  1. Why I Believe the New Mac Pro Won't Be a Great MacHine for Gaming

    June 23, 2013

    In Accidental Tech Podcast episode 18 (love the show), I learned that John Siracusa was thinking about buying a new Mac Pro for gaming.

    I believe that gaming on the new Mac Pro will be a mediocre experience.

    Driver support: as John mentioned himself, the video cards are 'professional GPUs' used in workstations for computing, CAD etc. These cards and especially their drivers under Windows are not geared towards gaming performance.

    The performance and quality of Mac OS X drivers may be improved dramatically over the past years, but if you like to play games exclusively under Windows, you will probably be disappointed when you switch to bootcamp.

    Crossfire support: you have these two ridiculously fast GPU's and for years on the PC platform, you can stack them together to achieve insane performance (SLI / Crossfire).

    Mac OS X does not seem to support crossfire (or SLI). If you can't benefit from crossfire, you're paying a lot of money for a machine with one idle but very expensive videocard. That sounds like a ridiculous waste of good money.

    Assuming that the hardware supports crossfire, if you would run Windows, then you may hit the driver issues associated with pro cards.

    Upgrading: upgrading can be cost-efficient as most games are GPU not CPU bound, not an option for the Mac Pro. Even the new Thunderbolt interface does not have sufficient bandwidth to hook up one or more external high-performance videocards, aside from the fact that this will be insanely expensive.

    If you really needs the horsepower of a Mac Pro for other purposes than for gaming, sure it's the fastest mac you can get, but otherwise, I believe there's a better deal to be had.

    We don't now what the new Mac Pro will cost in a configuration suitable for gaming, but it will be 'a lot'. I believe that for one new Mac Pro, you will also be able to buy:

    1. a mac Mini with reasonable specs (it's easy to replace memory and storage);
    2. a high-quality 27" display @ 2560x1440
    3. a ridiculously fast PC that will outperform the new Mac Pro when it comes to gaming.

    I know that some Mac users don't like the idea of having a PC at home, but if you are into PC gaming, there's no other choice in my opinion if you want a good gaming experience.

    I had high hopes for my 27" iMac (2011) but gaming performance anno 2013 is just mediocre at best. And I can't use it as an external display with a PC, only with a Mac.

    So I sold my 27" iMac and used the money to buy a separate 27" display and Mac Mini. I also ordered a 'ridiculously fast PC' which I hope will allow me to play all modern games on max quality settings for now and the upcoming year. And if required, I can swap out the dual GPUs and replace them with something better over time, if I need to.

  2. Lion's FileVault Does Not Support Bootcamp and External Boot Disks

    Read the comments as they may provide useful information for your particular situation

    I boot my iMac from an external FW800 SSD. I found out that it is impossible to encrypt this disk using the new FileVault as part of Lion.

    no filevault

    Furthermore, I also found out that if you have a disk with a Bootcamp partition FileVault will also refuse to start the encryption process. I'm not trying to encrypt the Bootcamp volume, just the bootable Mac OS X Lion installation.

    no encryption with bootcamp

    It may be advised to stay away from Lion if you need a setup similar to this one and also need disk encryption.

  3. Lion's Disk Utility Not Compatible With CoreStorage and Filevault

    August 03, 2011

    My 1 TB hard drive of my 2011 27" iMac was partitioned with:

    1. A bootable partition with Mac OS X Lion
    2. Time machine partition (I use an external SSD as my main OS)
    3. Bootcamp partition with windows
    4. A data partition containg... data.

    The problem is that CoreStorage is too new. Disk Utility in Lion cannot cope with CoreStorage volumes. So when I decided to encrypt the bootable partition using the new Full Disk Encryption based on filevault, I could no longer manage my other partitions.

    disk utility

    Furthermore, bootcamp got killed since it needs to be installed on one of the first three partitions on the disk. Due to the whole CoreStorage stuff and filevault, it became the fifth partition and it got killed. I couldn't get it back to life It wouldn't boot.

    What I want now is to create a setup where I have three partitions:

    1. A bootable (Boot) clone of my external FW800 SSD boot disk using SuperDuper
    2. A Bootcamp volume running Windows (for games)
    3. A data partition storing well.. data.

    I want to encrypt the boot disk and the data partition. If this is going to work, I don't know.

    It may be advised to stay away from Lion if you need a setup similar to this one and also need disk encryption.
