memory Leak?!? How about NOT having your software on an ESTABLISHED OS work with a client hovering over your shoulders!!!!!!
You may have real reasons, but it looks to me like you should be ranting and stirring up a storm on the forums for your respective software rather then an Apple forum. Unless, of course, your software is written by Apple.
I, too, have been waiting. But I must point something out: when the Mac Pro systems came out, they were the cheapest most powerful systems on the market. No one could beat their prices for the same hardware. Not Dell or HP. Not anyone.
Even now, their prices are competitive and they offer the fastest dual Xeon workstations available on the OEM market today.
Intel upgrades were announced a matter of days ago and no one is offering anything for sale utilizing them. Not Apple, not Dell, not HP.
I don't doubt that when the new Mac Pros are announced that they, too, will be competitive in price and features and offer the best available in their class.
So, it seems to me that your main complaint can only be that some 3rd party vendor isn't supporting your platform of choice to the degree you'd like.
I'd suggest searching for an alternative that provides the same functionality, but with a better development team. If the software has no alternative or if the company is too invested in the use of this sub par mac software (bad managerial choice here, but sometimes we must adapt around previous errs in judgement or lack of rigorous investigation) then you have parallels or dual booting......or just buy a windows machine and deal with its quirks.
That's pretty much all your valid choices. So it's time to meditate on them and make the best choice for you and your company.
Of course, you could just hang out on these forums and rant about the short comings of OSX (which are really short comings of whatever sub par mac software your using), but at the end of the day you'll be no better off then the beginning.
