Ask TUAW: OpenCL support in Snow Leopard, Boot Camp, automatic importing into iPhoto, and more
Wednesday means it's time for another Ask TUAW! For this edition we've got questions about what Macs will support Snow Leopard's forthcoming OpenCL acceleration, using Boot Camp with multiple partitions, connecting a Mac mini to HDMI, automatically importing images into iPhoto, and more.As always, your suggestions and questions are welcome. Questions for next week should be left in the comments. When asking a question please include which machine you're running and which version of Mac OS X (we'll assume you're running Leopard on an Intel Mac if you don't specify). And now, on to the questions.
Jerry asks
What's the top three graphics cards for a 2008 Mac Pro to run Snow Leopard?
Stephen asks
Shouldn't a late 2008 iMac be capable of taking advantage of Snow Leopard's OpenCL? (if not the MacBook which has weak Intel graphics)
If you check out Apple's Snow Leopard Tech Specs you'll see that OpenCL is supported on the following graphics chipsets:
- NVIDIA Geforce 8600M GT, GeForce 8800 GT, GeForce 8800 GTS, Geforce 9400M, GeForce 9600M GT, GeForce GT 120, GeForce GT 130.
- ATI Radeon 4850, Radeon 4870
MacFixIt conveniently translates this into Mac models, revealing that, unfortunately, your iMac (and mine, too) will not support OpenCL. That doesn't mean, however, that your iMac won't benefit from Snow Leopard. Other enhancements and optimizations, including Grand Central, will benefit your Mac.
As far as the best graphics cards for the Mac Pro in Snow Leopard: strangely, it seems that the most powerful cards Apple sells aren't officially supported right now (e.g the GeForce GTX 285 and Quadro FX 4800). So at this point it appears that your best bet is the Radeon HD 4870, though it's certainly possible that Apple will expand support for the more powerful cards before Snow Leopard ships.

I have a Macbook Pro 2.4 Ghz (not unibody) running on OS X 10.5.7. My problem is I want to install bootcamp, but I have 2 partitions (system and data). Is there a way to install bootcamp without deleting the second partition (data), installing boot camp and creating the second partition again?
According to the Boot Camp 2.0 FAQ, "Boot Camp Assistant only works with an Intel-based Mac that has a single hard disk partition." So I don't think there's any way to use Boot Camp to prep your Mac for dual-boot without eliminating that second partition. In any case, you shouldn't do anything without a full backup of your disc. If you use SuperDuper! or Carbon Copy Cloner to clone both of your present partitions it should be relatively simple to restore your present setup after installing Boot Camp.
For nondestructive partition management (still back up, though!) you may want iPartition. You can also check out this guide to triple-booting your Mac, if you want to throw Linux on there somewhere.
Caroline asks
I seem to recall setting up a .mac account when I first got my MacBook, around a year ago. I have since forgotten the login details. How can I find them out again?
Apple has a couple of pages for recovering MobileMe info. If you remember your Apple ID you can get your password starting on this page. If you can't recall your Apple ID, you can click on the link below the Continue button on the same page.
gregtimm asks
I just bought my first mac, a 24 inch imac. I have a question: what is an alias, how would I use it, and why?
An alias is a "stub" pointer or link to a file somewhere else in the file system. You use them to create shortcuts (as the corresponding feature is known in the Windows world). You might use aliases for any number of things (created by selecting a file and hitting: ⌘+L), such as creating shortcuts on your Desktop to often-used folders or applications.
Aliases are Mac OS X-specific, and don't work when copied or shared to other operating systems; they are distinct from the UNIX-based symbolic and hard links, which also provide Mac OS X with methods of referring to the same file in multiple locations. Leopard's Time Machine backup utility uses hard links to do its backup magic, but 99% of Mac users will never need to know the difference between aliases and links; just make aliases like you would make shortcuts in Windows and everything will behave as you expect.
Brian asks
Getting a HTPC going, and i've decided on a mac mini. Using a 52' Sharp Aquos TV. I was just wondering which I should be using for my video mini-DVI port or Mini DisplayPort? Either way I'd be getting a __ to HDMI adapter. Is there an advantage for either one when used for a TV rather than a computer monitor?
Either should work more or less the same way, since it's going to be digital throughout the signal chain. However, I've seen some people reporting problems with going from the mini-DVI port to HDMI with some sets (perhaps related to HDCP DRM). That being the case, I would go with the mini DisplayPort to HDMI, with an adapter such as this one from monoprice.
Rob asks
Is there a way to set up "smart folders" in iPhoto '09?" I'd like iPhoto to watch a specified set of folders and automatically add photos to the iPhoto library as I add them to my hard drive. Is this possible?
Far and away the easiest way to do this is with the brilliant utility Hazel ($21.94) from Noodlesoft. It has a built-in option to allow you to set rules to watch particular folders and import their contents into iPhoto. It also does many other useful things as well.
However, as another reader suggested you can do this for free with Automator and Folder Actions. Start Automator and create a simple Action with (1) Get Selected Finder Items and (2) Import Files into iPhoto. Now save this as a plug-in for Folder Actions and attach it to the folder you want to watch. From now on anything you drop into that folder should be imported into iPhoto. You can add this Folder Action to other folders as well simply by right-clicking on a folder, choosing "Configure Folder Action..." and then adding the same script to that folder.

