Ask TUAW: Recovering video files, moving from an old Mac to a new one, MobileMe Sync and more
Welcome back to Ask TUAW, our weekly Mac troubleshooting Q&A column. This week we've got questions about recovering video files from a corrupt SDHC card, transferring files from an old Mac to a new one, MobileMe sync, virtual machines 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.
Matt asks:
I recently shot video with a camera that records it to an SDHC card. Unfortunately, that card is now corrupted and when I try to download the video to my computer, it doesn't show up. How can I recover the video from the card?
I know how you feel because this exact thing happened to me recently. We shot a bunch of great video interviews for another site I work with, and one of the SDHC cards became corrupt. Fortunately, all was not lost but recovering the video, at least for me, was a two step process.
This is the method that worked for me, even though there are probably other tools available; I was under a deadline and needed to get this worked out fast so looking for the best free apps or the best deal wasn't an option. However, it did work and all the video was recovered with no loss.
So, one step down and one to go. As I stated previously, I was under a deadline so I didn't search endlessly for a tool to convert the recovered files to a format iMovie could recognize. The tool I found was iSkySoft's Video Converter ($35.00) which took the files and converted them to Quicktime easily and flawlessly. Sure, the software cost money, but in the end it was a small price to pay to recover hours of video interviews we could probably never have shot again.
David asks:
I recently purchased MobileMe to sync all of my information between 15" MBP, iPhone, and the web. Everything is working fine, except on my iPhone I have duplicate copies of everything. How do I fix this?
The easiest way is to do a one time wipe of your IPhone's MobileMe data (Address Book and iCal Info) and have that data replaced completely with the data on your Mac -- provided the data on your Mac is the most recent and accurate. To accomplish this, select the appropriate check box in iTunes while your iPhone is connected.
Find that box when your iPhone is connected by clicking the "Info" tab and then scrolling to the bottom under "Advanced." There check the boxes next to the data you want to replace on your iPhone. On the next sync your iPhone's MobileMe data will be replaced with that of the data on your Mac. Once all your devices have the same data, they should hopefully sync up normally from that point forward.
Joe asks:
What's the best way to transfer my old data on my old MacBook to my new MacBook Pro without erasing new software on the MBP like the new iLife suite?
The best way to accomplish this is by using Apple's included "Migration Assistant." This tool, located in /Applications/Utilities, comes with every Mac sold and is a great way to take date from an older Mac and move it to a new one -- particularly if both Macs have Firewire ports and the old one can support Target Disk Mode. If one or both Macs don't have Firewire, you can still use Migration Assistant via Ethernet, it will just be quite a bit slower.
To use Migration Assistant, launch it and follow the prompts until you get to the point of selecting what files, folders and other things to migrate from one Mac to another. Then, simply deselect the "Applications" choice and the Apps from your old Mac won't be transferred to your new one.
Anthony asks:
I have a first-gen Intel iMac and I'm wondering if it'll be compatible and worth it to get Snow Leopard. Really wish there was some software to check stuff like this to simplify the whole process.
According to Apple's stated requirements for Snow Leopard, your Mac should be able to run the next version of OS X just fine. However, due to your Mac's graphics card, you won't be able to take advantage of one of the newest and coolest features of Snow Leopard, Open CL acceleration.
This feature allows the OS to make the graphics card handle more tasks and thus results in speedier overall performance. Sadly, your Mac doesn't sport the necessary card so your Snow Leopard experience will be less than optimal. Still, you will be able to run it and take advantage of many of its other features and improvements.
With the given limitations, deciding if the upgrade to Snow Leopard is "worth it" is up to you.
ophiucus15 asks:
I use an early 2009 24" iMac, and a late 2007 13" MacBook running 10.5.7. My question involves a 1TB Time Capsule and VMware Fusion. I was wondering if it were possible to install a Vista virtual machine on a 100GB external hard drive and connect it to the Time Capsule and access this virtual machine wirelessly with either of my Macs?
That's a very interesting question and one that I've been asked a few times before. In theory there should be no reason this won't work. As long as the drive where the Virtual Machine is located is mounted on the desktop of the computer you are trying to run it from, it should work. Also, you can create an alias of the Virtual Machine in the folder where it should reside locally on your Mac. For VMWare, that's usually in your user folder inside the "Documents" folder.
However, keep in mind that it will be much slower than what you could expect from a locally available Virtual Machine. This setup is also not recommended by VMWare, which they advised me during my discussion with them about this question, so use this setup at your own risk. If you do decide to use it, let us know how it goes in the comments.
As a precaution, you may want to back up your virtual machine on a relatively frequent basis.

You know, tapes don't usually have this problem and are an instant backup....

Tapes? Instant?
Jordan said 10:40PM on 8-12-2009
Yeah, Instant, as in you record it in real-time just like you do with SD cards, and then it's there until you record over it. Tapes are cheap enough to throw on a shelf as backup.
Yeah, you can't just drag and drop, but by the time you convert all those files and get them into iMovie (really? iMovie?) you could have just used a tape, which is generally regarded as higher quality anyways.

That MobileMe sync advice is wrong. What is happening is that the duplicate contacts are coming from both "From My Mac" AND from MobileMe. What he needs to do is to go to System Preferences, select MobileMe, choose the "Sync" tab, and make sure that Contacts, Calendars etc are checked. Now, connect the iPhone to the Mac, go to iTunes and choose the iPhone, and make sure that Contacts, Calendars etc are NOT checked.
In this way, when any changes are made on the iPhone OR or on the Mac, it gets synced with MobileMe (which is the cloud). The updates are then pushed onto the appropriate device.

