First this thread was started in 2019 and treats the legacy versions of EN. These versions are deprecated since October 2020. If they fail, they fail. EN is not doing anything about them. This means they are not actively damaging anything either. If these legacy clients become unusable, this happens because of other changes, like OS updates. Second all inquiries about the new Mac clients should be posted in the right subforum. This forum here is dedicated to the legacy clients, and not the right place for the new version. The new version requires MacOS 10.14 Mojave as minimum system requirement.
