Macos sorts file randomly (at least it seems so to me) I checked other questions, checked Apple forums - the only thing I could find is Sort by / Arrange by but in my case none of their combinations helps me to get plain "by name" option, currently I can't even find any logic in how it sorts the files:


Any help is much appreciated. I'm on macOS 10.12.6.
The logic is simply that the file names you're looking at are sorted numerically. Finder takes the file names and note that they start with a number - everything up to first non-number character is then sorted numerically. 

I.e. from your example 9873613 &lt; 13480567 &lt; 39758380 &lt; 46432537 &lt; 81233033.

Note that some files have 7 digits, others have 8 digits.

In general Finder's sorting takes sequences of numeric digits and treat them as a single number to be sorted. Non-numeric parts are sorted alphabetically like you would expect. This system of collation is called "natural sorting".
