Cannot get dashboards in my MacBook

Welcome aboard to the Community, @donna58. Let's clear your cache and temporary internet files to fix unusual browser-related behaviors when using QuickBooks.

Most of the time, the stored cache on your browser can cause issues when it gets full of outdated files. To isolate the problem, let's first log in to QuickBooks in a private browsing mode by pressing these keys together, Command + Shift + N using the Safari. 

Once you're in, check if you can view your dashboard. If you do, go back to your regular browser and clear the cache. Otherwise, try using another updated, supported browser such as Firefox, Chrome, or Microsoft Edge.