You'd think writers for an Apple blog would know that. Geez. What's up with that TUAW?
Sidenote: I hate when MobileMe overwrites my contacts and adds double last names (I write the contacts full name in the first name space to avoid searching contacts via last name). It always re-syncs and comes out John Anderson Anderson. Ugh

Good catch. I was having that issue for a while until I figured that one out. What took me longer was when I thought that iCal was not syncing from my iphone. I was actually viewing the iCal on my iphone under the "All on My iPhone" instead of "All .mac". Items created on the "All... iPhone" do not sync with .mac. Be sure you go back to all calendars and check this out because it stumped me for weeks. It seems very redundant to me to have this option in your calendars - I guess that's why I missed it.
GlennAC said 2:18AM on 8-16-2009
Here's another way to look at it.
As MobileMe is setup now, there is the distinct possibility that new data can enter your syncing data chain from at least 3 sources.
Your Mac at home.
Your MobileMe web interface.
And your iPhone.
With this setup, it is best to have syncing taking place along one continuous line of sources with 2 established ends, rather than a circular daisy-chain of sources. Otherwise, you have the potential of creating a conflicting loop of information - or, as in the case of the original poster, duplicate contacts and calendars. So imagine it this way...
Good:
Mac MobileMe iPhone
Bad:
Mac MobileMe iPhone Mac MobileMe iPhone Mac MobileMe iPhone Mac MobileMe iPhone...etc, etc, etc.
That is why it is not a good idea to have your phone syncing Calendars/Contacts both via MobilMe AND via iTunes syncing simultaneously. So either uncheck these sync items in iTunes "Info" tab, or turn OFF the syncing of these items in the iPhone's Settings.
Cheers!

Probably a question that a few people have, and it's probably simple, but I'll ask anyway:
I have a unibody MacBook with Leopard (included) and iLife '09 (upgraded from iLife '08). I'm hoping to install Snow Leopard on the day it's out, however I want to do a *clean* install instead of an upgrade of the OS.
But I want to keep all my current data, music, programs, settings, and so on.
Am I right in thinking that if I use Apple's Migration Assistant on Snow Leopard that it'll transfer all my old user account data (without losing anything) from a Time Machine backup? I can cope if an application here or there breaks, as I can reinstall them, but I'm just wondering if doing that will allow me to keep all my existing data, while still having a clean install of the OS?

Hill said 3:28PM on 8-12-2009
You can do an "archive and install", which moves all the old system files to a "previous system" folder, does a clean install of the new os, and retains your settings, files, applications, etc.
Essentially, it is a clean install and a migration without having to use a second computer or a time machine backup.
It's also the best way to do every os upgrade.
GlennAC said 9:47PM on 8-12-2009
William, actually, if you go the "clean install" route (aka "Erase & Install"), near the end of the installation process, the SL installer will ask you if you have user data you would like to migrate over to the new environment. Say yes and choose "From a Time Machine backup". It will then walk you through the process.
So you won't have to manually launch Migration Assistant since the feature is built into the OS installer already. Bear in mind as well, that this can be done before you create a new user account on the Mac. So you won't be stuck with user accounts you don't need. Cheers!

Cool, thanks for the tips! :)

David:
Also make sure that you don't have iTunes set to sync with your iPhone. Originally, syncing with Mobile Me disabled syncing with iTunes, but since iPhone 3.0, you can sync over the air with Mobile Me AND iTunes, so if you're syncing the same information from two sources, it will lead to duplicate entries.
ophiucus15:
One thing to add, make sure you DON'T try to run the virtual machine on more than one computer at the same time. All sorts of bad things could happen if you do :)

get an airport express. it will act as a kind of bouncer.

I have a question regarding migration too. I want to do a clean install when Snow Leopard is out to trash things I don't use out but the only thing bothering me is Keychain, as I rely heavily on it. How do I backup and restore my keychain?
Reply
GlennAC said 10:10PM on 8-12-2009
How do you backup your data? Do you use Time Machine? Perhaps Super Duper or Carbon Copy Cloner? If so then those will likely contain a copy of your Keychain. Migration Assistant can pull your data from these sources and restore your settings. Just ensure you have made a fresh backup just before you install Snow Leopard. Cheers!

This "Then, simply deselect the "Applications" choice and the Apps from your old Mac won't be transferred to your new one." is an unnecessary step. I used Setup Assistant (aka Migration Assistant) last night to move settings, etc., from my old MacBook to a new MacBook. My experience agrees with this http://en.wikipedia.org/wiki/Migration_Assistant_(Apple) that the tool is smart enough to not override standard Apple software — even with that Applications box checked — because it assumes that the new computer is at least as up to date if not moreso than the old Mac.

I recently upgraded from a black MacBook to a 13" MBP. I had iWork '09 preinstalled.
I used Migration Assist. to move my data, and it did basically what you said--it did not overwrite the preinstalled iWork. However, now I have a copy of iWork '08 & a copy of '09 in my apps folder. Can I use something like AppCleaner to remove '08 without borking '09?
Heimbachae said 2:34PM on 8-12-2009
Here's a good one. I have a mid 08 macbook (white). When I bought it I wasn't thinking I would need a DVD drive so I opted out of it. Now that SL is coming out I'm like OH SHAP!? So here's the question, is there a dvd player attachment I can plug in USB that'll work as a normal player or is it simpler to find an internal drive and gut it myself in the hopes that it'll work???
