Upgraded to 10.6.3 from 10.5.8.
Uploaded a 10.6.3 upgrade (from 10.5.8) to my iMac 27", 3.06 gHz Intel Core 2 Duo. Was unable to upgrade to 10.6.4 and now all my QuarkXpress 8.8 files and server files are not visible and cannot access printers anymore. There is 4 GB 800 mHz hard drive.
Any ideas? Thanks.
iMac, Mac OS X (10.5.8)
