Please can we use third party Bluetooth mice with pre-boot MacBook/MacBook Pros encrypted with FileVault. I’m not happy that only Magic Mouse mice work during this part of the boot process.
Last year I posted a blog which expressed my frustrations with the system recovery process and non-Apple Bluetooth mice. Even with the Logitech Master 2S hooked up via USB, System Recovery would have none of it. That’s when I had to fork out £55 for the Apple Magic Mouse.
Speaking of pre-boot problems, the 2019 MacBook Pro 16″ appears to have issues with Apple’s own (external Bluetooth) Magic Keyboard during pre-boot. When I go to enter my account password to unlock FileVault, more often than not, some key presses aren’t registered in the input form. I have to press them multiple times to get them to register. Sometimes it’s so bad, I have to open the laptop lid to fully expose the built in keyboard and enter it there. That’s works okay – but I’d rather use the external keyboard wherever possible if I’m hooking the machine up to my external monitor. I’m pretty sure my 2018 15″ MacBook Pro didn’t suffer from this problem. Maybe macOS 10.15.4 will resolve the problem?