bleh, looks like my mac won't benefit from SL (it's a mid 08 macbook).... f-it i'm still gonna install it anways!!!

Your MacBook will still benefit from Snow Leopard. Grand Central Dispatch is likely going to be more important then OpenCL for most users. GCD should even show some improvements on the old Mac Mini with a Core Solo processor, though not nearly as much as it will on a dual, quad, or 8 core system.
OpenCL isn't that big of a deal for most Mac consumers. iApps might take advantage of it for rendering effects a bit quicker or video compression, whereas GCD benefits will be shown with nearly every bundled OS X app.

My mac luckily just makes the bottom requirements. I have an early 2008 MacBook Pro with an 8600M GT.

" just make aliases like you would make shortcuts in Windows and everything will behave as you expect."
No - it won't!!! If you move the target of the alias, the alias still works and it works instantly :-)
Windows instead will try to find the target as soon as you click it for the first time - and if this takes a while on a huge disk with many subdirs, it will present you a dialog saying that Windows can't open the target of the shortcut and offers you to either let Windows search for the target or name it yourself. You can analyze that behavior by looking at the properties of a shortcut - it will contain the last known location of the target until you click the shortcut for the first time.
Aliases need support from the file system - and that's why this neat feature won't work on all filsystems that way, but just on HFS+. If you right-click on an alias and select "Get Info", it will always name you the current location of the target - not the last known location.

Correct! I believe Mac OS X uses the more fundamental "inode" of a file for all such things - aliases included. Moving the file won't change it's inode. Nor will renaming it.
Ever try renaming a PDF file while it's open in Preview? Or moving it? No problem, Preview will even show the updated name in the window bar. Try the equivalent actions in Windows.

For chowee2 and the Boot Camp question:
If you use the terminal to partition the drive you could actually do it. I have 3 partitions on my MacBook Pro (1 for OSX, 1 for Linux and 1 for XP) and I used the diskutil command to split my original 1 partition into 3 before installing.
The Boot Camp assistant is basically a glorified partitioning tool. You can do everything w/o it.
I did this in the Terminal:
"diskutil list" (without the quotes, to get the disk identifiers)
You have to shrink an HFS+ volume, but someone correct me if I'm wrong. Remember the disk identifier of the partition you're shrinking. Also, decide on sizes now. When you shrink the volume, the sizes must add up (if you start with a 150GB volume, what you shrink to and the new volume you create must add up to 150GB).
Next you use resizeVolume to shrink one partition and create another
Say you had a 150GB partition for OSX, and you wanted to make that 120GB for OSX and 30GB for Windows you would run:
*diskutil resizeVolume diskxxx 120G "MS-DOS FAT32" "Windows XP" 30G*
Remove the asterisks and replace xxx with the disk you're changing (ex disk0s2; this will shrink a 150GB partition to 120GB and create a FAT32 partition sized at 30GB for Windows.
Next just insert the Windows install disc and boot to that, and proceed with setup like normal. Just install to the partition you created for Windows (it should be the only FAT32 partition available; I would recommend doing a quick format to NTFS though).
Side notes: I use rEFIt as a graphical boot manager, and you can get the MacDrive software to access your OSX partitions in Windows.
Hope this helps!

