Internet Sharing Refuses to Function

I have a mac OSX 10.4.11 and used to use the internet sharing in order to let my ipod connect, and before it worked fine. Then all of a sudden it didn't work anymore. I would turn it on, the grey arrow would appear in the airport symbol, then it would disappear, and I wouldn't be able to connect. I have tried everything, absolutely everything, and I haven't gotten the slightest change.
I also noticed in my fury that there was no internet sharing tab to click in the services panel. But I don't remember needing to click that when it worked before.
What is going on? Please help, I've been trying to make this work for almost a month!!

Thank you very much! I really need some help on this!
Alright, so the reason I mentioned that was because when I have been trying to find help on the internet, I am constantly confronted with this image. Most of the help tells me I need to make sure I have that internet sharing box checked.
http://mac.appstorm.net/wp-content/uploads/2009/04/sharingoptions-620x519.png
Now, my internet sharing folder looks much more like the one you provided. It has three tabs like yours, "Services, Firewall, and Internet". I was looking in the services tab, and didn't find an internet sharing in the list. However, a lot of sites also told me I needed to make sure Personal Web Sharing was checked, which I tried, and that didn't help me either. I really have tried everything I could think of.
Is there perhaps something else interfering with the internet sharing? Because it looks like it wants to work, the arrow appears, then blinks off immediately.
Thanks again for the help!

Can't create airport/wifi internet-sharing network with other laptop

I have an iBook running Tiger 10.4.11 connected to the net with ethernet. The internet connection comes through a radio antenna which acts like a router to which I don't have access.
I want to share my internet connection, and to be able to transfer files, between the iBook and another laptop. I've tried it with two - one running Fedora 11 (mine) and one running Windows XP, and have the same problems with both.
I turn wifi on on the ibook and linux laptop. I turn on internet sharing from built-in ethernet to airport in System Preferences. First I try it with no encryption. 'Other settings may interfere with internet sharing' shows up; it tells me to enable Personal Web Sharing, which I do. When I click start Little Snitch tells me natd wants to connect to 10.0.2.1 (presumably the router in the antenna), which I allow. I try to connect with the linux laptop and it tries then disconnects.
1) isn't personal web sharing for serving web pages? — why is it necessary here at all?
2) what am I doing wrong in making my network work?
If I enable encryption using WEP, the other password asks me for authenticication, I put in the password, and it then tells me the network has been disconnected.
3) is WEP the best encryption I can use from Tiger?
4) I think the problem's with Tiger (both laptops can connect to other wifi networks not set up by me). Is there a piece of free software I can use to share the connection instead of the built-in one?
I can't make a functional network in reverse either (i.e. setting it up on the other laptop and trying to connect wirelessly with the ibook).
What I am trying to do is precisely this (http://my.safaribooksonline.com/0596009135/runmacx2-CHP-11-SECT-13) — it just doesn't work.

When I click start Little Snitch tells me natd wants to connect to 10.0.2.1 (presumably the router in the antenna), which I allow. I try to connect with the linux laptop and it tries then disconnects.
Back on that part, at that Point the Mac is a NATD Router, don't try to connect to the other computers.
On the Mac, with Internet Sharing enabled, open NetInfo Manager in Applications>Utilities.
From there on out, it's a bit foggy, but iirc Config>DHCP>Subnets><the subnet>, then down where it says com.apple.nat... what does it report for IPs?
If it were say 10.43.29.1 then the others trying to join should have that as a Router/Gateway, and then 10.43.29.2, 10.43.29.3, etc. as IPs.
Apple says you can't set it Manually, but I've had it work a couple of times.

Computer - computer network and internet sharing

I apologise if this has been discussed elsewhere - please point me to any useful links.
I have a G4 iMac and iBook (running 10.4.6) both with airport extreme cards installed. I would like to use a computer to computer connection for file / printer sharign and most importantly to share the ethernet connection to the internet running through my iMac.
I would be extremely grateful if someone could point out how to do this and incorporate a practicable level of security (I don't want any of the hundreds of people in adjacent flats downloading lord knows what through my connection).
Having accomplished this, I then need to be able to create a similar connection when required so that when required I can share the internet connection from the iMac with our PC laptop running Windows XP service pack 2.
So, the simpler the better, instructions for creating a computer - computer network for internet and file sharing between two Macs and following that between the Mac with the internet connection and a Windows laptop.
Thank you very much in advance.
G4 iMac USB 2.0 / G4 iBook Mac OS X (10.4.6)

