Hello everyone,
I have been trying to install macOS on this laptop for a while. No matter what I do the end result is the same. OpenCore boot menu comes up, choose option 1 to install macOS, then verbose text comes up for a couple of minutes followed by a blank screen with only the WiFi light blinking constantly. Checked the OC logs and the last recorded line is always the same: AmiShimTimerBoostExit changed current period to 100000 followed by a bunch of 1s and 0s which go on forever. The laptop sits in this status indefinitely.
I am not a complete noob and have followed the OC guide to a T multiple times to no avail. Searched high and low but no one seems to have an answer for this one.
Some facts:
- The USB installer was created on a real Mac
- This is a Legacy BIOS and the setup was created accordingly
- Have tried changing boot arguments specific to Intel graphics and other suggestions to no avail
- BIOS is the latest and 'Default' settings loaded
- Security chip disabled in BIOS
I have zipped up and uploaded the following files here if anyone is willing to help me out, please.
- config.plist
- OpenCore log
- Text file with USB EFI folder structure
Thank you for anyone who is willing to take the time to give this one a try. I'll be grateful for any feedback.
