Amplitube 5 crash on macOS Sequoia while idle

Hi everyone,

I’m running into a strange issue and was wondering if anyone has seen this before.

My setup:

  • System: MacBook Pro M1 Max, 64 GB RAM
  • OS: macOS Sequoia 15.7.3
  • Software: Gig Performer Pro 5.1.6

Here’s what happened: This morning, I opened my GigFile and was just playing a piano plugin in a single rackspace. Everything was working fine. I took a break for about an hour to grab a coffee and work out, leaving the Mac untouched.

When I came back, I was greeted by an “unexpectedly quit” error message. Everything was stable when I left it, and I’ve never experienced Gig Performer crashing while sitting idle like this, without any MIDI input or user interaction.

Any ideas what could have caused this? Could it be a background task in Sequoia or a specific plugin power management issue?

Thanks for your help!

Can we see the crash report?

Yes, of course.

Did you get this crash report from the console application?

Yes. But I have to sent the report to my Windows PC, so Windows translates it wrong.

My KI analyzed the crash log and it looks like AmpliTube 5 is the culprit. Specifically, the crash occurred in Thread 2185 within a NSURLSession delegate call:

Thread 2185 Crashed:: Dispatch queue: com.apple.NSURLSession-delegate
0 libsystem_pthread.dylib 0x18572a364 pthread_mutex_lock + 12
1 AmpliTube 5 0x713d59ef44 juce::Thread::signalThreadShouldExit() + 76
2 AmpliTube 5 0x713d5ad708 juce::URLConnectionState::didComplete(NSError*) + 80

It seems like AmpliTube tried to perform a background network task (likely a phone-home or update check) which triggered a segmentation fault in the JUCE framework while GP was idle.

One more thing: All my plugins, including AmpliTube 5, are fully licensed and activated. I’m a bit surprised by this background network activity since I’m not using any cloud features or the Custom Shop at the moment. I usually keep my Wi-Fi on at home for emails, but it seems AmpliTube’s background tasks are conflicting with the system.

Has anyone else encountered stability issues with AmpliTube 5 on Sequoia? Is there a known workaround, or should I reach out to IK Multimedia support?

Definitely reach out and send them the crash report.

I’ve seen a couple of reports of Amplitube 5 crashing.

What is KI?

Doesn’t “look like” - it’s 100% the culprit

Yes, and with 4 and with 3 and on every version of macOS — I won’t use that product for live performance.

Please do -

“KI” is german for “künstliche Intelligenz”. In English it is “AI”? I use Gemini.

Until now I had no problem with amplitude, but it is not important for me, I have tried a guitar rackspace from the GigPerfomer YouTube Channel.

Thank you for the quick answers!

Are you using ToneNET? Unless you’re buying upgrades or downloading presets, regular Amplitube is an offline app(once authorized). I use it almost exclusively for electric guitar.

No, I don’t use ToneNet. I reach out to IK Multimedia Support. According to my macOS crash logs (.ips), the culprit is a segmentation fault (EXC_BAD_ACCESS) triggered by a background network task. I will ask, whether Amplitude “phones home” or not.

I run Little Snitch on my Mac to block all attempts to make an outgoing connection.

I’ve also ruled out Amplitube for live use due to intermittent crashes on my studio Mac. The only IK plugin I use live is B3-X which is CPU heavy but stable for me

Nice!
