Red bar on container disc

In safe mode, I went through repair starting with last volume. Disc still showing red bar. Is it ok or is something wrong? The latest app I loaded was VPN but I turned it off. Could it be causing the red bar? If not, what's causing it? I already scanned for viruses.

MacBook Pro 15″, macOS 10.15

SafeBoot mode repair?


Can you show a screen shot of this red bar...(?) for clarification


Scanned for viruses how?



Boot into Internet Recovery (Option Command R) and from the dropdown menu: Utilities>  Disk Utility> run the First Aid on your Macintosh HD (and the "Macintosh HD-Data" volume as well if Catalina/Big Sur) If errors are found and repaired, run again until no errors reported.


Disk Utility>View>Show All Devices The best sequence is —

• Volume level

• Container level

• Parent drive

According to Tim Standing video "Dive into APFS . . . " at -24:18, the red bar means metadata was wrong or something happened to crash that volume or disk. This might explain the problems I've been having with the computer not working correctly.

I watched much of the video but I have neither the time or the interest to learn APFS and moving volumes around to free up space, plus I see a long thread of people attempting to do so without success. This is really annoying. It's really annoying that in order to maximize space and understand why my Mac isn't working right, I have to learn APFS.

And if I hadn't inadvertently discovered this, I wouldn't understand why it seems that far more of my storage has disappeared than it ought to.

And I've taken it to repair twice, spending money needlessly because apparently they aren't up on it either.

Any advice you could give about volumes, freeing up space, etc. would be appreciated.


?


You are well off the beaten track here. There is no learning apfs necessary and no moving Volumes around to free up space.


All Volumes share space with the Container at no penalty.

Add, delete, or erase APFS volumes in Disk Utility on Mac ...

Try something like OmniDiskSweeper for a GUI to get a good look at itemized file size and location:

The standard layout can be seen from the Terminal.app command, copy & paste:

diskutil list internal

2: Apple_APFS Container disk1 1.0 TB disk0s2


/dev/disk1 (synthesized):

#: TYPE NAME SIZE IDENTIFIER

0: APFS Container Scheme - +1.0 TB disk1

That color code is simply showing your 109.38 GB of storage —for visual clarification, to separate all Volumes hidden and not hidden, The color red has no significance.


If you switch focus to Macintosh HD -Data the colors simply changes to a different color palette .


This is normal.
