I bought a used Magic Mouse (the battery version, not the rechargeable one) but it won’t right click at all. After looking there seems to be a big dent under the right click area. It doesn’t show up well on camera but it’s there:
Can I safely fix or remove it? Thanks
Ouch the aluminum shell is bent up so its stopping the plastic part to go down. You might be able to bend it back wedging between the surfaces carefully prying. If you can see of you can disassembly it review this for an idea what’s need Magic Mouse Teardown Otherwise you’ll need to get another, sorry ;-{
