![]() Also, the new MacBook Pros boot into a 64-bit kernel - the older ones booted into a 32-bit kernel (even though they had 64-bit CPUs, and either way allows 64-bit apps). The processor is listed in About This Mac under the Apple menu.ĮDIT TWO: Perhaps VirtualBox's CPU detection code incorrectly identifies the Sandy Bridge (2nd generation) i7. To confuse things further, after "Core 2", Intel dropped the "2" and used "i"-something: This also means this Mac cannot run OS X Lion (a requirement of the current beta which seems likely to persist to release). VirtualBox does allow 64-bit guests on hosts running a 32-bit OS, but still requires a 64-bit processor ( with hardware virtualization support). Mac OS X is not Linux - they are cousins.ĮDIT: Apparently you have one of the early Intel Macs, which had "Core Solo" and "Core Duo" - not "Core 2 Solo" and "Core 2 Duo" - processors. ![]() Unix is a common ancestor of both Mac OS X and Linux. (Intel tried an earlier 64-bit processor named Itanium, but it didn't catch on, so they adopted AMD's approach.) Longer answer: "AMD64" applies to both AMD and Intel.
