Disk Utility on MacBook air

When I run disk utility on my MacBook i get the following message:-

The volume /dev/disk0s2 could not be verified completely.

error: btn: invalid btn_btree.bt_key_count (expected 4024230, actual 4024282)

Snapshot is invalid.

Storage system check exit code is 0.

I tried reinstalling Mojave with no difference

MacBook Air (11-Inch, Early 2015), macOS Mojave (10.14.1)

Incompatible disk warning after re-installing Mojave Hello, I re-installed Mojave after finding Big Sur too sluggish on my iMac. After startup I always have an "Incompatible Disk. This disk uses features that are not supported on this version of MacOS" warning that does not go away. Running Disk Utility First Aid I see the following : The volume Macintosh HD was formatted by storagekitd (1677.50.1) and last modified by apfs_kext (1677.120.9). warning: apfs_sb at apfs_fs_index (4): apfs_features has unrecognized features (10) error: apfs_sb at apfs_fs_index (4): apfs_incompatible_features has unsupported flags: (0x20) Volume superblock is invalid. The volume /dev/disk1s2 could not be verified completely. Storage system check exit code is 0. What should I do? I see some recommending to completely erase the disk and then re-install - as this will once again take hours are there any simpler solutions? thanks Jan

Error Message Saying Cannot Install Mojave on Macbook Air 2015 I have sufficient disk space. I looked here and found the reset the SMC instructions. Have tried that 3 times and nothing has changed. As the installer counts down, it always hangs at the 11 minutes remaining mark and gives me the following message: An error occured validating the installer data. The download is either damaged or incomplete.

This is a Time Machine or APFS snapshot error, nothing to worry about. Not related to your system installation.
