BRUSSELS, July 7 (Reuters) - Apple ( AAPL ) took a

challenge against EU regulators to Europe's second highest court

on Monday after they fined it 500 million euros ($587 million)

earlier this year for breaching landmark rules aimed at curbing

the power of Big Tech.

The European Commission in a decision in April said the

iPhone maker's technical and commercial restrictions that

prevent app developers from steering users to cheaper deals

outside the App Store breached the Digital Markets Act.
