Anyone know how I can fix this?
Thanks!

This was fixed in an updated zlib version that VTK originally included in the 9.4 release (see linked commit below). It resolved issues with newer clang versions as you’ve experienced. If possible, I would suggest using VTK 9.4.2 instead of 9.3.0rc1.

Unfortunately build of VTK 9.4.2 also fails on macos sequoia, for a different reaon - documented here

Anyone know when this VTK bug will be fixed on MacOS Sequoia?

This is already fixed in master.

Sweet, master builds on Sequoia! Does anyone know when these fixes will be incoporated into a release? (My app requires VTK 9.3+ on MacOS Sequoia, would be nice if it used an official VTK release)

It will be available in the upcoming v9.5.0 release.
