Freezes when idle

I've been having an issue since installing Leopard. When I leave it idle, it will freeze. Sometimes, the mouse will bring the display out of sleep but it will be frozen; other times, the display won't even wake up. It's never happened while I have been on the computer but it's happened every single time I've left it for several hours unattended. Everything else works fine (except Logic Node crashes at startup).

I installed Leopard as an archive and install so there shouldn't be any issues with improperly upgraded files. Should I try booting up in safe mode and see what happens? Anyone haven any suggestions? I don't exactly want to put it to sleep every time I'm gone for any length of time.

Octa-core Mac Pro, Mac OS X (10.5), 250+500GB hd, 3GB ram, AE, BT

I have been having the same problem, but also a bit worse.

If I leave it for 30 minutes orso on sleep, I cannot get it out of standby mode. Not even with the mouse, closing and reopening the lid or whatever.

Also, since Leopard, my Macbook freezes VERY frequently (up to 3 times a day) with a kernel panic message, and every time Leopard says that the kernel was trying to clear memory while memory was already cleared or something. Next time it freezes I will post it here.

I am not doing anything special with my Mac, just surfing the web with safari, listening to music on iTunes or watching a movie with Front Row. Then suddenly internet kicks out and then a kernel Screen of Death.

It's getting really annoying, and, more frequent.

Same problem here...I thought could be the memory upgrade...because it was the only thing really changed (I've taken a 40$ 2gigs memory upgrade in two blocks...maybe defective 😉 ?)
but if you say that I'm not the only one, it's definitely a software issue.
I had tha same issue as in an "upgrade" install, as in a "from scratches" install...more or less frequently...

I can't help you either, but I thought I'd chime in and say that this happens to me on a regular basis too. I thought it was because I have an external monitor installed. I sleep my Macbook, try to wake it up, and it doesn't quite go all the way. I can hear the usual hardware sounds that tell me it's waking up, but the external monitor won't kick in, and the built in display is black.

I am also having similar freezing issues. I have an iMac G5 2.0ghz machine.

My problem is that the system completely freezes up, so I have to turn off the computer using the power button.

Upon restart, the computer will just sit at the grey screen with the Apple logo and hang. The fans cycle at full tilt, but nothing.

I have now performed an erase and install 3 times, and I'm very upset with this upgrade. I have wasted the last two weekends on this garbage.

Apple phone support suggested it might be a USB peripheral that I had attached, so I've tried unhooking everything.

I have no weird apps installed, and only use the computer lightly for mostly internet stuff... Mail and Safari, and a bit of iPhoto and iTunes.

I am convinced my problems are not unique, and this should have been picked up in beta testing!

Well I spent all of yesterday in safe mode with no issues. While I was there, I removed Logic Node from my startup items (since upgrading to Leopard, it always force quits right at startup). I don't think that has anything to do with it but I also upgraded my EyeTV software to the latest version. I restarted back in normal mode and let it sit overnight and it didn't freeze. Maybe it was something to do with EyeTV.

Today has been the worst yet. As I said earlier, it froze when listening to iTunes this morning and froze while I was away for a few hours in the middle of the day. Since then, it froze when I was watching EyeTV this afternoon, when I was taking a shower, and again while listening to iTunes tonight. The last time it it happened, I had already unplugged my EyeTV tuner, M-Audio MIDI interface, and my external FW hard drive. I'm now back in safe mode and hopefully it holds until the next update.

I've experienced a similar problem, since upgrading to Leopard. I bought a new MacBook Pro about 10 days ago, and transferred my 10.4 install; it worked flawlessly. After installing Leopard, I'm encountering these odd freezes (after going to sleep, it starts to "wake up" but then stops... I usually get it to complete the wakeup after opening/closing a few times, and pressing on/off button... at which point I get a message asking if I really want to shut down, sleep, etc.

This problem is accompanied sometimes by a jumpy mouse. Occasionally the problem goes away after a few minutes, but at other times I have to reboot. This is not the Apple brand experience I'm used to. Can anyone from Apple weigh in on this?
