" Just installed 10.4.1 on my PowerLogix 1 gig G3 upgraded B&W, and CPU director is broken again. Tried to reinstall of CPU Director and rebooted no luck, still broken.
-Thomas C. "

I don't have a Mac running CPU Director but wrote PL about this tonight.
Another reader sent a note that the dial-up/modem problem seen with 10.4.0 wasn't fixed by the update.

"Hi, Lawrence R. from MC2 Computers here. I have confirmed that OSX Tiger has a major flaw with Dial up modems. (a reader also has seen this problem with his dial-up modem in a MDD G4 tower since Tiger was released and found no fix for it yet - even after repeated calls to Apple tech support-Mike) A client has come in with an iBook 700mhz and now with Tiger the modem will not dial out. Switching back to OS 9.2.2 will allow the modem to work. We even tried formatting an external hard drive, installing 10.4 and the modem still won't work.
We tried the 10.4.1 update as well, no change. We are now telling our clients to be careful upgrading to Tiger if they are using Dial up. 10 min later- CONFIRMED: In talking with Apple engineering, their statement is: "we are aware of the issue but do not have an ETA on a fix for the problem".
They also indicated that this problem is only affecting selected macs. Please tell all of your readers about this problem.
- Lawrence R."

Update - I asked for reports from Tiger users that were using a modem w/o problems and got 15 reports within hours, so it's apparently nmot a common problem. But if anyone finds a fix for those that do have a problem, let me know.

" The 10.4.1 Update delivers overall improved reliability for Mac OS X v10.4 and is recommended for all users. It includes improvements for:

file sharing using AFP and SMB/CIFS network file services using DHCP in wireless networks

user login when accessing LDAP and Active Directory servers

core graphics including updated ATI and NVIDIA graphics drivers

synchronization with .Mac

Address Book, iCal, Font Book, Mail, and Preview applications

Dashboard widgets: Address Book, Flight Tracker, Phone Book, and World Clock

creating and burning disk images using Disk Utility

compatibility with third party applications and devices
For detailed information on this Update, please visit this website:

As of 7PM ET I didn't see the update listed at Apple's support/downloads page yet but it should appear there soon. (Shortly after 8PM ET a page with the 10.4.1 update download appeared there.)
I'm applying this now on a G5 w/10.4.0 but if any readers find this improves/fixes or breaks anything, let me know. Thanks.

" Just a quick follow up to last week's exchange on the 8GB (Dual Layer) feature of iDVD 5.01. I was in a CompUSA store today and spoke to the Apple Rep. They had a new G5 sitting there with iDVD displayed (on a Samsung HD monitor via DVI- very impressive looking). As I hoped, the G5 had the DVR-109 drive in it, and iDVD 5 reported an 8GB disk capability.

The Apple rep hadn't been ware that older machines, even with DL drives could not get this feature. He called someone else on the phone and they concluded it was the Apple Firmware that enabled this. Apparently iDVD looks for a particular firmware before it will accept 8GB projects. Since one cannot even build a project of that size without the new G5's drives (Project Info doesn't show 8GB option), one can't even use Toast to burn iDVD disk images with.
(Note - as mentioned last week here, Apple's kbase doc on iDVD 5.0.1 dual layer support mentions that even if you could save a DL (dual layer) image, using a utility outside of iDVD to burn it "will not set the layer break according to the DVD specification and may result in playback issues"-Mike)

So even the very last G5 generation, if updated with a DL writer would not be able to do this. Of course Apple could unlock this capability in an update to iDVD, but currently it's part of their new G5 specs.
William R. "

I wonder if someone edited a firmware file of say the DVR-109 1.50 firmware update to change the version number to match the one in Apple's screenshot of their firmware version DVR-109 drive if that would show the option enabled.
The reader that originally reported the problem wrote:

"...There must be a checker in the 5.01 updater that withholds the package components for DL media... I figure I'll use PACIFIST to look in the 5.01 updater, see if there is anything obvious to extract...
