About Marcus Sullivan

Marcus Sullivan is the editorial byline used for LogicPros. The site publishes independent guides to Logic Pro, with emphasis on current Apple documentation, reproducible workflows, and corrections when product requirements or pricing change.

What we can verify

LogicPros does not currently publish independently verifiable education, employer, client, or award records for this byline. Those claims have been removed. The author page describes the work performed for this publication rather than credentials we cannot substantiate externally.

How guides are checked

Version-sensitive claims are checked against Apple release notes, support documents, App Store listings, and vendor documentation. Where Apple's pages disagree — as they currently do around some Intel references — the guide states the current product requirement and explains the documentation conflict instead of presenting an edge case as official support.

Hands-on language is used only when the workflow can be reproduced. Exact performance numbers, session counts, or timelines are not presented as evidence unless the test setup and result are documented. Community reports are treated as directional evidence, not proof that every system will behave the same way.

Corrections and commercial policy

If a price, compatibility statement, or workflow step is wrong, email hello@logicpros.net. Corrections are made in the article and reflected in its updated date. Affiliate relationships, when present, do not determine rankings or recommendations.
