Doesn't work with new 2018 Macbook Pro 15.4
Have used this app for several years whenever I needed WiFi diagnostics. Its been good. But doesn't seem to work correctly on a new 2018 MBP 15.4" Works fine on my old 2014 MBP, both on Mojave. It needs to be updated for new Macs!
WiFi Scanner is Back!
A big THANK YOU to the developer for getting WiFi Scanner working again under OS X Mojave and a 2018 MacBook Pro. I've been using this app for years and appreciate the continued development. It's my go-to app for finding out what's going on in my surrounding WiFi environment.
DOESN'T WORK WITH MOJAVE (Feb 2019)
I want to second (or more) that this doesn't work with Mojave. Likely being blocked by Apple, but if not PLEASE UPDATE WITH A FIX.
I had a great WiFi Scanner IOS App many years ago that Apple disabled in later versions of IOS, and I paid $ for it. Was really handy when helping friends with their router setup, now have to carry in a Laptop, and now this doesn't work. Guess I'm going to have to dig out my old XP PC Laptop
Developer Response ,
Please enable location services. Apple requires this for scanning to work in Mojave. See app FAQ on website if you need help or email support.
With Family Sharing set up, up to six family members can use this app.
