    I tried using Unity 2021 on an Intel mac and this issue locks up the entire OS.

    A fix can't come soon enough, only Unity 2019 is safe for Intel Mac users right now.

    This is a serious issue for me in 2020.3.x

    It's not just the editor, mac builds suffer too.

    Unity Editor is next to unusable. I am forced to do builds every now and then just to check if performance is sufficient. Metal users are 3rd class citizens I guess. This issue exists since 1,5 years. No professionally to be found here.

    Is this somehow still related to this? https://issuetracker.unity3d.com/issues/mac-performance-regression-in-editor-ui?page=1#comments

    I updated to 2021.2.17f1 from 2021.1.28f1 and the performance regression is appalling. Drag and dropping can take seconds to trigger or even stay there waiting for ever for a next UI input event to finalize it.

    Got it on video

    This doesn't seem to be ever fixed. Unity support plays three monkeys when asked.

    2021.2.15 and still no fix ? Not even a single comment on the issue and no ETA. Seriously ?
