[Gizmo - http://gizmo.web.id] Bugs & Fixes: Troubleshooting iTunes 11: The sequel

Troubleshooting iTunes 11: The sequel'

While iTunes 11.0.1 appears to have fixed most of bugs reported in the
applications initial 11.0 release (including those I covered in a previous
column), a few lingering issues remain.

AirPlay bug

One bug that continues to generate heat in Apple Support Communities concerns
AirPlay. Numerous users find that, after updating to iTunes 11.x, content
streamed to an Apple TV (or other AirPlay device) can stop playing unexpectedly.
This can occur as early as the middle of the first played song or as late as an
hour or more into a playlist or movie.

Evidence points to iTunes as the ultimate cause, as people report that the
symptom affects any and all of their AirPlay devices. As a few users pointed
out, media can stop playing if your Mac goes to sleep (duh!). However, most
users note that unwanted halts occur independent of sleep.

A usually successful work-around is to go to iTunes AirPlay menu and shift to
the Multiple, rather than Single, option (see figure below). If your AirPlay
device connects via Ethernet, another potential work-around is to switch from
the wired connection to a wireless one. This is reminiscent of a similar switch
that remedied an inability to install the Apple TV 5.1.1 update.

Shifting iTunes AirPlay menu from Single to Multiple may solve a streaming
glitch.On a personal note, I have had a similar problem with premature halting
of playlists in iTunes 11. However, it is not restricted to AirPlay. It occurs
on my Apple TV even when streaming directly from my Mac.

Hotspot bug

An iTunes-related Personal Hotspot issue dates back at least as far as iTunes
10.7. The symptom is a failure of the USB Hotspot option, when connecting an
iPhone or iPad to a Mac. Unfortunately, based on reports in Apple Support
Communities, the bug remains present after updating to the latest 11.0.1 version
of iTunes.

The most frequently recommended work-around is to use Kext Utility to replace
the currently installed AppleUSBEthernetHost.kext file (located in
/System/Library/Extensions) with a prior version as obtained from the web.
Precise details on how to do this can be found in another Apple Support
Communities thread. One further thread implicates iPhone Configuration Utility
as a co-conspirator. Postings here advise deleting the Utility (as well as its
receipts file, accessed via Terminal) before removing the aforementioned kext
file.

Although the fix should allow USB tethering to work again, it is not an ideal
solution. First, the next time you update iTunes and/or OS X, the replacement
file may get wiped out by the newer install, with the symptom returning. Second,
any custom modification to the content of the Extensions folder is risky. Older
replacement files may turn out to be incompatible with other aspects of the
current OS, resulting in unpredictable problems separate from whatever you are
trying to fix. However, until Apple addresses the ultimate cause, kext
replacement may be worth a try. Just make certain you have backup copies of any
removed files, in case you need to do a restore.
