When you double–click
a doc in Finder, it opens
it in the app that macOS
associates with its file
type, such as .jpg or .rtf.
These associations may
change when you install
apps. If you Ctrl–click a
file and pick Get Info
(select it and hit Cmd+I),
you’ll see its associated
app in “Open with”. You
can change it for this file,
or click Change All... to
pick an app for all files of
this kind. Or Ctrl–click
a doc and choose Open
With..., or drag it from the
Finder onto an app.bigger drive (you can’t add one

When a tip mentions the

I GOING TO LOSE MY WORK?
So many apps now have
autosave or recovery, there’s
a good chance you won’t, even
if you haven’t recently saved
(Cmd+S). If you notice
something’s amiss before the
app stops working, use File >
Save As (hold Opt if you don’t
see this) to save a new copy,
then quit. On re–opening
the app, try the new copy,
and if it’s corrupted, try the
previous save. If the app
suddenly closes, reopen it
and see if it recovers your
document; if not, read its
help to find out where a
recovery file might exist.a pinch: see online help or user
forums for tips.

Disk Permissions
Until OS X 10.10 Yosemite,
Disk Utility had an option to verify
permissions. These were often
responsible for glitchy behavior like
settings being ignored or apps failing
to run, but are no longer an issue now.6
Restore
Select an empty drive and use
Restore to duplicate the contents of
a chosen drive. Try this for a drive that
has unrepairable problems, then erase
it; this may fix it. Again, for a startup
volume, use Recovery.Image rights from: Apple. maclife.com MAR 2020 21
