 Hi Ronni - I was hoping you’d come on board.
 
 Maybe if I’d “Saved the Attachments” when right clicking on them when the 
 icon first appeared that would have solved the problem as they would have 
 been saved to my hard drive. But I can’t do that now - there’s nothing I 
 can do with the 
 
 The files are pdf ones.
 
 Yes, the email I’m referring to was from a Windows machine, but most of 
 the emails I receive with attachments are from Windows machines and this 
 only happens with some of them. 
 
 I’ve searched the web many times over the past few days but don’t see any 
 reference to the problem. 
 
 Cheers,

 Clicking on that does nothing at all. 
 
 How can I re-open the attachment?
 
 Any help would be appreciated.

Re: Wireless band choice

[Ronda Brown]

Sorry Neil, I had a typo error in my previous reply it should have been MCS  :(

Yes higher is better!
MCS Index - The Modulating and Coding Index of the connection. This number 
correlates to the protocols used to encode the radio signal. The higher the 
value, the better.

I am on NBN FTTP & My Plan is 100GB + 100GB + 50/20Mbps connection 
But I don't get regular download speeds of 50Mbps.
My Router is a  3TB Time Capsule I have directly connected to the NBN 
connection box on my inside wall upstairs
All computers, 1 computer media server, iDevices, Apple TV, printers run 
wirelessly. 
The computers & printers are downstairs (which is Limestone walls), Apple TV 
upstairs & iPhone & iPad anywhere & everywhere :)

Re: Wireless band choice

[Neil Houghton]

Hi Ronni,


Thanks very much for that ­ it may take me a little while to process it all.

Option click on Wireless Menu for me does not show Noise (presumably because
i¹m still on 10.6.8) but with your tip, I can now find it in System
Profiler.


Looking at your figures you obviously have a better network connection than
me ­ but maybe less intervening internal brick walls than my 120 yr old
Albany cottage  ;o)

Also, from the comparison, I take it that for the MSC Index that higher
numbers are better?


At the moment, I am back to my old modem/network setup ­ whilst I get a UPS
to cover my new modem and phone ­ but then, when I get a chance, I will take
the laptop around a few different spots and compare the figure on each
nettwork to get an idea how the walls attenuate the signals.


Cheers

Re: Mail problem

Thanks again Ronni.  After about 3 hours of downloading and re- installing 
Sierra, all now appears to be working fine.

 Hi John,
 
 A couple of questions first:
 A] Is this since upgrading from OS X 10.11.6 to macOS Sierra 10.12? or 
 updating macOS Sierra10.12 to 10.12.3?
 B] Do you receive any error message as to why Mail quit?
 C] Have you tried Restarting your MacBook Pro after Mail Quits, then 
 launch Mail right after you restart?
 
 I would first suggest you “Try A Safe Boot”
 
 To perform a safe boot, follow these steps:
 1. Start or Restart your Mac.
 2. Hold the Shift key immediately when you hear the startup chime, press 
 the Shift key and hold it down until the gray Apple logo appears on the 
 screen.
 3. Release the key when you see the gray Apple logo
 
 Your Mac will complete the startup process, which will take considerably 
 longer than usual. 
 You’ll eventually see the words “Safe Boot” on the screen—possibly within
