" CCC 1.3.1 is NOT compatible with Mac OS 10.2. There are fundamental changes to Mac OS 10.2 that are not accounted for in version 1.3.1 (and earlier) and any attempts to clone will yield an improper clone. Please use CCC 1.4 with Mac OS 10.2. Version 1.4 can, however, clone a volume that has any version of the Mac OS installed.

Also, CCC 1.4 only runs on Mac OS 10.2 and above (again, though, v. 1.4 can clone older systems, just not while booted from the older systems). This was not an easy decision, but I don't think I've left 10.1.x users in the cold; v. 1.3.1 is really quite good, and as good as it could get given the OS limitations. Committing to 10.2 exclusively meant that I could drop a lot of hack code that existed to workaround problems solved many OS versions ago. I was able to reduce the amount of code used by about 15% and offer some really nice optimizations resulting in a faster and sturdier application. If you would like to clone your 10.1.5 system before upgrading to Jaguar, use CCC version 1.3.1 instead. "

BTW - I seem to get the following repair note every time if the system has been restarted.

" Group differs on ./private/var/run/utmp, should be 0, group is 1 Owner and group corrected on ./private/var/run/utmp Permissions corrected on ./private/var/run/utmp "

Searching google for info on utmp finds this page (among others) which says "The utmp database file contains user access and accounting information for commands such as who(1), write(1), and login(1). The wtmp file contains the history of user access and accounting information for the utmp database." and under Usage says "The utmp and wtmp files are obsolete. They have been replaced by the extended database contained in the utmpx and wtmpx files. See utmpx(4)". (Doesn't apply to OS X apparently, which must only use utmp. It's odd that after every restart the file permissions are not correct per the permissions utility check.)

" Mike,
Regarding the support of Catalyst with the Sonnet G4-800, there is a long discussion on MacGurus about this subject, that finally hit upon the truth:
There is indeed some Sonnet "voodoo magic" that I designed into the card to support the missing signal, DRTRY. I had to overcome a huge number of technical hurtles with the product, and we thought, if we're doing all this other stuff, like taking on the six PCI slot problem, perhaps we can support the Catalyst based Power Computing machines as well. The problem is solved in a very clever way.

The installation instructions for this product are slightly different than for the Powersurge platforms, so your readers with these machines should carefully follow the installation procedure.

It works great though, and we even support OS X on these machines with our "PCI X install" product.
Thanks,
Henry

"Hey Mike,
I thought this pretty worthy of passing on. For those planning on going the OS X route with the Crescendo G4/800, keep in mind that if you have an ATA PCI card installed, the infamous audio stuttering is more than likely going to rear its ugly head -- even if you have never had problems in the past. (This issue is noted in the past here on the IDE articles page, FAQ, etc. - more common in the early days of IDE cards, but less common in the last year or so. And there are OS 8/9 AV utils to address the issue for most cards now, at the expense of performance typically. But I've seen no OS X version of the A/V utils to address this as of yet. Note that audio played back from the onboard SCSI or onboard IDE connected drives usually never have the problem.-Mike)

In the case of the various Sonnet Tempo cards, there's currently no AV optimizer tool available like there is for OS 9. Sonnet's support department has told me they're gathering information on whether they should allocate the resources to address this, but so far only a few people have contacted them, leading them to assume "demand just isn't there."

In my case, I was totally blindsided by this. I have a 9600/350 and Tempo 66. I've NEVER had audio stuttering, even after upgrading to a Crescendo G4/450. I've been running OS 9.1, OS X 10.1.5, and OS X 10.2. But as soon as I plugged in the G4/800 the problem arose. Sonnet says I apparently "upset the Apple cart."

