What do you mean?
I have been running Logic on two computers at the same time on several occasions without any issues.
EDIT: Did some research.
This article: https://support.apple.com/en-us/HT202752, refers the section "On how many computers can I install Logic Pro X?" to this article: https://www.apple.com/legal/internet-services/itunes/us/terms.html#APPS
"App Store Content:
- The term “App” includes apps, iMessage and Apple Watch apps, in-app purchases, extensions (such as keyboards), stickers, and subscriptions made available in an app.
- You can use Apps on any device that you own or control.
- Individuals acting on behalf of a commercial enterprise, governmental organization or educational institution (an “Enterprise”) may download and sync Apps for use by either (i) a single individual on one or more devices owned or controlled by an Enterprise; or (ii) multiple individuals on a single shared device owned or controlled by an Enterprise. For the sake of clarity, each device used serially or collectively by multiple users requires a separate license."
Unless you count as an enterprise you can use the app on every computer that you "own or control".
