Installation of macOS 11.2.3 from a Supported Intel Mac If you cannot disable SIP, do this from a Recovery Disk or Create install media disk. This should stop the Kill -9 errors users have been gettingīigMac2 should behave from the USB 2.0 disk and on Internal SSDs. Boot BigMac 2 up from an external USB 2.0 on an unsupported Mac: Install BigMac 2 to an external hard drive or USB Flash thumb drive (should be relatively fast and min of 32 GB) This will also give you Airdrop and Handoff without any weird hacks. If you want native WiFi and BT4, do yourself a huge favor and get a 802.11ac/BT4LE Broadcom black iMac style combo card. If you have not installed dosdude1's APFS ROM Patcher, do that first. You can reinstall it later after you run the Disable Bluetooth patch If you have Bluetooth 2 EDR Card, remove it. If Bigmac2 app does not run, try resigning it: codesign -force -deep -sign - /Applications/bigmac2.app
If running Bigmac2 recovery / install disk from OWC 2.5" SSD, use a 4x PCIe slot (on Mac Pro 3,1 use the 3rd PCIe slot, not the 1st or 2nd 16x slots)
First Time User Guide macOS 11.2.3 (from an unsupported Mac) I lose a PCIe slot, but I can live with that. 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):

I will soon produce a guide on how to make the two products work seamlessly with each other. Added Support for Monterey 12.0.1 release as of īecuase of race conditions during macOS boot, Open Core Legacy Patcher is recommended and OCLP can compliement BigMac2.
