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:
“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.”
