Hello! I just gained my new iMac iMac, 27-inch, 2.93GHz Core i7, 8Gb, 1Tb+256GB SSD, ATI 5750 with this type of SSD:APPLE SSD TS256B. And now I want to deactivate atime (so to activate noatime) and I can't do it. Well, I have done everything like written here http://forums.macrumors.com/showthread.php?t=863807 but after typing mount nothing have happened I didn't see noatime. Who knows the solution of these problem? May be in last iMacs we can not activate noatime cause OS X doesn't need it?
