Need to modify wifi, but boot locked

What is the problem?

I changed my wifi password, so I need to change it in the boot file. I can load the file into BBEdit, but when I try to change the password, BBEdit says the boot micro SD is locked.

What did you already try to solve it?

Checked the boot mSD, it shows as READ ONLY

Have you tried running in safe mode?

How would that help?

Did running in safe mode solve the problem?


Additional information about your setup

Raspberry Pi 2, OctoPi 10.15 (I think), SeeMeCNC Rostock Max V2, browser Chrome, Mac OS 11.5.

Did you use a micro SD to SD card adapter?

Yes. Same adapter I used for the original setup.

did you maybe switch it into read only by accident?

It is in the position closest to the top, just like your picture

I don't know if it's a MacOS issue (never used it) or a broken SD card.
If a SD card reached EOL it switches into read only mode for data recovery.

I would try to connect the pi to a screen, connect a keyboard and edit the file in the command line.

sudo nano /boot/octopi-wpa-supplicant.txt

I have used the Mac OS for lots of actions w/ SD cards and haven't had this issue. I'll try your suggestion and report back. Thanks!
