I'm a CC user in South Africa with p poor internet access. I updated PS, LR, Bridge, Muse and the Cloud Updater this yesterday.
I'm running on a Mac Pro. Absolutely no problems at all. Up and running importing images from a week shooting in the mountains. Processing in LR and PS.
Nice enhancements to LR. Loving the improvements to PS Heal and Spot Heal tools. A big productivity improvement for me and since that's how I earn a living I'm quite happy.
