The first Intel Macs used a 32 bit Core Duo CPU. And while they were discontinued at the end of 2006 (with the exception of the 1st gen Apple TV which lasted until 2010) applications released after were often still 32bits to support them for several years.
That was the first Mac OS with 64 bit on Intel silicon. 64 bit PPC was supported by OSX 10.3 Panther in 2003. The 64 bit versions of Windows Server 2003 (both ia64 and amd64) didn’t release until 2005.
Huh, Mac has 64 bit.

The Powermac G5 was the first 64 bit consumer desktop, it predated the amd64 version of XP by 2 or 3 years
Um, first Mac os with 64 bit was in 2009 compared to Windows 2003 (XP server) or 2006 Vista.
