Laptop is very laggy

23 October 2014 - 11:35 AM



Recently I installed 10.8.2 on my Laptop (for some reason it permanently freezes shortly after boot if I update to 10.8.5. or if I install 10.9 so I stick with 10.8.2. which is OK for me). 

So far the system looks good, I got sound and LAN to work, too. 

And everything seems great in the beginning (according to Geekbech the performance is OK).


But the problem is, the system hangs a few seconds when opening or closing an application and this is getting worse the longer I use the system. 

Activity Monitor shows nothing unusual but when an application hangs, then the CPU usage goes beyond 100%.



The Hardware is (MSI EX600): 

CPU: Intel Core 2 Duo T5750 2,0Ghz


Chipset: Intel PM965

LAN: Realtek RL8111B/8111C --> Working with Lnx2Macs RealtekRTL81xx.kext

Graphics: NVIDIA GeForce 8400M G --> working (I think)

Audio: ALC888 @ Intel 82801HBM ICH8M --> working with Voodoo Kext

WLAN Atheros AR5007EG Wireless --> not working but I bought me a D-Link DWA-131

DVD-ROM: Not working (I think its a ATA not a S-ATA)


For SMBIOS I used MacBookPro4,1 (I also tried 3,1 as these both came with C2D CPUs).


I installed FakeSMC, ElliottForceLegacyRTC, Ev0reboot, JMicron36xATA, AHCI_3rd_Party_SATA and NullCPUPowerManagement and patched AppleRTC.


I already removed AHCI_3rd_Party_SATA as it is not needed and I think I can delete JMicron36xATA too.


And I tried with and without NullCPUPowerManagement.kext but no change.


My chameleon.boot.plist looks like that:


<key>Graphics Mode</key>

<key>Kernel Flags</key>
<key>Legacy Logo</key>
