Network Diagnostics app missing

God love ya for this Keith-- unfortunately I'm going from 10.10 (Yosemite) to 10.13. No problem using time machine to grab the necessary files... but in 10.10, there is no SetupAssistantFramework.framework. (There is the SetupAssistantSupport.framework). Is the necessary file /System/Library/PrivateFrameworks/SetupAssistantFramework.framework/Versions/A/ SetupAssistantFramework located somewhere else on 10.10?

I join in the outrage of Network Diagnostics being eliminated. Can't operate without it-- so if I have to, I'll go back to 10.10. (Yeah, missed a lot of upgrades. But got a lot of macs, all working as they should be-- exactly why I decided to upgrade tonight on this machine is becoming more of a mystery by the minute.)

Thank you for any insight you have-- and again, you should be knighted for these instructions.

You just saved me big time, Keith. I didn't think of what would happen when an update occurred without the ownership changes. Just made them. Thank you! Yeah, I know Net Assistant is a separate program from Net Diagnostics. As the information superhighway is a dirt road at best at this location, Network Diagnostics is used daily (some days, hourly), so I glommed on to that and in my glee that it worked, I didn't check Network Assistant. Just did, and the news isn't as good. Apparently the missing files do count there-- it doesn't work. But that'll be a problem later. Just having Network Diagnostics now takes a big thorn out of my paw. Rest assured I did make my feelings known to Apple-- in graphic detail. Here's hoping that our collective gripes will fall on sympathetic ears, soon. Thanks again!

Because some of us are not computer-savvy enough to handle all the suggestions already mentioned.

When my email accounts went down network diagnostics always solved the problem.

Why on earth is Apple so stupid as to remove this when they must know its value?

Apple are making things so complicated now that they are going to lose their long-time customers who bought

Apple because it was so much simpler than anything else.

Not so much now........

Hi Maria - Thanks for your reply and for encouraging me to try Keith's suggestion. I don't see the point of the Mail Connection Doctor without Network Diagnostics - so why they kept the one and got rid of the other is beyond me. Sometimes I think that Apple don't give any consideration to those of us who are not computer-savvy and yet there must be thousands of us. I always hoped they would bring out a laptop for simpletons but it wouldn't be at all sexy. And having just bought a "new" iphone 6S with a battery that last only for a day even when not in use, I think it is time that they put customer satisfaction ahead of their profits. But would I buy anything other than an Apple? Probably not! Thanks again for your encouragement. I shall take the plunge through gritted teeth and hope for the best.

Hi Scouserboy. You are talking to the Village idiot when it comes to computers. It took me years to work out what cut and paste meant - I live nowhere near an Apple store so have tried to keep things as simple as possible. Keith's instructions were double dutch to me which shows just how ignorant I am - and to be honest I chickened out! In the time since posting on here and having a "chat" with an Apple advisor (which is always a nightmare) my BT account came back on line. My "Chat" advisor told me she had no idea why I could not get Network Diagnostics and would I like to leave a report for the engineers? I bet they are engineers! So I filled in the form and said others on Apple Support were complaining about this and why could it not be reinstalled? I don't expect to get an answer but if I do I will post it on here. There must be other cowards like me who would be happier if Apple put things right! But I am grateful for your help. If you knew how little I know of my macbook pro you would suggest a return to paper and pencil!

Thanks again and a happy New Year to you both.

I suppose that we can try letting Apple know that we are unhappy about this, and in particular those of us who connect via ethernet.

Amazing. you have a TimeMachine that appears to still be working.

Agreed - the subtle but continual reduction of diagnostics tools in OSX which has been happening for years is only making Mac less appealing 😟

I am very frustrated with the lack of Network Assistant.

How can we communicate this to Apple?

Do they really care?

What if you are not using Wifi, anyway this has already been mentioned, and there is a solution for those that have a Sierra backup.

Why can't people read the whole thread? It's already been stated several times in this thread that WiFi diagnostics is NOT the same as Network Diagnostics!

Have you read through this discussion, this has all been said before and is not in itself a solution.

Another one of your pointless contributions.

Mail Connection; really tygb?

Do you even know what the discussion/thread is about? Did you ever even use the Network Diagnostics tool?

Please remove your head from the clouds.

Used it before see the thread OS X Sierra wifi/internet issues

Dude. Do you mac, bro? There is nothing of what you describe. Did you even update, bro?
