I hope this is not a repeat question—searching mostly turned up various versions of people having the opposite problem.
Is there a way to manually open a file as read-only?
The use case would be a file that I generally want write access to, but on a particular occasion want to be very confident I won't accidentally modify. For example, a shared document that I sometimes need to edit but currently only want to view. As a compulsive/instinctive saver, this would be a useful way to protect myself from myself.
I'm running Big Sur 11.2.1 on an early-2014 Macbook Air.
- Get info, change my permissions to read-only, open; once finished, close, change my permissions back: This is a hassle.
- Open, immediately Save As: Ideally I want to lock myself out before I even have a chance to break the file.
- Duplicate the file, open the 'scratch' version; generally, delete the scratch version once I'm done: Still sort of a hassle, but the best Plan B I can think of.
- I imagine this can be done from Terminal, and am happy to learn how, but any sort of GUI method would be best.
- I imagine there's a way to create a service for this? Not sure where to start.
