The MacMedics List Of Known Apple Mavericks Issues

We’ll be posting our list of OS X 10.9 Mavericks issues as they pop up. We’ll post to our Twitter account whenever we update this page.
Update 10/25/13: The upgrade for the most part has thus far been “friendly” towards design apps. Adobe confirms compatibility with CS 6 and later. With prior versions we haven’t seen any issues yet either.
We are however receiving calls from clients who are experiencing problems effecting other applications, multi-function printers, and syncing data between devices.
In the meantime, as tempting as it is, we are recommending that Mac users hold off on upgrading mission-critical workstations.
1. There are currently no available Mavericks (OSX 10.9) drivers from Canon for the Canon iPF650
2. Apple Mavericks OS X 10.9 and Western Digital – Data Loss – Some of the software that was bundled with external Western Digital hard dives could cause data loss when Mavericks (OS X 10.9) is installed. https://macmedics.com/?p=2812
3. Mavericks breaks some USB video adapters.
4. Adobe software issues: Adobe is aware of some issues when using Creative Cloud, Creative Suite 6, or Adobe Acrobat products with Mac OS X 10.9 (Mavericks)
In some instances, the Adobe Creative Cloud desktop application may encounter an “incompatible software error” and requires a workaround to be compatible. For the latest information visit: http://helpx.adobe.com/creative-cloud/kb/incompatible-software-mavericks.html
