Touchdesigner crashing after Sequoia 15.4.1 update

Bugs
1

Hello, after I updated my macOS to Sequoia 15.4.1, while it was working fine before that. TouchDesigner is crashing on launch due to a segmentation fault (SIGSEGV)

The crash happens right in the main thread during app startup—before it even draws the UI or loads user preferences. There seems to be a memory access error —something in the app is referencing an invalid or uninitialized memory address.

I bought Touchdesigner commercial in 2024.

Please help, as I am on a deadline and need to use Touchdesigner ASAP. :frowning:

Hi @kirrieswensii,

can you let us know what TouchDesigner version you are using and what your hardware is?

Definitely!

Here is some info:

Touchdesigner version:
I bought it in March 2024, so I am assuming 2024 version, commercial license.

Hardware:
MacBook Pro, 16 inch, 2019
Graphics: AMD Radeon Pro 5300M 4GB
Intel UHD Graphics 630 1536 MB
Memory: 16 GB 2667 Mhz DDR4
macOS: Sequoia 15.4.1

Before the update it was working just fine, so wondering if this update has to do with it.

Thanks for quick response!

Hi there,

It seems to be working again. It just needed a update again. Will check-in from time to time for new updates.

Thank you for the quick response and thinking along.

Best,
Kirsten.
