recognizing a hotspot on an iPhone

Your MacBook Pro and MacBook Air both run macOS 27.0.1, but only one recognizes the Personal Hotspot on your iPhone 12 mini running iOS 26. 

This establishes that the two Macs behave differently, but does not identify the cause. 

The most useful first step is to determine whether the affected Mac cannot find the hotspot or can find it but cannot connect.

On your iPhone, open Settings >> Personal Hotspot, enable Allow Others to Join, and confirm that Cellular Data is on. 

Keep the iPhone within 10 metres (30 feet) of the affected Mac. 

On the Mac, make sure Wi-Fi and Bluetooth are enabled, then open the Wi-Fi menu and check Other Networks. 

The hotspot’s network name is the same as the iPhone’s device name. Keep the iPhone’s Personal Hotspot screen open while testing.

If the iPhone’s name is missing, check whether the Mac can see other nearby Wi-Fi networks. 

If it cannot, investigate the Mac’s Wi-Fi connection. If it can, turn Wi-Fi off and back on, then restart both devices if necessary. 

Because the iPhone 12 mini supports Maximize Compatibility, you can also try enabling it under Personal Hotspot settings. This switches the hotspot to 2.4 GHz Wi-Fi and WPA2 security, which may help with compatibility.

If the iPhone appears but the Mac cannot connect, select it and enter the hotspot password if prompted. 

For Instant Hotspot without entering a password, Apple requires Wi-Fi and Bluetooth to be enabled on both devices, that they be within range, and that they meet the minimum system requirements. 

The devices should be signed in to the same Apple Account, or use the supported Family Sharing arrangement. 

A Mac can also connect through ordinary Wi-Fi using the hotspot password, so using different Apple Accounts does not by itself prevent a connection.

If Wi-Fi connection still fails, try connecting the iPhone to the Mac with a USB cable. If the problem persists, compare the two Macs’ Wi-Fi settings and check for available software updates. 

Since both Macs report the same macOS version, a version difference is not the explanation, although other configuration or hardware differences remain possible.

Apple’s guidance: Share your iPhone’s internet connection, Use Instant Hotspot, and If Personal Hotspot is not working.

The key question is, Does the iPhone’s name fail to appear in the affected Mac’s Wi-Fi menu, or does it appear but fail to connect?

That distinction will determine the most relevant next step.

One Mac sees the hotspot while the other does not usually because of Apple Account (iCloud) sign-in differences, Bluetooth/Wi-Fi handoff settings, or a stored network glitch. 

Why One Mac Recognizes the Hotspot and the Other Doesn't

• Different Apple Accounts: Apple's Instant Hotspot feature allows a Mac to automatically discover and turn on an iPhone's hotspot only if both devices are signed into the exact same Apple Account. If one Mac is logged into a different Apple Account or a Family Sharing account with different permissions, it won't show up automatically.

• Bluetooth or Wi-Fi Disabled in the Background: Instant Hotspot relies on Bluetooth Low Energy (BTLE) and Wi-Fi handoff to communicate between the Mac and iPhone. If Bluetooth is turned off on one Mac, or if Handoff is disabled in System Settings > General > AirDrop & Handoff, that laptop cannot ping or detect the iPhone.

• Corrupted or Cached Network Profile: If the non-working Mac previously tried to connect and failed, it may have a broken profile saved in its known network list.

• "Allow Others to Join" Requirement: If the laptops are not on the same primary Apple Account, the iPhone requires Allow Others to Join to be manually toggled on in iOS, and you must stay on that screen for non-paired devices to scan it.

How to Make a macOS Laptop Recognize and Connect to an iPhone Hotspot



Method 1: Use Instant Hotspot (Same Apple Account)

1. Sign in to the same Apple Account on both your iPhone and the problematic Mac.
2. Turn on Wi-Fi and Bluetooth on both devices.
3. On your Mac, click the Wi-Fi icon in the menu bar or Control Center.
4. Look under the Personal Hotspot section and select your iPhone’s name. The Mac will turn on the iPhone's hotspot remotely.

Method 2: Manual Connection (Different Accounts or Standard Wi-Fi)

1. On your iPhone, go to Settings > Personal Hotspot.
2. Turn on Allow Others to Join and note down the Wi-Fi Password.
3. Keep the Personal Hotspot settings screen open on your iPhone (some iPhones stop broadcasting if you leave the screen immediately).
4. On your Mac, click the Wi-Fi icon in the menu bar, select your iPhone from the available networks, and enter the password.

Method 3: Fix a Mac That Won't Detect the Hotspot

• Toggle Wi-Fi: Turn off Wi-Fi on the Mac for 10 seconds, then turn it back on. 
• Forget the Network: On your Mac, go to System Settings > Wi-Fi, scroll to Known Networks, click the Info (i) or details button next to the iPhone hotspot, and select Forget This Network. Restart both the Mac and iPhone, then reconnect.
• Rename the iPhone: Go to Settings > General > About > Name on your iPhone and slightly change the name (e.g., add a number or letter) to refresh its broadcast ID.

Personally, I have an iPhone 14 Pro and an M5 iPad Pro, and both of my MacBook Pros routinely connect to either of them via the Instant Hotspot when working away from Wi-Fi.

Just a quick question. If my iPhone is connected to wifi and my iPad is also connected to the same network. Both are connected to the same Apple ID, Could the iPad which is not a cellular device be using the iPhone to use the phone app as well as the iMessages app.

Bluetooth is on both devices and they are both connected to the same Apple Account.

After reading this, I can tell that this is not good practice. Advice please. 🙏

Yes, that can be happening by design and should not be a problem, though it can be disabled.

Separate Apple Accounts for each device? That is not generally a good idea. At all. The whole point of having devices on the same Apple Account is the interconnectivity offered. Features like continuity, handoff, message forwarding can be disabled if you don't use them. But two-factor authentication also relies on having >1 Apple device on the same Apple Account.

Im not going pester you anymore, you have been very helpful.

I see your logic. About 1 Account. 2FA massively.

I am just wanting to use the wifi IPAD without any apps that are not on my iPhone, and use it as a mini computer, if you get my drift. No phone or messages.

And more iCloud storage.

Then again the 2FA that is not enabled, maybe contributing to the location issue.

Thanks. Speak soon👌

Just noticed this is the United States forum. Any ideas. 👍
