I’m in the same boat. I want to transfer ZB back to the Mac OS side. Pixologic should be getting commissions from Apple, and Microsoft. I wasn’t planing on buying an intel Mac, or Windows any time soon, but I am suddenly in serious Mac Debt with a side order of Win XP 
V3? isn’t that cheating?

The congratulation used the friend of apple to buy!Regrettable I have no apple.
This is super news. I’ll be so happy to get rid of my Windows partition. So Long Bootcamp.
Awesome - now fix the zSphere bugs and your legitimate-user-nuisance-licensing (aka expensive-futile-piracy-protection) for real computer. 
You are so dead on!!!
How do you know the Mac version has zSphere bugs???
Maybe we should hold off with the rants until we’ve all actually used it???

I’m not picking sides, but maybe they should of posted the bug fixes if any, so the lack of them did not cause people to assume they are still there.
As it looks right now they are still there. I would assume they are unless otherwise notified. Anything else is just wishful thinking. If they fixed them wouldn’t they say? Why would they fix them in the mac version and not PC?
I DO agree about the useless licensing. I’m on the east coast they are on the west coast. My zbrush license broke thursday in the morning. I had to wait 4 hours to call them when I had a deadline in the afternoon. I was at my wits end and nearly had to crack software that I own. It is not stopping piracy it is only stopping legitimate work. But that is a industry wide problem. Zbrush license breaking on the other hand is a pixo problem.
Double post sorry.
I am both happy and sad about this announcement. I am happy that it is finally going to arrive-but sad that it is only Intel compatible (I don’t have an Intel Mac). What I would like to do is to get my copy and hold on to it until the day I do get an Intel Mac. This brings me to my questions:
1 I know that the upgrade is free, but will there be an upgrade CD that can be purchased for a small price? I would hate to download it and then not know (until I get my new Mac) that the downloaded version got corrupted during the download.
2 Will they let me re-down load it in a year or so if I do have a corrupted file?
3 PC people, did Pixologic offer a CD upgrade version for you?
For over a year now I’ve been asking your tech support department if zbrush would be supported on the power pc platform, and they continued to assure me that it would, now this
“Regrettably, it will no longer be possible for new versions of ZBrush to support the discontinued Power PC platform.”
Please let me tell you that I have never been so angry at a software company in my life. I despise you for this.
Yes they did so I imagine one will be available for Mac though they might wait for 3.5 and offer CDs to Windows and MAc license holders.
If Pixo wont send you a CD for a few bucks, I’m sure anybody from this community will do it. I’m sure you’ll have some help. Just ask …
But its sure Pixo will do it also.
Hey that’s my birthday. How fitting!

yipee!!
I am glad this update is finally coming through!
However, there is something I want to know: will it be 64bit compatible?
I mean, Leopard is already fully 64 bits and as much as I love how ZB3 benefits from multiple processors/cores, I grow increasingly frustrated with the inability to give ZB what is really craves: lots of RAM.
With other competitors coming out with fully 64bit-capable builds, I feel awfully tempted to sculpt without worrying about memory compression and swapping, and finally give my 8 Gigs of RAM something to do other than Maya… but I still love ZB…
Looks like I just need to remain in “wait-and-see” mode…
Thanks for the update though guys! Much needed!!

I don’t know what to say… 
Awesome news!

I was getting really tired of rebooting every 5 minutes
Nice, I placed my order almost immediately, but wait since 3 days for a response, neither of both register requests have been answered… guess they have to much to do.
I think you need to buy a book on how to use your Mac. Probably ‘Mac OS X for Dummies’ as anyone using a Mac would have to be a dummy to begin with.
ZB will obviously be released in .dmg image file, and .dmg files contain an embedded ‘checksum’. If the .dmg verifies, them the only thing corrupted is the user.
… As you probably don’t know what a ‘checksum’ is… having never used a real OS, I suggest you visit a ‘Linux’ or ‘Windows’ tech forum and ask someone to explain it to you…
