I am running 10.8.5 on my Mac tower. When I try to activate, your web activation asks for a machine ID and won’t accept anything I try to put in that space. I’ve tried my tower’s serial number and it’s MACaddress.
I have Mac OS 10.10.5 running on this Mac as well...I put my machine I.D. and serial number in to get an activation code, but it just says wrong computer ID
Assuming the MAC version activation process is the same as for other Magix programs activation should be done online.
The only time a computer id is needed is if you are trying to register the software prior to installation or offline. The id required is generated when using the Activate off line/by email option - did you use this option?
