Is it a lot of work to open up the computer in order to take out the drive and put it in a 2.5" USB enclosure for testing? And will I lose any warranty by opening it up or is upgrading the RAM and hard drive what Apple would consider "user-serviceable"? Replacing the drive with an SSD is something I plan to do some time, but prices are still high if you want a reasonably large one, so I'm holding that off (I know some people replace the DVD drive with a hard drive bracket where they put the old and large (mechanical) hard disk drive, then put an SSD where the hard drive used to be, but I think it's nice to have a built-in DVD player, so it's not for me). I actually bought it in 2014, but that's still 3 years so it's a good idea to check the drive in an external enclosure first.īut I highly suspect it's the cable because it's been slow as molasses ever since I can remember.
I may upgrade to an SSD later on, and as long as this bugger keeps running the current macOS, it's more than enough for my needs. In the end, they covered the new cable and all labor, and I paid less than eighty bucks for a new drive. Although the cable was covered, the drive wouldn't be, and I'd have to pay for a new one. They were probably minutes away from calling me to tell me that, after opening it up, they checked the drive itself and found that it was failing as well. I'll get started on a work ticket to have it replaced." I approved, and she took it into the back while I left to go shopping.Ī couple hours passed without contact from them, so I went back to see what was up. When the Genius plugged in their diagnostic tool and started its run, the Mac started beachballing, and she said right away, "Usually, on a 2012 13", if it does this, it's the drive cable going bad. I took it to the Apple Store a couple days later.
Later, when it started getting weird again (especially taking FOREVER to boot), I booted into recovery mode and ran Disk Utility again - but it found no errors, saying the disk was fine. I made backups after rebooting normally and ran regular backups from then on, but it seemed to run fine.
