Apple M1 Mac mini. Big Sur, InDesign CC 2021, tables are SLOW
I've created a 6 column, 355 row table. No fill, default black stroke. I've created this same table, from the same data 100 times on my 2015 imac, running InDesign 2017 thru 2020. High Sierra was the highest MacOS on previous computer
When I copy a word or phrase (100 or fewer characters) and paste it into another cell, it is showing the thinking beachball for 15 seconds. I'm simply double clicking on 5 characters to copy, then clicking into another table cell to paste the word. Everything that I had previously completed using tables in previous versions was quick. The 2021 version running on Big Sur and the M1 chip is painfully slow.
We posted a Beta build with Native support for Apple Silicon a few days ago.
