When running Mac OS, Tascam requires an Apple MacintoshPowerPC running Mac OS 8.6 or better,
and a USB port. Any Macintosh computer
with one or more USB ports running
Mac O/S 8.6 or later (check the
Web site for updates), or Mac OS X
10.2.3 or above.
Very early iMac computers may need
one (or more) firmware updates to use
the US-122. Which firmware update(s)
is (are) needed depends on which Mac
OS version is installed in the early iMac.
Apple provides details in Apple Support
Article #58174. PowerBook G3 Series (or later) with
built in USB (or using a 3rd party PCMCIA
USB Card) have been tested and
work fine. Additionally, older PowerMac
computers using 3rd party PCI-based
USB cards also have been tested and
work fine. Any iMac, G3 or G4 will
work fine as well. Mac OS versions earlier
than 8.6 do not implement full USB
support, and are not recommended.
Again, plenty of RAM and fast drives are
suggested.
