HowToFix: Time Machine Error “Image of Sparsebundle already in Use”

Apple Time Machine & Time Capsule prove to be a boon for backup-dorks. And I think most of us belong to that species ;-)

Most of the time TimeMachine works well in the background. The only point you may recognize it is the temporary performance loss if the backup is running.
But yesterday, nothing worked any more: Time Capsule reported an error:

“Time Machine Error – The Backup disk image „/***/***/***.sparsebundle“ is already in use.”

Problem: Time Machine and the connected Time Capsule assume, that there is a backup process still running. In my case, a cold (but necessary) restart of my Mac was the reason for the confusion.

Solution: Unfortunately a restart of my Mac did not help. The problem is the Time Capsule itself, which has to release the established connection. You can fix that problem with the AirPort Utility under Programs/Utilities. The brand new AirPort Utility Version 6.1 has only one function you can use: The restart of the Time Capsule. But that did not help in my case. Weird but true: the old AirPort Utility Version 5.6.1 comes with much more features … especially “Disconnect all users …”. This is exactly what we need to solve our Time Machine error! So you just need to open the 5.6.1 version of the AirPort Utility, open the Time Capsule with a double click and open the tab “Disks” and press the button “Disconnect all users …”.

In order to solve the problem like I described before, I had to work around an other problem: How to install the old AirPort Utility version 5.6.1 on my Mac running OSX 10.8 Mountain Lion?! The old AirPort-Utility version works well under 10.8, but the installation routine will not allow to install it. Luckily, Frank Tisellano helps us out with am Automator workflow to extract the App from the installation bundle. In my case I had to open the “AirPort Utility Extractor” Skript in Automator to run the commands in the terminal manually.

I hope, that howToFix saves one or the other some time …

iOS application icon naming conventions

A short reminder on how to name your iPhone / iPad app icons properly. Sure, you can always specify those names specificy in the application info.plist. But why not chose convention over configuration to make life easier ;-)

Icon.png (required)
# 57x57px ... standard iPhone icon
Icon@2x.png (required)
# 114x114px ... retina display iPhone icon
Icon-72.png (required)
# 72x72px ... standard iPad icon
Icon-Small.png (recommended)
# 29x29px ... standard iPhone Spotlight search icon
Icon-Small@2x.png (recommended)
# 58x58px ... retina display iPhone Spotlight search icon
Icon-Small-50.png (recommended)
# 50x50px ... standard iPad Spotlight search icon

Just drag the files into the “Supporting Files folder” within Xcode and allow Xcode to copy the files into the proper directory of your app.
If you also want to adhoc distribute your app – like, in beta testing – you should also include the following iTunesArtwork-file in your source. If you want it to render with the shiny Apple effects in iTunes you need to provide a JPEG file, if it should be rendered untouched just use a PNG. The iTunesArtwork file must not have a file extention:

iTunesArtwork
# 512x521px ... iTunes icon used with adhoc distributions

And don’t forget to exclude the file in your iTunes-Connect distributions to the AppStore. There you upload the PNG file separately within the upload process in iTunesConnect!

Hope this saves some time ;-)

Video of the special event: A celebration of Steve’s life.

Apple just published the video of the tribute to Steve special event at the Apple Campus on October 19, 2011. So kind, that the Apple folks are sharing the event with us. Thanks. It’s really moving.

Picture: Apple

Stay Hungry, Stay Foolish … RIP Steve Jobs


Thank you for so much, Steve.

I was deeply moved by Your commencement speech in Stanford as I am when I watch it today …

“Let’s talk iPhone” … 4s Apple Special Event Video Stream


Sure, it’s not Steve Jobs presenting on this special event … but I think the mixture of Tim Cook, Scott Forstall, Eddy Cue and Phil Schiller giving the presentation works out quite well. But see it for yourself by watching the official video-stream from Apple about the iOS 5, iCould, iPhone 4s, Siri & all the other details.

P.S. Hope Steve Jobs health recovers!
