It’s actually impossible to attach pictures, they always are displayed in the mail. Also, when you drop a file into the message it’s not “attached” in a “attachment box” but their icon is actually floating anywhere you dropped it in the message.
Again the “insane attention to details” while in 2024 attaching a picture or a file to a message in Apple Mail.app macOS is an absolute nightmare. One example amongst many many others. It’s cool, very cool, but I wouldn’t call Apple this way while there’s so much awkward choices to be fixed in their software.
I’ve been using it for many years, I think it’s one of the oldest alternative mouse driver for Mac. Highly recommended to those who want to avoid the bloated (and now AI powered, for whatever it means) Logitech software.
I’m also a tech enthusiast but I change my iPhone every 4 or 5 years. And it may be the issue here, there’s not that much incentive to switch from an iPhone to the next one except if you are an Apple fan boy, thanks to the awesome upgrades support. Hope they won’t “fix” it.
