iOS firmware files should always arrive in IPSW file format so that they can be identified and used properly. Sometimes, users may download an IPSW firmware file for iPhone or iPad and it arrives as .zip file instead of .ipsw as expected, this usually happens on Windows computers but it can happen on a Mac too.

The reason this usually happens is usually because of the web browser you used to download the IPSW firmware file which erroneously assigns it a ZIP archive extension. Fortunately this is extremely easy to fix and to change an IPSW marked as a .zip file into a IPSW .ipsw file.

Modern versions of Safari for Mac have a unique History keystroke that allows you to open prior windows and tabs from history in reverse chronological order. For example, let’s say you have closed 10 browser tabs over the course of the last hour, then hitting this keystroke 10 times would re-open each of those closed 10 Safari tabs. But this history keyboard shortcut goes beyond that too, it can also be used even after Safari has re-launched, meaning you can open the Safari browser and quickly open whatever the historically opened windows and tabs were, again depending on the number of times you hit the keystroke.

The iPhone defaults to showing message previews on the lock screen of iOS, revealing the sender name and message content text. Because of potential privacy ramifications, many users turn off message previews on the lock screen which hides the message content, but then to read the full message users have to go to the Message app, right? Not entirely. Devices equipped with Touch ID can reveal the hidden message preview directly from the lock screen simply by authenticating without unlocking the device, and without having to open the messages app at all.

This is an excellent though little-known privacy trick that lets you read hidden messages from the lock screen, it’s easy to use and implement into your work flow. Privacy conscious users should particularly enjoy this tip but it can also be helpful to anyone who just wants to keep private conversations private on the screen of an iPhone or iPad, whether it’s out in the open, on a desk, or otherwise.

Safari on the Mac has the ability to run third party plug-ins, some of which may perform additional services and bring additional functionality to the web experience. Plug-ins include things like Flash Player, Adobe Acrobat Reader, and other similar multimedia tools that are added into the browser.
