I just got Kalyway 10.5.2 up and running with Vanilla Kernel, and it's working fairly well so far. The problem I'm noticing is that my Intel Core 2 Duo (2.53 GHZ Dell Vostro 200) is only showing as "Total Number Of Cores: 1" under System Profiler. Should I be using a different Kernel? Or could it be a BIOS issue? Any help is appreciated. Thanks!

Update: I'm running 10.5.5 now and it still only shows up as 1 Core. I can't be the only person to have experienced this.

 

System Info:

 

Intel Core 2 Duo 2.53 GHZ

Foxconn G33M02 Motherboard

ATI Radeon 3650HD 1024MB

2 x 1GB 667 DDR2 Dimm RAM

500GB Western Digital SATA 7200 RPM Hard Drive

 

Kalyway 10.5.5 / Vanilla Kernel

Ok, I figured it out now.

 

I edited the com.apple.boot.plist file and removed the <string>cpus=1</string> line.

 

In case there is another Noob out there like me, this is how you accomplish this:

 

1. Open Terminal

2. Type the following (without quotes) "sudo nano /library/preferences/systemconfiguration/com.apple.boot.plist"

3. Type your Password when prompted and hit Return/Enter key (no characters showed when I typed but it still works)

4. Find the <string>cpus=1</string> line and delete it

5. Hit Ctrl/O and then press Enter/Return

6. Hit Ctrl/X, close terminal, and Reboot your system

 

This worked for me with a Core 2 Duo processor, use at your own discretion!

I am now having the same problem. I have been running fine for about two weeks now. Used OSx86tools to modify the "about this mac" as it was showing unknown. But I was getting the dual cpu meter on the top bar. after rebooting it gave me some garbage on the about this mac screen so I used osx86tools again to default it.

 

Now it shows 1.67 Intel Core Solo. When I have a Centrino Duo.

 

Activity monitor shows two different charts at the bottom so I assume it is still using both cores.

 

I tried the fix above but there was no CPU string in that file.
