Foolishly I tripped over my audio cord and it snapped off leaving a bit at the bottom of the rear socket of my mac pro..I have heard horror stories, can anyone advise? thanks
Happened on my daughter's black Macbook about 18 month's ago. Apple genius said they could fix that for $420. She and I did it ourselves based on iFixit disassembly instructions and a hemostat.
Coat the end of a large paperclip with crazy glue. Not so much that you have a drop at the end, but a smooth coating so it doesn't drip. Carefully glue the paperclip to the piece stuck inside. wait a couple hours and it should come out glued to the end of the clip.
good suggestion with the super glue... but I'd try to use the original broken end of the headphone jack with the glue instead of a paper clip (more surface area, should create a stronger bond)
Using a paperclip would likely mean you are less likely to push it out to the edge and risk touching the inside or sides of the headphone jack. Some superglue should work doing this .
