I’ve been having trouble uploading pics on my 13” MacBook Pro mid-2012. Probably 2-3 years ago the SD card input slot quit working and I took it into the Apple store and they said a new mother board would run about $300, but I could get an inexpensive card reader and plug it into the USB port. This worked ok. But now I can’t even upload thru that card reader, or even a direct connect with my Nikon point n’ shoot nor can I upload pics now from my iPhone 7. A new 13” MacBook Pro runs about $1160 with tax at Best Buy and I can probably string out the payments for a year or so with 0% interest. I like the operating system I have now which is El Capitan. Is it worth $300 to get a new mother board or is my MacBook becoming an antique and I’m better off just biting the bullet and replacing it? Thanks.
