i uninstalled paragon , ntfs drivers did not seem compatible el capitan (haven't installed on yosemite , still crashed).

ran rember overnight , passed 44 loops without failures - can tell (rember- etrecheck-logs attached).

2 hours ago ran full apple hardware tests 0 problems reported. not sure whether or bad news...

uninstalled memory sticks added seller (2x4gb) imac running stock 4gb ram only. rember check again , see whether there panic again.

if aht , rember not report memory defects, still possible ram causes kernel panics? not sure now. :(

appreciated. thank in advance.

best regards,

martin
 

attached files:

the kp report doesn't show definitive except crashed while running itunes. doubt kps being caused bad memory modules although possible. suggestion run imac in safe mode awhile see if still crashes. safe mode verify on hard drive while eliminates third party drivers , startup apps. kills sound - don't worry that. restart imac while holding down shift key hear chime (bong!). may take awhile boot up. let run way while see if crashes. if doesn't crash in safe mode, can assume problem may caused software. however, if crash in safe mode, may faced hardware defect or error.

particular model imac (27" 2011 model) has had problems graphics adapter may keep in mind.

Sean Penn, "Chapo Guzman", and Rolling Stone

if you've spare twenty minutes or (and inclination) take @ sean penn's rambling account of meeting (then) fugitive mexican drug lord "chapo" guzman. its interesting on number of levels. not quality of sean penn's journalistic work. first observation had there remarkably little actual interviewing going on. penn's limited spanish ("hola" , "adios") played part. guzman made number of statements, claiming turned narcotics because there no other means of earning living. beyond that, nothing groundbreaking. sean penn himself of polarizing figure. guy rose fame jeff spicoli fancies himself of outlaw journalist, without writing chops of hunter s. thompson. prose of intelligent man; stylist ambitions out of reach of abilities. uses word "brume" describe aftereffects of bout of flatulence. pretentious word (i presume) not technically accurate. mentions twice expensive wristwatches sported guzman's so...
