Got a new MacBook Pro with the M1 chip and was surprised to find that Bitdefender worked quite well. In fact, even though it's running in emulation under Rosetta 2, it's snappy (more so on my older Intel Macs) and it immediately detected and removed test malware. There was a warning of a blocked extension during install (likely a Big Sur issue) but didn't seem to cause any problems so far. Hope to see an update down the road so it runs natively.
