I have created a seed phrase for Electrum on "Tails" (Linux) and then imported those word phrases into Electrum for Windows before, but I have not done this for a Mac. I presume that the word phrases are not unique to any specific operating system, so you can import it into any Electrum wallet, no matter what OS you are using.

Ps : Do not use "Tails" without a Persistent volume, because you will lose it. It comes with a default Electrum wallet installed, but it is mostly outdated.
