I have been trying to update Solar accounts for one of our Mac computers running El Capitan and have downloaded as advised, package 3.9.8.d. However, the package refuses to verify and hangs for hours and hours. Is there a known issue for El Capitan?

The latest version of Solar Accounts (3.9.8.) is designed to run on Mac OS X 10.5 to 10.11 so you should not have any problems installing it on your Mac
We suggest that you uninstall the software; restart your computer then download our software again from this link:

If the installation still hangs please send us a screen shot showing the problem

I am having the same issues for a while now which is causing me a problems, I am going to have to choose accounting programme.
