NETGEAR USB Control Center utility for MAC OS X El Capitan

Just thought I might report on what happened when I sought the beta.

Only able to obtain a support phone contact number (from Australia) via a website that gives these for a large number of companies. The Netgear website seems to not publish these.

Hours (literally) spent on phone trying to get through to Support and then to get them to understand what they needed to do (just give me access to the beta). They did no know anything about this problem and the first 2 could not even locate the case number we were given by Elaine. They reminded me that my 90 days of free support had expired for my router (one of four Netgear routers I have) and one even asked if I was interested in purchasing support! Also, they were avoiding passing me on to Level 2 support even though I kept requesting this. Spoke to 3 people (plus 1 Supervisor in background) before really helpful Gokul (who knows Elaine) phoned me back and then passed request on to Level 2 Support.

Was emailed a link to an Agreement (including NDR) I had to agree to. Then sent a link to the download. This produced a .rar file (rather than using zip which is native on macs) which I had to get a program to unpack (used "The Unarchiver" from the App store).

Executed the installer, but it seemed to achieve nothing. Ran uninstaller and installer again, but no result. Notified Level 2 Support.

No problem on my system as a result.   I run latest Sierra (10.12.1) on an iMac (27-inch, Late 2012).

Suspect "beta" is more like an "alpha".
