iTunes 12.7.2 crashes after update

Hmm, working for me on High Sierra. Reinstall the previous build?

Here are some recent builds of iTunes direct from Apple's secure servers in case you want to try working with an older version:

iTunes 12.6.3 can be installed over iTunes 12.7 if you wish to recover the app and tone management features that were removed in 12.7, however in general downgrading iTunes on a Mac is harder than upgrading or reinstalling. See this guide to uninstall iTunes from a Mac: http://www.inforaid.com/how-to-uninstall-itunes-from-mac-os-x-best-method/. When reverting to an earlier build you often need to restore an older version of the library database as shown in Empty/corrupt iTunes library after upgrade/crash or from another suitable backup such as Time Machine.

We disabled mDNS snooping feature at out enterprise wifi controller. Make same with domestic or less advanced wifi will be hard. Disabling mDNS service on the mac absolutely useless. iTunes will start but will not work.

I realise that some people have found other solutions to this, but it's still one of the top results for a search on the issue, so I wanted to add some findings of my own that aren't listed here.

I was experiencing this same issue, and by chance I happened to look at Notification Centre and discover that there's a new widget available, Now Playing, which is functionally identical to the iTunes widget I've been using before.

What I did was, with Notification Centre open, I chose edit, removed the iTunes widget and put the Now Playing widget in its place, now iTunes seems to be stable again. In addition to crashing I also had another issue, which was that my media keys weren't working properly for iTunes, swapping widgets resolved that as well.

In my case I updated from El Capitan to High Sierra (yes, yes, I'm a bit slow to update I know) so I assume the iTunes widget is obsolete now, and somehow has compatibility issues under High Sierra. Why it isn't uninstalled automatically in that case I have no idea, but it's working now so that's what matters.

Try a fresh install from iTunes - Download iTunes Now - Apple.

Solution here: Open Photo app first, then you can resume iTunes 12.7.2, it's workable for me.

We finally confirmed that problem is in mDNS/Bonjour. When network is broadcasting mDNS option "_airplay._tcp.local." iTunes is crashing. We disabled it until Apple releases the fix.

@pwmcheng, Do you have any airplay devices in network? If no, can you show screenshot of Tildesoft Bonjour Browser?

Resolved by restoring old backup files back to the time when iTunes 12.7.14 is being used.

Try downloading iTunes 12.7.2.60 from iTunes - Download iTunes Now - Apple. It isn't showing up in Software Update yet. I haven't worked out what it is supposed to fix, so it could be this. 😕

Somehow it is a network issue. When mac is not connected to the internet (in my case corporate guest wifi network) iTunes starts, but when connection establishes iTunes immediately crashes. When wifi is shared from the iPhone, iTunes is working without crashing.

One more thing, iTunes doesn't crash when mac connected via ethernet cable to the same network while wifi is turned off. But crashes on connect to wireless network. Ethernet has highest priority order in the list of network services.

Hmm, proxy server? I know that has been causing issues for iTunes for Windows users for some time.

Try to turn it off. Reconnect to the wi-fi. And start iTunes again. I'm curious will this work?

I have the same problem. When I have WiFi or Ethernet turned on, iTune crashes on startup. But when the WiFi or Ethernet is disabled, iTune comes up fine. I have tried the following steps:

• Reinstalled iTunes 12.7.2
• Reinstall iTunes 12.6.2
• Reinstalled High Sierra 10.13.2 Combo
• Restore several known working iTunes libraries from Time Machine backups

They all failed. I then call Apple Support and they said I need to do a clean install of High Sierra, removing all data. Which I can't believe will resolve the problem and I'm subscribing to Apple Music which I can't access. The following is my hardware config:

• Macbook Pro 13" later 2016 with touch bar
• Thunderbolt Display

The only difference between wired and wireless connection (I can remember) is mdns/bonjour broadcast which is present on the wifi and not present on the wire.

But this can only be tested next week...
