Don, the Safari browser on a mac will automatically unzip the update package. It's important that the file *not* be unzipped. There is a thread with instructions on disabling that behavior in our forum here: http://ifly.adventurepilot.com/SUPPOR...

Please read that and see if it fixes your problem. You can also call us or e-mail support (support@adventurepilot.com) for more assistance.

Thanks!

Link works fine for me. Here's a copy-and-paste of the instructions from the linked thread (another user also suggested that Firefox worked well):

for safari users, this is how to turn off the "auto unzip function" go to... Safari Preferences General tab uncheck Open "safe" files after download... ... Or just right click on the download file and select "Download linked file" and Safari will save it as a zip file.
