how do you know find out while in operation which kernel you are running in ?
This is at least one way...
System Profiler>Software>64-bit Kernel and Extensions (Yes or No)
As the post in osxdaily says, open a terminal and type uname -a
I did it, and i found out that my MBP is running a 32 bit kernel. (!)
I thought that this type of machine should be using a 64 bit kernel.
I'll try to boot into 64 bit mode holding '6' and '4' during boot, but how can I make this mode the default?
I think this might work?
Thank you, I'll give it a try
Couldn't you also open Activity Monitor and look at the Kind column for kernel_task? It should say Intel for 32-bit and Intel (64-bit) for 64-bit.
In the terminal, type uname -a
If it ends in _x86_64 then you have the 64bit kernel.
