It would seem to show that the issue might have something to do with the wireless networking on your desktop machine. Or maybe just to do with having that machine on a network where file sharing is going on?

Quit safari, and ran the same terminal command, this time having the Desktop's startup drive (bkprG4) mounted onto my ibook. didn't copy any files over but just browsed through bkprG4's files (which has a worse affect on iTunes than uploading via Safari). This resulting text file is here.

I note two things from that output:
- lots of AppleFileServer activity
- lots of reads from syslogd
The AppleFileServer would be due to the file sharing - maybe that is what is taking the CPU and causing the jerkiness (die to some incompatibility or bug or something)?
I'm not at all sure what would be causing the syslogd (daemon that handles log messages from the system) to be doing all those reads. But it points out that you should check the system logs (using /Applications/Utilities/Console.app)

Could this mean it's a hardware issue? Or, more specifically, a combination of my hardware, which hasn't changed in a loooooong time, and OS 10.4.6, which I installed for the first time after I had reformatted my whole machine?

Does your desktop machine have any 3rd-party hardware? If so, the drivers for it might not be compatible with 10.4.6 (might need an updated version of the drivers).

Do you need to keep the G4 on WLAN ?
It would be a getting-around-the-difficulties way of solving the problem, but unless running the cable is really very complicated, it could be a solution to be considered.

Hi there.

Sorry Hayne, I didn't see that this thread had gone over two pages... :S

3rd party hardware...
Nothing that I could imagine would interfere... HP Printer, Agfa scanner, Billion Bluetooth dongle (don't think that had a driver) That's about it... I'll make sure everything is up to dat and report.

Voldenuit.
It was a feat of Cat5 and power supply cable stretching to get my Mac going directly into the Modem. Unfortuantely, I can't run it directly.

You should disconnect all non-Apple peripherals (like the above) while troubleshooting. Some printers have atrocious software that has been reported to interfere with OS X in several different circumstances.

Hi did you ever sort it?... I get this coming up when Chronosync is running... I think. If you know what it is let me know too. thanks
