This is just a thread for anybody to report how they feel about their new Mac Pro after about having it for six months. Mine is that I got a six core, 256 GB, D700 sight unseen when it was first released. My company has a corporate discount program with Appleso I also got a nice price on it. I bought it for general use and software development. Previously I own a 2009 single CPU MacPro which was nothing but trouble. The main problem being that I was trying to upgrade the machine in various ways, such as eSATA and USB cards. You see at the time Apple had a number of bugs with their driver subsystem. The first was with eSATA. After much pain and trouble using it I found that they had a bug with hot swapping. It actually was worth than that, I think they had a couple of other bugs they weren't talking about. Apple is very good about this, they never or rarely talk about their bugs are failures and they have plenty, especially in driver code. The second problem was with their USB subsystem, it just never worked reliably. It was horrible, I had a USB mouse attached and then suddenly it would go bonkers. Third-party keyboards would fail to work upon resuming from sleep. There's nothing will make you trust a computer less than having USB devices that don't work. And of course the final thing is that that Bluetooth is basically useless. I tried to solve that with a Bluetooth dongle but then the USB subsystem problems cause up to fail intermittently. I just couldn't get keyboards and mice to work reliably, unless I used the Apple prescribed versions. It took a couple of years but finally a few of the system upgrades included bug fixes which actually fixed the problems, but by that point I simply didn't trust the computer to be the workhorse that I needed. Additionally the computer was loud and a power hog. Every time I turned it on the lights flicker and during the summer my room to get too hot to use. And even in the winter it would get a little bit too toasty. I tried various other Macs, such as laptops, they can never adapt to that kind of work. I'm firmly a desktop kind of person. Enough of the old, now with the new. The new Mac Pro has been everything that I wanted. It's dead silent, powerful and can take everything that I've thrown it. First the upgrades, I put 64 GB of RAM and it which is important for all the virtual machines I run. Second I put to promise Pegasus two Thunderbolt drives in it. The first thing that I'm looking for with the computer like this is absolute stability. I get 16 workspaces set up for the various activities that I do and I ideally want to never reboot my computer. It takes a while to get everything tweaked and set up the way that I want. On the MacPro part I haven't experienced any problems. Well there were a few problems early on, one was with the MacPro having a hard time going to sleep. I think they put out a bug fix for that. Otherwise it's been nearly flawless which is super important. The second is the external hard drives. Now there is a bug there. I have these drives off in a equipment cabinet for noise. I need 23 dB or less near my desk. I'm using a Corning 10m optical TB cable to move them over there, and the problem is that when Daisy Chained the first one in the chain won't turn off the fan when it sleeps. After much trouble I finally got Promise to duplicate the issue and now their working on it. By the way in one of the drives I have 4x256GB SSD's and have 6TB of spinners in the other, so I've got speed and size. This was a very expensive computer, but it's the most powerful, quietest and useful computer I've had to date (and I've had a lot of them). I also have a PC gaming computer with AMD 295x2 GPU, 4GHz CPU, SSD etc, and it's loud and tweaky. In my hack shack I have a powerful Linux computer, which is stable and runs fine, but doesn't have the OS X polish and usability (the terminal emulation is a joke after iTerm). My PC is probably more powerful, and a lot cheaper, but stability, fit and finish count for a lot in my daily work. My only other upgrade plan is to 1TB OWC flash whenever they release it. I have no interest in upcoming nMP upgrade releases, I'll use this one for 6 years at least. I still have the old Mac Pro and use it for a few things, in fact it's opposite the new one on my circular desk. It's just not that fun to use when you factor in the noise and heat, even though the bugs have finally been ironed out. I did upgrade to the 750 GPU, maybe I'll use it as a Windows machine which is presently on Boot Camp. I do still use the eSATA for external offsite drives. That ended up being longer than I intended, but please share how the new Mac Pro is going for you too.
