MacOS Sierra's Main Problems and Solutions

So far, many of you may have upgraded from older Mac OS X to macOS Sierra. Although the new OS X offers many great new features, it is not immune to problems. 

So, here are the top 5 common questions that several macOS Sierra users are experiencing and may be addressing.

1. Installation macOS Sierra after your Mac will not start moving

After successfully installing macOS Sierra, some users got stuck on the first boot. Several MacBook / iMac users have a blank white screen (with the Apple logo) after updating macOS Sierra, while others are black.
If your macOS Sierra is stuck with a white/black screen, here is how it works.

• ·         Restart your Mac
• ·         Hold down the " Command , Option , P and R " keys
• ·         Reset System Management Controller
• ·         Turn Mac
• ·         Delete all connections
• ·         Take a break and plug the cable back
• ·         Start Mac
• ·         Boot it to safe mode

Note : Make  sure your Mac has at least 9 GB of free space. Also, don't forget to remove all third party keys and extensions.

2. Your Mac application crashes / he say " damaged and can not open."

Don't panic if your application crashes or finds a " damaged and unreachable " error after installing macOS Sierra . There are several tricks you can try to get around this problem.

a) Try holding down the " command + option " key while launching the application . Update the app by checking the developer's website.

b) Clear your Mac's cache:

·         Open the Finder window

·         Select " Go to Folder " from the " Start " menu

·         Enter " ~/Library/Caches " and click the " Enter " button

·         Empty folder

c) Edit your Mac's security settings

·         Go to the " Security and Privacy " system preferences

·         Take a look at " Settings "

·         Select " Yun Xu from anywhere to download the application " option

Note :  If your important data is deleted or lost due to an application crash or the wrong application is "corrupted and cannot be opened", please use the Remo Mac file recovery tool and  recover files from the trash  or easily upgrade to Sierra.

d) Restart PRAM

·         Restart your Mac

·         At startup, press and hold “Command, Options, P and R"

·         Release the key after the Mac restarts

3. Your Mac runs significantly slower after upgrading to MacOS in Sierra Leone

If you think your Mac is crawling quickly, there are very few things you can try.
a) Upgrade the RAM or reduce its usage to make the Mac run faster. By starting the “live action Monitor” and view the “memory ", check which applications consume the maximum amount of memory. Then, remove the widgets or applications that consume most of the system's memory.
b) Use the disk utility to fix your hard disk permissions.

4. You will experience slow Wi-Fi after MacOS Sierra upgrade

Slow Wi-Fi is as slow as a Mac is an annoying problem. Here are a few solutions to solve the slow Wi-Fi problem on your new macOS.
a) Turn off the Wi-Fi router and see if it needs to be updated. Also, try turning off Bluetooth

·         "Select network" option and switch to the "Advanced" tab

·         Open "Proxy" and disable the option under "Select Protocol"

·         Click "OK" and then " Apply "

c) Delete your existing Wi-Fi preferences
Be careful: Back up your Mac first because this method will delete the system configuration file.

·         Close all Wi-Fi-enabled apps

·         Go to the Wi-Fi menu and turn it off

·         Switch to the "Go" folder and select "Go to folder"

·         Navigate to /Library/Preferences/SystemConfiguration/ Location
