I just logged on to CT on my Mac (MacOS Big Sur 11.6) with my Admin userid using Chrome build 96,0.4664.93. I was able to download the tables in a report taken at random with no problems, exactly the same way I did on my regular Windows 10 desktop.
I hadn't used the Mac for a while, so I'm upgrading Chrome to build 99.something and MacOS to Monterey 12.2.1 and will repeat the test.
(later)
I repeated the test on MacOS Monterey 12.2.1 and Chrome build 99.0.4844.51 and the export to Excel worked fine like before.
