comment When updating your Mac OS X from 10.5 to 10.6 do you need to reinstall and reconfigure all of your software from 10.5?
(Anecdata): Mostly you won't have to. A few apps and some low-level things like prefpanes and extensions needed some tweaking, usually by upgrading to SL-compatible version. I followed snowleopard.wikidot.com for a while until I was comfortable that my gotta-have software was compatible (or there was a SL-compatible version) before I made the jump. I downloaded the 10.6.2 combo update before I did the OS update and applied it immediately after the update finished. I'm happy with the results on 2 iMacs and a Macbook.

comment Parameters for selection of Operating system, memory and processor for embedded system?
A client once selected an OS for his project before I was brought on or given a chance to comment. It lacked a basic inter-thread messaging capability which we needed so I had to divert some attention to implementing one before I could really get started. He paid more for that OS than some other, perfectly adequate ones, and paid me to make something one of the others would have included. Think about the OS facilities you need or want to support your design; that may guide your choices.

Unless your needs require / design assumes some special features not shared by most common OSes, I'd think about price (per unit royalties vs. once per project licensing fee), vendor's support reputation, developer support group availability.

Do you need all the speed you can get (DSP, perhaps) or will a common, off-the-shelf, single board computer support your product? With an 'x86 board, you likely already have a capable toolset on your development machine. You might need an embedded-system linker-relocater to replace the host (unix/MacOS/Windows) linker and a remote debugger, if not already provided. Will the board be available for the foreseeable life of the product? Or is the product a one-off or a short run? Then hardware is cheaper than you are; get all the capabilities you can to make the design & bring-up easier.

Essentially, yes. To estimate code-size, you have to start from somewhere. Why not your development machine? If your target will differ significantly, a DSP, for example, than at some point you'll need to estimate how your target's code size will compare to that of the development system, but you'll at least have some idea from seeing a few functions' worth of code size. But I'm still left wondering whether/why, at today's memory prices, you feel the system cost will be sensitive enough to code-size that you'd need to go through this exercise?
