Fixing Wi-Fi Drops After Sleep on MacBook Pro 2015 (Sonoma)
If you have upgraded your Mid 2015 MacBook Pro to macOS Sonoma using OCLP and are experiencing Wi-Fi disconnections after waking from sleep, the issue is very likely related to your modified SMBIOS.
Why is this happening?
Changing your SMBIOS to MacBookPro15,2 (to spoof a 2018 model for Universal Control) forces macOS to apply power management and networking profiles designed for completely different hardware. This often breaks sleep/wake functionality for the native 2015 Wi-Fi card.
Step-by-Step Fix
- Revert the SMBIOS (Recommended): The most reliable fix is to revert to your native SMBIOS. Open OpenCore Legacy Patcher, go to Settings > SMBIOS Settings, and change the Spoof Level back to Minimal or Default. Rebuild OpenCore and restart.
- Universal Control Alternative: If you desperately need Universal Control on your native hardware, look into third-party solutions or specific FeatureUnlock kexts rather than globally spoofing a newer Mac model.
- Reset Network Settings: If you have reverted the SMBIOS and the issue persists, go to System Settings > Network > Wi-Fi. Click 'Details' next to your network and select 'Forget This Network'. Reconnect to the network fresh.
Original Question: "MacbookPro mid2015 15‘Regarding the issue of Wi-Fi not working properly after upgrading to the Sonoma system."
First of all, thank you to everyone who takes the time to read this post.
I own a MacBook Pro (15-inch, Mid 2015) and recently upgraded it to macOS Sonoma using OpenCore Legacy Patcher (OCLP). In addition, I changed the SMBIOS to MacBookPro15,2 in order to enable Universal Control.
Since completing the upgrade, I have encountered an issue with Wi-Fi reliability. Whenever I close the lid and allow the MacBook to remain asleep for a period of time, the Wi-Fi connection is lost upon waking. This has become quite frustrating in daily use.
I would like to know whether this is a known or expected side effect of running Sonoma on this model with a modified SMBIOS, and if there are any proven solutions or workarounds available.
Any advice or insights would be greatly appreciated. Thank you!
在此先謝過點進貼文的各位
情況是這樣的，我是一台MacBook Pro（15-inch，Mid2015）機主，我目前幹的事：使用OCLP將macOS升級至Sonoma，並修改了SMBIOS至MacBookPro15,2為了能夠使用通用控制功能。在我更新完了之後出現了Wi-Fi無法持續連接的問題，一旦合上MacBook的蓋子稍久就會斷聯，讓我很苦惱，這是必然會出現的問題嗎？是否有解決的辦法？謝謝各位！
