While initial reviews of Apple's M1-based Mac computers were very good, it seems more and more issues are popping up. First up, software compatibility seems more of an issue than first thought. An Apple enthusiasts even created a website called Is Apple silicon ready? to crowd-source data about how well software runs on the M1 SoC. The website reveals if software has an Apple silicon optimized version and whether users are encountering issues when using the Rosetta 2 emulation.
Now Apple Insider reports users are experiencing Bluetooth issues with M1-based devices. M1 users complain about sporadic disconnections and complete failures. It seems it's either a hardware issue with the M1-based computers or a bug in the macOS Big Sure operating system:
The issue appears to lie in Apple's hardware or macOS Big Sur, as users were able to successfully connect Logitech accessories using that company's Unifying Receiver Bluetooth dongle. One Redditor contacted Apple to replace his Mac mini, but the substitute suffered from the same problem.
Other than this, one big question that remains unanswered is whether the M1 will get proper support for Windows. Being able to dual-boot macOS and Windows via Apple's Boot Camp was a big selling point for the x86-based Macs but at the moment there's no sign it will get this easy for the M1-based devices. Unless Microsoft puts in effort to get the ARM-based version of Windows 10 on the new Mac, it seems virtualization will be the best bet. It's already possible to run Windows 10 on the M1 via the CrossOver 20 tool but this is not without issues.
