Little known fact, but you can scan using macOS's Preview. Just do File->Import from Scanner.

Scans from my Brother something-or-other with no apps or drivers whatsoever directly to PDF, over Wi-Fi. Perfect.

MacOS also has an Image Capture app that's explicitly made for scanning.

The only real problem I have with it is that it wants to do a preview scan first if you used the scanner bed last (as opposed to the document feeder) and it freezes it's interface while that's happening.

TIL. I’ve always used the included Image Capture app for all my scans.
