MacBook Pro 15 2015抹除磁盘后macOS High Sierra互联网恢复卡顿求助

Hey there, let’s work through this frustrating stuck recovery issue on your 2015 MacBook Pro. I’ve helped several users resolve similar problems, so here’s a structured set of steps to try—starting with the quickest fixes first:

Quick Resets to Clear Stuck Caches #

• Force restart internet recovery: Hold the power button until your Mac shuts down completely. Then immediately press and hold Command + Option + R until you see the globe icon. This refreshes the recovery session, often clearing cached connection issues that might be blocking progress.
• Reset NVRAM/PRAM: Shut down your Mac, then press and hold Command + Option + P + R as you turn it on. Keep holding until you hear the startup chime a second time, then release. This resets low-level system settings that can interfere with recovery processes.

Network Stability Checks (Even with "Good" Wi-Fi) #

Wi-Fi signal strength doesn’t always equal reliable connectivity for large recovery downloads. Try these:

• Switch to a wired connection: If you have a Thunderbolt-to-Ethernet adapter, plug into your router. Wired connections eliminate Wi-Fi interference and packet loss that can stall recovery downloads.
• Manually set reliable DNS servers: In recovery mode, open Utilities > Terminal and run one of these commands to switch to public DNS:

  # Google DNS
  networksetup -setdnsservers Wi-Fi 8.8.8.8 8.8.4.4
  # Cloudflare DNS
  networksetup -setdnsservers Wi-Fi 1.1.1.1 1.0.0.1
  

  Quit Terminal and restart the recovery process afterward.
• Test with a mobile hotspot: If possible, switch to your phone’s cellular hotspot (note: this uses significant data). Sometimes regional routing issues with Apple’s recovery servers are bypassed with a different network.

Alternative Recovery Methods #

If internet recovery still stalls, these options are more reliable:

• Try local recovery (if available): Shut down your Mac, then press and hold Command + R (not the Option-included combo) to boot from the local recovery partition. Even if you erased the main disk, the recovery partition might still exist (it’s separate from your main volume) and can install High Sierra faster without relying on internet downloads.
• Create an external install drive: Use another Mac to make a bootable High Sierra USB drive:
  1. Download the macOS High Sierra installer from the App Store (you may need to search for it, or use Terminal to fetch it directly):

     softwareupdate --fetch-full-installer --full-installer-version 10.13.6
     

  2. Plug in a USB drive (8GB+), format it as Mac OS Extended (Journaled) in Disk Utility, named MyVolume.
  3. Run this Terminal command to create the bootable drive:

     sudo /Applications/Install\ macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install\ macOS\ High\ Sierra.app --nointeraction
     

  4. Plug the USB drive into your stuck MacBook Pro, hold Option while turning it on, select the USB drive, then erase your disk and install High Sierra from there.

Disk Health Check #

Even after erasing, underlying disk issues can stall installation:
In recovery mode, open Disk Utility, select your internal drive (the top-level entry, not just the volume), and click First Aid. Let it run a full check—if it finds and repairs errors, try the recovery process again.
