Importing high resolution ArcGIS (PC) imagery to Illustrator C4 (Mac)- "Cannot place due to an error" / "File size is too big"

i'm making large conference poster contain imagery arcgis. poster 92in 42in , imagery cover 91in 22in of page. problem need high resolution imagery, illustrator won't import files. i'm using arcgis 10.3 on windows 10 , illustrator c4 os x 10.11.1 (el capitan). have not been able import .tiff file illustrator (is possible?) , "cannot place due error" or "file big" errors when try place .png, .jpeg, .ai files exported gis. believe problem due different operating systems, however, can open , edit (resize etc.) files in preview without problem, there issue illustrator. files i'm using upwards of 150mb @ 300 dpi, i'd prefer use 600 dpi, can illustrator not handle these file sizes? don't want lose resolution using .jpeg, .pdf, etc, many types of compression cause problems vector layers arcgis.  please advise!

update aics4 ability access more 3gb of ram memory cs6 or above. never work cs4, @ least not @ resolution seem think require. in actual fact use 150ppi or lower poster , not visibly lose anything. , record, worked 17 years usgs working arcgis , ai.
