WOW!
I just upgraded an from my old 32bit iMac to a new MBP with 16g ram and an i core 7 processor, only to discover that my brand new $3K laptop can't even provide me with a functional mouse!!!
Worst still, i now read apple has been aware of the problem for over 2yrs and it STILL not fixed.
I upgraded because i finally tired of all the glitchy crash causing bugs that my iMac had developed. I put them down to being due to the iMac being 5yrs old and having worked pretty hard every day since i unpacked it from the box.
Looks like that might have been a $3K mistake.
I read that i can buy a 3rd party app for between $2 and $7 that will give me a work around to Apple's problem. Really, how convenient! So, Apple reviews, approves and lists on their App Store, an app purely designed to mask a fault in Apple's own operating system, that they've not been able to resolve in over 2yrs! Surely i'm not the only one who sees the irony in that?
If you can't fix the problem Apple, then at least show us the respect of providing us all the App for free, until you can!
The 2 x $800 PC's i bought for my kids seem to function perfectly.
If i had experienced this issue before purchasing the new MBP, i would never have purchased it. It's that frustrating! Seriously considering taking this MBP back and exchanging it for one of those, now.
Would never have happened when SJ was alive and in charge. Apple has really lost its way since he left this earth!
