My partners Mac book pro died of the age old problem,the suicidal glass of liquid H20 that dived of its own free will across her laptop, causing said mac to go to that great mac store in the sky.
After many varied techniques of drying and with every appendages crossed finally approached the genius desk at local mac store to find that even Dracula could bring this body back from the dead.
Mother board gone and various other organs deep kentucky fried.
Store unable to suggest ways of getting data of hard drive except by replacing entire inner workings at the cost of $2000+ and then no guarantees.
So bough brand new pro for $1600 with all the bells and whistles.
And tripped the light fantastic to your friendly ifixit video archive to learn how to retrieve data.
Easy as ordering a large slice of lemon pie, following my handy Ifixit video and with my handy $13 purchases at the ready, which arrived 3 days after ordering them in Australia from the states, faster than the man of steel can change in the oldie telephone booth.
Repairs and recovering of full data took 10 mins. And a very happy partner. And a host of spare partners for my own pro, long may it live.
Never give up the ghost in the machine, and what ever the Apple Wizards recommend always double check from a separate independent source, love the product not so sold on the after service.
Ya got to love Ifixit
