Why does MacOS X 10.6 'Snow Leopard' boot in 32-bit mode by default? How can I boot in 64-bit mode? What are the advantages of 64-bit mode? Are there any disadvantages? When originally shipped on August 28, 2009, Apple had MacOS X 10.6 'Snow Leopard' boot in 32-bit mode to ensure compatibility with non-Apple kernal extensions and drivers.

Mac OS X Snow Leopard has many enhancements compared to the previous releases. The performance of Mac OS X has been enhanced greatly and there is a reduction in the memory footprints. The name Snow Leopard suggests greater improvements in the previous Leopard version. Mac OS X Snow Leopard is a glamourous operating system for your Mac that says good by to the old applications and is aimed to provide a more refined UI which is with some more performance improvements, a good gesture and a hub for next generation 64 Bit applications.

As a result, most applications and peripherals that had yet to be updated to run in 64-bit mode would continue to operate without problems. Meanwhile, new 64-bit applications still would run with 'Snow Leopard' booting in 32-bit mode and may be faster than they were running with 'Leopard'. Since that time, Apple continued -- and still continues (as of the date last updated, see top) -- to ship most Macs booting in 32-bit mode by default. However, Apple the 'Mid-2010' models to boot in 64-bit by default. The advantage of booting in 64-bit mode is performance. Some 64-bit applications -- particularly those able to utilize more than 4 GB of RAM -- are when the operating system is booting in 64-bit mode. To startup in 64-bit mode for models that are not enabled by default, just hold down 6 and 4 when booting.

You will have to do this each time you startup, so if you discover that your system is fast and stable running in 64-bit mode -- and you have no out-of-date third-party kernal extensions or drivers -- you may wish to either make the change or try. This application makes it possible to set your Mac to boot in 64-bit mode each time.

Does MacOS X 10.6 'Snow Leopard' improve the performance of 32-bit Intel Macs or just 64-bit ones? Zakoni elektrodinamiki i princip otnositeljnosti prezentaciya. MacOS X 10.6 'Snow Leopard' provides the greatest possible performance boost for 64-bit applications running 'Snow Leopard' booting in 64-bit mode. However, 64-bit applications often are faster running 'Snow Leopard' booting in 32-bit mode than the same applications running under 'Leopard'.

32-bit Macs typically will see modestly improved performance running 'Snow Leopard' compared to 'Leopard', but the gains will not be as substantial as they are for Macs capable of booting in 64-bit mode.
