System Information
Operating system: Darwin-17.7.0-x86_64-i386-64bit 64 Bits
Graphics card: NVIDIA GeForce GTX 980 Ti OpenGL Engine NVIDIA Corporation 4.1 NVIDIA-10.33.0 387.10.10.10.40.140

Blender Version
Broken: version: 2.91.2, branch: master, commit date: 2021-01-19 16:15, hash: 5be9ef4177
Worked: Same problem showing in 2.83.12

Short description of error
When multiple node are attached to a texture a point is reached where the texture display turns pink (as if there was a missing texture). Switching off a node returns the display to normal.
As an example, an object with 3 textures applied and nodes to control mixing. Once the third texture is attached I get the pink screen. Unhooking a channel in any of the three textures (ie. normals, displacement, etc.) allows the correct display (less that channel). Display is normal in Cycles.
I'm seeing many Mac users with the same problem in a discussion panel on CGBoost

Exact steps for others to reproduce the error
Default start file. Three textures applied with two Mix Shader nodes. In Eevee display is pink. disconnect any one channel from any texture and texture displays.
Example file uploaded. node example.blend

This is because OSX has poor Opengl drivers that allow only 16 textures to be used at the same time. But EEVEE uses a lot of them for its own purpose.

So it's a limitation of the platform.

However, this limitation would be lifted after the vulkan port.
