TS3540 iTunes 11.0.4 (62) Fails to recognize iOS devices - Fall back to previous iTunes

Question

Sometimes Apple releases an application that has a serious flaw in it like the new iTunes 11.0.4 (62) which is not recognizing iOS devices. There are over 56,000 users who have reported this in many threads on the Apple discussion support forum.
There needs to be an easy way in the MacOS (and iOS) to fall back to the previous revision of the software. Otherwise we can't trust the automatic updater which means we can use auto-update which means when new software comes out we'll wait for months to see if problems are reported before daring to upgrade which divides the Apple ecosystem and increases support loads on Apple which costs Apple's investor's money. All bad things.
I should be able to simply REVERT to the previous version of iTunes which worked perfectly fine.

Answer 1

This seems to have fixed the issue: on your desktop, hold down the [OPT] key and click on "Go" in the menu bar; holding down the [OPT] click on Library, find Preferences, and then delete all the files that start with "com.apple.itunes.XXXX.plist" where the "XXX" is whatever other things may exist - as long as they end in "plist". From my experience, preference files are rebuilt by the system after the next restart, so you have very little worry of losing any important data; the worst that could happen )and NOT in this instance, but for other plist files) is that you may have to reset the application "preferences" again when you next start it up, to act or appear in a "preferred" customized way for you.
Once you delete the .plist files, empty the Trash, and either log out or restart the computer. Once you're back up and operational, start iTunes and your iDevices should reappear in the sidebar (if that's open) and/or at the top of the screen (if that view is enabled).
Hope that helps. It definitely fixed my problem!
