Other options
There are a lot of free options that pop up in a Google search for “OCR PDF on Mac” but be careful of what software you choose. Many of the options are from unknown developers, and there are inherently risks associated with downloading and using free software outside of the Mac App Store.
If you just need to OCR a couple of PDFs, using a free trial of PDFpen or Adobe’s Acrobat Pro will work. If you regularly work with PDFs and need a good solution, PDFpen or PDFpenPro are great options with a fixed $75 or $125 price to own the software.
In contrast, Adobe has moved to the subscription model for Adobe Acrobat Pro and runs from $15-$25/month after the trial depending on if you opt for a year’s subscription or not ($180/year total at the cheapest).
