Update: the race condition may no longer be an issue with current version of Big Sur and Monterey. I lose a PCIe slot, but I can live with that.īecause of race conditions during macOS boot with Mac Pros years 2008 to 2012, Open Core Legacy Patcher is recommended and OCLP can compliement BigMac2. I use the same idea and routed the USB from the Lenovo PCIe card to a USB 3.0 port. Many users are modding the card and re-routing USB to a USB 3.0 card or USB 2.0 Hub. The culprit for my BCM 20702B0 card not working after Monterey Beta 1 is USB. This weekend I started experimenting with a Lenovo WiFi 802.11ac/Bluetooth 4.2LE PCIe card using a combination of Open Source drivers that mess well with Apple's and was able to get Handoff working with Monterey Beta 2 and currently have WiFi and BT working on Big Sir 11.2.3 and Monterey Beta 2 and 3. Bluetooth, WiFi, Handoff possible on Monterey (Mac Pro 3,1 4,1 5,1): Added Support for macOS Big Sur 11.6.8, macOS Monterey 12.5 as of 8.13.22 For Mac enthusiasts who want to run macOS Big Sur or macOS Monterey on Unsupported Mac hardware.
