the stylus. Designs and images can be carefully
edited on the touchscreen iPad, while real-
time editing takes place on the Mac. Owners
of slightly older Macs lacking the Touch Bar
will be delighted to learn that the iPad can
become a Touch Bar itself. Effectively, with
Sidecar, you can manipulate a Mac from an iPad
and an iPad from a Mac.
To run Catalina and use Sidecar, you’ll
need a MacBook 2015 or later, a MacBook Air,
MacBook Pro, Mac Mini or iMac 2012 or later,
an iMac Pro 2017 or later, or a Mac Pro 2013
or later. The Catalina beta is currently open,
although Sidecar has not yet been added, and
MacOS Catalina is expected to be released in
full this fall.
