I've taken a couple of years off from working with Poser after my last experience with P5 (which was abismal).  About a year ago I upgraded to P6, but my current machine couldn't handle it, so everything was once more put on the shelf while I worked on real-world home improvements.  Things are winding down now and I'm ready to start modeling again.  

After years being "PC" I'm about to buy my first Mac.  After careful consideration, I want the new "Mac Pro".  

Q:  Is there anyone out there on a Mac Pro running a dual 2.66Ghz processor with 4Gig RAM and using P7?  

I've searched the forum for "Mac Pro" and found lots of speculation about the new Pro chipset and PC vs. Mac discussions, but nothing with a recent date about how the Pro handles Poser 7.  I want a Mac Pro  with the above specs with the idea I'd upgrade in the future as money allows.  To help determine if I really want to buy P7, I must ask the following questions:
Q:  Which video card should I choose?  
Q:  Is P7 as RAM hungry as P4-6 seemed, or has the programing changed to take advantage of the new technology?  
Q:  Will 4Gig RAM be enough to quickly render static images (no animation)?
Q:  Will old PC Poser files transfer to the Mac program if they are already uncompressed?
Q:  How much of a hassle is it to use the MacConverter program to use typical Poser content?
Any advice is greatly appreciated.

Hi TygerCub, I have the new Mac Pro with 3 gigs, and I haven't had any issues with memory. There are some hairs that can make the renders crawl, but you can work around it. I suspect my old PC wouldn't have even been able to ever finish those. I am using the video card that was cheapest and it's fine. I don't know what the more expensive one would be like, though. For Poser, I can't imagine it would help any. As for the windows runtime to the mac goes, everything will be fine. Just make sure you are meticulous about getting all the pieces from your windows P7 runtime copied over. I missed a bunch of injection stuff, and am slowly replacing it as I come across them. The RSRs that haven't been converted will show up missing:( And DAZ will go out of their way to support Macs without bothering to actually make PNGs (who knows why). Most products they release do have pngs. I haven't used Mac Converter myself. I've been making a note of which folders are messed up and fixing them with P3DO Wizard (or what it is called) when I have the time (from my old windows machine). There is a shareware app that will do it for you for $10, I think. Probably worth considering if you have lots of stuff that is missing the icons. Everything I've used has worked on my mac. I tried a couple of programs that I knew had Mac support and they worked fine (Wardrobe Wizard). I haven't tried the ones I had bought that have PC & Mac versions, though- so you might have to repurchase any of those you had bought before. Frankly, I love my mac, and don't have any real regrets switching.

martin c's maconverter is no longer needed. in regard to older daz installers, OS 9 may still be needed. I don't have a mac pro, but P7X is approx. 1000X better than P5X IMVHO.

Thanks, mamba-negra!  
Hm... I never worked with injection stuff even though a couple of items I purchased had it available.  Injection tech was relatively new when I last purchased Poser content.  I can see there will be tons of stuff to learn if I pick up P7.

Miss Nancy, if I purchase P7, it will be the Mac version and I have gigs of .zips and .exes that will need to be re-installed... I won't need maconverter for that at all?  Could you elaborate on the OS9 comment, because I'm a clueless newby and am unfamiliar with OS9.

Thanks for the comments!

The new Macs will be running OSX. Intel Macs cannot run OS9 ("Classic mode"), which is one of the older Mac OSes. Unfortunately, some of DAZ' installers rely on Classic mode to function; they are primarily the ones for older items that haven't been updated to work under OSX. .exes don't run at all on the non-Intel Macs, though I'm not sure about the Intel Macs. I believe there are ways to do it, but it may not work 'out of the box'. I don't believe the MacConverter is required any longer in OSX -- at least I have never needed it. For .rsr to .png conversion, there is a nifty little application called xShruggy that handles it, and is, IMHO, well worth the small shareware price they ask for. The DAZ items that don't have pngs usually don't have the rsrs either, though, so you may end up making your own icons for those items.

Oh, I hadn't noticed that! Why would they do that? Do those files actually have the old resource fork junk that was required by pre-OSX?

The thumbnails? I really wish I knew. They may show up fine on an Intel Mac -- no clue. I just know they're not the shrugging guy, but just round spots of nothing on my system. (One of the very last non-Intel Macs.)

tyger, in regard to OS 9, it was the predecessor to OS X, but it was dropped as an evolutionary dead end. in regard to any zip/exe files, you may know that the newer intel macs will boot into tiger/leopard, XP and some versions of vista. hence you may be able to use vista/xp to extract or install said zip/exe files. OS X can open zip files and exe files which are compressed archives, but it can't open exe files which are installers or self-extracting archives. philc has got an utility for OS X users to ease installation of zip files, as does poser 7 and kaveman (see mac forum here).

There's also BetterZip for the zip files. It works very nicely, in my experience -- though I do install into a temporary folder before shuffling things off to the runtime as a general rule.

Mac forum?  Okay, I'm blind... I didn't see anything for Mac in the forum list....

DOH!  Nevermind.  (found it)

I really am quite stupid.
