Recently I’ve been having a few issues with my new MacBook Pro- doh! There’s a lot of talk online linking it to overheating issues with the cpu/gpu but the suggested workarounds haven’t helped. Yesterday I booted OSX using the 32bit kernel instead of the 64bit kernel (holding the 3 & 2 keys whilst powering on the mbp) and, fingers crossed, no problems since!
I have been running some intensive apps: handbrake, vlc with external monitor connected via displayport/hdmi etc and stressing the laptop and everything seems AOK!
I’ve posted my findings in a long discussion thread on the apple forum: https://discussions.apple.com/thread/2768351?start=1290&tstart=0
Some of the ways in which the freezing / hanging / crashing has manifested itself:
-laptop refusing to wake from sleep
-coloured wheel appearing and being unable to do anything
-extremely loud beeping coming from the system speaker I think?
-panic
Keep you posted.

*Update* A week on and still running rock solid, so it looks to be an issue with the 64bit kernel.
Hi there. I am looking forward to buy a new macbook pro. I am a business and accountancy student and somewhat into hobbying of programming using c & c . Apart from this I love to watch videos and play games like portal left 4 dead2 etc. Sometimes I edit my personal pics and videos before sharing them with friends and family.
So in all I am a very diversified user and just like to use a computer to get my work done and learn new things.
I am considering to purchase higher end mbp 15. After reading so many issues about it. I am a bit scared. Do you think I should go with mbp or wait for sometime before apple officially rolls out a proper solution to its issues.
Thanks! Awaiting response.
personally i think i would wait just a tiny bit longer
i got fed up mine crashed a few more times recently so took it to apple and got a new replacement
the replacement has crashed a few times but had replaced the ram and think it might be the cause- swapped it back and seeing how it goes!
