Many users are modding the card and re-routing USB to a USB 3.0 card or USB 2.0 Hub. I use the same idea and routed the USB from the Lenovo PCIe card to a USB 3.0 port. This works on both Big Sur and Monterey. I lose a PCIe slot, but I can live with that.\n\nBecause of race conditions during macOS boot with Mac Pros years 2008 to 2012, Open Core Legacy Patcher is recommended and OCLP can compliement BigMac2. Update: the race condition may no longer be an issue with current version of Big Sur and Monterey. There may be some issues updating to the proper firmware for a new OS version. Investigating.\n\n### First Time User Guide macOS 11.2.3 (from an unsupported Mac)\n* 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)\n* If Bigmac2 app does not run, try resigning it: `codesign --force --deep --sign - /Applications/bigmac2.app`\n* If you have Bluetooth 2 EDR Card, remove it. You can reinstall it later after you run the Disable Bluetooth patch\n* For 2008 Mac Pros: If you have not installed dosdude1's APFS ROM Patcher, do that first. (2009 - 2012 Mac Pros with upgraded firmware do not need this),\n* If you want native WiFi and BT4, do yourself a huge favor and get a 802.11ac/BT4LE Broadcom black iMac style combo card. This will also give you Airdrop and Handoff without any weird hacks.\n* Install BigMac 2 to an external hard drive or USB Flash thumb drive (should be relatively fast and min of 32 GB)\n* Next disable SIP. Boot BigMac 2 up from an external USB 2.0 on an unsupported Mac:\n  * `csrutil`\n  * `csrutil disable`\n  * `csrutil authenticated-root disable`\n\n * This should stop the Kill -9 errors users have been getting\n\n * BigMac2 should behave from the USB 2.0 disk and on Internal SSDs. If you ZAP your PRAM, repeat.\n\n * If you cannot disable SIP, do this from a Recovery Disk or Create install media disk.\n\n### Installation of macOS 11.2.3 from a Supported Intel Mac \n  * Boot into Recovery: Cmd-R at boot\n  * Open Terminal. These next steps are required to run BigMac2 and CloneToolX from a bigmac2 install disk from a Supported Mac:\n    * `csrutil`\n    * `csrutil disable`\n    * `csrutil authenticated-root disable`\n\n   * Download BigMac2 beta\n   * if Bigmac2 app does not run, try resigning it: `codesign --force --deep --sign - /Applications/bigmac2.app`\n   * Select install macOS Monterey beta 2\n   * Boot from bigmac2\n   * From the Springboard, launch bigmac2\n   * From bigmac2's pre install tab, Launch the installer. In five seconds, the macOS installer will be shown.\n   * Several reboots will happen\n   * When welcome screen shows, shutdown.\n   * Boot back into the bigmac2 intall disk\n   * For Mac Pro 3,1 run the Telemtery post install by itself\n   * Then for all systems, delete the APFS Snapshot by itself\n   * Shutdown\n   * Now see if the USB 2.0 install boots on your unsupported Mac (this will be slow)\n   * If success, you can now clone your system to BigMac. Besure to remove the live snapshot on the clone using bigmac delete snapshot.\n   * Install any other post install items from bigMac2 and also check Bless and update KCs.\n  \n### Future OC instructions when BM includes OC integration:\n  * placeholder\n  \n### Monterey Beta 2 is Experimental\n* This is what we know so far:\n  * Legacy WiFi cards will not work. Upgrade to 802.11ac/BT4LE Cards\n  * BlueTooth 4LE 20702B0 Cards are currently only working with beta 1.\n  * Having zero luck with USB Bluetooth cards on Monterery.\n  * We will be testing IntelWireless WiFi / BT combo cards soon with third party drivers.\n  * USB 2.0 devices will only work with a USB 3.0 Hub or Switch. This includes Apple USB 2.0 Devices. ;(\n  * If the progress bar boots slowly and not far, that usually means that it will boot up.\n  * With Race Condition, a full system seems to boot better when not in Verbose mode. This could just be voodoo.\n  * For AMD cards MouSSE is not needed. It's only needed on Mojave. I run an RX 580 8GB flashed and a Radeon Pro WX4100 non flashed. Neither need MouSSE. It will be removed from future versions of bigmac2.\n \n\n\u003cimg width=\"1920\" alt=\"Screen Shot 2021-07-03 at 3 41 35 PM\" src=\"https://user-images.githubusercontent.com/52664524/124365543-c48e8d80-dc16-11eb-961b-0e6f83a94b86.png\"\u003e\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2FSuperBox64%2Fbigmac","html_url":"https://awesome.ecosyste.ms/projects/github.com%2FSuperBox64%2Fbigmac","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2FSuperBox64%2Fbigmac/lists"}
