How come my NAS can not copy files to the Mac local HD. I just use smb to mount the NAS drive to my Mac Mini and no error message find. I can browse the NAS also but just can not copy the file. However, I try to use some application to work with the NAS, like the "Aperture". It can take a large RAW file from the NAS and also can save on local HD. Anyway, can somebody give me an advice regarding that issue. Is it cause by the OSx 10.5.3 setting wrong or it is just the NAS not compatible to Mac and NAS using with Mac is not that complicated. Thanks!!
