I'm facing a persistent instability issue with my Dell Vostro 5471 and would greatly appreciate your expertise. I've Success fully installed macOS Monterey, but the main problem is booting itself. It takes about 10 to 15 reboot attempts for OpenCore to Success fully boot from the USB drive. Once it boots, the system runs perfectly stable.
This issue occurs both when booting from the USB and from the internal SSD (after copying the EFI). This leads me to believe the problem lies within my EFI configuration, not the installation itself.
Here are my specs and details:
- Model: Dell Vostro 5471
- CPU: Intel Core i5-8250U (Kaby Lake R)
- GPU: Intel UHD 620 (dGPU Radeon 530 is disabled via -wegnoegpu)
- RAM: 8GB DDR4
- Storage: SATA SSD
- Audio Codec: Realtek ALC256 (using ALC3246 layout)
- Wi-Fi/BT: Intel AC 3165
- OpenCore Version: 0.8.8
- SMBIOS: MacBookPro15,2
The Problem:
When I select the OpenCore USB from the boot menu, most of the time it results in a black screen, and the system reboots or hangs. After trying this repeatedly (power cycling the machine), it eventually boots Success fully into the OpenCore picker and then into macOS. There are no Kernel Panic s or verbose text on failed attempts; it just fails silently before the verbose log even starts.
My goal is to install macOS Sonoma, but I decided to start with Monterey
