I'm trying to post a small performance-enhancing MacOS hack but it consistently gets caught by the security rules:

Connection not available

I've tried writing the post on desktop & mobile, Chrome & FF.

I'm picking the rule is triggered when I type out a hosts file modification as that's the only half-tricky part of the post.

Here's a screenshot of the post in Notepad:

Yes, looks like it. I have changed the rule.

Just a note regarding your content (the one in the screenshot):

oscp.apple.com is the Apple certificate validation service, used to validate digital certificates for Apple software and content. I would not block that to save a second here or there. Would much rather have that security in place.

The OCSP protocol is used to check whether or not a certificate has been revoked. In this context, it is used to give Apple the opportunity to revoke the “blessing” it has given to a specific piece of software. This could happen for example for example if Apple discovers that it contains malware, or when the software developer turns out to be a scammer, or similar situations.

Blocking OCSP does not interrupt normal certificate validation. Your Mac will still be able to tell whether or not the software has at some point received the “blessing” from Apple that makes it pass validation. If you have non-signed software or software signed by someone else than Apple, this will still be picked up by the system.

Disabling OCSP access only means that software that Apple once validated won’t be subject to checks in the future to see if Apple decided to revoke that validation.

If you're using known-good software, & getting annoyed at the slow server response from the known problematic OSCP server - which only serves to check whether the original Apple blessing is still in place & hasn't been withdrawn (I'm looking at you, Epic Games), then this is an effective speed-up hack. The likelihood of a program actually turning malicious post-install is remote.
