Hello everyone,,




Decided to just toss my Catalina EFI onto a OC 0.6.3 + Big Sur USB and it booted right up!(OC GUI and Chime!) Will admit though, I installed on a different SSD incase things hadn't worked https://mobdro.bio/ https://kodi.bio/.

CPU: Intel i5-4210U

GPU: Intel HD Graphics 4400

RAM: 8GB 1600Mhz DDR3

Audio Codec: ALC280

Make and Model: HP EliteBook Folio 9480m

Ethernet Card: Intel I218LM PCI Express Gigabit Ethernet

Wifi/BT card: AC7260

TouchPad: Synaptics PS/2 Touchpad/TouchStyk

Guide used: OpenCore Vanilla Guide(Laptop[Haswell])


- iServices

-restart and shutdown correctly


- Everything else I forgot
