How does the RC appear overall? Would you say it's stable and ready to be the final shipping version of Sonoma?
A few tiny bugs here and there.
When I select an item on the Desktop sometimes I can't open it or delete it. Have to select again or command-tab again. This is the same app focus bug that has been in earlier betas.
The side bar on the Stocks app still has a mind of its own. It scrolls up when I scroll down. It scrolls up when I select a ticker. This bug has been around for about 3 years. It might be related to Wacom tablet.
Also, using a Wacom stylus to interact with the widgets on the Desktop is fidgety and sticky. Those widgets can accidentally be dragged. Apple need to make it so that a user needs to hold down a widget for 2-3 seconds before it can be dragged, just like it is on iOS/iPadOS.
