"iPhone speaker wont play iPod audio, but will sound off ringtones."에 답변Had same problem- music playing through speakers did not work, but ringtones did work; music with headphones and bluetooth did work. I backed up, did a restore, and restored all previous data etc. That was it - it worked!
"Why is the fan so loud?"에 답변I had the same problem when I swapped out the HD in my imac 27" mid-2011 with an SSD drive. I believe the fan began running full throttle because it did not know how to process the temperature readings of the new drive etc. I searched online and came across this website - http://www.hddfancontrol.com (Parenthetically- I am not that tech savvy but I do not recall seeing or detaching a temp sensor or wire) I installed their program and have not had any problems since (it's been at least 6 months). Good Luck! Mike
