I'm trying to transfer the drivers for my nic to the mac performa 6400/200. The whole folder has various drivers for the encore nic and one for macos. Now it says in the read me inside the macos file that you just click the install icon and it will self install into the mac. It does not show a icon but still is compressed in a stuffit format *I assume !* I know nothing about a mac much less a stuffit format. I see my mac does have a stuffit program folder but when I open the folder that I uncompressed from a zip, it says the program is too large to be opened with blah blah blah. How do you take a zip file that was downloaded and uncompressed with winrar and make it useable in the mac. I only need the macos folder that contains the driver and text, so I assume the install is within that folder and was compressed with stuffit.
