My MacBook Pro (2017 ver. / no ethernet port) is connected to a WiFi connection and I am trying to use Internet Sharing so that I can connect my Philips Hue Bridge to the internet. I quickly bought a USB-C to Ethernet adapter from Amazon thinking that would work but I am guessing this can only be used to get an internet connection to my MacBook from a router/modem, instead of sharing the connection from the MacBook to another device? Any insights/help would be greatly appreciated.

I have a MacBook Pro Retina 2012 running Mojave. I was using USB ethernet on my Mac and sharing that as a WiFi to my android phone. All was stable. Last week I had a partition error while I was resizing the disk and OS had crashed. I had to reinstall Mojave. Now I’m trying to use the same setup. MacBook is getting internet from USB ethernet fine. I then shared the ethernet into my WiFi like last time for my Android. The Android connects to the WiFi but this time keeps saying no Internet. Mac can connect to WiFi, but cannot share internet through it. (I would guess the NAT server is not working or something like it) I don't know how to diagnose the problem and fix it. Please suggest.

I connect to a Cisco VPN Server and want to share that connection via wifi. Using the macOS Internet Sharing feature, I can only select one interface to share - either my LAN adapter, or the VPN connection. Clients on the wifi can then only connect to either the iNet, or the VPN. The VPN Server is only creating a split-tunnel connection - and switching to full tunnel is unfortunately not an option. Setting my nat rules directly in /etc/pf.conf/ works fine and solves my problem to a degree. I want to script and dynamically add them using a nat-anchor. Setting the anchor with load for an external config works, however when I define my anchor in pf.conf and try to populate my rules using pfctl like so:

echo "                                                                                                                                      
nat on en8 from bridge100:network to any -> (en8)
nat on utun1 from bridge100:network to any -> (utun1)" | pfctl -a my.anchor -f -

or as a one-liner:

echo -e "nat on en8 from bridge100:network to any -> (en8)\nnat on utun1 from bridge100:network to any -> (utun1)\n" | pfctl -a my.anchor  -f -

(w/ or w/o the trailing \n) I can confirm that the rules are set on my anchor using pfctl -sn -a my.anchor but the actual routing remains unchanged. What am I doing wrong here?

I'm trying to host my Mac's internet connection to my other devices. But I can't set the password, nor I can't change my Wi-Fi host name from Wi-Fi Settings panel. I'm trying to change and click "done" but it never sets a password and shows the device a Wi-Fi without a password. I'm on MacOS Sonoma 14.0.

My iPhone is connected to Wifi A*. I want to "forward" this connection to another Wifi. I'm aware that one would need 2 Wifi chips to connect to Wifi A and open a hotspot for Wifi B. However, I found that a MacBook can share the iPhone's Mobile Data connection to a new Wifi (Wifi B) through USB in "Internet Sharing" in the settings. This works because then the MacBook can use the single Wifi chip it has for the hotspot and get its internet connection through USB instead. Unfortunately I can't use the iPhone's mobile data for this. Is there a way to make it work like that: **Wifi A** **iPhone** **MacBook** **Wifi B** *Wifi A has a captive portal the Hotel's TV can't pass which is the reason I want to create Wifi B.

I want a Mac to act as a Wi-Fi access point, but route the traffic not directly to the upstream internet connection, but into an UTM virtual machine. Method I currently use works, but requires circuitous setup with multiple moving parts: * For "internet sharing", special new interface was created using "System settings" -> "Network" -> "Manage Virtual Interfaces..." -> Add bridge. * A pair of virtual interfaces was created (ifconfig feth0 create; ifconfig feth1 create; ifconfig feth0 peer feth1; ifconfig feth0 up; ifconfig feth1 up). * First of the virtual interfaces was added to the manually created bridge (ifconfig bridge1 addm feth0). * In UTM virtual machine settings, additional bridged network interface was added. But UI only shows en0 and en6 as possible variants (not feth1 I need), so I needed to remove it and re-add using raw QEMU arguments: -netdev vmnet-bridged,id=net1,ifname=feth1 -device virtio-net-pci.... This results in another bridge being created when the VM starts. The scheme works as intended, but I feel that it can be optimised/simplified somewhat. Specifically: * How do I avoid needing to create two bridges instead of just one (or maybe zero)? Maybe there are other useful QEMU modes that allows one to attach existing bridge? * How do I avoid a double NAT and double DHCP servers (one inside the VM, one made by Mac's Internet sharing)? * Can I somehow turn on Internet Sharing with partial components (I want Mac to manage the Wi-Fi part, but not the DHCP / routing / address translation)? What are ways to activate the access point mode besides the official "System Settings" -> "Internet sharing"?

