Mac Buggy after Mac OS Sierra Update? 4 Fixes Here!

Mac Buggy after Mac OS Sierra Update? 4 Fixes Here!

The much awaited Mac OS Sierra update was officially made available on the 20th of September, 2016. The brand new Mac OS boast of an advanced and more helpful Siri, optimized storage management options, full compatibility with the Apple watch and highly improved Messaging features.

But then, what good is all that if your Mac started to act buggy right after the update to Mac OS Sierra. If you are one among those small groups of unfortunate users who are having troubles with Mac OS Sierra, here are fixes that will help restore your Mac back to normal!

First, please backup your Mac!

It is highly recommended that you first back up your Mac before you carry out any of the fixes below. Please note that the fixes below have been tested and tried by many who vouch for its safety. Nonetheless, it doesn’t hurt to take the extra precaution that will allow you to simply roll back to a restore point on your Mac, created through Time Machine. Here’s a comprehensive guide on how to carry out Time Machine backups on Mac OS Sierra.

Fixing Wi-Fi issues in Mac OS Sierra

1. Deleting and force re-writing system files to fix Wi-Fi problems

A Mac without Wi-Fi is no fun. In fact, it could even almost be useless. If your Wi-Fi was working fine until before the update to Mac OS Sierra, apply the following fixes to revive your wireless connection.

  1. First, please quit all apps that are using or trying to use the internet connection (e.g. Chrome, Safari, iTunes, etc.)
  2. Turn off the problematic Wi-Fi connection
  3. Go to Finder
  4. Enter “/Library/Preferences/SystemConfiguration/”
  5. Locate the following 5 files
    1. com.apple.airport.preferences.plist
    2. com.apple.network.eapolclient.configuration.plist
    3. com.apple.wifi.message-tracer.plist
    4. NetworkInterfaces.plist
    5. preferences.plist
  6. Copy these files onto a flash drive (Precautionary step)
  7. Delete the files on your Mac OS Sierra partition, once you have a copy of them
  8. Restart your Mac
  9. Also, restart your Wi-Fi router when you restart your Mac
  10. See if your Mac OS Sierra Wi-Fi connection is back to normal!

Don’t worry about deleting the files mentioned above. Mac OS Sierra is designed to rewrite these files after a successful restart. There is a very high chance that your Wi-Fi problems will go away after you apply this simple fix.

If it still persists, try the slightly more complicated fix detailed below.

2. Fixing Mac OS Sierra problems by entering custom DNS

  1. First, please quit all apps that are using or trying to use the internet connection (e.g. Chrome, Safari, iTunes etc)
  2. Open System Preferences
  3. Go to your Wi-Fi connection and select the “Edit Locations” option
  4. Create a new Wi-Fi connection, giving it any name you choose
  5. Join this new Wi-Fi connection that you have created, by entering your Wi-Fi password if prompted
  6. After you have connected, go to advanced settings of this Wi-Fi connection
    1. Edit TCP/IP > Renew DHCP lease > Apply > DNS >
      1. Enter 8.8.8.8 and 8.8.4.4 (DNS of Google)
  7. Click OK
  8. Go to Hardware > Configure > Custom > Edit MTU number to 1453
  9. Click OK and Save

Once all the above edits are saved, your Wi-Fi connection should hopefully be working well. If not, restart your Mac and your Wi-Fi router just to be safe and see if your Wi-Fi works normally.

The above two fixes should give you about a 95% chance of restoring your Mac OS Sierra related Wi-Fi problems, especially if your Wi-Fi started acting up just after the update to Mac OS Sierra.

Performance issues after upgrade to Mac OS Sierra

After Wi-Fi issues, the second most common gripe for users who just updated to Mac OS Sierra is their Mac has become sluggish. Multi-tasking takes too long or the Mac just wakes up from sleep too slowly, etc.

There are fixes for speed issues as well. Some of the easy ones are detailed out below. For a comprehensive list of fixes, please visit this Mac OS Sierra performance troubleshooting guide.

1. Carry out an SMC Reset

An SMC reset is a soft hardware reset that will fix potential issues with thermal monitoring, the response of the power button, spin cycles of your hard drives, etc. Resetting this to factory defaults can potentially spring Mac OS Sierra back to life.

Don’t worry about deleting important user data when carrying out these resets. They are safe resets that might in the worst case scenario only require that you change your system time and so on.

To carry out an SMC reset,

  1. Shut down your Mac
  2. Unplug your Mac from the wall charger or outlet
  3. Press and hold the power button, for 15 seconds (use a timer!)
  4. Release the power button
  5. Reconnect Mac to the wall charger
  6. Wait for about 10 seconds
  7. Turn on your Mac like normal

Though very simple, this can be a miracle fix sometimes!

2. Carry out a PRAM reset

Quite similar to an SMC reset, you can also carry out a PRAM reset. Again, resetting PRAM will not result in any loss of personal user data or important system data.

