A: Hi, a single UPDF license allows login on one account that can be used on one Mac and one Windows device at the same time, but it does not currently support simultaneous use on two Macs or two Windows devices. If there is a need to use multiple devices, you may refer to our UPDF Enterprise Plan on our official website for more details.

If you have any other questions, you can also contact our support team at [email protected]. Thank you for your support and understanding.
