I’m using easel on a MacBook Pro - and have downloaded the latest driver as suggested by you - but my computer tells me it can’t install it because the new driver ISN’T FROM THE APPLE STORE. Can the driver be put on the Apple store or does the answer lie in my computer settings ?? I’m not stuck at the moment, but if and when you delete the current driver I’m going to be stuffed ?!
If you right click on it and choose “open”, you should be able to bypass that Gatekeeper check.