  1. Power off your Mac
  2. Power on your Mac
  3. As soon as your Mac starts up, press the combination of the following keys; Option + Command + R + P (all together)
  4. Press and hold until your Mac restarts
  5. Once your Mac restarts the second time, release all keys and allow for a normal restart

Besides these fixes, it is also very important that you make sure your Mac is first compatible with Mac OS Sierra. As Mac OS Sierra is the latest OS out from Apple, it is more demanding on your Mac’s processor and memory than its predecessors like El Capitan, Yosemite or Mavericks.

Unless you bought your Mac in late 2009 or after, it probably isn’t good enough to run Mac OS Sierra. If this is the case, you have only the option of rolling back to your older version of Mac OS X, like OS X Mavericks, OS Yosemite or OS X El Capitan. Here’s a good resource on how to rollback from Mac OS Sierra to one of the older OS X versions.

10 Best VPNs to Browse the Internet More Securely

10 Best VPNs to Browse the Internet More Securely

When it comes to digital security, public Wi-Fi networks aren’t safe enough, making it much easier for hackers to access your personal data. Whether you are studying in a library or scrolling through Facebook in a coffeehouse, it is vital to have a VPN installed on your device.

VPNs work wonders when it comes to securing your internet connection. By creating an encrypted tunnel between a remote server run by the VPN service, they protect your personal data from prying eyes. There is a variety of VPNs available on the web, and we have collated a list of the best VPNs that stand out from the rest.

How to Choose a VPN

  • Free trial period – Free trials allow you to try the product risk-free. The same idea technically applies to those with 30-day full refunds as well.
  • Speed – You want your VPN to be just as fast as the internet speed at home. Good quality VPNs are ones where you see little difference between those speeds.
  • Device connection – Of course, the more devices that can connect to VPNs, the better. It increases the customers’ coverage and the product’s value. You also want to consider compatibility since fewer VPNs may work for Mac or Windows only.
  • Number of servers – The number of servers determines how much capacity a VPN can handle while you are connected. The more servers there are, the more users it can handle without running into potential disconnections or slow speeds.
  • Kill switch feature – Having this feature means that your IP address isn’t exposed if the VPN disconnects for some reason. A lack of this feature is a big deal since the whole reason why you’re paying for a VPN is to hide your IP address, among other things.

Why You Should Trust Us

Our hand-picked VPNs are incredibly efficient and offer such distinctive features that grant you safe browsing. They outperform many VPNs in terms of both speed and security. Their primary aim is to provide you the utmost security, thus enabling you to surf the web safely and prevent any potential threat from causing harm.

Among the best VPNs’ many unique features include split tunneling, strict logging policies, high encryption level, and availability of international servers. We have gathered them in this article to enlighten our readers and offer the best pieces of advice before you get one. Therefore, take our word for it, and if you go for a VPN mentioned below, you’d be fully appeased.

1. NordVPN

The most popular VPN on the market these days is NordVPN, and it’s easy to see why. It has widespread coverage, offering a selection of over 5,000 servers spanning across 59 countries.[1] Due to the high number of servers, its speed is similar to your Wi-Fi at home.

Lifehack’s CEO, Leon, has been using NordVPN for many years and wants to recommend it for its remarkable server count in different locations with no-logs policy. The VPN perfectly works with Netflix and Fire TV stick, too.

NordVPN is also compatible with Mac, Windows, and Linux. You can download the app onto Chrome, Firefox, Android, and Mac OS. Thanks to its massive coverage, it’s easy to connect multiple devices onto these servers.

In terms of pricing, while NordVPN doesn’t have a free trial period, they argue that their plans are considerably cheaper than those of their competitors. For example, a one-year plan for ExpressVPN costs $8.32 per month, but NordVPN only charges $6.99 monthly.

NordVPN has a new protocol called NordLynx that is based on WireGuard with speed benefits, though it’s still under development.[2] If you’re looking for general quality and affordability, this is one of the best VPNs around.

2. ExpressVPN

ExpressVPN is the second-best option out there for keeping your privacy while browsing the internet. Like many other VPNs here, they will encrypt your IP address, offer vast coverage, and can have multiple devices connected to their servers.

Compared to NordVPN, while the pricing point is higher, ExpressVPN’s biggest selling point is the number of countries that their connection covers. Depending on where you are in the world, this may be the only option you have. They have fewer servers — 160, to be precise — but they make up for the low server count by covering 94 countries.[3]

Cost-wise, your best bet is to go with the yearly plan where they charge $8.32 a month. They also have one- and six-month plans.

3. Surf Shark

With regards to Surf Shark, you can connect multiple devices to its servers, and it’s compatible with Windows, Linux, and Mac. It is also available on Android, iOS, Chrome, Firefox, and FireTV.

Furthermore, Surf Shark can whitelist apps and sites, letting them bypass the VPN. This, along with the lines of split-tunneling, is another feature that many VPNs offer. The difference is that Surf Shark allows you to whitelist specific apps or any website, while most VPNs will whitelist all sites or none at all.

