reformat your partition, and copy the data
back. For a startup volume:
- Clone the drive that has case-
sensitive formatting to another volume
using Disk Utility, SuperDuper, or Carbon
Copy Cloner. (You could use Time
Machine, but it’s an inefficient way to
restore an entire disk except in a pinch.) - Make sure you have a separate,
complete backup in case the one created
in step 1 fails. - Restart your Mac, and then hold
down Command-R before the Apple logo
appears to bring up macOS Recovery. - Click Disk Utility in the list of options
that appears. - Select the internal drive or boot
partition in the list at left. - Reformat it using a case-insensitive
option. - Right-click it and select Restore.
- From the Restore From popup
menu, select your clone. If it’s a disk
image, click the Image button to find it
on a mounted drive. - Click Restore and be prepared to
wait a long while! - When the restoration is complete,
exit Disk Utility and select Apple menu →
Startup Disk. - Select the drive to which you
restored your clone, and then click Restart.
If you’re copying an external or non-
boot volume, you can omit steps 3 and 4
above and launch Disk Utility from your
Mac in the Applications → Utilities folder.
By the way, you have of course noted
that OS X and macOS have always
retained the capitalization you use in
names as you type it in or a program
names it. That’s because the system is
case preserving: It honors capitalization,
but any variation in lower- and upper-case
is ignored in finding a file or overwriting it.
HOW TO LOAD A MASSIVE
AMOUNT OF DATA INTO
PHOTOS ON A MAC SET TO
OPTIMIZE MAC STORAGE
iCloud Photos lets you keep full-resolution
versions of your images and videos in
iCloud storage, while letting you choose to
store just optimized versions—thumbnails
and low-res video previews—on your
iPhone, iPad, or Mac. That’s great,
especially when you have more media
than storage. When you need the full
image or video, you can double-click it
within Photos to retrieve it for local use.
The conundrum can come when you
want to load a massive amount of media
data into Photos on a Mac set to Optimize
Mac Storage (in Photos → Preferences →
iCloud) all at once instead of adding to it
over time. The trick is to stagger your
import. Let’s say you have—as one
Macworld reader did—600GB of media
data and a 128GB disk drive in your Mac.
