when search anything on apple music, an error occurred. Try again!

You can try reinstalling the current version of iTunes from https://www.apple.com/itunes/download/ over the top of the existing one. Or see this guide to uninstall iTunes from a Mac: http://www.inforaid.com/how-to-uninstall-itunes-from-mac-os-x-best-method/ then restore one of these recent builds direct from Apple's secure servers:

See also Empty/corrupt iTunes library after upgrade/crash for steps to roll back to the pre upgrade version of your iTunes database if required.

See Empty/corrupt iTunes library after upgrade/crash for roll back advice. iTunes 12.5.1 was released September 2016, so you'd be looking for an itl around that time to put back in place. You can then scan the media folder for new additions to the library since then.

For whatever it's worth, I'm having this problem too, but was not the last time I used iTunes for anything a month or two ago. I just spent an hour on the phone with Apple support, got escalated to a "Senior Advisor". I ended up troubleshooting this quite thoroughly (in a former life I worked at Apple as a QA engineer... back when they actually had QA engineers...) and came to a pretty definitive conclusion - somewhere between iTunes 12.4.3 and 12.6.2, something broke with regards to Mavericks and searching local or Apple Music libraries. 12.4.3 works fine, 12.6.2 does not. During the call I was unable to fund this thread again to download a version in the middle, but I am doing so now. My memory is that 12.5.x also worked fine, but my memory could be wrong and now I'm going to verify that.

But definitely, there is an iTunes issue here. We took detailed system logs and uploaded them to Apple engineering, so someone will at least see this, though I frankly doubt any engineer at Apple will be willing to fix an obscure problem with an OS version many years out of date. Good to know though for anyone encountering this now.

For further information, I have now tested uninstalling and reinstalling iTunes versions 12.6, and 12.5.5 onto my Mavericks iMac, and both still exhibit the same problem. 12.4.3 however works flawlessly, so this is definitely an iTunes > 12.4.3 issue.

My only problem now, is that my existing 12.6.x iTunes .itl file of course can’t be read by 12.4.3 iTunes, so I effectively lose access to my entire library if I stick with 12.4.3. So it’s a question of be able to search, or use my library. Definitely a no-win situation.

I know Mavericks is hopelessly out of date, but there are a LOT of people still using it, so I seriously hope this can be addressed in an update soon.

Unfortunately, iTunes version 12.5 still has the same issue, I had to roll all the way back to 12.4.3 to be able to search. My "Previous iTunes Libraries" folder only had a single library in it, from 2013. It does load in 12.4.3 but of course is missing a lot of stuff since that's so many years ago.

Have the same problem, same OS, MBP late 2013.

So tired of Apple sw bugs, nothing runs smoothly.

Same problem, Mavericks 10.9.5 on iMac 27".

My Mac mini is running Sierra and I run Windows 7 elsewhere. I don't have a subscription to Apple Music either so I'm not really in a position to test otherwise I might give it a shot.
