Discussion around issues in Catlina MacOS

Esteemed Contributor II
There has been a lot of chaos on Catalina MacOS and its interaction with networks that have deployed Ruckus products for wireless service.  Issues are being seen in current Catalina MacOS that did not appear in earlier releases of MacOS: Mojave, High-Sierra, etc.

TAC managers have asked that we share information with our customers.

It is recommended that Macbook users use 10.15.4 who wish to use Catalina OS or have got an relatively older version of Catalina MacOS: namely 10.15, 10.15.1, 10.15.2 or 10.15.3. Apple has fixed a variety of bugs including but not limited to Wi-Fi, Safari stop responding when attempting to use Apple Pay, HSTS enhancement etc.

Apple has released beta version of 10.15.5 and it will soon be available officially on their website.

Some of the useful URLs on issues encountered with Catalino OS are:






Please note that Catalina is true 64-bit operating system and Apple has asked all the users to use 64-bit version of those applications. Please read the following URLs for further information:



Quotes on 32-bit applications:

“Apple first announced that it would ultimately wind down support for 32-bit apps more than a year and a half ago, when it began pushing alerts to macOS High Sierra users that 32-bit software was “unsupported.” The apps still worked, but with Catalina’s official unveiling back in June at WWDC, Apple made the eventual discontinuation official. With the launch of Catalina, 32-bit apps no longer function.”

I have an unleashed network with R610 + 2 x R310 that drops Zoom meetings on a new macbook pro. Could this be the issue, or do I need to raise a ticket with support?

It is recommended that Macbook users use 10.15.4 who wish to use Catalina OS.

And/But I have found further information,
Apple has made some further announcements: latest MacOS isCatalina: 10.15.5. It has some interesting features and fixes, please read ityour leisure:

// Apple releases macOS Catalina 10.15.5 with newBattery Health Management feature

//What's new in the updates for macOS Catalina

It may be that in few weeks 10.15.4 will be inaccessible...

What's the current recommendation on this. We are working w/coworking spaces and we can't just ask random people to downgrade, especially with the "it works everywhere else" response we tend to get.