You don't need to setup up computer to computer connection if your using internet sharing. Once you start internet sharing then your 2 computers are connected togther.
I would be extremely grateful if someone could point out how to do this and incorporate a practicable level of security (I don't want any of the hundreds of people in adjacent flats downloading lord knows what through my connection).
The problem you have is that if you enable internet sharing on one of your macs to share its connection over airport then the only level of security you can enable is WEP encryption.
The problem with WEP encryption is that it offers no real security and can easily be cracked. WPA is the only security you should consider using and unfortunately OSX does not have WPA encryption functionality when using the built in internet sharing function.
Your best solution is to get a wireless router that has a SPI firewall an WPA encryption. Depending on what your current internet connection is and how it is provided would determine the best kind of router to get.

USB modem and Internet Sharing causes system to hang.

First my setup. I have a Mac mini (early 2009) running 10.7.2 connected to the Internet using a Sony Ericsson W910 as a USB modem. I am using Internet sharing via Ethernet to a 1st generation (n) AirPort Extreme to give Wi-Fi to other devices (iPhone, Xbox 360, PS3 etc).
Now the problem: When Internet Sharing is on regardless of what interfaces are used (Ethernet, Wi-Fi, Bluetooth PAN etc) eventually—that word is key—my system will hang. Internet will be unavailable to every device and my Mac itself (but they will still be connected to Wi-Fi) and any app that is running willbeachball. Any app I launch—or try to—will also beachball. I've tried leaving it to see if it will resolve itself —even overnight—but it always requires a hard reset.
The eventually part. I haven't figured out what causes this but I have an idea which I'll explain later. The times this happens is totally random. It has gone days with no problems and other times has happened minutes apart. Usually it's about every 12-24 hours.
It's definitely Internet Sharing which is causing this because when I turn it off I don't have any problems. I've tried every configuration. Only sharing via my mini's Wi-Fi or Ethernet, leaving the AirPort out etc. As soon as I turn on Internet Sharing I've started a countdown to a hang.
On inspecting the Console the last messages before a hang without fail are always:
12/12/2011 06:31:07.000 kernel: 80 80 AppleUSBCDCECMData: getOutputBuffer - Output buffer pool empty
12/12/2011 06:31:07.000 kernel: 80 66 AppleUSBCDCECMData: USBTransmitPacket - Output buffer unavailable
12/12/2011 06:58:58.312 com.apple.usbmuxd: _handle_timer Fish out of water!!!
Repeated hundreds of times. Quick Googling indicates that AppleUSBCDCECMData is a USB driver. Apparently I have version 4.1.15 which appears to be the latest.
I'm aware this is a rare configuration but I believe it affects every USB not just this particular phone.
Is anybody else experiencing this or knows a way to fix it?
Thanks.

Thanks Barry.
The hub is on its way to the manufacturer for after sales service...
But the issue with AirPort remains the same, even after resetting SMC.
Some clarification:
* It happens just after computer wakes up from sleep. Restarting solves the problem and the issue doesn't arise until computer goes standby again.
* The whole WiFi card becomes unresponsive. It is not only the Turn Off button, but the whole functionality is stopped. The card can not be activated/deactivated and it doesn't connect to any network. If it is used for internet sharing, clients are unable to connect.

USB hub and internet sharing stop working after sleep

Hi,
I have a relatively new Bluestork USB hub I purchased to connect multiple USB devices I have at the same time. It used to work correctly under Leopard, but now it stops working each time the computer wakes up from sleep. I have to restart the computer for it to start working again. Both link and power LEDs stay on, even when the hub is not recognized.
My second problem is related to internet sharing. It stops working after each sleep/wakeup cycle and the only way to make it work again is to restart the computer. It used to work correctly before Snow Leopard as well.
I have all the Mac updates installed.

Thanks Barry.