Otherwise the G4/800 is pretty incredible. I intend to post a thorough review in your database soon.
Thanks for the great site!
Troy"

I assume this is not the (common) audio stuttering heard in iTunes during heavy network access/downloading from the net, etc. (I and others have noted that issue here in the past several times with OS X 10.0-10.1.x at least, even on modern macs and onboard IDE. 10.2 seems better about that so far here.)
Even though he noted it didn't happen with a previous (G4/450) G4 upgrade card, I asked if he had tried moving the IDE card, etc. to another PCI bus of his 6 PCI slot mac. Since he noted it occurred only with the G4/800 card, that may not matter however. (Update - see below for his email reply - he noted moving the Radeon PCI card to an upper slot helped.)
I don't have a Sonnet card personally so I don't know how common this is, but for those Sonnet G4/800 CPU card owners using an IDE card connected source drive, let me know if you have seen this problem in OS 9 or OS X. Include as much detail on your system, IDE card (model, firmware, etc.), drives used, etc. as possible.
It may not matter, but I'd also like to know if your ram is interleaved (matching dimm sizes in Ax/Bx slots for macs that support interleaved ram.)
Update: Troy replied with more info and a fix for the problem:

" Mike,
Since my last e-mail, I've discovered all sorts of interesting little nuances about the Crescendo G4/800. I also think I've finally pinpointed the cause of the audio stuttering/dropouts. To clarify, the dropouts only occurred when playing a QuickTime movie.

First off, the QuickTime audio problem disappears entirely by moving the ATI Radeon 7000 into one of the top three slots. This isn't a huge deal to me, because it appears Sonnet has indeed addressed the six slot issue for the most part. I haven't done much testing yet with my FireWire and USB cards, but I can confirm they do work in the bottom three slots (at least for things like scanning and printing). The one thing I do worry about is how warm the underside of the Radeon gets, so I'm going to leave the PCI slot directly below it empty.

To address some of your questions: 1) RAM is interleaved. I've never had any problems either way, in 9.x, 10.1, and now 10.2. De-interleaving did not cure the stutter. 2) Yes, the stuttering occurred in OS 9, but it was more like little audio pops. Acard's AV Optimizer didn't stop it, which is one of the reasons I decided to start looking elsewhere. 3) I've never experienced the iTunes/network problem (audio dropouts in OS X when playing itunes songs and downloading files from the net at least with high speed connections) - very common as noted by me and many others in the last year even on modern macs. seems fixed in 10.2.x so far at least.-Mike) , and I listen to MP3s all day while I'm working. 4) If you move the Tempo 66 into one of the lower three slots, you can't boot up from it (at least I couldn't).

One last point which may be of interest to some: In my 9600, I could not install any flavor of OS X on a drive connected to the internal SCSI bus with the G4/800 present. (This was using both Sonnet's installer and XPostFacto.) If I switched over to the external bus, I could get it installed and booted, but if I switched back to the internal I was hosed. This DOES NOT happen with the G4/450 or any other upgrade I've tested.

Now, a word about general performance: This card absolutely flies. In OS X 10.2, it feels at least as responsive as an 800MHz iMac, if not a bit moreso. I'm incredibly impressed so far, and will post a full review after I've done some tests editing video and such. (BTW, if you have some established tests you'd like performed, let me know and I'll do my best to pass them on.)
Thanks again for all the valuable resources!
Troy"

" Mike,
I recently posted a review of my upgrade (Beige G3 DT with OWC G4/450 report in the database here) and cited problems with Logic Audio. Well, by the suggestions of users in the Yahoo Logic Users Group I turned off the "Use Velocity Engine" setting within Logic and got rid of the pops and clicks. It's still very fast and I'm able to do much more with my upgrade. But I suppose if someone wants to upgrade their processor for use with Logic Audio I'd recomend sticking with a faster G3 rather than G4, especially if they don't plan on using much of OS X like myself.
Thanks for your very helpful site.
Dennis "

I seem to remember at least one other report like this before, but I'm not sure it's typical with all G4 upgraded Macs/OS versions. If any G4 Upgraded B&W G3, Beige G3 or older Mac owner (not G4 Yikes or later) is running Logic Audio can comment (tip/suggestion/seen the same thing or not) let me know.

