Apple Event: May 7th at 7 am PT
I can't share anything from any device whether it's an iPhone or an iPad to my MacBook Pro 2020. I get a notification saying "airdrop from iPhone failed", and it appears "Declined" on the device I'm sharing from. I've tried turning off Firewall, having both bluetooth + WiFI turned on, I have tried switching Bluetooth and wifi off and then on again, I also tried rebooting devices but nothing seems to work!
MacBook Pro 13″, 11.7
Just checking, do you have both WiFI & bluetooth enabled on both your iPhone/iPad and your MacBook Pro?
What version of iOS is on your iPhone & iPad; and what version of macOS is on your MBP?
Is Personal Hotspot turned off? (It should be off.)
For further detail about enabling Airdrop see this KB article -> How to use AirDrop on your iPhone or iPad - Apple Support
If you want help, please answer the same questions I originally asked the OP. Without any specific details there is no way anyone here can help you.
The same thing has been happening to me, from my MacBook Pro M3, keeps saying my iPhone 15 pro max is declining the air drop when it doesn't pop up with anything, its seriously annoying.
