Symptoms
- Startup shows a spinning globe icon instead of the usual Apple logo
- The Mac appears to be searching for a network startup server
- Problem started after resetting NVRAM/PRAM or changing startup disk settings
- Normal internal startup drive isn't being selected automatically
Likely causes
- CommonStartup disk setting pointing to a network boot option instead of the internal driveThis can happen after certain resets or IT-managed configurations.
- CommonNVRAM/PRAM reset clearing the usual startup disk selectionThis can sometimes default to a network boot search afterward.
- PossibleThe Mac was previously used with network startup (common in some managed/enterprise setups)This setting can persist if not manually changed back.
- PossibleA corrupted startup disk causing macOS to fall back to searching elsewhereThis is a more serious underlying cause worth ruling out.
- Less commonA held-down key (like N) during startup accidentally triggering network bootThis is an actual macOS startup key combination that can be triggered by accident.
What to do
- Force a restart by holding the power button for about 10 seconds.
- As it restarts, hold the Option key to bring up the Startup Manager and manually select your normal internal startup disk.
- Once booted normally, go to System Settings > General > Startup Disk and confirm the correct internal drive is selected as the default.
- If Startup Manager doesn't show your internal drive at all, that points to a more serious disk issue requiring Recovery Mode.
- Boot into macOS Recovery and run Disk Utility's First Aid on the internal drive to check for errors.
- Reset NVRAM/PRAM again cleanly (Option+Command+P+R) if the network boot behavior persists after selecting the correct disk.
- Avoid holding unrelated keys during startup once things are working normally.
- If the internal drive never appears as an option in Startup Manager, the drive itself may need professional evaluation.
Tools and parts
- None required
When to call a pro
If the internal startup drive doesn't appear at all in Startup Manager, an Apple-authorized shop can check for a failed drive.
