Glad to hear, "it's time!"
Two caveats regarding Monterey:
- In many cases, the Intel I-225V 2.5GbE Ethernet port may not establish a connection. The other Ethernet port (1GbE) works properly. If both ports are needed, we recommend a USB-to-Ethernet adapter. These are available in both 1GbE and 2.5GbE varieties. In fact, Qnap makes a 5GbE version that's compatible with macOS.
- Samsung NVMe SSDs may caused long boot times (60-90 seconds) due to incompatible TRIM. If this happens, we recommend switching to a different brand such as WD 750 (PCIe 3.0) or WD 850 (PCIe 4.0).
Finally, if you are having difficulty with the update to OpenCore 0.7.5, feel free to describe the problem. For Catalina we recommend setting
SecureBootModel to
Disabled.
