If this is the case, and they weren't, you need to file a bug report. Otherwise, you can get around the default limits by doing the tweaking I suggested, but I'm not going to give a "cookbook" for this, since it would be inappropriate for iBooks with 128M of memory, and I know people would probably tweak things anyway, if they had a cookbook for it, and their machines would start to fall over under load, rather than simply load shedding. having said that, understand those defaults may very well be reasonable and acceptable for the average user. Correct. The average Macintosh user is not going to be able to tweak things the way a UNIX admin would tweak them, i.e. remove all constraints, load the system to failure, and then back the administrative limits down to just below the peak at which failure occurs to balance load capacity vs. failure point, and thus maximize their capacity. Meanwhile, normal Mac users tend to have a really mixed general purpose computing load, unlike servers, which tend to be dedicated to a single function -- so it's nearly impossible to predictively arrive at what administrative limits are reasonable, if all you have is the hardware specs and no idea of the machine's intended role. About the best you can do is pick administrative limits that don't constrain 99% of the typical uses for the machine, but protect it from failing, and tell the remaining 1% that they need to do additional administrative tweaking for their out of the box use cases.

ANN: SEDarwin Release
by Todd Miller 06 Nov '06

06 Nov '06

site_archiver(a)lists.apple.com Delivered-To: darwin-kernel(a)lists.apple.com The first widespread release of SEDarwin is now available for download at http://sedarwin.org/ SEDarwin is a port of the TrustedBSD Mandatory Access Control Framework to Apple's Darwin operating system platform, along with a Type Enforcement policy based on SELinux. SEDarwin is still experimental, but currently allows the enforcement of mandatory process and file protections under Darwin 8.7 (Mac OS X 10.4.7) on Apple PowerPC hardware. The October 31 snapshot includes the most recent SELinux kernel and user space components available. We are still working to adapt the Treysys reference policy for Apple's System, but the kernel and user space components are largely complete.

Now i've seen stuff all over about compiling against the 10.4.0 sdk and I am. I'm using Mac OS X 10.4.8 on PPC with Xcode 2.4. I know it's an incompatibility betweeen the IOAudioEngine in the headers and the IOAudioEngine in the running kernel. Problem is, I have no clue how to reconcile the issue. *ANY* guidance, docs, or anything that someone can offer would be of immense help. Have you checked out this technote?: <http://developer.apple.com/technotes/tn2006/tn2163.html> Hope this helps. {P^/ _______________________________________________ Do not post admin requests to the list.
