Hi guys,
I updated my MacBook White yesterday to Snow Leopard, surely the speed has increased with startup, shutdown, Safari, Mail and some other stuff. I also noticed that the icons have improved graphically and the colors have enhanced greatly also that I have got back an amazing 10.40GB back when it said that the installation will free up only upto 7GB, although i have a couple of question which im unsure about:
1. Since Apple said that upgrading to Snow Leopard enables the user to use 64-bit computing, but when i checked in the System Profiler=>Software it says "64-bit Kernel and Extension : NO" but when I open up Activity Monitor it shows all the applications running in 64-bit, yet when I double checked it from Terminal the results are 'EFI32', since I read on the forum that if I have an Intel Core2Duo I have 64-bit processing power but on the other hand somebody suggested to run the script on Terminal to check whether I have 64-bit processing capabilities. My question is that do I have 64-bit processing power and if I do how come I can't enable it by pressing '6' and '4' on the startup?
2. Most of the forum said that Apple has made the MacBook by default to boot on a 32-bit Kernel and if one wants to experience 64-bit processing then needs to hold '6' and '4' while booting, once the 64-bit kernel is enabled by this process then the next time I reboot the system will it again start on 64-bit or the default 32-bit and if starts on a 64-bit kernel how can it be reverted?
3. After the upgrade when i went to my Movies folder and selected a video clip with a .avi format and previewed in QuickLook it never played, I can only hear sounds but no video!! and my real player doesn't work aswell! any solution to that and why is this happening?
4. New technologies like Grand Central Dispatch, OpenCL, CUP and others do they only work in 64-bit kernel or they support 32-bit likewise?
Please suggest, your answers will be greatly appreciated.
Thanks