I've been having this problem for months, and I finally need help. I found other topics on connection problems, but not quite the one I have. When I'm at home I use a Wifi hotspot from my Android phone which has unlimited data, and my Macbook tends to disconnect quite often from this network, sometimes more often than others. However my phone still has internet and other devices, like my playstation, can connect without problems. Even more surprising, if do something that "continuously" uses internet, like Zoom calls, the Macbook almost never loses the connection. Furthermore, when my Macbook disconnects, turning on the Playstation, also connected to the hotspot Wifi, seems to resolve the connection issue! The Macbook has no problems to connect to any other Wifi network, like at work or at friend's places. Do you have any clues on how to stabilise the connection of my Macbook when using the hotspot from my phone?

Has anyone figured out reverse tethering (AP mode) Internet on macOS Sequoia 15.4.1 M1 Arm when macOS is Internet sharing over ethernet (via usb 10/100/1000) to broadcast a new WiFi AP? - I confirmed I have Internet with the ethernet in the USB hub in macOS. - I verified that this is en8 interface with the USB 10/100/1000 name - I enabled Internet sharing over the same interface over WiFi to turn macOS into an AP - I configured the WiFi SSID to broadcast under a custom name with a custom WPA2/3 password - My WiFi Internet icon on the top right says I'm sharing over channel 11 The issue is: - My phone can see a new broadcasted SSID but its the hostname of my laptop instead of my custom SSID name - When I connect my phone to macOS AP WiFi, there is no Internet - Network settings in macOS show that the WiFi is 'Not Connected' - No error messages are shown - I checked logs in /var/logs and no luck This seems like a configuration issue. How can I debug this? I looked at related questions and couldn't find a way forward.

How can I share my Mac's wi-fi connection with my iPhone? I am currently travelling (roaming out of country) and I am needing to work on the development of my iOS app, though an internet connection appears to be needed for the phone, otherwise it won't approve the signature of the "in development" app, even though I had previously deployed it to the phone. I am now in a location where my computer managed to connect to wi-fi, but not my iPhone (sign-in process is spotty), so I am trying to see what possibilities there are to be able to deploy my app. BTW certain functionality can be tested in the simulator, but there is other functionality that needs a real device. What I have tried: - Connecting phone via USB and in "Sharing -> Internet Sharing" specify "iPhone USB", then enabling it - Connecting phone via Bluetooth and then in "Sharing -> Internet Sharing" specify "Bluetooth PAN", then enabling it Is there another solution or a step I might have overlooked? I am using iOS 9.3.1 and MacOS X 10.11.4.

I see someone had/has the same issue I'm seeing [here](https://developer.apple.com/forums/thread/656877) , but I can't find an answer to it. **What I'm trying to do**: create a packet filter that is applied to any device that's sharing internet. My use case has devices plugged into a Mac Mini via USB that shares the ethernet connection. **What I've done so far**: - Created a

/etc/pf.anchors/tethering

file with my desired rulesets - Modified the

/etc/pf.config

file so it looks like this:

#
# com.apple anchor point
#
scrub-anchor "com.apple/*"
nat-anchor "com.apple/*"
rdr-anchor "com.apple/*"
dummynet-anchor "com.apple/*"
anchor "com.apple/*"
load anchor "com.apple" from "/etc/pf.anchors/com.apple"

# Custom anchor loadings
anchor "tethering"
load anchor "tethering" from "/etc/pf.anchors/tethering"

- Run command

pfctl -E -f /etc/pf.conf

to load modified config - Run command

pfctl -sr

and get the following

scrub-anchor "com.apple/*" all fragment reassemble
anchor "com.apple/*" all
anchor "tethering" all

- Finally, I test a device that's already connected and everything behaves as expected. **What goes wrong**: Every time I connect a new device, my anchor appears to have no effect. I run the command

pfctl -sr

and get a different result (below). OSX automatically appends an anchor *com.apple.internet-sharing* that overrides my desired *tethering*.

scrub-anchor "com.apple/*" all fragment reassemble
scrub-anchor "com.apple.internet-sharing" all fragment reassemble
anchor "com.apple/*" all
anchor "tethering" all
anchor "com.apple.internet-sharing" all

**Finally - the question:** How do can I find - and therefore modify - the

.apple.internet-sharing

anchor? Or, how can I prevent this anchor from being automatically added? Thanks in advance for any and all assistance.

