Are you not able to use Preview to sign an acrobat document?'adobe reader' used to be precisely what's required, until it was discontinued to force you onto the bloatware that is now called 'acrobat reader'. I still have the former on my comatose high sierra mac, which I have to wheel out each time I need to sign something.
Same here. I've nuked all Adobe products out of existence on all of my systems at home (including Lightroom Classic which I had used since LR 3).Gosh. I'd forgotten Acrobat ever existed. I've used Preview (and CleverPDF and PDF Converter sometimes) for everything. Most applications I have either export or print to PDF anyway. I've noted what bogdanw says above for when I've an hour or so tp play with stuff.