Internet sharing no longer works after 10.5.3 upgrade

I'm aware that a number of people seem to be having wireless networking problems after upgrading to 10.5.3. I apologise if this has been covered somewhere else, but after trawling the forum I haven't been able to find any posts which deal with my specific issue. So any suggestions would be gratefully received...
My 24" 2.8GHz Intel iMac (purchased in Feb 2008) is connected to the internet via ethernet cable through a Speedtouch router supplied by my ISP, o2.
This internet connection is shared wirelessly with the other computer in the house, a G4 MDD running 10.3.9. After switching on Internet Sharing within System Preferences on the iMac, the G4 picks up and connects to the network created by the iMac, which is called (My Name)'s iMac.
All very straightforward, and until a few days ago this set up worked perfectly.
Then I decided to upgrade the iMac from 10.5.1 to 10.5.3, using the Combo updater downloaded from the Apple website.
As far as the iMac is concerned, the upgrade went perfectly and I have no problems whatsoever. I can still access the internet without difficulty as before.
The problem is with the G4. It no longer picks up the network from the iMac. The network's name ((My Name)'s iMac) no longer appears in the drop-down list under the Airport icon in the G4's menu bar (although this list does still contain the names of various neighbours' networks, as it did before, so the Airport in the G4 does still seem to be functioning). Internet sharing on the iMac is still switched on, and the Airport icon in its menu bar indicates that it is "transmitting", but the G4 is just not "receiving" any more. As a result, we can't get online on the G4.
I would be very grateful if anyone could shed any light on this problem. If there is any further information I can supply which might help, please ask.

Hi SteveSCA-
Greetings and welcome to the Apple boards
Have you tried powering everything down and then back up again?
Have you repaired permissions on the iMac?

Internet Sharing + Lion = some lack of respect from Apple!

Snow Leopard worked great, although I had some issues sharing my built-in airport connection with PC's....
Now, all got better. Nothing works. Spent some hours on the web trying everything that worked for others.
I have a slick 3.2. GHz i3 Imac, with the built-in aiport utility (not very useful after all!)
My issue is that Macbook air, Ipad and Iphone can connect to the imac, but internet connectivity is NOT available. Don't even start me by trying to connect a PC again....
Alredy tried:
( i) changing the network name;
(ii) changing channels;
(iii) changing passwords, simpler passwords, no passwords;
(iv) putting manually the DHCP
(v) with several IP adresses.
(vi) DNS Servers as well. Only Google DNS worked....for googleing, nothing else. You try to hit a link and doesn't work either.
I was recommended to set up a router. I refuse. i didn't purchase this computer, with the built-in airport express so I have to set a router.
I searched for some official press release from Apple saying something. Not even that. Not even saying their are sorry for the inconvenient. The google experts at the store just told me to wait for an update....
If someone knows how to fix this, if there is something to be done, I'll appreciate.
Have a nice weekend!

I still don't know what you mean by this. AirPort Utility is an installable program. Why do you refer to it as "built-in"?
I have established an Ethernet PPPoE connection.
Is your Mac connected directly (via an Ethernet cable) to a DSL modem?
I'm sharing my connection through my built-in router.
I asked you before to explain what you mean by "built-in router" but you haven't. Do you mean the "Internet Sharing" option in the Sharing panel of System Preferences?
My TCP/IP config is using DHCP with manual address input.
There are several programs where this type of thing can be configured. In which program and panel do you see that option?

Internet sharing has stopped working after 10.8.2 upgrade

Hi. So, for the past year, I've been receiving WiFi internet on my iMac, and sharing it via ethernet and sometimes FW800. Lately, mostly just ethernet. As of 10.8.2, this has stopped functioning. I have heard many rumors about internet sharing issues in the update, but it seems I am in the extreme minority in terms of sharing internet via ethernet rather than sharing it via WiFi.
For the record, what I have tried so far is, enabling and disabling all options, trashing preferences, creating a second administrator account on the iMac and trying from that one, switching multiple ethernet cables just in case, and even switching to a different wireless network (we have two in my home on different wavelengths). It's always the same: devices recognize that they're connected to the ethernet port on the iMac. The iMac recognizes it's connected to them. They can obtain their own IP addresses through DHCP, but they cannot, under any circumstances, actually connect to the internet.
Please help! I'm tearing my hair out over here, as this was crucial to my setup. Updates shouldn't work this way.

