Jaguar is great. Best thing I've seen is smoother and faster scrolling. But one thing that really bugs me is that when the computer is sitting idle, the Finder is taking up 95% of my CPU.

At this rate, my CPU will fry from just having my computer on.

Hope that's a bug they fixed in later builds.

What is the world coming to when a file manager can eat up all the power of a 'supercomputer' that was almost banned from being exported to Iraq.

I don't think the 10.2 build I have (WWDC) ate up 95% of the CPU. At any rate, the system was extremely responsive, so if it was eating up 95%, then it was doing it in a very well-mannered way.

However, it's pretty silly to worry about this now, since obviously whatever build you're using isn't the final release.

as for the topic, can you really imagine them shipping an OS that takes up 95% of the CPU when sitting idle? doesn't make very good business sense to me, when you're trying to gain new users all the time. as someone else in this thread said: it's unfinished work.

you're not even supposed to have it, so don't moan about it

Sounds like a memory leak in the finder... Is it using 95% from the second you start up the computer? I'm not a betting man, but I would guess that it won't make it into the final release...

10.2 is betaware... and memory leaks happen. 9.1 had a little one for the longest time. there are so many features being added 10.2 that I'll be amazed if we don't get the $50-$100 upgrade tax. Then the real trolls will be out in full force... like me ;-)

I had a similar experience using the WWDC developers' preview - In one session I had the finder consuming ~80% of CPU. Only saw it once.

I should imagine that it was something that will be fixed by final release.

Unless the computer is in sleep mode, something will be using 100% of the CPU. Just check out the "System Idle Process" under Windows NT/2K - it usually sits at about 90% of the CPU when the system is relatively lifeless. If Finder is using all spare cycles that sounds more like efficiency than a problem - especially if there is no disk trashing or other obvious signs of a poorly behaved process. The problem isn't how many cycles an app uses when no one else cares, the problem is how many cycles they use when other processes are starving. And, as you mentioned, if it isn't trashing memory or your disk then it is probably harmless.

BTW, I don't think memory leaks would cause this behavior. If it did have a leak and it was that serious, the VM would be thrashing like crazy and the system would become unusable eventually.

Also, if you were complaining to us and not to Apple, it clearly would NOT be fixed, as Apple may know absolutely nothing about it, and thus, you are hurting the future of OS X.

If you don't have a legit copy and you are complaining to us about it... well, I think I'll just stop.

What do you expect out of an alpha version? It has bugs. Lots of them. Deal with it. Run 10.1.5.

Nobody's CPU ever fried from running at 95% 24/7 unless it was overclocked.

I can verify, with the help of 6 QuickTime movies and an electronic thermometer, that this is not the case. When the idle_thread is at 90%, your CPU is only 10% in use.

If your system was leaking memory fast enough to cause your CPU to hit 95%, your hard drive would be at 100%. Your system would most likely become unusable immediately.

Well, I just hope it's not a feature. The CPU load obviously adjusts itself when other apps are running, etc. If it's a bug, i guess they'll fix it. If it's supposed to be like that, then I'm not so sure it's a great idea. Overall, things multitasked well, but I noticed a considerable slow down in IE 5.2.

Oh, and not to mention that IE 5.2 using the carbon Quartz engine has some serious bugs. OmniWeb ran fine, but IE 5.2 left a lot of garbage in the window when I was scrolling up and down.

Don't know if the build I was using had Quartz extreme, but I sure didn't feel it when resizing windows. Although I did feel it when scrolling.

BTW, iChat was interesting...

I'm surprised that KH isn't aware of this, but the black helicopters that fly over his house can and do mess with his computer. It's a fact. I read it on some web page once.

And here he's been blaming Apple for all his problems!

Strange... I rebooted into Jaguar, and the Finder usage of the CPU is fine. I'm not getting that 95% usage anymore. It must have been a bug or something that caused the finder to use a lot of resource. Strange. Again strange... Finder quit unexpectedly and rebooted and now the dock shows it's not running at all when it is... Guess it'll be fixed. All the while iTunes kept playing fine. Guess that's a good sign.

I had a problem in 10.1.4 where every *other* reboot would cause the kernel_tasker to use all CPU. A reboot would fix it. I don't see this problem anymore.

First of all, it's a beta, so don't expect anything from it. It's more or less a technology preview.

From what I have seen (Jaguar Server), it's speedy. I am anxiously awaiting the final release.
I don't suffer from insanity, I enjoy every minute of it.
