Gig-E PM (400-450DP-500DP G4)users...
...has anyone had a good/bad experience with the OS 10.1.5 update. I'm looking forward to a few of the parts of the update, but I've heard horror stories about KPs from other people who own Gig-E PMs. Particularly, StarfleetX, did you ever successfully get your system working under 10.1.5?
Comments
When attempting to use single-user mode, I find that the torn folder happens because messages are thrown up with various errors related to "com.apple.driver.AppleKeyLargo" and that it cannot be loaded. Ideas anyone?
Oh well. <img src="graemlins/hmmm.gif" border="0" alt="[Hmmm]" /> Fortunately, I don't have to restart very often -- that's the only time I actually have problems. The system runs fine otherwise. It's just these other updates and "fixes" Apple keeps sending us that I restart for.
No networkingproblems here.

On the other hand, 10.1.5 installed cleanly on my iBook... and I haven't noticed any problems in 10.1.5 on the Powermac since I re-installed everything from scratch.
Despite that X.1.5 works quite well for me.

My DP 500 seems to run fine. My main system, a 450 Cube, which I use far more frequently as it's always on (noise factor) runs fine as well under 10.1.5. If you could be more specific about problem areas I'll try them out.
You have the honor of reading my first post in these forums. ;-) Let me say that I'm a software developer and have experience running OS X on several machines since the first Rhapsody developer preview. I think it's fair to say that I have a lot of experience in this area.
My main system is as follows:
Power Mac Dual G4/450
512 MB RAM
40 GB + 80 GB Maxtor--we'll see how long this lasts ;-)
Radeon 32 MB in AGP slot
Apple 17" LCD
Harmon Kardon SoundSticks (USB)
I also have the usual assortment of Firewire and USB printers, scanners, mice, etc.
I have run every major and minor update of OS X on this machine and have never had a kernel panic that wasn't the result of 1) bad hardware, 2) third party driver issues, or 3) corrupted disk. I installed 10.1.5 the day it became available and have had no problems. When I say "never" I mean "never in a final, public build."
Here are the problems I've had:
1) The original 30 GB IBM "Deathstar" hard drive died a typical death, as did the 60 GB replacement drive. I'm just waiting for my two current Maxtor drives to suffer from the "two beeps" problem. <sigh>
2) Bad memory. The original 128 MB RAM module that shipped in my machine is damaged. I was having crashes and kernel panics like crazy all of the sudden for no apparent reason. After removing all but essential hardware, reformatting my drives and reinstalling several times I finally was about to call Apple when I decided to run the Hardware Test CD that came with my machine, which is how I discovered the bad memory. Oddly, I've seen this same problem on another dual processor G4.
I'll metion this here because I haven't seen it anywhere else. After updating to 10.1.5, I notice that when playing Audio CDs or MP3s, I hear some distortion in my SoundSticks that was not evident before. I haven't had the time to track down what the cause is.
StarfleetX, I have two suggestions for troubleshooting your problems:
1) Use your Hardware Test CD to find bad RAM. Seeing com.apple.driver.AppleKeyLargo may be completely misleading in that it just so happens that this driver is getting loaded into a place in memory that fails sometimes. I'd even go as far as to say that the initialization code for the driver is getting loaded into bad RAM so when you boot up, if the memory works correctly, then you're safe, and if not, you're toast.
2) Reset your power manager. As you probably know, KeyLargo is the I/O controller. The most common problems relating to this are power manager issues. The other thing I can think of is a damaged IDE drive cable. To reset your power manager, check out Apple Knowledge Base article #95037.
For those of you worried about updating, I cannot stress enough that before you apply an OS X update, make sure your disks are in good condition! Start up from your OS X CD (or from OS 9 if you wish) and run Disk Utility or Disk First Aid, respectively. I have never personally seen an OS X machine suffer from the "hanging during optimizing" problems that people encounter but it always turns out afterward that there is directory and permissions issues that were probably evident before the update.
One last thing to stress is this: don't mess with your OS X installation from OS 9. This is asking for trouble.
Welcome, sir.

Ok, I've officially gone to 10.1.5 and had no problems so far... I was trying to avoid having to buy a hard drive, but found myself with a KP BEFORE I UPGRADED! So I took my computer into the local Genius Bar and they tryied to fix it, only to tell me that I needed to get a new hard drive because my original one was so corrupted that OSX couldn't even be reinstalled properly.
2 days and $100 later I have two hard drives in my computer, each one running OSX fine.
LESSONS LEARNED:
1)BACKUP and completely re-initialize your HD when istalling OSX when possible
2)CREATE backups often
3)RUN Disk Warrior on a regular basis.
4)KEEP a small partition with only MacOS9 on it so that if you do screw up OSX, you can still boot your computer.
