Automator Help - Quick action to split first page of pdf

Your operating system is too old for AppleScript/Objective-C scripts and AppleScript older than v2.4. I have no installation of Mavericks (OS X 10.9.5) installed to code and test a Python solution either. Also, Apple does not offer a separate download of OS X Mavericks, so no means to install as a VM guest.

Best bet is to collect those PDFs and take them to a Mac running macOS Yosemite or later, and then use the Automator solution from my older referenced post.

Find another Mac with something newer than Mavericks on it.

Apple licensing would be infringed by posting any Apple licensed product in the cloud, and the Apple hosts of these public support communities would immediately remove any such link. For the same reason and result, privacy information is also removed from these communities.

I was tempted to write and test Python code on OS X Yosemite (10.10.6) that splits the first page from PDFs, but Python is real fussy about its indented code structure and you would need a programmer's editor that recognizes and respects Python indents to copy and paste correctly from code posted here.

The other issue about that linked code that I posted in 2021 is that it is custom code per that OP's specific requirements. It splits out a first page of the PDF as a separate PDF, and then removes that first page from the original PDF.

As an addendum, I found an old OS X Mavericks 10.9.5 bootable USB stick that I had made, but during the installation into Parallels Desktop, the Mavericks installer failed to validate and gave up.
