DECEMBER 2019 MACWORLD 15FIND 32-BIT
APPS ON YOUR
MAC THROUGH
ACTIVITY
MONITOR
There’s an app called
Activity Monitor that
you can use to
identify if an app is
32-bit or 64-bit. But it
only works when an
app is launched and
running.
- Launch Activity Monitor, which is in
Applications → Utilities. - In the CPU section, you see a list of
apps running on your Mac. Right click the
top row of categories. In the pop-up list
that appears, select Kind. - At the right end of the top row, a new
column called “Kind” should appear. You can
click, hold and drag it to a new location if you
wish. Like, say, next to the application names. - The Kind row will tell you if a running
app is 32-bit or 64-bit. You’ll need to upgrade
32-bit apps before using macOS 10.15.
HOW TO UPGRADE 32-BIT
APPS TO 64-BIT
Once you’ve identified a 32-bit app, you
need to upgrade it, or it will not work in
macOS 10.15. Upgrading it usually
involves downloading an update created
by the developer.
> If you bought the app in Apple’s App
Store, check it for any updates. Click
Updates in the left column of the App
Store app. Available updates appear in the
larger window on the right.
> Check the developer’s website for
an update.
> Some apps can look for updates
within the app. Launch the app, and look for
“Check for Updates” or something similar in
the Help menu, or in the menu named after
the app (for example, the Safari menu in
Safari), or in the app’s preferences. ■4.
