Epomaker EK21 vs LUMA100: your questions

Yes. The manufacturer lists Mac compatibility, and the LUMA100 includes six additional Mac keycaps in the box to replace the Windows modifier keys for easier recognition.
The LUMA100 has a larger 3000mAh battery compared to the EK21's 1000mAh battery. While actual runtime depends on usage and lighting, the LUMA100's larger capacity typically supports longer wireless operation between charges.
