. in a pre-emptive OS there should be no freezing;

given the new concurrency model

that includes the use of the graphics processor GPU

to do the system's non-graphics processing,

my current guess is that the freezes happen when

something goes wrong in the GPU,

and the CPU is just waiting forever .

. the CPU needs to have some way of getting control back,

and sending an exception message to

any of the processes that were affected by the hung-up GPU .

. could anybody at discussions.apple.com

correct this theory or comment on it ?

    Hello,

     

    Is this true unending freezing where no control or force quitting can be used, or just freezing for long periods?

     

    Most of the 1st instance is from incompatible or damages .kexts that are at the heart of the OS to control/access the Hardware. Most of the second instance are due to reduced resources like RAM, Disk Free Space, or intermittent hardware problems.

    the problem typically happens when Apple upgrades the OS

    If you have 3rd party kexts installed, the likely need to be removed or updated when the OS changes.

    Have you every opened Console & checked the crash logs or system log for the causes?

    Automatic backups can freeze a machine that is too full.  Mac OS X requires at least 15% of your disk space to be free to avoid the most common freeze occurances.  I recommend Textwrangler for editing text files on the Mac.  And system wide automatic backups can really freeze if you have too many files.  I only do backups when my machine is unattended.

    Oh I'm quite familiar with them.  I suggest working with VMWare on finding out what may be tasking your system.  I use VirtualBox instead of VMWare.  You don't need Linux to run Komodo Edit:

    Running an entire Linux operating system on top of Mac OS X is a resource hog in of itself, and not all Virtual Machines are optimized the same way.

    No one is perfect.  Case and point your syntax does not meet English grammatical standards.  While fine in some geek realms, if you hope to obtain a job in an English speaking office, you need to understand as well as write more clear English.  Capitalize as I do every first letter of every sentence.  Attempt to put your periods and the end of the last word without spacing it from the last word.  Have a look at Strunk and White's "Elements of Style."  And once you can get a job as a programmer maybe one day you'll be able to get a job at http://www.apple.com/jobs.html and uncover the true weaknesses of Apple's kernel, and not just guess where they reside.  Because until then, all you have is hearsay about which system is more stable, and no way to really prove it.  I am not perfect either, but I make every effort as a 40 year old to communicate with the tools I am aware of.  Rules in English are the same as rules in programming.  They are there to hold the structure together.  You disregard structure at your own peril.

    My bad, Apple has moved the jobs page.  Google is your friend.  I have not the time to look for it now.

    http://www.apple.com/jobs/  Looks like they have a single link that redirects to the country they have positions in, depending on which country you are browsing from.
