Reading a 3.5 floppy on a MacBook Pro
I want to read old IBM compatible floppy disc on my MacBook Pro via a portable disc drive
MacBook Pro 14″, 14.4
If it is a 3.5" 1.44 MB PC-formatted floppy, it may work. Details about the floppy disk? File types on the disk?
However, look upon this as an experiment. The floppy drive will have to be compatible as well, and that could be a problem. I do not know whether this would work with any of the latest Mac models or macOS versions. Someone else here may have tested this.
Any additional information about the floppy drive?
Before testing anything, make sure that the floppy is locked (write-protected).
Also, the disk material in an old diskette may have deteriorated, leading to further difficulties.
Another way could be to use an appropriate older computer (Macintosh or PC with an internal/external floppy drive) as an intermediary. Do you have access to such a machine?
Mac-formatted floppies would have other problems as well. See, for example, the following article: https://www.siber-sonic.com/mac/newmillfloppy.html .
