Has anyone else had issues after installing the latest security update?
I lost connection with my Powerlinc 2413U last night, and nothing that I tried could get it to find the USB port. (It's a new unit - a couple of months old.) Unplugged for 10+ secs, changed USB port, power outlets and USB cable.. nothing. I didn't do the factory reset - that was my last resort and I wanted to check for other culprits before resenting every single link.
There had been a momentary power cut and surge earlier in the day, but that was 5 hours before the log showed its first problem. But it did coincide with restarting after the OS security update.
Ran the recovery program and reinstalled the OS from the last time machine backup before the update, and a mere 3.5 hours later, all is as well. Coincidence? Or could the update have reintroduced some USB instability?
