I was just downloading all transactions, and I have it set up to show the Connection Status (Update Summary) always.
Sometime near the end of the update, I saw 3 accounts in the sidebar got a blue dot, but when the update finished, only one blue dot remained in the sidebar. The screen had blinked, sort of, and two of the blue dots disappeared.
The Update Summary does show that 3 accounts were updated (with a total of 5 transactions between them), so from that I know which accounts were updated, but only one of them - the one that still has the blue dot in the register - shows any icon next to the new transactions. It's just a regular blue dot - a new downloaded credit card transaction.
I can guess by looking at the registers of the 2 other accounts that the Update Summary showed were modified, that the transactions in question were matches to the two halves of a manually input transfer from checking to a credit card.
I can confirm that guess in Quicken for Windows, which I am running in parallel as I test out the Mac version. For the 2 accounts in question, the Windows version is showing me the Downloaded Transactions review window, with the 2 potential transaction matches, one in each account, which currently are marked with the orange pencil in the 2 registers.
For the Mac, I've read that after auto-matching, these transactions should have been updated in the registers with blue pencils (meaning matched to manually entered transactions, but not yet reviewed).
Is there some setting on the Mac that in certain cases auto-reviews some types of transactions? I hope so, so I can turn it off! I want to review everything.
