My mid-2010 Mac Book Pro is about to get sent back to Apple for having a dead SD card reader. Both of the new 32GB cards I tried in it do not register. They both register just fine in my MacBook Air (late 2011).
This MBP must have been made on a bad Monday for someone... it originally arrived with a dead power port

so it went back for that. Then it went back for bad WiFi (not just connectivity issues, but throwing errors to the log)

and they replaced that. Then it went back for bad optical drive

and they replaced that. Now the SD reader

which I sure wish I had thought to check out before I sent it back for the optical drive.
Meanwhile on each repair trip the rep has assured me that they completely check out the machine before sending it back. No longer sure what "completely check the machine out" actually means. Maybe it means "it boots" in which case saying it's a "complete" check is way past overstatement.
Going to rename this mid-2010 baby "MyLemon" pretty soon. I have never before had this kind of experience with a Mac and I've been buying them and driving them into the ground since 1984. Most of them NEVER went in for a fix, lasted at least five years and even then were good enough to give to a neighbor's kid after a drive wipe and fresh OS install.
I'm almost ready to chuck this machine into kitchen recipe server status when it comes back, and get a refurb late 2011 2.8GHz i7 MBP to have a more reliable (maybe?) workhorse. I've been thinking about that lately anyway since I don't think I want an rMBP. So if I go that route and the late-2011 MBP doesn't work out better than this mid-2010 seems to be doing, I don't know what I will do. Stick with the Air line going forward, maybe. I'm just as mad as a hornet right now. I feel sorry for the next person I bump into today if I don't get a grip and chill out... heading off to make a tall iced coffee!! Sorry

for the drift from thread topic to overall rant. Thank goodness I got AppleCare on the machine.