**Epilogue:** I have a cellular 5g connection with unlimited data(no cap) provided I use it only on my smartphone, if I use wifi hotspot to connect with my mac then the phone switches to 4g and a daily data cap of 2 GB is applied. Now I tried USB tethering from my android(Redmi note 9 pro) to my mac (MBA M3, 16/512, Sequoia 15.3) but could not get it working. However when I tried to do the usb tethering with my VM running it gave me an option to connect my phone to windows and hence I was able to use USB Tethering to my Windows VM inside my host mac machine to use this blazingly fast 5g without data cap. **Issue:** Now I want to use this fast internet from my windows 11 VM in VMWare fusion to my host machine mac. I am unable to find any relevant method to connect the two in a way I can share their internet. Please help me find a way to share internet between the two things.

Apple Cache Manager Utility question. We have just bought a second newer Mac mini to act as my school's Primary Apple Caching Server for our ever growing fleet of student iPads (over 500 and counting). I wanted to transfer/import/absorb the Cache from our old (Secondary) server into our new server on the same network... Wondering if anyone has ever successfully imported a Caching Server's cache from another using the commands provided by Apple in macOS Help? I have used variations of this command but have had no success, even when the Volume is mounted remotely using AFP, using the command mount_afp (ref: )

sudo AssetCacheManagerUtil absorbCacheFrom /Volumes/ServerHD-1/Library/Application\ Support/Apple/AssetCache/Data read-only

Would anyone know under what conditions the command from Apple can be used successfully? Thanks in advance...

On my iPhone 8 on iOS 16 I've disabled (or so I thought) internet sharing in settings. When I look for WiFi networks on my iPhone 6 however it presents my iPhone 8 there regardless, and if I try to connect it succeeds. Now, you might argue that I've only turned off internet sharing with a switch labeled "allow *others* to connect", which technically doesn't include my own logged-in iCloud devices. When I actually try to connect with my iCloud devices, though, that same switch *turns on by itself* which leads me to these conclusions: 1. The switch is meant to apply to iCloud devices, otherwise it would've stayed off, and... 2. The switch simply isn't respected with regard to iCloud devices **How do I prevent my other iCloud devices from being able to activate internet sharing on my iPhone?** The purpose of this exercise is to attempt to decrease distraction by eliminating even the possibility of an internet connection at certain times of the day, analogous to how the mere presence of a phone on the table in front of you has been shown to decrease your cognitive performance *even if you never pick it up *.

I'm trying to set up a hotspot, sharing the connection from an iPhone X running iOS 12.1 with a MacBook Pro running macOS Mojave. The hotspot is working fine and other devices can connect to it and use the internet, but although the MacBook connects to the hotspot OK, browsers don't work. The MacBook can ping the DNS server set by the phone's DHCP, and other servers, but lookup fails (dig, nslookup or the network utility tool), and all browsers report that there is no internet connection. I've tried going through the answers to this question but nothing seems to have made any difference. Both devices have been restarted multiple times, and I've reset the phone's network settings.

Lion doesn't seem to be giving out DHCP addresses when I turn on Internet Sharing. My firewall is off, I create a shared network with no security sharing ethernet->wifi. In Network Preferences the Wifi connection shows as yellow, with a self-assigned IP, and any device I try to connect (e.g., iPad) doesn't get an address. Help!

I have a device running embedded Linux and busybox that does not have WiFi, only Ethernet. When at home I successfully connect that device to the same router (through a switch) as my Mac and configure it using ifconfig eth0 192.168.1.63 && route add default gw 192.168.1.254. (busybox on the device does not include the udhcp client.) But when traveling I need to connect the device directly to my Mac with an Ethernet cable, through an Anker USB 3 to Ethernet adapter. I enabled Internet Sharing on my Mac. Inside System Information under Network the Ethernet adapter shows as "AX88179A". It shows "IPv4 Addresses: 169.254.2.40". Here are the results from ifconfig en8:

en8: flags=8963 mtu 1500
	options=404
	ether a0:ce:c8:74:6c:ef
	inet6 fe80::4bc:d253:1602:7ba9%en8 prefixlen 64 secured scopeid 0x1d
	inet 169.254.128.214 netmask 0xffff0000 broadcast 169.254.255.255
	nd6 options=201
	media: autoselect (100baseTX )
	status: active

