iTunes 4.7.1 (#3): Radio channel problem temporary; Crash when iPod is connected while iTunes is running: Potential fixes; more
Radio channel problem temporary Yesterday we reported on an issue where users were unable to access online radio stations after updating to iTunes 4.7.1. It now appears that this problem was temporary, and has now been resolved.
MacFixIt reader Doug Eldred writes: "I think the 'radio' problem was real and temporary. I too was unable to use several of the radio 'genres' (probably all of them, but I only tried one or two), but it's been fine since. Either it was a real but temporary outage, or it was a real but fixed problem. It was a one-time failure for me."
Crash when iPod is connected while iTunes is running: Potential fixes Yesterday we reported issues while connecting and attempting to synchronize an iPod with iTunes 4.7.1 -- specifically freezes in iTunes, or kernel panics.
In some cases, this issue may be resolved by deleting several .plist files from the ~/Library/Preferences directory while iTunes is not running. The files are:
- com.apple.iPod.plist
- com.apple.iTunes.eq.plist
- com.apple.iTunes.plist
After these files are deleted, re-launch iTunes and attempt iPod synchronization again.
Audio drop-outs with AirPort Express: Potential fix Yesterday we reported an increase in audio stream drop-outs when playing music through an AirPort Express.
Some readers have been able to solve this issue by changing the default channel for their AirPort Express Base station.
This is accomplished by opening the AirPort Admin Utility (located in Applications/Utilities), clicking the AirPort tab, selecting a different channel, then pressing the Update button.
MacFixit reader Larry is one reader who had success with this workaround:
"I had problems with the audio dropouts using iTunes 4.7.1 with all, or substantially all, tracks. I was able to eliminate the problem entirely by changing the channel on which the AirPort Base Station transmits, from the default (channel 1) to another channel (I used channel 6). Since I made the change, I haven't had any dropouts at all."
Installation fails when Applications folder is on separate partition MacFixIt reader Len Whyte reports an issue where the iTunes 4.7.1 installer fails when the user's Applications folder is located on a separate partition -- even if the partition carries the same path as the normal Applications folder on a standard Mac OS X installation (i.e. Macintosh HD/Applications].
Normally this set-up allows proper installation of applications that require the Applications folder to be in its standard location, but not so for the iTunes 4.7.1 installer.
Whyte writes:
"I have a separate, hard mounted partition for Applications. For some reason, although the paths are all the same, this causes this version of the iTunes installer to break. The Receipts package is generated, but the material isn't installed. It runs like lightning and indicates success, but doesn't do anything. Works fine on a machine where Applications is within the root partition."

As far as I know this has always been an issue with OS X. Some third party apps and most Apple apps have problems if they are not installed on the boot volume. This has varied from one version of OS X to another but there is sufficient inconsistency in the matter that I consider installing applications on a separate partition to be risky, with too many potential problems.
Of course, on older Macs the original hard drive may be insufficient as the OS and many applications have grown huge in recent years. And I once thought a 20 GB partition on a 60 GB drive would be adequate for OS X. I was wrong.
The best solution is to install a bigger hard drive and clone your present system to it. Make sure your OS X partition is larger than you ever expect to need because, chances are, you will need that space someday.
