UESPWiki:News/ESO Will Not Support ARM-based Macs
Elder Scrolls Online Will Not Support New ARM-based Macs — November 17, 2020
The Elder Scrolls Online team has announced that they will not be supporting the new ARM-based Macs in the future. Last summer Apple announced that their new Macs would stop using Intel CPUs, a change that would require all software running on Macs to either be rewritten, or run through an emulator. Matt Firor, the Studio Director for ZeniMax Online Studios has stated that they will not be porting ESO due to the difficulties inherent with that undertaking. At the same time, he has also stated that Intel-based Macs will remain supported for as long as there are enough users to justify it.
While ESO could be run on the new Macs through emulation, this experience is not going to be officially supported by ZeniMax. The official announcement can be seen here.
