Likewise, I can’t run AppleWorks in Mavericks, so if I want to be able to work with my spreadsheets, I have to export them from AppleWorks (still running on my 2007 Mac mini with Snow Leopard). Problem is, I’m using Mavericks on my MacBook, so Office 2004 is not an option – nor do I want to spend the money to buy a newer version. I rarely use Microsoft Office, although I do have Office 2004 on my OS X 10.4 Tiger, 10.5 Leopard, and 10.6 Snow Leopard Macs. Unfortunately, AppleWorks is incompatible with OS X 10.7 Lion and later, so I’ve had to find an alternative since installing OS X 10.9 Mavericks on my Late 2008 Aluminum MacBook. I’m using it to replace AppleWorks, which I’ve been using since ClarisWorks 1.0 shipped back in the System 7.0 era. LibreOffice is a free alternative to the not-inexpensive Microsoft Office suite.
