First of all, if you have not done anything, again, osx is all 32 bit mode. That being said,
1. Open about this mac, by vo plus m 2. Open more info. This is the same as the system profiler. 3. Go down to the software section. 4. take a look at the software overview and it will tell you Kernel and ext 64 bit mode or 32 bit mode. By default, it is 32 bit. Now, I have used on 64 bit mode for the last several months. I have not noticed any incompatibility issue. With some system speed tools, I can observe about 7 percent of speed gain but it is not that noticeable. More information about how to change the default into 64 bit can be found here: http://www.overclock.net/mac/564147-how-enable-64-bit-default-os.html On Nov 11, 2010, at 2:44 PM, Nektarios Mallas wrote: > Hello there. > How can you tell in which mode you are in? > Is there any menu or dialog to display that? > > Nektarios. > > On Nov 9, 2010, at 11:19 AM, Nicolai Svendsen wrote: > >> Hi! >> >> Well, you're already booting in 32-bit by default, so you don't need to.
