Have you ever wondered what to do if you delete a system file from a Mac? Or maybe you’re wondering how you can get those system files back after they were deleted from the computer? While most Mac users should never modify system files in Mac OS and Mac OS X, some do anyway, and in that process of digging around in system contents, it’s possible to delete a system file or system folder either unintentionally, accidentally, or intentionally but without knowing what exactly the impact would be. Well, spoiler alert; usually the impact of deleting system files from Mac OS is that something that should work on the Mac suddenly no longer works. So what should you do in such a situation? How can you get back a system file that you have deleted from Mac OS? What should you do if you deleted an entire system folder from the Mac? This article attempts to answer that question.

Another day, another iOS beta! Apple has released iOS 11.4 beta 6 to those iPhone and iPad devices enrolled in the iOS beta testing program. This build arrives a few days after beta 5 of iOS 11.4 was released for the same devices.

If you are currently beta testing iOS, then iOS 11.4 beta 6 is available to download now from the Software Update mechanism found within the Settings app.

iOS 11.4 beta appears to mostly focus on minor bug fixes and enhancements, though testing of the Messages on iCloud feature is included as well. iMessages in iCloud aims to improve syncing of iMessages across devices by maintaining all Messages and iMessage content directly in iCloud. Previously, Messages in iCloud was being tested in prior iOS builds but was removed before they shipped tot he public.

The current final stable builds of macOS and iOS are currently versioned as iOS 11.3.1 for iPhone and iPad and macOS 10.13.4 High Sierra along with Security Update 2018-001 for Macs.

It’s fairly routine for Apple to issue several beta releases of system software before issuing the final version to the general public. Most assumptions are that the final release of iOS 11.4 (and macOS High Sierra 10.13.5 for that matter) will arrive sometime near WWDC 2018 on June 4.

If you want a podcast to automatically stop playing after a designated period of time, the little-known Sleep Timer feature in Podcasts for iPhone or iPad is for you.

Sleep Timer on Podcasts for iOS is great for people who like to listen to podcasts before sleep, while going to bed, while exercising, on a consistent commute, or performing other tasks where it’s appropriate to end a podcast in a determined amount time.

Emails often contain remotely loaded content, and most email clients, the Mac Mail app included, will default to automatically loading those remote images and remote content into an email. This is convenient and desired by many as it makes HTML and rich emails appear as intended, including things like HTML signatures.

But loading of remote content in email messages can also be undesirable for some Mac users, because remotely loaded content can also be used by an email sender to serve as a read receipt, or even as an attack vector by unscrupulous types (as we see right now with the efail GPG scare). Finally, some Mac users may want to disable remote loading of content in emails because it can reduce bandwidth usage, which can be helpful for cellular plans and low speed internet connections.

We’ll show you how to disable loading of remote content found in email messages within the Mail for Mac app.

If you’re traveling through areas of weak cellular signals and generally poor reception, you can save a significant amount of iPhone battery life simply by toggling the AirPlane Mode feature on. That may sound weird, but it really works, with the idea being that when an iPhone has an intermittent cell signal, the cellular modem continuously searches for another available cell tower, which happens to use a lot of battery power. Thus, the solution is to simply stop the iPhone from looking for a cell signal if you’re not going to have one anyway.

This trick is pretty straightforward, here’s what you need to remember:

If you’re a gaming fan and have an affinity for retro Nintendo Mario fun, then the ridiculously silly third-party hack called Jelly Mario is sure to brighten your day.

Jelly Mario basically takes the classic Nintendo Super Mario Brothers and wildly adjusts the physics so that everything is a squishy, bouncy, pliable, jelly mess, and the gameplay result is pure chaos and fairly entertaining. It’s kind of like playing QWOP meets Mario after visiting a Kool-Aid Acid Test and drinking a bit too much of the punch.

Best of all, you play the entire thing in your web browser, so you can just bounce around with it and not need to download or install anything.

Extended Attributes are metadata components that can be unique to specific files and file types on Mac OS. Those extended attributes can be anything from identifying data about the file itself, to quarantine information, origin data, label information, amongst other types of metadata.

This tutorial will walk through how to both view and remove extended attributes from a file on a Mac.