The other consideration for this app is the price. While lower-tier plans are more expensive compared to others, Surf Shark’s 24-month plan is priced at $2.69 a month, so it’s cheaper than even NordVPN’s equivalent plan!

4. CyberGhost

Another top-reviewed VPN is CyberGhost. They’ve been around for 15 years and have fine-tuned their offers and features to stay competitive. They provide the standard package of browsing the web and logging into accounts safely and give you access to regionally blocked content.

The network also maintains security from hackers, malware, and phishing. Aside from that, you can connect multiple devices, and it’s compatible with all kinds of platforms.

What separates CyberGhost from the others is their extensive coverage. They have multiple servers, and the pricing point is still very low. It covers over 88 countries and has roughly 6200 servers for you to choose from, all while charging $2.75 for their 18-month plan.

5. IPVanish

IPVanish’s prime purpose is to give users online freedom by providing fast speeds and private connections. It’s clear that they can meet that promise as they provide many of the features that have been listed previously from their competitors.

IPVanish is a part of SugarSync now. What is that, you may ask? It’s a cloud-based service that syncs files across devices and computers for sharing, backup, and many more. What this means is that other devices can access various files and videos so long as they are connected to your specific VPN. Furthermore, it can serve as a backup plan if you get hacked or lose your device for some reason.

6. Private Internet Access

Private Internet Access (PIA) is a remarkably generous company in many ways. Aside from the obvious features, they offer great incentives and discounts for people to try out their products. They claim to be the most trustworthy and reliable VPN around, and we believe that.

One notable thing is that PIA offers a free two-month trial. Compared to other VPNs to this point, none have provided free trials (though all come with a 30-day money-back guarantee). On top of that, small businesses can avail of their VPN at a discounted rate. There is also the fact that their pricing plans go as low as $2.69 a month for two years, and they let you pay with gift cards.

In terms of specs, PIA has over 2695 servers that cover 47 countries right now.

These particular aspects make PIA unique and one of the best VPNs to consider.

7. Hotspot Shield

Hotspot Shield is all about offering protection while you’re browsing the internet or using streaming services like Netflix. The encryption is military-grade, and its speed is ultra-fast. In truth, it is even marketed as one of the fastest VPNs.

Hotspot Shield offers a plan that only costs  $7.99 a month; however, it’s one of the few in this list to provide its services for free. Like other Freemium apps, the free version comes with limited features. That said, it gives you a much better feel for the VPN.

Also, take note that the encryption feature is still there, though the limitations in the free plan include connecting to one location in the US and having limited streaming options and speed.

Buy this VPN.

8. TunnelBear

As unusual as a name choice for an online security protection service can be, TunnelBear is nothing short of incredible. It makes our list of the best VPNs for various reasons.

The biggest one is that the company goes through a yearly security audit. This is notable because many VPNs don’t bother about independent audits to ensure their systems are secure and safe from any issues. This is critical as VPNs have gotten some bad reputation over the years, as TunnelBear has noted in their post about their security audit.[4] The fact that they are doing this annually ensures that nothing is being compromised.

Furthermore, TunnelBear offers limited services for free, but even their paid plans are pretty cheap. For individuals, you’re merely paying $3.33 per month. The only catch is that you can connect five devices regardless of which paid plan you pick.

Buy this VPN.

9. Norton

Norton has been on the security scene for some time, and it’s actually one of the founders of the internet security industry. It started with virus and malware protection in 1991 and has since branched off to other sectors as the industry has shifted.

As you might expect from a company that’s been around for a long time, Norton provides excellent services, and a few of their other services have gone into the VPN package. In reality, Norton is the only one thus far to offer a password manager with their VPN services. They provide 50GB of cloud storage as well.

Advertising

Norton has one of the cheapest VPNs, considering you can get their deluxe plan at $49.99 per year. That comes up to roughly $4.17 a month. It might be slightly higher than other equivalent plans, but you get a lot of extra value that makes it worth the price.

Buy this VPN.

10. StrongVPN

The final VPN we want to cover is StrongVPN. Like many others, it’s great at blocking unnecessary web traffic and providing a fast and simple solution to navigating the internet without any hindrance.

StrongVPN has over 900 servers. It is available in more than 30 countries and compatible with all devices. Beyond that, the only notable selling point it has compared to others is that it also offers Sugarsync services and 250GB of storage, irrespective of your chosen plan.

As for the pricing, their year-long plan costs $5.83 a month, while their month-long one is $10.

Buy this VPN.

Bottom Line

Getting online protection is important these days, and companies recognize this.

With more hacks and breaches occurring every single day, the best VPNs can provide an excellent haven for many people who value their security and privacy.

We hope that by putting together this list, you’ll be able to find the best VPN that you can trust and enjoy using. As you can see, there are several great options with no real wrong one out there. Pick the VPN that’s best for you.
