At a case presentation meeting this week we had two MacBook Pro 14inch laptops with up to date Sequoia 15.0.1 macOS and neither would recognise any of the USB flash drives presented - a third person confirmed that their MacBook Pro has also recently stopped recognizing usb flash drives. Is this a bug in the recent macOS updates?

As to the USB flash Drive issue
Refer to Link Below from Apple on this very topic
If your Mac asks you to allow an accessory to connect - Apple Support
Excerpt from link above
When you use a new or unknown USB accessory, Thunderbolt accessory, or SD card with your Mac laptop with Apple silicon and macOS Ventura or later,
Welcome KendrewS
Sorry this is happening
Fat32 Flash Drives used only macOS
Or Fat32 Flash Drives that jump from MS Windows back to macOS ?
It remains that on at least 2 Laptops I use with macOS 15.1.1 Sequoia
When a New or Unknown new Flash Drive formatted in exFat, Fat32, Mac Extended Journaled /GUID or APFS / GUID
They have always presented as per below
So the assertion " Is this a bug in the recent macOS updates " seems unfounded
Thanks PRP_53.
On one occasion I got the "allow to connect" message, clicked on "allow", or whatever that option said, and the device promptly disappeared and did not open the drive. Mostly, though, when the device is connected there is no sign of it anywhere in Finder nor the desktop (as it is set to show). Like I said this is happening on a number of MacBook Pro's owned by a variety of people, so it seems to me to be a software issue and not a device issue.
Also, my external SSD hard drives will connect without any problems, it seems to be only Falsh Drives which will nto connect (they are mostly formatted as FAT32).
Thanks PRP_53. This is exactly how my settings are. Still having no joy in recognising any flash drives.
For the record, I have not made any assertions, it was a question as to whether this could be a bug - just hoping that if otehrs are also having a similar problem, maybe someone from Apple can look into it?
