WHY CAN’T I ACCESS MY iPHONE IN THE FINDER
WHEN I CONNECT IT VIA USB?WHY WON’T MACOS
LET ME RUN THE
APP I NEED TO USE?HOW DO I OPERATE MY MAC WITHOUT
A KEYBOARD AND/OR MOUSE?IF YOUR MOUSE or keyboard isn’t
working, you might struggle to use
macOS to Ľnd out why. Activating
accessibility settings could help, but
that’s also hard without an input device.
The obvious answer is to borrow one: any
type of USB peripheral should work, and
if you can’t get both, you can manage
with one of the two. Most macOS features
can be accessed with a mouse. If you only
have a keyboard, use Cmd+Space Bar
(Spotlight) to Ľnd and open apps and
system features by name. Enter
“keyboard” for System Preferences’Keyboard pane, where in Shortcuts
> Keyboard you’ll Ľnd reminders of F–
key shortcuts. You may need to hold the
fn key as well as the function key and
modiĽers shown (F6 is Ctrl ). Make sure
Full Keyboard Access is set to All Controls
(press Ctrl+F7). You should now be able
to move to
wherever
you need and
Tab to the
required option,
then hit Space to
click or check it.IN MACOS 10.15 Catalina, desktop Ľle
exchange with iOS and iPadOS devices is
now done in Finder. Connect your iPhone
or iPad with a suitable USB cable and it
should appear in the sidebar of a Finder
window> select it to see options similar
to those previously found in iTunes. To
make this happen, you need to unlock
your iPhone (with your passcode, Touch
ID or Face ID), then select it in thesidebar, click the Trust button, and tap
the Trust option on your device. You can
check “Show this [device] when on Wi–
Fi” to see it listed in the sidebar in future
without a cable, whenever it’s on the
same network as your Mac. If the device
still isn’t visible in the sidebar after
trusting it, go to Prefs on the Finder
menu and, in the Sidebar tab, ensure
“CDs, DVDs and iOS Devices” is checked.Apple announced years ago
it’d end support for 32–bit
apps; everything is 64–bit
now. That means macOS X
10.15 can’t run 32–bit apps.
The only solution is to install
macOS 10.14 Mojave or
earlier using Parallels
Desktop or VMware Fusion
and run your 32–bit apps
within the virtual machine.Ctrl–click the accessory
in System Preferences >
Bluetooth, click the cross to
remove it, then pair it again.
If Bluetooth dies altogether,
indicated by its menu bar
icon turning into a grey
zigzag line, try a restart;
hold Shift+Opt while clicking
the icon to get a Debug
menu with a reset option.In System Prefs > Security &
Privacy > General, you can
allow only App Store apps or
include those from all
“identified developers”.
When you try to run an app
downloaded from neither of
the above, Gatekeeper will
say it “can’t be opened”. If
you’re sure it’s legit, Ctrl–
click it and choose Open.Image rights from: Apple.
