So you know about SSL (or rather TLS) and you prefer things secure, so you request and pay for an officially signed certificate and configure your Apache to use it. The next days you’re feeling very Kevin Mitnicky, until some nitwit on Twitter trashes you for the ugly error-message he sees when trying to visit your supposedly “secure” site that is. https://spiredeath.weebly.com/mojave-for-unsupported-macs.html. What’s up with that?
Well, chances are that your disgruntled visitor was using a browser you didn’t test on, like Chrome on Mac for example? Because there is a small issue you have to take into account when “doing https”; both Chrome and Safari (but not Firefox) on Mac use OS X’s keychain, which does not have some of the intermediate certificates needed to establish the trust relationship between your signed certificate and the certificate authority’s root certificate.
As you can’t expect Apple to add intermediate certificates to their keychain by default (which Firefox does a pretty good job though) and you can’t ask all your OS X users to add the intermediate certificate by hand either, you’ll have to solve this yourself. A good thing Apache can help you in that department with it’s SSLCertificateChainFile directive, which
sets the optional all-in-one Udacity self driving car video lectures free download torrent. file where you can assemble the certificates of Certification Authorities (CA) which form the certificate chain of the server certificate. This starts with the issuing CA certificate of the server certificate and can range up to the root CA certificate.
If there’s only one intermediate certificate missing between your’s and the CA’s, you can export it in good old Firefox (as a pem-file), place it in the same directory as the actual certificate and use SSLCertificateChainFile to tell Apache where to find it and that should solve the nasty errors those Twittering Mac-heads get.

Available only on Mac computers that have the Apple T2 Security Chip, Startup Security Utility offers three features to help secure your Mac against unauthorized access: Firmware password protection, Secure Boot, and External Boot. Quickbooks pro 2014 download mac.
To open Startup Security Utility:
- Turn on your Mac, then press and hold Command (⌘)-R immediately after you see the Apple logo. Your Mac starts up from macOS Recovery.
- When you see the macOS Utilities window, choose Utilities > Startup Security Utility from the menu bar.
- When you're asked to authenticate, click Enter macOS Password, then choose an administrator account and enter its password.
Firmware password protection
Use a firmware password to prevent anyone who doesn't have the password from starting up from a disk other than your designated startup disk. To set a firmware password, click Turn On Firmware Password, then follow the onscreen instructions. Learn more about firmware passwords.
You can also use External Boot to prevent even those who know the firmware password from starting up from external media.

Secure Boot
Use this feature to make sure that your Mac starts up only from a legitimate, trusted operating system. Learn more about Secure Boot.
External Boot
Use this feature to control whether your Mac can start up from an external hard drive, thumb drive, or other external media. The default and most secure setting is ”Disallow booting from external media.” When this setting is selected, your Mac can't be made to start up from any external media:
- Startup Disk preferences displays a message that your security settings do not allow this Mac to use an external startup disk.
- Startup Manager allows you to select an external startup disk, but doing so causes your Mac to restart to a message that your security settings do not allow this Mac to use an external startup disk. You'll then have the option to restart from your current startup disk or select another startup disk.
To allow your Mac to use an external startup disk:
Website Is Not Secure Error
- Open Startup Security Utility.
- Select ”Allow booting from external media.”
Your Mac doesn't support booting from network volumes, whether or not you allow booting from external media. - If you want to select an external startup disk before restarting your Mac, quit Startup Security Utility, then choose Apple menu > Startup Disk.
