Camn an ypone suggest an alternative app to unzip zipped files?

What is the problem with double-clicking a .zip file in the Finder and having it unzip it? Conversely, you can right-click on a file or folder, and from the Finder's secondary menu, select Compress "xyz" to zip that content. Otherwise, there is the free The UnArchiver from the Mac App Store.

Think you meant Archive Utility which is located in /Systems/Library/CoreServices/Applications.

Assuming the " Zipeg " application is still installed. On a Zip file Right Click it and choose More Info and in there, look for " Open With " and change to file association from Zipeg to Unarchive.

Change it to " Archive Utility "

Then change to " Suffit Expander " - that application is still installed ?

@ VikingOSX - My Bad and thank you for putting things right ;-)

And if Stuffit fails...
