I have an iMac running Big Sur and need to upgrade. Running QB desktop 2021 standalone Mac R15.

I also have a MacBook air and just upgraded it to Sequoia 15.6.

Can I install the QB R15 dmg file on the MB Air and open it just for a test run or will it de-register on the iMac? Is the license for only one computer? If the test run is successful I will continue to only use it on the iMac after its upgrade.

Been a loyal QB customer for 30 years and don't need these problems in my old age.
