30-Day Trial Customer for Bitdefender FAMILY PACK 2020
Installed Bitdefender 2020 Version 8.1.6.3 on two MacBooks running Catalina 10.15.5 + Supplemental Security Fix on June 2, 2020. Both installs got very confused concerning required "Full Disk Access" permissions. The MacOS install video says that BDLDaemon, BDCoreissues, bdagentd, and Antivirus for Mac require "Full Disk Access", but following the install instructions didn't walk through that for all four. The install claimed to have succeeded, but the Safari browser extensions could not be installed and the product didn't work.
The workaround was manually to unlock "Full Disk Access", set the permissions, and relock. After that, all OK.
PS: I understand the warning about "not compatible with a future MacOS release". Not a concern.
