Apple Mail has been a relatively reliable app on macOS for a very long time. Well, that wasn’t always true, but it’s a work horse one way or another. For the most part it does what I need (except searching emails, but for that there’s InfoClick).
One aspect of Mail that Apple seems eager to tweak every couple years is the sidebar showing your accounts and inboxes. I think the Mail sidebar on macOS Big Sur is actually relatively straightforward considering some of the confusing messes Apple Mail has showcased over the years. But let me complain about this for a hot minute:
The “On My Mac” area has always been reserved for emails that are only stored locally, i.e. those not stored in the cloud. How the heck am I supposed to tell all these Trash folders apart? I have several accounts with local storage and there’s no labeling to disambiguate them. I’m forced to blindly click between the folders to stumble on the right one.
This is a tiny annoyance, but I still hope it gets improved. Maybe in macOS Monterey, which is likely to be finalized soon. We should know more about Monterey’s release date after the Apple event next week.
