Areca MacOS build-in driver is a kernel extension. But Macs new macOS no longer supports kernel extensions driver update for tape support function in areca new driver. You need to change the ARC-8050-T3U-12E (ARC-1886 RAID adapter) device ID using ARC1886BOOT.86 code, so macOS will load the manually installation software extension driver downloaded from Areca web site instead of existed kernel extension driver similar as M1 Macs.
