how do I know if my mac is 32 or 64 bit?

Top left corner, click apple,

open about this mac

click on more info...

--- lot of data about your machine here ---

click on system report (or go to utilities/ system report -- its just more fun this way) 😁

1. Compare your Processor Name to information below
2. determine whether your Mac has a 32-bit or 64-bit processor.
3. all later model macs are 64 bit (unlike ms)

Thank you. I found my answer here quick and simple!

then what about 11.6"?

The current 11" Macbook Air uses an intel i5 64-bit processor.

The original 11" Macbook Air (Last 2010) used an intel Core 2 Duo 64-bit processor

The Core 2 Duo line was intel's first consumer 64-bit processors. I think the Xeon commercial line when 64-bit before the Core 2 Duo line. All the i5 and i7 intel processors are 64-bit.

its 64 bit and you don't leave enough specific information for anyone to assist. So go here everyman.com and look up your specific model.

M stands for Mobile. The Intel Core M is the line of mobile processors for the ultra thin computers. The 12" MacBook uses the Intel Core M Processor type.

If you are asking whether its 32 or 64bit, then its 64Bit. Intel has not made a 32Bit processor in several years.
