Thunberbolt ports
Hi
I moved my late 2015 iMAC temporarily out of the office recently and had to disconnect peripherals. Upon return I've found that neither of the Thunderbolt ports work, I've tried various external devices, they're not appearing in Finder (also means I can't run my 2nd screen). Never had a problem before and I've had the iMAC since 2016. Its running Monteray 12.6.2 but it was same on previous update.
Anyone know how I can fix this?
