10.6: How to boot into the 64-bit kernel

I just tried your link to the French spiderman story, Rob, and read the page and played the video with no problems.

System Profiler, System Software Overview reports "64-bit Kernel and Extensions: Yes

MacBookPro5,1
Mac OS X 10.6.1 (10B504)
Safari 4.0.3

I booted this MBP into 64-bit mode several days ago and haven't had to go back to 32-bit mode yet. Guess I don't have many plug-ins or extensions requiring the underlying applications to be running in 32-bit mode.

Unlike your guidance, I'd suggest people try 64-bit mode to find out whether it's problematic for them personally or not. As I'm sure you know, on a 64-bit processor a 64-bit kernel can run both 32- and 64-bit apps (but a 64-bit kernel can load only 64-bit kexts or kernel extensions).
