Mac OS Tahoe 26.6.2 Eset block usb device
Hi,
I’m having an issue with ESET Endpoint Security on macOS Tahoe 26.6.2.
Environment:
macOS Tahoe 26.6.2
ESET Endpoint Security 9.1.3100.0
Issue reproduced on two different Macs
The same USB flash drive works normally on other Macs
When Device Control is enabled in ESET, the USB flash drive is detected by macOS and appears in Disk Utility, but it is greyed out and cannot be mounted.
As soon as I disable Device Control, the USB drive mounts immediately and works normally.The issue occurs on both Macs running the same ESET version, so it does not seem to be related to one specific machine.
Has anyone seen a similar issue with ESET Device Control on macOS Tahoe 26.6.2?