As with other situations where a window is not visible, it is likely just off-screen where you can't see it. If your main "Final Cut Pro" window becomes inactive (close, minimize, and zoom buttons turn grey) when you attempt to open the "Background Tasks" window, this indicates that the window is definitely opened, it's just offscreen somewhere.
You can solve this problem by forcing FCPX to gather up all of its windows without having to delete your preferences:
1. Attempt to open the Background Tasks window in FCPX,
2. Switch to System Preferences->Displays and change your display resolution,
3. Switch back to FCPX and verify that you now have your missing window back,
4. Switch back to System Preferences and change your resolution back to its previous setting (likely the "Best for display" radio button).

Internet Sharing keeps needing to be reset

Hello-I am using internet sharing to allow my iPhone, iPad, and 2nd iMac access to my cable internet connection. This certainly works fine, except lately, I will try to connect to the internet on my phone, and the web pages do not load. I can fix it by going to internet sharing preferences, turning off sharing, and then turning it back on again. This is annoying, because I'm usually in the other room when I want to use the internet on one of these devices. Is there a way to fix this? I called AppleCare, and they just had me restore from Time Machine backup, which didn't resolve the issue.

Hi gallaghm,
That's not good when you notice the drop in speed is your computer connected wirelessly or wired? If it's wireless it could be a problem with the wireless channel and resetting the hub is changing this for you. Check out this link and let me know if this helps.
Thanks

Detect users when using Internet Sharing?

My wireless died months ago, so I've gone back to a wired ethernet connection for my TiBook. When my friends come to visit, I turn on my AirPort card and activate Internet Sharing. This all works well and good, with no tweaking necessary. Thank God for Apple, Inc.
The problem is, I would like to monitor who is using the internet connection. If my neighbors (I live in a condo) are leeching my access or, worse yet, attempting to hack my laptop, I would like to know about it. I can't find any app included in the OS to monitor such connections (which, btw, seems really insane, since this sharing functionality can be flipped on by clicking a single button). Any ideas on what software I should be using?
Thanks.
TiBook G4 Mac OS X (10.4.8)

Nice try, but fails if they simply assign themselves a different network address, or if they get one from DHCP. No, since his laptop is now effectively the wireless access point and NAT routing device, the thing to do is check the arp cache. I'll bet there are third-party programs to do this, but being a homebrew kinda guy, I'd write a script like:
<pre>
#!/bin/bash -l
currarp=`arp -a`
if [ -f /tmp/arpcache ]
then
anychange=`echo "$currarp"|diff -q - /tmp/arpcache`
if [ "$anychange" ]
then
change=`echo "$currarp"|diff - /tmp/arpcache`
echo "someone new is on the network $change"|wall
echo "$change"|syslog -s
echo "$currarp" > /tmp/arpcache
fi
else
echo "$currarp" > /tmp/arpcache
fi
exit 0
</pre>
And then make it execute every minute with cron:
$crontab -e
(add a line to file with $EDITOR:)
* * * * * /path/to/script
And then as long as I've got a Terminal or xterm or other cli window up, I'll get a notification if there's any change on my network. Since my laptop is the access point, anybody connecting to the network is going to be in my arp cache, so we can examine that for any change.
It's not a pretty script, just whipped it up, but it should prove the concept.

Nokia 520- Internet Sharing Issue After WinPhone 8...

I recently updated my Lumia 520 (AT&T) to WinPhone 8.1 OS. Since the update was installed, I am unable to turn on my internet sharing (mobile hotspot). I receive the following message on the screen, "Connect not shared. To enable tethering on this device, go to att.com/mywireless or dial 611." I have spoken with AT&T technical support on several occasions and they do not see an issue with my plan. I also have a second device (another Lumia 520) on my plan that was currently running WinPhone 8.0 and successfully sharing internet as a mobile hotspot. Today, I manually updated the OS on that device to WinPhone 8.1 and as expected, the internet sharing functionality stopped working after the update.
I have looked through various message boards and posts related to similar issues, however I cannot find one that is directly attributed to the WinPhone 8.1 update.
Any ideas or assistance would be greatly appreciated.

