Hello, Yesterday I bought a new PIXMA MG5420 printer/scanner/copier/DVD-print All-In-One. Trying to set it up today to use with my 2009 MacBook Pro 15", running OS X 10.9.1 at the moment. Everything seemed OK until I tried to use the Canon-furnished setup CD-ROM which would quit with an 'internal error' message after maybe 12-24 M of 436 M downloaded. After about 5 tries, gave that up and, from the Canon USA site, downloaded everything listed (Drivers, software and more) that was OS X 10.9 compatible. Was able to install only 6 of the 8. I'm assuming the Canon setup DVD, U1.1 QH7-6333-01 is just too old, but that I haven't loaded enough software yet by going direct to Canon On-Line. Any help and guidance you can provide will be much appreciated! rackboy3
Careful inventory of dmgs. revealed items missing - downloading & installation fixed the problem.
