The Recovery system
contains tools to help
you look up info online
when macOS won’t start,
and to repair or reinstall
the system. Learn more
at bit.ly/mlrecovery.SAFE MODE
When you start your Mac
in Safe mode, macOS
performs extra checks
and stops certain third–
party software from
running. See how to use
it at bit.ly/mlsafemode.RESET SMC & NVRAM
These features handle
low–level functions and
store key settings for
your Mac, respectively.
Resetting them can fix
various issues described
at bit.ly/mlresetsmc and
bit.ly/mlresetnvram.HARDWARE ISSUES
Your Mac includes tools
that check for certain
hardware issues without
going to a Genius Bar.

June 2013 or later, see

Has macOS dropped OpenGL?
I’ve hit problems with apps like Blender in Mojave, which now seem to be limited by
macOS. Has Apple removed support for OpenGL and OpenCL?
Blender and other cross–platform graphics–
intensive apps usually rely on OpenGL to
render during playback, and OpenCL during
editing. Apple announced in 2018 that both
OpenGL and OpenCL are now “deprecated”.
Deprecation is odd. It doesn’t mean that
Apple is about to remove support, and parts
of macOS which were deprecated years ago
are still there. It does mean they’ll be going
away at some time, and that Apple won’t fix
remaining bugs. Apple wants developers to
move over to using Metal instead, but
unfortunately this isn’t cross–platform.
Version 2.80 of Blender should still work
well on macOS, although it’s not clear
whether that will continue to do so. If your
Mac has a supported AMD Radeon graphics
card, try AMD’s Radeon ProRender plug–in
for Blender from bit.ly/ml163bldr which could
improve performance and features. AMD
plugins support other graphics–intensive
apps which may not take best advantage of
Metal yet. The free OpenGL Extensions
Viewer (App Store) provides detailed info
about the version installed.
OpenGL and OpenCL support could
change too: depending on who buys the
new Mac Pro, Apple may yet be forced
to restore their support.How to rename Agenda:
Widget+ app without error
Normally it’s easy to change the name of
the top level folder with the extension .app
without affecting the app, and that in turn
changes the app’s name. Sometimes this
might cause problems with updates,
though, and you shouldn’t try it with an
app bundled with macOS. There’s a catch
here in that the name appears to contain
a colon, which isn’t allowed in file or folder
names in the Finder, as the colon is used
as the path delimiter. Remove that or use
a Unicode substitute and it should work.
Can I clone files between
two APFS volumes?Provided there’s sufficient free drive
space, you can copy files normally
between two APFS volumes, however
there’s no such thing as “cloning” them
here. Each APFS volume is a separate
file system, even though they may
share the same space inside a single
Container. When you copy a file from
one volume to another within the same
Container, the second file takes up its
full storage space, and is part of that
second volume.OpenGL Extensions Viewer, free from the App Store,
provides detailed information about OpenGL and
other graphics support.Tech Support & Techsplanations
