Copying and pasting of the text Glen9999 posts is actually a full work-around in the sense that it provides the same end result as downloading the binary .puz format. After the text is cut/pasted into a .txt file and that file is opened, AcrossLite can then print the puzzle and save it in the binary format.
I've posted a few of the text files and can attest to the labor of love that Glen9999 performs in making the input ready for text. I try to backfill for him occasionally when the LAT feed is down and he's out too.
BJMcBean, give this process another try as it does indeed work on a Mac. Make sure to copy all the text (and nothing else, including blank lines) and paste it into a .txt (not .puz) file. Right/Context click on the file and select "open with", and then select "Across Lite" as the program. The puzzle should open just fine, at which point you'll be able to print it and/or save it as a binary .puz format in the event you want to save it for later on your Mac or open it with one of the mobile versions of AcrossLite.
