Hey, welcome to the HP Forums @yehuda1,
HP Solution Center is part of the Windows software. For Mac HP offers HP Utility and HP Scan. There is no full feature software for the OJ 4500 for Mac 10.11, but the frequently asked question section at the bottom of the following document can help answer some of the questions you may have: Installing a Mac Printer Driver Using Apple Software Update.
Please mark your post as solved if this answers your inquiry, by clicking the Accept as Solution button below.
