In 2005, it switched again to Intel 32-bit and 64-bit x86. In 2011, Mac OS X Lion dropped support for Macs with 32-bit processors; in 2019, macOS Catalina dropped support for 32-bit Intel apps. Supported 64-bit Intel systems can still boot the latest versions of macOS as of January 2025.
64-bit Addressing: AArch64 allows the Cortex-R82 to address a much larger memory space compared to its 32-bit predecessors, making it suitable for applications requiring extensive memory. Example : A complex industrial automation system can utilize the expanded address space to manage large data sets and buffers more efficiently, improving ...
With the release of Mac OS X Snow Leopard, and before that, since the move to 64-bit architectures in general, some software publishers such as Mozilla [1] have used the term "universal" to refer to a fat binary that includes builds for both i386 (32-bit Intel) and x86_64 systems. The same mechanism that is used to select between the PowerPC or ...
macOS Big Sur is the first release of macOS for Macs powered by Apple-designed ARM64-based processors, a key part of the transition from Intel x86-64-based processors. [19] The chip mentioned in demo videos, and used in the Developer Transition Kit , is the A12Z Bionic .

Mac OS X 10.4.7 and higher versions of Mac OS X 10.4 run 64-bit command-line tools using the POSIX and math libraries on 64-bit Intel-based machines, just as all versions of Mac OS X 10.4 and 10.5 run them on 64-bit PowerPC machines. No other libraries or frameworks work with 64-bit applications in Mac OS X 10.4. [97]
Released in 2011, the ARMv8-A architecture added support for a 64-bit address space and 64-bit arithmetic with its new 32-bit fixed-length instruction set. [13] Arm Holdings has also released a series of additional instruction sets for different rules; the "Thumb" extension adds both 32- and 16-bit instructions for improved code density , while ...
