chapolote Posted June 6, 2013 Share Posted June 6, 2013 Hi, something seems to be wrong with cooling management working with osxlatitude. Working with the same laptop under Windows, I don't have any issues, but under MacOsX after something like 2 hours of work, the laptop shuts off immediately and the body is extremely hot. After cooling down and a restart, I get the bios message, that the system was switched off to avoid damage. I'm not sure, but it seems like the cpufan just don't work properly under OsX. Anyone any idea how to fix this? Thanks for any help, Chapolote Link to comment Share on other sites More sharing options...
Administrators Hervé Posted June 6, 2013 Administrators Share Posted June 6, 2013 Can you please provide the specs and OS X version you're running (including the SMBIOS id used)? One possible way to improve this is to try and apply SMC fine-tuning: http://www.osxlatitude.com/tuning-performance-with-fakesmc-smbios-plist/ Link to comment Share on other sites More sharing options...
Darvinko Posted June 6, 2013 Share Posted June 6, 2013 The issue could indeed be the version of OSx. During the initial phase of getting ML to work on the E6400/E6500, we noticed heating issues with 10.8.0, which appeared to be resolved in updates.

Administrators Bronxteck Posted June 6, 2013 Administrators Share Posted June 6, 2013 yeah looks like you can use this http://www.osxlatitude.com/tuning-performance-with-fakesmc-smbios-plist/ use MBP5,1 as smbios Link to comment Share on other sites More sharing options...
chapolote Posted June 6, 2013 Author Share Posted June 6, 2013 Ok, need some help on this: you say: use MBP5.1 as smbios. If I understand the mentioned article well, i don't have to modify the downloaded FakeSMC.kext to smc-version 1.33F8, because it is already modified. Correct? On the other hand, following the article, the MBP which matches best Precision M4300 should be MBP3.1 with smc 1.16f11. Is it correct, that this would be translated in 6bit 01160F00 0011? So, are you sure, that MBP5.1 matches to my M4300 better then MBP3.1? I mean, if one, you should know Regards, chapolote Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted June 6, 2013 Administrators Share Posted June 6, 2013 01160F00 0011 would be correct for mbp3,1 but try the mbp5,1 version im guessing herve has it coded in fakesmc download. Link to comment Share on other sites More sharing options...
chapolote Posted June 6, 2013 Author Share Posted June 6, 2013 ok, i will try MBP5.1. Thanks a lot so far. Should i disable then PStateMenu? Regards, chapolote Link to comment Share on other sites More sharing options...
Administrators Hervé Posted June 6, 2013 Administrators Share Posted June 6, 2013 I can't remember if I coded MBP5,1 in that FakeSMC version, so check it! Disable PStateMenu to verify native SpeedStep operation. There's also a good chance that you can run without NullCPUPowerManagement (or maybe you do already), in which case, ensure your Chameleon boot plist has P & C States checked. Are you using a D830 or D630 nVidia DSDT? Link to comment Share on other sites More sharing options...
