This is a narrow-interest post, but if you are affected I can all but guarantee you will appreciate it.
Many hospitals and healthcare delivery systems using Epic provide physicians with remote access to the Epic EHR. HealthPartners in MN, where my wife works does this.
The HealthPartners site recommends installation of "Citrix ICA Client" for Windows. It doesn't say what to do for a Mac. We've used the "Citrix Online Plugin" for Snow Leopard for years, but it's no longer supported. We uninstalled it.
So what should one do? Should one install, for example, the beta version of Citrix Access Gateway with 10.8 support?
Briefly - no. Download and install Citrix - Receiver for Mac 11.6 or later. Citrix has an abysmal web site, but it appears that the 'Access Gateway' product is largely obsolete. Receiver is a supported product and it worked with the HealthPartner's Citrix gateway.
It works, but that doesn't mean it's quality software. The installation failed from a User account, even after granting Admin rights. I had to uninstall and reinstall from an Admin account. (It's also possible that there were bits of old Citrix app remaining and the uninstaller cleaned them up -- but I'd unstable previously.)
