Apple reportedly will confirm the Mac’s transition to ARM chips during its Worldwide Developers Conference keynote on June 22.
The company has been using Intel processors inside the Mac since it ditched PowerPC chips in 2006. But speculation regarding a move to custom CPUs has been growing as Apple’s own chips have become incredibly powerful.
We may not see an ARM-powered Mac this year, however. Sources say Apple plans to announce the initiative, code-named Kalamata, at WWDC 2020. That would give developers time to adjust before the first ARM Macs arrive in 2021.
