rMBP 2015 Wake Reason: ARPT (Network)

I spoke with Apple phone support and escalated this issue--they linked to this thread and sent it up the chain to their network engineering group.

Good to know. Hope they really pay due attention to this problem and solve it. 😀

Today I put my MacBook 12" to sleep (closed the lid) and captured the Wifi communication between it and my router. Looking at the communication with Wireshark I noticed that the first thing the MacBook does after the unwanted wake up is sending TCP packets to IP 17.172.239.3 on port 5223.

After some searching with Google it seems this has something to do with the imagent App which is in some way responsible for FaceTime.

Can this be correlated with the wake up and perhaps even the "ARPT: Wake Reason: Wake on TCP Timeout" message in syslog?

Does anybody here have FaceTime disabled and is still experiencing the unwanted wake ups?

(If an Apple technician wants to have a look at it, I can gladly provide the pcap file with the logged Wifi communication. Just contact me in case!)

Wow. Nice find. I did not disable FaceTime. BTW, did you run wireshark on your router?

I don't know if there are routers capable of running Wireshark, mine would definitely be too old and slow for this.

I used another Notebook running Linux, software from the aircrack-ng suite and Wireshark to capture and analyze the Wifi communication between MacBook and router. Perhaps also other people here can do this so we can possibly isolate the reason for this wake up problem.

Recently, I don't have that many wake reason for TCP stuff. But it comes with XHCI! More importantly, I don't have any usb ports in use. Seems Apple is having lots of problems with sleep and wake.

I seem to be having a similar issue. I updated my Yosemite 2015 rMBP to the GM candidate and have been experiencing some strange activity while sleeping. Any time the mac is sleeping, it begins to heat up quite a bit, and there is nothing I can seem to find that causes it. It did not do this before the update.

A SMC reset does nothing and neither does a PRAM reset. I have fiddled with the power options to no end, yet I still can't fix it, and I've changed a few setting with the pmset command (and changed them back after nothing worked). I did find what I thought was a fix by disabling "Automatic graphics switching" in Power Saver options, and it worked for about a day, but soon reverted to its previous behavior.

I'm about at my wit's end here. I'd like to avoid a reformat and clean install if possible.

Here's a small sample of the repeating console message I get with 'syslog |grep -i "Wake reason"':

Quite strange. I believe most of the reporters here are using 13' MBPr or 12' NMB. For us, graphics switch is not an option. 😀 Maybe it has something to do with 15' model.

These are the same errors I receive after an initial TCP timeout error and the same symptoms, but I only receive them when connected to my home network--the office wifi does not return the same behavior. The only workaround I've found is to disable wifi before putting the laptop to sleep, which isn't a huge deal anyway as I have to toggle wifi off/on again when resuming from sleep anyway or the connection doesn't work.

I just tried turning off Airport, and it did seem to work. I'm not sure why I didn't try it before, but it is a working temporary workaround.

I turned off Airport at 8:20 this morning, and haven't had the same errors afterwards, though I'm still unsure of what "SleepTimer" is and why the HID is waking the mac. Oh well, It's not getting hot and it's not losing a crazy 10% battery an hour while sleeping.

What worried me the most is when I'd leave my laptop in my bag and come back to it overheating with both fans running--yikes. Hopefully Apple is able to resolve this issue soon.

Do anyone have Apple AirPort router or do everyone have this issue with 3rd party router? If someone have airport, please plug it in and test will the ARPT wake occur with that.

I got today email from Senior Advisor and he wanted me to export my AirPort base station configuration file for the Apple's engineers. Engineers red my previous logs what I sent for them and now they want me to gather more information for solving this issue. Too bad I don't have AirPort router..

They also wanted me to make AGAIN a clean install and repeat the issue with capture data (apple's diagnostic sw) running but I'll not install 5th time only for the engineers.. Senior also wrote in email that there's another way to test this and it is temporary disable 3rd party kernel extensions. I will probably try to disable those kernel extensions when I get instructions and see will it change this at all because I'm 100% sure the clean or re-install will not do nothing.

I don't have an AirPort router but use a third party model. So I still don't think this wake up problem has something to do with a certain router model.

What does Apple want with the AirPort base station configuration? I also don't think the problem arises because of a "wrong" router configuration.

What happens on the network while the MacBook is sleeping (or should sleep) I already tested by capturing the Wifi data. See my post a few days ago.

Does anybody experience screen lit up and mac wake up when new iMessage comes in. I had already disabled power nap feature.

Agreed. There is nothing wrong with our home routers. For the record, I too have a non-Airport home router as its a combo router/cable modem provided by my cable company (TWC)--it is also their latest & greatest, capable of 300mbps speeds. This exact modem also worked on my previous rMBP without any issues (early 2012).
