Got a mail from Metric Halo today... Updates for mac, and............................................. they now support two activations on both mac and windows
"All new licenses have two activations available. All existing licenses have also been updated to support two activations. This change applies for both macOS and Windows.
If your existing license has already been activated to a machine or an iLok, you may not have an available activation in your iLok account. This issue can be resolved by deactivating the existing activation back to your account; once you have done this, the number of activations available should update to two - then you can re-activate the license onto your machine or iLok and you will have another activation available in your account.
