UnitCache is a browser hijacker application, leveraged against Mac users. This dubious program is designed to generate monetary gains for its operators by performing intrusive actions on the users' devices. The main functionality of UnitCache allows it to take control over the more popular Web browsers and force them to open a sponsored address.

To achieve this goal, the application modifies certain browser settings such as the homepage, new tab page, and the default search engine. Afterward, it almost doesn't matter what actions the users take, as it will always result in traffic towards the sponsored address. For example, opening a new tab, initiating a search via the URL tab, or simply starting the browser will all lead to the promoted page. In addition, UnicCache also may open unwanted tabs containing shady advertisements. 

Typically, browser hijackers are meant to generate traffic towards a fake search engine, and UnitCache is certainly not an exception. It set's the affected browsers to open the  search.initialunit.com. On its own search.initialunit.com cannot deliver any results and that is why it redirects all search queries to the legitimate search.yahoo.com engine. 

Mac users should keep in mind that browser hijackers, adware, and other dubious applications are all classified as PUPs (Potentially Unwanted Programs) because of the deceptive manner in which they are spread. Underhanded tactics, such as bundling or hiding inside fake updates for popular software products, are used by these applications widely. For example, UnitCahce has been observed to be delivered via a fake Adobe Flash Player update.
