TextEdit docs opened in MacOS 12.6 Monterey are garbled

All TextEdit documents created in earlier MacOS's (High Sierra and earlier) open as badly garbled documents in my newly-installed Monterey OS's version of TextEdit. None of the obvious Options in the Open menu works, nor does Reset Prefs. I can still open those docs just fine in the High Sierra and El Capitan versions of TextEdit on older computers.

Then, there is something about those documents, and not Bean or TextEdit. What is the actual file extension on that file?

I just used the current version of Bean on macOS Ventura 13.3.1 to open both .rtf and .rtfd from several years ago. Thus, the problem is not Bean or TextEdit, but corrupted documents, or documents that are some other format than what you think they are.

Place one of this documents on your Desktop, and then launch the Terminal application. Enter the following at the Terminal prompt, where filename is the actual name of the document on your Desktop:

cd ~/Desktop
file --mime-type filename
head -n1 <<<"$(< filename)"
# {\rtf1\ansi\ansicpg1252\cocoartf1671\cocoasubrtf600

You should see something similar to the last commented output if it really is a .rtf file.

No cats were harmed in this example.


I am curious: is there any reason the last command above should be using the much shorter notation below?


head -1 filename

Thank you for your expert advice. Yes, I see in Monterey the User Fonts under Option > Go > Library > Fonts which contains the plethora of fonts old and new.


I assumed incorrectly that partitions would maintain separation between OS resources. I wanted to use older applications such as Adobe CS3 Suite that are incompatible with the newer MacOS with best performance when residing on my internal SSD, which is why I added High Sierra onto a different partition.


According to your information, this conflict means I should dump High Sierra and relegate all older applications to an older computer with MacOS El Capitan (speaking of "ancient"). That is disappointing, along with the obsolescence of many of my fonts, but since I have other computers I won't be suffering too much if I leave Monterey exclusively to its own resources.


Originally, after had installed Monterey on the fresh SSD, I found out that I could make a new partition (which I don't think I could have done with a regular HD). Will I be able to erase the added partition from the SSD without affecting the other one containing Monterey and the accompanying modern applications? This would be my first step before dealing with the font issue.


Thanks again for your help.

I don’t recommend making any changes in your disk partitioning. That was more of a suggestion for the future and a caution in case you notice other unusual behaviour. You were concerned about the operating system getting confused about the location of fonts. When you have multiple operating systems visible, that is a valid concern, regarding more than just fonts.


This is a difficult issue. Even a default installation of Monterey is extremely complicated if you look at the details (which Disk Utility is totally hiding from you). I don’t know how you made that partition. It looks like you would have to erase the entire hard drive to remove the container. I recommend leaving well enough alone for now.
