Lately I've been receiving notices that certain software, including Chrome Remote Desktop, will no longer support Mavericks. Back to My Mac never worked and I can't SSH in, but Chrome Remote Desktop works great and the performance is admirable given the relatively slow Internet bandwidth of the remote machine. I log on to the machine remotely using Chrome Remote Desktop. I visit the machine once a month and upgrade MacPorts and otherwise have a look. I've written about this machine on a previous thread. This machine sits in a remote location and does nothing but run shell scripts 24/7 that run a webcam and keep the machine connected to a captive portal Internet connection. I have a Late 2010 MBA (1.4 GHz Intel Core 2 Duo) with 2GB of RAM and 25GB of free storage.