Thanks Abi99
After I pulled the battery to get the product code, the error message when I try to start ICS changed to: Connection not Shared. Internet sharing isn't currently available
I am still on AT&T. However, I ported the number (not the device) out to T-mob and then back to AT&T 3 weeks later. I used the 520 on WiFi in the interim 3 weeks, and during this time, it received the 8.1 update notification, and I installed 8.1.
Which connection profile is choosen in Lumia » menu » settings » celluar+SIM » SIM settings?
Active network: AT&T
Data Connection: On
Don't Roam
SIM Settings: SIM
No data under APN settings (all fields empty)
add internet APN » APN wap.cingular » save » power off » power on: Does it work?
Tried, doesn't work
add internet APN » APN phone » save » power off » power on: Does it work?
Tried, doesn't work. But after this change, the error messgae goes back to the original one:
Connection not shared. To enabled tethering on this device go to ; http ~ or dila 611

Unreliable Internet Sharing in Leopard

I am having a lot of trouble when attempting to share an Ethernet based Internet connection via the AirPort on my Mac Book Pro. The connection does in fact work, but is very, very slow and unreliable -- especially for email. Web browsing is sort of OK, but fetching email via POP and sending via SMTP barely works.
(The machine that is sharing the connection is a 12" Powerbook. Both are running 10.5.1, and Internet Sharing was totally fine when they were both running 10.4.)
One curiosity: if I open a terminal window and run a ping command on the Powerbook (the remote machine getting it's connection via the AirPort, not the one hosting the connection) things do improve; not markedly, but enough to get some work done.
I am wondering if this is a firewall issue at all. I saw on some post that one part of the new firewall looks at the time between incoming packets, and considers those spaced too far apart as "new connections." I don't know if that's true... but it might explain why keeping a ping going improves things a bit.
Anyway, there's enough posts on the net to indicate something is rotten in Denmark when it comes to Internet Sharing on 10.5; but I did not find any answers to help me with my particular situation.
Any ideas on how to fix this?
Thanks in Advance,
Mark

I too am having almost identical problems. My configuration is a MacBookPro (OS 10.5.1) getting an internet connection via a Verizon Wireless broadband Express card which works fine insofar as the MacBookPro is concerned (cable modem or DSL is not an option). I am trying to share this internet connection via airport to my wife's MacBook (also OS 10.5.1). After initial start up I can receive web pages on the MacBook OK, but after several pages of satisfactory operation pages start loading slowly until finally they completely stop loading (Loading X of Y items or Contacting XYZ). At this point all internet functions on the MacBook (mail, software update) are inoperative. Sharing works fine with a G5 iMac, G4 iBook and PowerBook (all OS 10.4)
I have spent hours on the phone with Applecare & in the Apple retail store with technicians, to no avail. Assuming it is an OS 10.5 issue, I hope a fix is forthcoming quickly.

UTorrent, Internet Sharing and Port Forwarding: Horrid Trifecta

Every good question has a couple of miles of back story, so here it comes:
I bought a Windows PC recently, and one of the first programs I downloaded was uTorrent. I have an iBook G4 running 10.4.8, but I have no wireless router, so I thought I would use internet sharing to get my new laptop off the ground. Everything connects great, internet sharing is wonderful on the web, but then I use uTorrent and notice that I'm uploading at nearly 3 times the speed I'm downloading, even when I only have 12kb of a file. I then notice the small icon at the bottom of the application that looks like a warning flag that my computer is confused, and I figure out that the problem is my new laptop has no ears, or rather, no listening port through which uTorrent can increase the speed of my DOWNloads. Further searching reveals that the traffic on the appropriate port is not getting through, hence I try to figure out how to manipulate internet sharing into forwarding the appropriate port range. I found Brickhouse, or as it is now known, Flying Buttress, but the program is remarkably confusing (to be perfectly honest, I'm not that bright). I cannot get FB to forward the port, no matter how hard I tried (every time I clicked Start IP Sharing, the it wouldn't work). So I can't use FB. I thought I would be clever and create a network on my Windows PC and share it with my iBook, but apparently my iBook refuses to share the Windows internet.
So now I am stuck trying to figure out how to get this Windows PC to receive traffic on TCP/UDP ports 10000-65535 through my Mac. To be honest, I really thought that the Mac would easily be able to forward the ports (is this in store for Leopard?), and I was a little disappointed the whole thing was so frustrating, but then I tried to setup an ad-hoc network on the Windows PC and realized that my Mac is still FAR easier to use, despite is insufficiencies.
So, long story short, I need help forwarding ports through internet sharing. If you can help me use FB, that's great, but to be honest, I would like a cleaner solution if possible. So my question is: How do I get my Mac to share port traffic with Windows if it is running internet sharing?
iBook G4 Mac OS X (10.4.8) Other Computer: Windows XP, other specs available on request

