Hi all.
Per this Wikipedia page (under section
4.1 64-bit architecture ), on my machine, the
64-bit Kernel can be enabled by pressing the
4 and
6 keys during boot. It also said, I can permanently enable 64 by changing
com.apple.Boot.plist.
I checked Profiler, but didn't see anything showing which kernel I'm using.
I tried the 4 6 keys, but wasn't sure if anything changed. Firefox did an upgrade when I launched it, so couldn't use that as a measure. iTunes seems to load at the same speed, but Britannica 2008 seems to load faster.
Three questions. How can I determine which kernel is running? Any pitfalls in changing kernels? And what in
com.apple.Boot.plist do I change?
