Yesterday, Apple made the Public Beta of OS X Yosemite available.
The current status of Reinvented Software apps is that they will run on Yosemite, but may not look very nice, there may be issues I don’t know about yet and it is unlikely much work will be finished on the apps before the Yosemite’s release later in the year, not least because iOS 8 is rumoured to launch a month beforehand, and so that takes priority (BTW, it’s great basing your work schedule entirely on guesswork).
One particular issue with Yosemite and iOS 8 that will affect Together users is iCloud. iCloud is undergoing significant changes on both Yosemite and iOS 8, and Together needs significant changes to keep working. There are even reports that just enabling iCloud Drive will stop syncing across all devices running prior versions of OS X and iOS, for example.
In short, if you run Yosemite, don’t expect anything to work, and don’t expect support or quick fixes for your problems. I simply do not have the time or resources to offer them. Thank you.