My questions are: How to I assign an IP number to the device that the Mac will be able to find a route to? How do I determine the gateway IP number to use on the device? Will the Mac (properly configured) route packets to my embedded device? (eg. Can I successfully ping a host outside the subnet from the device?) How do I determine the IP number for the device that I can use on hosts outside this subnet? Perhaps, that's not possible, since only the Mac--which is acting as a router--is visible. So can I configure the Mac to forward packets for specified ports to my device? (This would allow connect GDB running on a computer that is not on the subnet to GDB Server running on the device with an specific port. I would specify the Mac's IP number in GDB.) **Update:** Seamus 's comment suggests I assign one IP number to my Mac and one to the device, both on the same subnet. I guess as long as both start with 169.254. they will be on the same subnet, since the subnet mask is 255.255.0.0. But what does the IP number 169.254.128.214 in the results of ifconfig en8 indicate? Is that already assigned to my Mac? Or do I need to choose a different one for my Mac? And what IP number do I use for the gateway that I specify on the embedded device?

(I am a non-tech person, so apologies for my seeming simplistic language.) My MacBook Air (M1) (Sonoma 14.5) is connected to my university LAN network. I wanted to share the internet by following these steps: *System Settings -> General -> Sharing -> Internet Sharing*. This takes me to *Share your connection from USB 1-/100/1000 LAN* *To device using*: (this I set to) WiFi After this, I get the following warning: > Your internet connection cannot be shared because it is protected by 802.1X. Choose a different network to share or disable Internet Sharing. How do I fix this problem? My friend is able to share the same intenet from his Windows system without any issue.

I got some problems. So Ive connected an MikroTik with openwrt with my laptop over lan. The MikroTik has the ip address 10.10.1.200. I assigned my Mac the ip address 10.10.1.201 on the lan interface. My Mac is connected to the internet via the wifi interface. So with this configuration I got no problems connecting both. I can access via ssh. After I switched "internet sharing" on I can't access any more. I looked at my interfaces and routing tables and the look a little bit weird. I have no route to the subnet 10.10.1.0 any more and my lan interface doesn't have his ip. These are the routing tables when internet sharing is switched on : Internet: Destination Gateway Flags Netif Expire default (ip address of the wifi interface) UGScg en0 default link#18 UCSIg bridge100 ! 127 127.0.0.1 UCS lo0 127.0.0.1 127.0.0.1 UH lo0 169.254 link#6 UCS en0 ! 192.168.2 link#18 UC bridge100 ! That's not all of the routes, the others are not important. Here is the interface which is normally my lan interface: en5: flags=8b63 mtu 1500 options=6464 ether a0:ce:c8:c7:68:ef nd6 options=201 media: autoselect (1000baseT ) status: active The routing table looks like this when internet sharing is off: Internet: Destination Gateway Flags Netif Expire default (wlan interface ip) UGScIg en0 10.10.1/24 link#11 UCS en5 ! 10.10.1.201/32 link#11 UCS en5 ! 127 127.0.0.1 UCS lo0 127.0.0.1 127.0.0.1 The lan interface looks like this: en5: flags=8863 mtu 1500 options=6464 ether a0:ce:c8:c7:68:ef inet6 (unimportant) inet6 inet 10.10.1.201 netmask 0xffffff00 broadcast 10.10.1.255 nd6 options=201 media: autoselect (1000baseT ) status: active

I have two sources of internet, I want to combine both the internet sources and get increased speed. I have noticed by testing, I can either use Ethernet internet or the Wifi Internet at one time, but by default both don't combine.

I've got a Nov 2023 MacBook Pro running Sonoma 14.2.1. While initially testing Internet Sharing, I configured sharing from Ethernet to devices using Wi-Fi. In the dialog box to set up the Wi-Fi hotspot details (name, channel, security, and password) there were, I believe, around 8 channel choices to choose from. The first 4 I think were for the 2.4 GHz range, and the rest were for 5 GHz. After attempting some other setting options, like trying to share ethernet with iPad USB and failing to get that to work, I attempted go back to using Wi-Fi, however found that the channels "pull down" no longer had any choices to choose from. Unfortunately it seems to default to channel 11 now, which is far slower than where I had originally had it (Channel 48). I've tried rebooting, enabling / disabling Wi-Fi, etc., but I can't get that pull down to populate. I'm hoping someone here knows of a way to nuke where these settings are stored so that the GUI presents me with the channel list again, or barring that, finding the storage area where I can hand-edit that channel value. ![Internet sharing configuration dialog ][1]