And always make a backup before playing with partitions. resizeVolume is supposed to be non-destructive, but backups never hurt anyone. I never had any trouble when I used it, but better save then sorry.

Dear TUAW,
i would like to know if anyone is aware of the porting of the video recording functionality on the 3GS to the 3G. I've seen a few blog posts (modmyi especially) where people are very close to getting it working. they have modified the files to accept the slower processor on the 3G, but cant seem to get it working 100%. it IS possible to get all of the features that the 3GS uses for video recording (minus the auto-focus and 3mp cam) to run on the 3G. People have been able to get video editing to work as well as the slide to record screen on the 3G. One of you guys should really look into this as i believe this will be the next big thing/hack. I'd really love your thoughts and any knowledge you can dig up. this is my 3rd ask tuaw and i think it would be a solid point, and would make a lot of people happy.
thanks!

Oliver: Google 'Cycorder.' Apple will not permit a video recording app in the store for the 3G phone, you will need to jailbreak.

On the discussion of HDMI cables, I now buy every cable I could ever imagine using from Monoprice.com. They have an amazing selection, unbelievable prices, and really know their stuff. Everyone else is a rip off compared to them.

Monoprice is far and away the most inexpensive and has the largest selection of A/V cables of any site I've come across.

I'm pretty sure Disk Utility now has nondestructive partition management, how come that wouldn't be enough?
Reply
Michael said 11:55AM on 7-08-2009
Disk Utils non-destructive work is only sufficient:
- if you don't make mistakes.
- if your machine doesn't crash or Macbook doesn't run out of at a tricky step of partion table modification.
- if it doesn't have bugs.
In an ideal world, none of the items of the list would ever occur. But if you love the data on your hard-disk, you do not simply rely on the ideal world, but make backups before messing with disk partitions.
Having TimeMachine, keeping your backups up-to-date normally takes less than 5 minutes - so nothing compared to the hours it would take to make a full backup of the entire harddrive before starting partitioning ... so even in the slightest chance of something bad happening, it might be worth it compared to the hazard of getting back your system and data in case something goes awfully wrong.

Will the 8800 GS video card in the 24" 3.06GHz late 2008 iMac work with OpenCL. Apparently the 8800 GS is another name for the 8800 GTS.
Does anyone know for sure?

noza said 10:55AM on 7-08-2009
Keep in mind that MacFixIt's list is just for base configurations. My 2008 iMac was CTO'ed with a 8800GS and works just fine with OpenCL. If you're machine is new-ish, but not on the list, check your video card before getting too depressed.

Questions for next week:
I'm eager to upgrade to iLife and iWork '09, but I'm also budget conscious (a hard trait to maintain as a Mac user). The reason I have held out so far is that I'm waiting for the Mac Box Set with Snow Leopard. Given the announcement of Snow Leopard's rock bottom pricing, will Apple still be offering a Mac Box Set? Will I be saving any money by waiting, or should I just buy iLife (family license) and iWork (single user license) now, and pay my $49 (family license) when Snow Leopard comes out in September. Thanks!

Tom said 11:17AM on 7-08-2009
There will be a Snow Leopard Mac Box Set per Apple. It will be priced at $169, or $229 for the family pack, as it is mostly aimed at consumers still on Tiger. There are no announced plans for a Snow Leopard upgrade Mac Box Set.
http://www.apple.com/pr/library/2009/06/08macosx.html
For you, it looks like it may still be about the same price to go with the box set or the individual apps.
iLife family pack = $99
+
iWork single user = $79
+
Snow Leopard family pack upgrade = $49
=
$227
So for $3 more, you get iWork for every family computer as well.

Tom,
Thanks for the quick answer (and doing the math). I googled around, but didn't think to look at Apple's PR site.

response to Brian re: Mac Mini & Aquos
I use Monoprice's DisplayPort - HDMI cable and still had to struggle with overscan/under-scan problems. Friendly advice - when using Mac Mini via HDMI - use "Dot by Dot" setting under View Mode on your TV remote. This will solve the problem!
