If you’re using Amulet Hotkey for KVM over IP, be warned that installing the latest version of macOS on your endpoints automatically re-enables temporal dithering.
This vastly increases the amount of information you’re forced to handle over IP and, as a result, will have a negative impact on the quality of your image.
Happily, Amulet Hotkey are already aware of the issue, and have released a kernel extension that allows you to disable temporal dithering at the driver level, regardless of which version of macOS you’re running. (If you’re running an earlier version of macOS or OS X, the fix should already be in place – contact us if you find this isn’t the case.)
The usual caveats apply: the fix will only work with Amulet hardware and software, not with that from third parties; the kext itself is not available publicly – in a delightfully cloak-and-dagger scenario, you need to get in touch with our team on the details below, and they’ll send you a temporary download link and instructions for how to install it.
