Let me start off by saying that i had 4 replacement mac pros when the 2009 models came out. Buzzing power supply. When i finally took it to the Apple Store the Genius there said there was indeed a problem, they apologized and finally sent me a working one. Now the applecare i bought, well never got transferred. They said its fine, no problem. So i got an email in September saying something about an applecare. So i thought great. Well i was doing some archiving and i checked the PDF compared it with the certificate i first got when i bought the applecare. Turns out the Applecare that got updated for the new machine (serial number) is only the base applecare for higher education. So basically i lost the full applecare plan which i paid extra for. Now the email was sent in September so i have a problem now. What should i do. I tired of all these. I mean talking with applecare for the replacement machines. Arguing over my applecare, and finally they still mess it up. I have had enough i mean how long is this going to go on for. thanks, any suggestions are welcome.