" Mike:
Just wanted to see if you could gather a bit of info from your readers regarding the use of the new Sonnet G4 800s (PCI) in the PowerComputing PowerTower which, according to Sonnet, isn't fully compatible though they have it listed in there install pdf (haven't heard back from them yet, though I might assume it just can't support altivec thereby making it a g3 800 in effect.) Even OWC has it listed under PowerTower upgrades. The 60mhz bus is the only reason I would even consider it and oddly enough this is one of few models that has it.

I realize you're probably as busy as a one armed paper hanger and I rely heavily on your site for great info, but any help would be appreciated because I was hoping to get some more use out of my PT 180e which now has a PowerLogix G3 375 running at 420/210 and I'm sure there are others like myself w/ just plain PowerTowers...... Thanks.
Sincerely,
Matt J"

I written my Sonnet contact to ask for clarification/info, but I replied to Matt that I was surprised to see a Catalyst based motherboard model included on Sonnet's product page list (I.E. PowerCenter and PowerTower- still listed there today with an *) - past G4s (7400/7410s) would not work in them. As noted here before - the Catalyst based motherboards reportedly have a missing signal that the G4 needed on the motherboard. (At least the G4/7400-7410 models - I don't know about the 745x G4s since Sonnet has the only 7455 G4 CPU upgrade card to date for older Macs.)
There's a few Sonnet G4/800 reports in the database (PowerTower Pro (Tsunami based mb), 7500, PowerWave, 85/8600 owner reports) but I'd welcome more reports - esp. from Catalyst motherboard based mac owners. (Post an entry in the database - entry page linked on the search page.)

About the Bus Speed: Realize that Sonnet cards are not adjustable (for bus speed or bus/cpu ratio) - the Sonnet G4/800 card runs at 50MHz bus speed x16 ratio (for 800mhz CPU speed). The CPU card in older Macs always controls the bus speed, so unless you made mods to the Sonnet card, it would only run at its default 50mhz bus speed. And if the bus speed was boosted (by modifications), if the cpu ratio is not changed (modified to lower it), a 60MHz bus speed would be overclocking the CPU by 160MHz. (10MHz higher bus speed times 16x ratio.)
The japanese page on overclocking the Sonnet G4/800 card noted here in Wednesday's news said the 60Mhz mod (960MHz CPU speed) ran for them in a Umax machine, but it may not for other systems or card samples. (And would void the Sonnet warranty, and could have short or long term issues at that high an overclock.)

" The software is not officially released yet and still has a 'time out' function in certain features. It will be released next week. "

Officially they are not recommending this version be installed. I asked if the final 5.2 update would install over the 'gm' version and was told yes. If you've not already installd it, it's best to wait for the final/official 5.2 update due Oct. 2nd. (Again Although not everyone had problems (about 1/2 dozen readers noted 5.2 gm worked ok), several readers reported crashes using the updater linked earlier today. But they also noted that the previous version left intact (as is typical with recent Toast 5 updates) ran ok.

" Just an update, I maxed it out with dnet for the last 20 or so hours straight. Looks like a keeper. No problems at all. What a nice surprise.
Lin P.

(his original comments from yesterday's news follow for those that missed it)

...I previously owned a QS867 that I attempted to OC and it was very flaky. I kept losing the L3 cache like everyone else did, so after a few hours I determined I wasn't in for a voltage tweak, so it remained an 867.

But, I recently purchased a new Dual 867, that after a couple days of fooling around with I decided to take a shot at overclocking it to 1GHz and see if any progress had been made. I dabbed some defroster repair paint on a couple places, restarted and lo and behold Dual 1GHz running reliably (so far 4-5 hours later).

During normal usage the fan stays somewhere between the lowest setting and the middle setting. It moves up and down fairly often. With dnet on it will move into the high sped setting every now and again. I'll leave dnet on for a few hours and see how it behaves.

Anyhow, thought I'd let you know that either I'm very lucky or the new models have a little more headroom than the older ones.
