Apple IOS 10

I have just discovered the problem, It would appear that my antivirus software needed an update and so would not allow any access to the internet following the IOS update. Updated the antivirus and now all is well. 

Why iOS 10 for a MacBook? Isn't that for iPhones and iPads etc. I thought the MacBook used macOS Sierra. 

I'd suggest ditching the antivirus software. If you are using NAT and a decent firewall it's really not necessary on macOS, providing you don't do anything too silly.

When switching from Windows to macOS many companies have ditched antivirus software. I can think of two major companies; one with ~380k employees, the other with ~180k who did this recently. Both are now about 80% Mac.

A solid network and regular software updates are a far better strategy on macOS.

I've never heard of anyone using antivirus on a Mac. The amount of problems they caused on my Windows years ago, I was glad to see the back of them when I moved to a Mac.

Sorry it is macOS Sierra 10.12.2 not IOS 10, my error thank you for correcting me.

I have read several reports in the past advising use of antivirus software for mac and in particular for internet banking, where would you stand with your bank if your bank account was compromised and you had no antivirus software installed?. I spoke with our local IT guru who we have used to resolve Windows problems in the past and whose opinion we trust. He advised that antivirus was still a good idea. I would rather have antivirus protection on board than have to resolve problems if my laptop gets infected.

What AV software do you use, Ken?

I used to have Norton antivirus on my Windows and upgraded it every year for 10 years. I had endless problems with it slowing down my computer, other issues and had many viruses and malwares. Absolute rubbish.

 Macs don't need it and there are many regarded articles/discussions that say antivirus can make the system less secure.

"Exploiting the vulnerability requires no user interaction. The vulnerability exists in a default configuration, and code execution occurs at the highest privilege level, if not the kernel itself. Security software necessarily requires high access privileges to operate effectively, though when it is itself insecure or otherwise malfunctioning, it becomes a much higher liability due to the extent to which it has control over the system. These software issues, combined with logistical and political problems in the antivirus industry itself, are making users less secure."

On my MAC I run the Sophos Anti-virus program. Just in case, Apple also release virus  protection code to protect the Mac. I run Sophos mainly to prevent any corruption being received and forwarded to Windoze users.

Here is an article published by Apple

http://www.apple.com/uk/macos/security/

so perhaps I am over egging it by using Sophos.

I've been using Macs since the 1980s, since the days of floppy disks. Even then, we were encouraged to use an anti-virus program as viruses, trojans and the like could be easily passed on via the sharing of disks.

Since then, I have always used an anti-virus software on my Macs at home (currently it's Avira, which sits quite unobtrusively in the background).

The fact is, Macs are vulnerable to "infection", as any connected computer is. The idea that they're not is rubbish. It's just that generally the Mac OS is less vulnerable than Windows and Apple tend to fix the vulnerabilities faster than Microsoft do; also, there are far more Windows machines out ther than Macs and virus creators will either be looking to make the biggest splash possible or exploit the klargest number of machines so tend to attack Windows.

The fact that the "Mac community" is more tightly-knit than the far larger, more diffuse and less aware Windows user base probably plays its part as well.

However, AV software can never be a subsituture for common sense and caution. Never open or download attachments from people you don't know, make sure your mail has a decent spam folder, ensure your ISP has decent firewalls, delete cookies and clear your cache regularly, have different passwords for sensitive sites, etc.

I had a small glitch after updating to OS X 10.12.2  After the first restart, I had noticed a few hours later that the time wasn't updating on the day/time clock on the desktop.  I did a restart, and then a bunch of stuff wasn't working (Chrome, Messages . . . ).  So I did a shut down, another restart, and all is back to normal.

An extra shut down / restart cycle can often be helpful.

It is called Avira and is a free download, it was recommended by our I T man.

Ken, I use Avira and it is always worth shutting it off temporarily when doing major system updates.

Thanks I will bare that in mind. 

Thanks Ken.

Last year there was a noticeable slow down on my iMac, I used Mac Cleaner and Norton and 4 very frustrating days just before Christmas it clogged up completely, I feared a virus. I made an appointment at Apple Store Christmas Eve. First class service, diagnostics said the drive was still good  (probably 8 years old), they wiped my  system,He set up a firewall saying after years of updates, some things not connecting, plus the use of 3rd party anti virus and Cleaner not needed. I was there after 6PM, cleaning crew came out, all the workers were wiping down the displays, I thanked them profusely and walking out said "Superior service is why I've  been a Mac owner for decades." The guys appreciated that, they were obviously enjoying their camaraderie. I also noticed that out of 10, 3 had disabilities, way to go Apple, always knowledgable and pleasant dealing with frustrated customers. 

Xmas morning was spent  getting all my preferences set and internet connected. Even a klutz like me was able to get it all back online.  Everything was on iCloud thankfully and haven't lost anything. It is rip roaring fast, he said don't use other software, it's not needed, and if you don't pay they leave the back end open for other hackers. If anything needs servicing bring it back, that's what we are here for.
