System Information
Operating system: macOS-11.2.3-arm64-arm-64bit 64 Bits
Graphics card: Apple M1 Apple 4.1 Metal - 71.0.7

Blender Version
Broken: version: 2.93.0 Beta, branch: master (modified), commit date: 2021-04-19 10:12, hash: 6dffdb02fa
Worked: It's never been good on the Mac platform

Short description of error
When working in a heavy scene (the barbershop demo, for example), the UI will often "beach ball" or lock up for brief periods during an interactive denoise calculation. On a pc, these calculations don't appear to bog down the interface the way it does on Mac, even when only using the cpu. SHouldn't the expected behavior be that the UI remains responsive, even when the denser is active? The UI remains very snappy during interactive rendering when denser is off on the Mac.

Exact steps for others to reproduce the error
[Please describe the exact steps needed to reproduce the issue]
Open the barbershop demo, turn on interactive cycles rendering with OpenImage viewport denoising set to 1, then start tumbling and moving around in the viewport. Within a few moments, you will like start seeing the "beach ball" and the UI starting to hitch and lock up until the densoiser finishes its calculation.

Just an interesting note: Apple just submitted a patch upstream 16 hours ago to "Improve performance with large images."

Can you retest with a more recent version? As this seems to have been fixed upstream in OIDN v1.4.0.
