Frequent readers of this Blog know that I am a Mac user, running several Apple and Hackintosh systems (since 2001). Over the years Apple lost the hardware race and currently the only technology unique to Apple machines is Intel Lightspeed (aka Thunderbolt). Apple moved away from the professional market and is targeting mostly consumers, which also reflects in the supported hardware. Furthermore the future of the Mac Pro line remains unclear, since Apple might drop the line completely (it might face the same fate as the XSERVE line).
Here are my thoughts on why Windows 7 and Windows 8 might be a better choice for media producers and enthusiasts
* Current graphic cards are not supported on Mac OS X
Although there is some serious efforts by netkas in getting AMD 6950 and 6970 GPUs to work with Mac OSX, there are no currently known configurations that will work with Hackintoshes. The 6950/70 will work with patched KEXTs on Mac Pro Systems, but wtf? We have already the AMD Radeon 7970 Graphic Cards available for a decent price, so why should we bother with Apple being too late to the party? Unless there is a new Mac Pro with 79xx GPU coming out, we won't see any kexts soon.
* No SLI or Crossfire support and no dual-GPU support on Apple!
Mac OSX does not support SLI or crossfire - hell it does not even support multi-GPU cards such as the AMD Radeon 6990. Dual GPU-cards such as the ATI Radeon HD5970 only run with one GPU disabled on OSX. This is a serious limitation if you are creating media content such as 3D or video.
* Professional SSD-Cards don't run on Mac-based systems
Fast PCI-E cards, such as the OCZ RevoDrive 3 X2 Max IOPS 480GB, PCIe 2.0 x4 (1900 MBPs read/ 1700 MBPs write) or the OCZ Z-Drive R4 R Series (up to 2800 MBPs read/write speeds) are not supported on Mac OSX. The OCZ Revodrive X2 was reported usable with several Hackintosh configurations, but it is not that easy to set up, since some kext-magic is needed.
* Only limited hardware support on OSX, Sandy Bridge-E only with some hackery
Apple Mac OSX supports only very few hardware components, so mostly we have to get parts that are intended for a Mac Pro. There are ways to get to use the Sandy Bridge-E chipsets with Hackintosh (see the nanofunk post: Sandy Bridge-E Intel 2011 Socket confirmed working with Hackintosh), but still it's not easy as pie.
* Adobe Suite runs faster on Windows
Mostly because of all the issues described above, logically the Adobe Suite will run faster on Windows based machines. If Apple can not catch up with the demands of the pro-users and the enthusiasts, it might lose the professional sector after all - so Windows 8 could become the system-of-choice for serious media professionals again.
[Update 2012-03-11] with the Experimental Forum Build 1.3.21 the total of free space was reduced to 3GB and the import of 3gpp files was added.
I just confirmed this and got some 5GB of free permanent extra space on my dropbox account: using the Experimental Forum Build and being part of the beta test concerning the new foto/video upload feature. The beta client is available for mac, windows and linux.
The "Dropbox Camera Import" feature automatically uploads your photo and video content, when plugging in a SD-card or connecting your smartphone. The autostart of the Dropbox importer did actually not work when I tried on Linux and Mac OSX 10.4. On Windows, you'll need to have Autoplay enabled to get the automatic uploader working.
During this beta period, we are also offering additional free space to test automatic uploading of photos and videos. For every 500MB of photos and videos automatically uploaded, you'll receive another 500MB space bonus, up to 5GB total. The Dropbox space you earn is permanent. You can use it for the life of your account.
[Update 2012-2-22] the latest version of the Experimental Forum Build is 1.3.17 that fixes a lot of bugs and issues. I updated the links accordingly. If you are getting started with Dropbox, use this referral link to get 250MB of extra free space on signup.
