Mac OS 10.4 on HP ProBook 640 G1 Switching from Clover to OpenCore.

Hey guys, this is my first hackintosh. I'm on Mojave 10.14 and I'm planning to switch from Clover to OpenCore.

Hardware

HP ProBook 640 G1

CPU: i5-4300M

GPU: Intel HD Graphics 4600

RAM: 2x4Gb DDR3 1600 Mhz SK Hynix

WIFI + Bluetooth: Internal Intel Wireless-AC 7260 (Only Bluetooth part is working thanks to zxystd's IntelBuetoothFirmware) and WIFI only USB dongle TP-LINK TL-WN725N

Currently everything is running just fine apart from:

1. internal WIFI not working at all
2. sometimes instead of sleeping the computer just reboots
3. sometimes all USB ports turn off randomly after start up or reboot and to get them back I need to shutdown and restart again.

Any help would be highly appreciated.

Thanks.
