The original Mac OS used Object Pascal as its primary development platform, and the APIs were heavily based on Pascal's call semantics.Much of the Macintosh Toolbox consisted of procedure calls, passing information back and forth between the API and program using a variety of data structures based on Pascal's variant record concept.
So your Mac works like magic with your i Phone and other Apple devices.
In some cases, such as System cache cleaning, they can have unintended consequences.
For this reason, we advise against enabling any automated maintenance features of third-party utilities other than a feature for running the standard UNIX maintenance scripts automatically. System and User cache cleaning are troubleshooting steps, not part of regular maintenance.
And it works hand in hand with i Cloud to keep photos, documents, and other stuff up to date on those devices.
mac OS also comes with an entire suite of beautifully designed apps.
