> Adobe and Apple have worked closely together to test Adobe® Creative Cloud applications and Adobe Creative Suite 6 applications for reliability, performance and user experience when installed on Intel® based systems running Mac OS X Mavericks. (v10.9). All Adobe CC and CS6 products are compatible, but a few products require updates to the latest builds to work properly. Adobe Photoshop® CS5, CS4 and CS3 were also tested with Mac OS X Mavericks and there are currently no major issues known.
Good to hear. Normally, Adobe seems to be one of the companies whose software is not ready for the release.
