Apple's new Studio Display XDR monitor has limited functionality on older Silicon Macs

"Mac models with M1, M1 Pro, M1 Max, M1 Ultra, M2, and M3 support Studio Display XDR at up to 60Hz. All other Studio Display XDR features are supported. So even if you have a hotrod M1 Ultra-based Mac, the Studio Display XDR's refresh rate is capped at 60Hz - despite the fact that the chip can drive third-party monitors at 120Hz."

"Intel Mac support isn't mentioned at all in the compatibility list for either display, though they may function in some limited manner when connected. Intel Macs just received their last new OS update with macOS Tahoe (and only three more years of security updates), but it's still surprising that they're not compatible with Apple's latest monitors."

"Only the iPad Pro M5 supports the Studio Display XDR at 120Hz, with all other compatible models (in the iPad Pro and iPad Air family) limited to 60Hz."

Apple's Studio Display XDR monitor has significant compatibility limitations across Mac models. All Apple Silicon Macs support the display, but M1, M1 Pro, M1 Max, M1 Ultra, M2, and M3 models are restricted to 60Hz refresh rates instead of the full 120Hz capability, despite these chips supporting 120Hz on third-party monitors. iPad Pro M5 is the only iPad model supporting 120Hz, while other iPad Pro and iPad Air models are limited to 60Hz. Intel Macs receive no official compatibility mention for either the Studio Display XDR or the standard Studio Display, though they may function in limited capacity. This lack of support is notable given Intel Macs still receive security updates through macOS Tahoe.
