[swifty99]

Describe the bug
On Mac the sACN interface does not transmit on any interface but localhost
On Windows this works no problem

Tested and reproduced with sACN viewer on several machines.

To Reproduce
start QLC from scratch
define a fixture
connect the universe to interface
go

Expected behavior
E1.31 transmitts data

Screenshots

Desktop (please complete the following information):

WLAN/Ethernet interfaces tested

Additional context
Using sACN Viewer to test send from the same machine has no issues.

Please let me know if additional context is needed. Thank you.

I have prepared the proper entitlements here but I'm having difficulties in adding them to the bundle.
Apple is giving me a hard time in deploying QLC+ on Mac.

[mcallegari]

Please check the latest version
https://qlcplus.org/downloads/4.14.0/QLC+_4.14.0_arm64.dmg

thx, for getting into it.

It looks like it is crashing. I replaced the app and get the first selections screen. Whatever I am selecting nothing happens. Something I can try?

[mcallegari]

Please try again.
I have found an error.
Same download link.
Thanks

[swifty99]

it is starting again, however not sending data. (0 packets sent)

I have been trying to use LedFx with the python scan library. That fails too on more than one device. maybe related, binding several sockets to the same ports seems restricted recently.

thx

[mcallegari]

Can you please try one more time? Same download link.
The bundle is now properly signed. Let's see if entitlements are included correctly as well.

[swifty99]

the signing did work. Easy install. What do you mean with entitlements?

But still: loopback is sending packets, ethernet interface is not:

I also can replicate the problem under macOS 15.2.
Signing works for me too with the latest build.
I researched a bit about this multicast entitlement.
If I understand it correctly, Apple needs to approve this permission separately: https://developer.apple.com/documentation/bundleresources/entitlements/com.apple.developer.networking.multicast

"This entitlement requires permission from Apple before you can use it in your app. Request permission from the Multicast Networking Entitlement Request page."
