That is not exactly a development issue, but more a Mac configuration (which may hide other problems ?).
I use a new MacBookAir with MacOS 26.
When I Airdrop from another Mac (15.7.8) the MacBookAir does not show any icon but a blank area, whilst other devices show their icons:
That seems an old issue with MacBookAir: https://www.reddit.com/r/macbookair/comments/1benu4o/blank_airdrop_icon/
Beside this, Airdrop works OK.
Just as if the MacBookAir icon was missing in some system file ?
Has anyone a solution ?
