there was no damage to the file system or the files. Sigh.

Another hard reset, this time not due to a fault in [Mac OS X](http://www.wincent.com/knowledge-base/Mac%20OS%20X) but rather due to my iMac's flakey construction (checking a USB cable at the back of the enclosure resulted in the wonky power socket temporarily cutting power to the machine). Another half hour lost while rebooting from the install DVD and running Disk First Aid.

So it turns out that [SuperDuper! definitely doesn't produce bootable backups](http://www.wincent.com/a/about/wincent/weblog/archives/2007/11/using_superdupe.php) on [Leopard](http://www.wincent.com/knowledge-base/Leopard). I had used SuperDuper! to move my old [Tiger](http://www.wincent.com/knowledge-base/Tiger) install [to a new volume](http://www.wincent.com/a/about/wincent/weblog/archives/2007/11/backup_obsessio.php); this was before I found out that SuperDuper! isn't comptaible with Leopard.

When I got home my machine, which had been up for about a day and had a bunch of in-progress work in open applications, started acting funny. New Terminal windows were totally blank (neither the command prompt nor any other text would ever appear), suggesting some kind of problem with the Directory Services infrastructure which is used on [Leopard](http://www.wincent.com/knowledge-base/Leopard) for user authentication. Strangely, everything else seemed to be working fine; I could open and close windows, launch applications, and write to files with no problems. (Sometimes you see situations in which you can't do those things; in those cases it seems that the cause must be some kind of resource exhaustion, like running out of Mach ports due to a leak.)

Just went out for two hours and when I came back the machine was displaying the grey screen of death (kernel panic), with the screen saver password prompt visible in the background.

Only a few days since the last kernel panic and I've just had another hard reset. This time the machine just froze completely with no explanation (mouse pointer frozen, clock frozen, no visible movement on screen or sound from the hard drive). This machine may well be on its last legs.

Like I said the other day, looks like [this iMac is dying](http://www.wincent.com/a/about/wincent/weblog/archives/2008/01/imac_finally_dy.php). This time the machine simply turned itself off when I bumped the desk with my knee; it could barely even be called a bump.

Two kernel panics while trying to boot from a just-installed copy of Mac OS X. I won't bother telling you what version of the OS it was...

Lesson of the day, never double-click the application you can find at `/Developer/Applications/Performance Tools/CHUD/Hardware Tools/Reggie SE`. I just made that mistake, out of curiosity, and it hard froze my system. By "hard freeze" I mean that not even the mouse pointer would move, the clock stopped updating, the machine did not respond to pings from elsewhere on the local network, and the only thing that seemed to be working well were the fans (roaring like hair dryers).

In an endless Build-Debug-Edit, Build-Debug-Edit cycle for [Synergy Advance](http://synergyadvance.com/), click "Debug" and wait for 10 seconds while Xcode thinks. Notice that the music has stopped. Switch to Safari, which has a list of MP3 files in a window. Command-Click a couple of MP3s with the intention of opening them in tabs and previewing them (using the Quicktime plug-in). Safari beachballs.

Much like [last time]() but with an updated version of the OS, again a panic on boot. Tried unplugging the USB cable connecting the UPS and was able to boot.

This time it was my fault, kind of. Trying to do some low-level Mach stuff to work around a bug in Mac OS X, I ran into a different bug in Mac OS X, and this one was enough to cause a kernel panic. From a regular unprivileged process. Ouch. A strong deterrent from continuing that line of development...

This was a novel one and the first non-kernel panic involuntary reboot I've ever had with the iMac. Today I was waiting for a compile to finish and was wishing a friend a merry Christmas over IM when I noticed that my keypresses weren't resulting in any output. Mouseclicks didn't work either although I could still move the pointer. Mousing over the Dock yielded nothing. Yet iTunes continued to play and the seconds on the clock continued to update smoothly.

You could argue that this one is my fault but I like to blame it on the Mac OS X dependence on NetInfo for user information.

After a day spent trying to get the minimum number of development tools installed onto a clean install of a certain version of a certain OS, I finally decided to throw in the towel and give up. Unusable. The thing has a list of reproducible, hard-core bugs as long as your arm which I won't talk about here. When I tried to shut down the thing hung at a blank screen; after waiting about five minutes it was time for a hard reset. I am sure I could have waited five hours or five days and it would have still been stuck at that same point.
