i'm new here a rookie in the Mac world.

i own a macbook pro i5 late 2011 OS 10.7.4 upgraded with a Crucial M4 256 from a conventional 500GB HDD.

not very fast at startup but super fast shutting down.

don't know why but sometimes the color spinning wheel appears and the mac freezes for a few seconds (sometimes i could swear around 10 seconds but i nerves counted...)

it started to happen after the Crucial "upgrade".

i use TrimEnabler. tried with and without TrimEnabler but couldn't understand if it made any difference.

upgrade with corsair 9-9-9-24 1.5v 16GB RAM.

memtest executed in single user mode with options "all" and "3" passages, OK.

problem still occurs.

all permissions verified and corrected.

any ideas? please...!
