fernando.c.neves Posted June 14, 2025 Share Posted June 14, 2025 (edited) I just finally done with macOS Tahoe 16, simple what I did is to create with OpCore Simplify (Mac Version). First I do create with windows my Report.json with the Hardware Sniffer, then create ACPI folder with the same App for Windows. After get the two (Report.json + ACPI - Folder) I used the OpCore Simplify for Mac. Here the final EFI folder. (With my USBPorts.kext) included. Now I can use USB with Keyboard/Mice. Creating macOS Sequoia 15.5 with Mist (USB bootable disk). And Upgrade After install. EFI - OC - B560M-H - 14-06-2025 - All Working.zip Edited June 14, 2025 by fernando.c.neves 3 Link to comment https://www.insanelymac.com/forum/topic/361162-pre-release-macos-tahoe/page/22/#findComment-2833549 Share on other sites More sharing options...

SavageAUS Posted June 14, 2025 Share Posted June 14, 2025 (edited) Well that was relatively straight forward for AMD. MacPro7,1 SMBIOS Just need to sort USB ports. No Wifi until OCLP is updated but have LAN so I can wait.

arsradu Posted June 14, 2025 Share Posted June 14, 2025 With the installation started from Sequoia I get back into reboots.

You must deactivate it by booting to recovery by following a previously posted procedure in this forum and you'll be good to go. Thanks for the info. Where would FileVault be enabled please, on the boot drive? I have Sequoia installed but do not have FileVault enabled on it.
