    ichat multi conferencing

    I've done a 3-way conference on a local wireless network (802.11G) between 2 Macbooks and a 24" iMac, and it worked flawlessly. I'd suggest opening up Activity Monitor on all three machines during the conference call, and see if any of them are pegging either the CPU or the network really hard. Gigabit is way more than enough, so it sounds like something weird is going on.

    Rejected Password in Mail

    I see this sometimes, and thus far I've blamed it on problems with the ISP. I think that this is the behaviour you see if there's an error connecting to the POP server. Of course, Mail.app *should* really give a better error. When it happens, I usually just hit "Cancel", and try again later.
  3. Anyone know why Garageband only ever uses one of the processors in the Intel machines? My musician friend just got a Mac Mini to play around with Garageband, and after adding a ton of tracks and effects, he gets the dreaded error message from Garageband saying too much was going on. So we try the song again, but this time I run ActivityMonitor at the same time. What a surprise I got when I saw that only one of the processors was being pegged for Garageband, despite 18 threads running. Am I missing something here? I've never programmed against Cocoa before, but I would assume that if you had multiple threads, the OS would spread them out over the multiple processors. It seems that Garageband is putting ALL of the audio processing into just one thread. Either that, or I have no understanding of how threads run on OS X (which is just as likely). Jay P.

    Make Garageband use both processors

    Ok, here are my latest results: Doing a Command-Y to hide the meters chops a few points off the CPU requirements. Locking tracks makes a HUGE difference. I created a song with about 20 tracks, and it would only play about two seconds of it before giving up. If I lock all the tracks, CPU usage drops to almost nothing (Activity Monitor shows Garageband at 30%). Here's the really interesting thing: When I do it without locking the tracks, and Garageband stops playing it, it *is* in fact spreading the load over both processors (according to the "CPU Usage" graph), but it refuses to use more than about 50% of each processor. As soon as the process gets to about 80% CPU, it cuts out. So *maybe* there's something in Garageband that makes the song stop if the song hits a certain percentage. Of course, when it cuts out, there's still a ton of CPU available (because a process at 80% CPU means using each CPU at 40% each). So, yeah, that's about it. Locking the track works great, and I was technically wrong about it not spreading the load. It does spread the load, but refuses to put too much load on it.

    Make Garageband use both processors

    Like I said earlier, there were over 400 megs free, it's a processor thing. I'll give that a try. Of course, even if I free up more of the processor, it'll still bug me that his Garageband is still ignoring the other one

    Make Garageband use both processors

    That's exactly what I thought too. However, I'm beginning to believe that's not the case. If you look at Activity Monitor, pretty much every app is running with multiple threads, I believe that Cocoa pretty much demands it. However, it doesn't really look like *any* app I run ever spawns across both processors. Maybe Apple forced Garageband to stay on one processor, to give people reason to upgrade to Logic?

    I checked the RAM usage as well, he had tons free (at least 400 megs). The one processor core was completely pegged though, which is why I'd love for it to use both.

    ssh seg faulting after security update

    Just wanted to post again, saying I fixed the problem, by using this link: http://discussions.apple.com/thread.jspa?m...07 Namely, the part where they talk about Kerberos. Jay P.
  9. I just ran Software Update, which did the X11 update (been holding off on that one), the latest security update, and the Airport Extreme update, on my Intel iMac. Well, now whenever I try to run ssh from the Terminal, it segfaults on me! Anyone else seeing this? Jay P.

    CAD software suggestion?

    Google Sketchup is pretty great, but this program (mentioned by Adam during the Macworld coverage) looks pretty cool: http://www.belightsoft.com/products/livein...or/overview.php Jay P.

    Nintendo Wii

    If you buy Nintendo's USB WiFi adapter, you do need Windows. If you already have a wireless router though, you should be fine. My network has two Macs, one Linux machine, a Wii and a DS on it, no Windows in sight. Jay P.
  12. Very weird problem here. I've got a new 20" iMac (well, I've had it for a little bit), and for the first time today I decided to run "Keychain Access". I use that program a lot on my old Powerbook (running Panther) to store my passwords, so I wanted to see how the program looks under Tiger. Well, everytime I start it, I see the application window appear, and then it crashes one second later. Without fail. This is scary, obviously, because Keychain Access is pretty important. I did however find a workaround. If I open up the Info dialog for the Keychain Access app, and tell it to run the program using Rosetta, then everything works, fine and dandy like sour candy! I've run Repair Permissions on the disk. I've run the Keychain First Aid (using Rosetta). Still, the Keychain Access app crashes if I try to run it normally. Has anyone seen anything like this before? Any ideas? Oh, and the crash report is very unhelpful. It of course has gobs of stuff in it, but the key lines (in this programmer's opinion) are: Exception: EXC_BAD_ACCESS (0x0001) Codes: KERN_INVALID_ADDRESS (0x0001) at 0xb1e06f60 That's some bad mojo right there! Thanks, Jay P.

    How long to encode a DVD?

    My friend recently brought over 15 minutes of MiniDV footage (not a lot, I know). We edited it in iMovie, and burned it with iDVD. The iDVD encode process took about 30 minutes, but it seemed (IIRC) that most of that time was spent doing the animated menus, of which we had a few! The audio processing especially seems to take awhile to do. We originally had a 6 minute song looping on one of the menus, we chopped that down to a 30 second loop because the encode was taking forever. This is on a 2.16 GHz Core 2 Duo iMac with 2 gigs of RAM. Jay P.

    Keychain Access crashes on Intel Mac

    Oh, and one more piece of info. In the second before it crashes, I can see all three of the Keychains are there (login, System and X509Anchors), but none of the items in the login keychain are showing up in the main part of the window. This leads me to believe that it's crashing while reading my login keychain. But it's strange that it would crash when running x86 code, and not PPC code, unless they screwed up some endianness issues. I'd imagine though that would have been caught a long time ago, were it the case. Jay P.
