Hi together,

finally, after a lot of attempts i were able to install Leopard and it seems to run smooth except two problems.

Programs like Mozilla Firefox, Transmission and some others seem to crash pretty often. Either without a error message or with a message, it depends. It starts to get a little annoying since i need to get some important work done. Here's the console report:

21.02.08 10:23:30 com.apple.coreservicesd[53] 2008-02-21 10:23:30.399 SFLConvertGlobalLoginItemsTool[127:10b] _CFGetHostUUIDString: unable to determine UUID for host. Error: 35

21.02.08 10:27:30 Console[153] _CFGetHostUUIDString: unable to determine UUID for host. Error: 35

Mozilla crashed because of a floating point exception, whatever that is o.O By the way, what do all those "unable to determine UUID for host" things mean? Could this be a reason for all the crashes?

Next thing that is bugging me is that the system seem to slow down after a while. I noticed it the first time after i worked a few hours (around 5) with a fresh installation of Leopard. Programs started to crash, the computer itself acted slow as my grandma and most important, the mouse jumped around (from one corner to the other). Annoying if you set a few hot corners ^^

So i would love to get a little help here. I'm still new to all the Hackintosh stuff, nontheless i'd like to have it run smooth =)

Thanks in advance,
Tom

I've been posting this as many places as I can, I think the problem is a memory timing issue, as I have slowed mine down and havent had a program crash since. Also if I speed up memory my mouse becomes very twitchy and jumps across the desktop with a small movement.

Try to add this in /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist below the last </dict>

And reboot.

Hey,

@lanxxx
I know, i am TomH at insanelymac so we've already talked about this ;) Problem is, my mainboard doesn't have an option to alter the memory timings. Is there a workaround?

@zephy
I'll give it a try and let you know what happens. Thanks so far and thank you for the release. Beside the problems it's the first release that runs with my specs. *thumbs up*

Well, i added it and the first thing i've noticed is that my internet connection seem to be twice as fast as before. Don't know if it's just a presumption.

Now i have to wait and work a few hours until i know if it helped to solve the crash problems or not. Like i said, mostly it happens after a few hours.
By the way, the UUID error is still there.

21.02.08 11:19:04 firefox-bin[140] _CFGetHostUUIDString: unable to determine UUID for host. Error: 35
21.02.08 11:19:39 quicklookd[143] _CFGetHostUUIDString: unable to determine UUID for host. Error: 35
21.02.08 11:19:44 Console[145] _CFGetHostUUIDString: unable to determine UUID for host. Error: 35

=) Thanks so far!

Ahm ... this might sound stupid now but the file i extract from the zip-package, is it really a .kext file? I only see IONetworking without a extension. I did the following steps:

- Extract the file from the .zip-Folder
- Renamed it to IONetworkingFamily.kext
- Deleted the original File from /System/Library/Extensions
- Copied the new, renamed file into the Extensions folder
- Did the sudo stuff
- Restarted and my internet were gone. A error message popped up that the .kext could not be loaded
- Copied the backup of the original kext back to the Extensions folder, did the sudo stuff, restarted and my internet is back

I am sure i did something wrong, maybe the renaming of the file. One thing i've noticed is that if i rename the file, i can't get "inside". With other kexts it is possible.

So what did i do wrong? Sorry ... noob alarm ^

lol damn I made a mistake !

You must replace /System/Library/Extensions/IONetworkingFamily.kext/Contents/MacOS/IONetworkingFamily with the one you extracted !

Sorry !

lol ... happens =) Well, will try that in a bit

//edit
I guess that solved the problem. No more UUID errors ... at least for now. I keep watching the console from time to time and let you know what happens. Thanks zephy, good job as always ;)

hi all...

I have a thinkpad X300 and I am getting floating point exceptions all of them time, which mainly cause crashes for Internet based applications such as Firefox and Safari.

What was the end solution to this? Was it memory timing? I'm using a laptop, this is nothing I can really control.

Here are the kexts I have loaded. I am using 10.6:
