Actually leaving lots of programs open all day will cause potential decrease in performance because THEN they will have to be paged out if you load some memory intensive program. Inactive memory isn't paged out if the program is closed or quit when you launch some memory intensive program...

Hehehe. You're a programmer jzdziarski? I'm not sure what's prompting you to act like an asshole in a public forum, but if you can't be constructive, I suggest you find another forum to post in. Make a call to malloc() for whatever size buffer you want and tell me if it's zero'ed out. It...

Yes, being a software developer I think I understand it. Funny how if I reboot before playing, everything runs smooth. On the other hand, if I kill everything after a day of work (including the dashboard), and play, it's jerky. I didn't have this problem in panther.

yeah I tried that. After logging into the ADC, I tried to use the bug reporting tool. I was told I didn't have permission to access that application. Someone gave me this url,however... http://www.apple.com/support/security/

And the overhead of clearing another gig of pages while in the middle of a 3D first person shooter is enough to kill your frame rate.

Here's the thing. If I want to keep apps resident in memory, I'll leave them open. That's one of the beautiful things about OSX is that you can have something like Safari open without actually using it. Adding the overhead of all this post-release memory management is just another annoying...

Apparently the algorithm needs work. For example, I spend about an hour playing UT2K4 around 6pm or so. I play it exactly once a day, yet OSX keeps all 700MB or so of memory used on the inactive list, when it should be flushed. It also should have flushed out all the programs I don't use after...

Here's a workaround suggested by someone on the full disclosure list. Remove the sudo grace period by adding: Defaults:ALL timestamp_timeout=0 To /etc/sudoers. Why this was not made the default I don't know.

It appears that if you authenticate anywhere on the system using sudo, the Widget can take advantage of it. This, of course, opens the door for worms, hackers, drones, spyware, and anything else you can think of - whether the widget was auto-installed or not. Don't feel bad Satcomer, you're...

1. Having things in inactive memory is to your advantage. OS X is predicting that your next request for instructions is likely to come from certain recently accessed instructions. There is no problem in having a low amount of free memory in OS X. OS X has stored many instructions in RAM (in its...

*nixes = UNIX operating systems. Linux, FreeBSD, Solaris, etc.

I looked around and didn't see any invitation from Apple to report vulnerabilities, so for now I guess I'll post here and leave it to someone with a paid developer's account to tell them. Date: May 19, 2005 Description: OSX 10.4 Dashboard Permits Hijacking of Authenticated Credentials...

I'm somewhat unfamiliar with how OSX deals with memory. In most *nixes, when an application exits, the entire process image (including all allocated memory) are unlinked completely and returned back to the operating system. I've noticed OSX seems to act more like windows, however, and when you...

I noticed some of Apple's own scripts don't work. For example, "Get Source of Selected Message.scpt" This line doesn't appear to be evaling to true when there are messages selected: on perform mail action with messages theSelectedMessages Anyone running into similar scripting issues?

One thing you might want to check is if you have any old kernel drivers or such installed. I found, for example, after ripping out VirtualPC and its drivers that Tiger ran much smoother whereas before it was running very slow (even if I wasn't running VirtualPC). I suspect this may have to do...

I have 2 x 512MB PC2700 memory modules that came out of my nearly new Powerbook G4 (I upgraded to 2GB of RAM). I'll sell both for $130 or individually for $70 (PayPal). One is the factory Apple memory and the other was purchased from We Love Macs. Email me at jonathan@nuclearelephant.com if...

I'm not sure why everyone's so scared about this whole widget auto-install problem. It's not as if it's very hard to disable; just uncheck "Open Safe Files after Downloading" in Safari's preferences, and it won't attempt to install the Widget. Is this not public knowledge?

Run the activity monitor (or top) and see what's taking up so much CPU. Check your preferences and make sure that your processor performance is set to 'Highest' and not 'Automatic' (Yes, highest provides much more power in all the benchmarks I've seen). You can use iostat to see if it's disk...

I suspect it depends on the program. In a gaming environment, it's not likely to page out the entire 200-300MB of inactive memory at once. If it only needs 10-20 MB, it will page that out, then page out some more when it needs it. This usually causes the game to stutter quite a bit.

I'm curious if anyone's come up with a good approach to shutting down all noncritical services (quickly) to start up a rather large game (such as UT 2k4). Rebooting will only get you so far. I'd like to be able to: - Flush all inactive memory - Shut down all noncritical services, such as...