I was hoping more for a permanent solution that doesn't cost $100. Did I mention I'm in China? That program seems great and all, but I have the same technical difficulties I've had with FB. I can get the thing running and still have an internet connection on my machine, however, the port mapping or port forwarding or whatever you wish to call it doesn't actually work. These programs make it very difficult to understand what's going on; I checked the IP Address on my windows machine and used it as the actual address for the port I wanted to forward, I applied the settings and absolutely nothing changed on the windows machine. I went to portforward.com to check if the port was forwarded properly and still no response. This will sound stupid, but when I hook up the windows machine to the router through ethernet, it works perfectly, no forwarding required, so it is essentially my mac that is blocking or absorbing the intended traffic, but if I hook up the windows machine to the router, I have no internet for my Mac (I'm not sure if that's a problem with my Mac or with ICS). Can you explain to me how to use this program to forward ONE port, and ONLY forward one port (or a range of ports would be even better) without all of its inane firewalling that blocks all the internet traffic? Or am I just hopeless on this issue?

Can I use iPod Touch Wifi & Airtunes,without switching off Internet Sharing

I've got an Aiport Express connected to my stereo to stream my music library via Airtunes. It is away from my computer and does not have an internet connection hardwired to it. I would like to be able to use my iPod Touch to connect to the Airport Express, which would then wirelessly connect to the Airport Card in my mac, thus allowing the Touch to share the internet of my main computer.
Currently I can connect my Touch to the Airport card in my computer by turning on Internet Sharing, but when I do this, I lose the ability to stream my music to my Airport Express.
Can I somehow configure to stream music from my base computer AND surf the internet on my Touch via the Airport Express' wifi connection?
Thanks for any help!

Thanks Scott, Was thinking that might be the case, but was hopeful.
So, if I accept the fact that I can't use Airport Express to share internet that way, how about this related issue? I can connect my Touch by wifi to my computer's Airport Card by turning on Internet Sharing. However, when I do this I can no longer stream music from my computer's iTunes to my Airport Express connected to my stereo. The remote speakers disappear from the iTunes selection box. In order to get them back, I have to turn off internet sharing. And then Touch wifi stops working. Is there a reason that only once function would work at a time? Or do I have something configured incorrectly?
Thanks!

Sharing behind Internet Sharing NAT

I have a product demonstration that will require the internet being shared from my cell to two devices via ethernet. One is hard-wired to the physical ethernet port. The other is a virtual machine configured to look like a separate device on the network (VMWare Fusion 6, not that it matters). This is the only hardware I'm allowed to bring into the facility: phone, laptop, and the one physical ethernet device.
From a topology standpoint the network would look like this:
[Internet] -- [4G -- iPhone -- tethering wifi] -- [wifi -- MacBook Pro via Internet Sharing -- ethernet] -- <two devices, A and B>
I'm attempting to use the Internet Sharing-configured NAT on the ethernet port like a typical consumer router: 1 WAN port, 2 LAN ports.
At this point, enabling Internet Sharing allows both devices A and B to connect to the internet. However, devices A and B cannot ping one another.
I've been digging into PF and 'pfctl' but I'm not seeing how to allow traffic between A and B. It's as if the virtual bridge setup by Internet Sharing is unable to act as a switch for the "local" side of the NAT.
Does anyone know how to enable this functionality of Internet Sharing to allow A and B to communicate on any port? Or perhaps have a different solution?
Thanks for any help.
Thomas

Happy to hear alternative ideas to this one... This is a goofy fix:
In System Preferences, be sure you have disabled Internet Sharing before trying this.
1) Navigate to the System Preferences -> Network and click the + to add a new interface. Make it ethernet and give it some name.
2) System Preferences -> Sharing -> Internet Sharing -> Enable whatever your internet-connected interface is to hook to "both" interfaces labeled Ethernet (despite different names, both showed as "Ethernet" for me).
3) In VMWare Fusion, choose to bridge your VM's network interface with this second, fake, Ethernet from #1.
4) Boot the VM.
What you should see is that the VM still gets assigned an IP address, but the configured NAT that provides the Internet Sharing ability now can see and route between two connected interfaces. Otherwise it seems to think the single ethernet is exactly 1 device despite there being two MACs using it.
Cheers!
