Having a bit of a change around during the hols, and I
need to link up a computer (Mac Mini) to a USB DAC 5
metres away.

The usual length limit for USB is 15 feet - close enough to 5 meters.

The maximum length for USB1.1 devices is 3 metres. My USB DAC is a
USB1.1 device and not USB2. Whether the cable limit refers to the host
adaptor or the client device I don't know.

It's the maximum total length of unboosted cable permitted between the
master and slave devices before the signal needs regenerating. You can
daisy chain a number of 3 metre segments, provided they are all linked
by active connectors, but the active connectors in the chain must be
there, and no more than the maximum permitted distance apart.

Example:-

PC (Master) --- 3metres --- Active connector --- 3metres ---- DAC (Slave
device)

Should work

PC (Master)--- 6 metres --- DAC (Slave device)

Probably won't.
