Workaround for 10.4.10 Firewire Audio device problems
Although Egil had written Monday night that the Apple Audio Update 2007-001 had solved the problem he had with a FW Audio interface in 10.4.10, he later wrote it was not actually the fix. (The Audio update has no FW audio driver update included.) Here's the workaround he had used successfully - reinstalling the 10.4.9 Firewire audio driver into 10.4.10:

"...If Rick is of the adventurous type, he could try doing the following:
- Download Pacifist ( and open the program
- Download the 10.4.9 combo update
- Drop the 10.4.9 combo update package onto Pacifist
- Search for AppleFWAudio.kext
- Select it and choose install
Then, after reboot, see if that makes any difference. That will bring the audio component back to 10.4.9 state, which as I mentioned also worked for me. But as you pointed out, your mileage may vary here as well...
Cheers, Egil"

    Latest info on 4GB RAM in Core2 Duo MacBook (w/Benchmarks)
    (from a recent reader mail - updated 1:45PM with more info)

    "Hi Mike, I just upgraded my (Core2 Duo) MacBook (NOT Pro) with 4GB of RAM. Normally the MacBook is only able to work with 2GB (what Apple says) but some people found out you could also use 3 GB (1x 1GB 1x 2GB) or even 2x 2GB of RAM but the MacBook would only recognize 3 GB. Thats what I wanted to do... and now look (screenshot showing 4GB recognized in Apple System Profiler memory section and "About" info.)
    My MacBook uses all my RAM! As far as I know only the SantaRosa Boards are able to work with 4GB of RAM. Or did I miss something???

    I asked Alexander if 4GB total was also shown in Activity Monitor and if he'd seen any issues with deep sleep, etc. (In case some 2x2GB pairs may draw more power than Apple designed for.)

    "Here a couple of answers that might be of interest: Activity Monitor actually only shows 3GB of RAM being in use. MenuMeters shows the same.
    Rember (Memory test tool) sees all 4 GB but can only adress 3GB.
    Now the strange thing: Parallels can adress 3.47GB of RAM!

    DeepSleep works as expected. I tried it with the DeepSleep widget and with battery running out. The only thing that hurts is, that the DeepSleep Image that is used to store the RAM on the HD eats up 4GB now... The total running time actually seems to last a little longer than with 2GB. But only like 10-20min or so, but still a gain... (I guess having more RAM saves some HD access, as 4GB of ram uses more power than 2GB)
    As I mentioned before SystemProfiler reports that there are 2x2GB Dimms in the machine but OS X only seems to use 3 of it - bummer.

    The good thing is that by using 2x2GB dimms, the chipset can use the interleaving mode... its a bit faster than using 1GB and 1x2GB dimms.

    Everything is running fine and Rember as well as the AppleHardwareTest show absolutely no problem working with the dimms. I tried to find something out about the Chipset Intel 650 and it can only adress 3.3GB of RAM. Apple seems to restrict this in EFI to 3GB, don't know why. The only thing I can think of is that Apple wants to keep a distance between MacBook and MacBookPro.

    Conclusion... I can confirm the 2x2GB dimms are working fine and they should work faster than a 1x1GB + 1x2GB configuration although I can not show this in benchmarks. All I can say is that the machine is fast. VERY fast.

    There was some discussion on this in the news page here back on May 25th, despite Apple's note that 2GB (2x1GB) is the max supported, OWC has a page of Macbook memory benchmarks with apps/benchmark/game tests of various amounts of RAM up to 4GB with a C2D Macbook. (Original Core Duo MacBook tested up to 2GB.)
