MacBook wifi keep turning on

So if you turn off wifi does your ethernet internet turn off also? Because if that is the case then you could just go to settings…

I am having the exact same problem. When I turn my machine off then on, (sometimes I need to do this twice) my machine turns on my WiFi. Was this issue ever resolved and if so, how?

Thanks in advance for any help.

Some additional information.

This only happens to me when I turn the machine off then on again (I never use Restart). I also tried it with my Ethernet connected and without, and the problem is the same. I then turned off the option to restart running programs on the shutdown screen, but also had no impact on the problem. Scanned for Malware too, came up clean. My machine is brand new. My old 2010 MBP running Yosemite and as of last week El Capitan never does this.

I have a ticket open with Apple and it is now with their engineers. These postings have also been put into the tickets, so that they know that it is more than just one machine now. Like you, I mostly use Ethernet at home (faster), but do use WiFi every once in a while. Wonder if the problem is more widespread, but few noticed it because they always have their WiFi on?

Update. Apple Engineers have now been able to reproduce the problem. This means that they still need to figure out what is going on, but when they do, the fix will be placed in an OS update. It may "not" be listed in the update's details, since they believe this is only impacting a small number of users.

We shall see. 😉

Still happening for me with 10.11.2 and I am on MacPro trash can.

I have a MacbookPro which has been fully updated to 10.11.3 and I have the same issue. I will turn on the computer and find that my wifi has been turned on. I rarely turn wifi on as I have a faster LAN connection I use everyday. This is an odd issue. The fact that Apple engineers several months ago stated they would resolve this issue in a new OS release but NOT make a note of the issue regarding update details seems a bit strange. I think this issue affects many more computers than they think. Please fix this soon Apple!

Happening to me too - Mac Pro trashcan with OS 10.10.5.

This has been happening for a long time, annoying to say the least! Though it does not happen EVERY TIME I turn on my Mac Pro, more like every 5th time or so.

Nope - I was wrong - WIFI comes back activated EVERY TIME I turn on the Mac Pro.

I even deactivated Wifi from the network settings page of the system preferences, it still comes back active after power-on.

My Macbook Pro is experiencing the same issue. Has there been any update on this automatic wifi connect?

Me, too. Or: Me, three. Or whatever arbitrary number: My MBP 11,2 (Mid 2014) with El Capitan (now OSX 10.11.4) keeps turning on Wi-Fi during reboot.

I'm using my MBP mostly stationary in my office, establishing my network connection through a Thunderbolt Ethernet adapter. I have a Wi-Fi network available, and I definitely use it occasionally when I walk around with the laptop. However, most of the time I simply turn it off.

I'm one of these oldtimers who tends to shutdown the computer at the end of the day (please spare me comments like "you're using it wrong" 😉), and I wouldn't expect Wi-Fi to turn back on magically during reboot the next morning. I don't really have too many security-related concerns about it – but more about safety: When I'm booting up my MBP on a plane (as rarely as this might take place), I don't really want it to switch on Wi-Fi without my given permission.

… Interestingly enough: My old iMac 12,1 (Mid 2011) at home which is on corded Ethernet at all times does not share the problem: I can switch on and back off Wi-Fi, and it won't be activated during reboot.

My gut feeling tells me that El Capitan really, really, REALLY wants to be on-line, and as the Thunderbolt Ethernet comes up later during the boot process, it simply activates Wi-Fi unaskedly. This is similar to my iMac turning on its formerly deactivated Bluetooth when no corded keyboard or mouse are connected during boot, simply to be able to search for Bluetooth input devices.
