How To Check If Your iPhone Is Brand New Or Refurbished Model

Here’s how to check if your iPhone or iPad is brand new, a replacement unit, or a refurbished model.

Step 1: Go toSettings app.
Step 2: Once in Settings, navigate to General > About
Step 3: Scroll down through all of the provided information until you find the label which gives you the device’s “Model” number. This will give you a unique number pertaining to that device which either begins with “M”, “F”, or “N”, and then followed by a series of letters and numbers.
Step 4: If your Model number starts with the letter “M”, then it is a brand new device. If the Model number begins with the letter “F” then it is a refurbished device. And if your Model number starts with a letter “N” then it is a replacement device.
  • M: Brand new device
  • F: Refurbished device
  • N: Replacement device.

Allow gatekeeper apps from anywhere in macOS

You’ll now be able to open and launch apps from anywhere under macOS Sierra, but be forewarned this turns off Gatekeeper and is not recommended for the vast majority of Mac users. Allowing apps from anywhere including unidentified developers can potentially leave a Mac vulnerable to certain malware and junkware and should be avoided by all Mac users with the exception of those with genuinely advanced abilities.

Another approach is to manually add Gatekeeper exceptions via the command line, a solution which may be more appropriate than simply allowing everything to skirt past Gatekeeper.

Returning to Default Gatekeeper Security in macOS Sierra

You can also reverse this and go back to the default strict Gatekeeper settings of only allowing apps from the Mac App Store and identified developers by issuing the following command string:

sudo spctl --master-enable

Hitting return and re-authenticating will return macOS Gatekeeper back to its strict default state of disallowing random apps from launching.

Nearly every Mac user should leave this feature enabled in the default state. If you do not have the ability to easily discern which apps are legitimate or not, you should absolutely not change this option. The “app can’t be opened because it is from an unidentified developer” message is there to offer protection to the vast majority of Mac users and should not be ignored.
