If you already own Suitcase 9.0.1, there is no reason to upgrade as the new version number is only to reflect the new naming scheme. I have Suitcase 8. A Power Macintosh or equivalent. MacOS 8.5 through MacOS 9.1. The Suitcase 9 XT requires Quark XPress 4.03 or higher.
Upgrades are available from Quark .
Suitcase 9 MenuFonts requires Adobe Type Manager version 3.8 or higher in order to render Type 1 fonts. If you are using MacOS 9, ATM 4.5.2 or higher is required for smooth rendering of PostScript fonts, whether you are using Suitcase or not. ATM did not ship with MacOS 9, but is available on the Suitcase 9 CD-ROM and for download from Adobe . If you own Extensis Suitcase 9 you only need the free version of ATM 4.5.2 or higher to display. After upgrading from Suitcase 8 to Suitcase 9, I have no fonts in my Suitcase 9 application.
