Stopping automatic Mac OS Sierra download

[Leave a comment]


Mac OS Sierra automatically downloads to your system


Apple pushing their latest OS


Some users may find that they have a notification in the top right of their display, which says that Mac OS Sierra is ready to install. The notification box will have two buttons, ‘Install’ and ‘Details’ so if you don’t want to install it, then click details which will open the App Store app, which you can easily close.

There are two ways to stop this automatic download of the Sierra installer file, open your System Preferences and then click on App Store.

Option 1 – Uncheck “Automatically check for updates” This will prevent you Mac from checking for any software updates. This option if fine if you want to check for all the updates yourself.


Option 2 – Uncheck “Download newly available updates in the background” This will allow your mac to check for updates, but it won’t download them automatically, as you’ll still get a notification for the relevant update and then it’s up to yourself to download and install the update.

If you want to check your system for the Sierra installer file, it will be in your Applications folder and is called “Install macOS Sierra.app” It will usually be about 5GB in size, so if you want to save space or not install it, you can just drag this file to your trash and then empty the trash.

Hopefully Apple will change the automatic download setup, but don’t count on it happening in the near future.


You get an email every time CSF / lfd blocks an IP address from your web server which may look similar to this.

IP: xxx.xxx.xxx.xxx (Country Code/Country/hostname)
Failures: 5 ( sshd, smtpauth, etc)
Interval: 3600 seconds
Blocked: Permanent Block

Log entries:

[Date] refused connect from [IP address]


As the documentation states:


Send an email alert if an IP address is blocked by one of the [*] triggers

This setting needs to be disabled.


  1. Open the CSF config file in your web admin panel (if oyu have one) or by manually editing the file that is usually located here:
  2. Change the “LF_EMAIL_ALERT” setting to 0.
  3. Save changes.
  4. Restart the csf and lfd processes.

Block Windows 10 – Zip file


Windows 10 trying to force upgrade. System and software may not be compatible with Windows 10.


Windows 10 logo appears in bottom right corner of the screen. Messages now state that machine is on a countdown to automatically update.


Download the attached zip file, and unzip batch file to your desktop. Right click file and select ‘Run as Administrator’, the machine will now restart  This will remove the notification and block the associated windows update.

NB: If the upgrade has already started then this solution may fail. If the upgrade fails then it should revert back. If the upgrade goes through then you will need to revert system back.


If you find that your Ethernet port has stopped working, it is because of a ‘silent’ update from Apple in the last week of February, which Apple have now fixed.


A kernal extension corruption


To do the following you’ll have to connect to your WiFi network….

Hold the ‘Option’ (Left Alt) key down and then click on the Apple logo in the top left of your screen.

Click on System Information, and in the left hand navigation window scroll down to Software (click on the triangle to expand it, it you have to), and then click on Installations.

It should be in alphabetical order, but if not then click on the Software Name in the right hand window. Scroll down till you find ‘Incompatible Kernal Extension Configuration Data’. There will probably be three listings from different dates. The last one should be version 3.28.2 and have a date from the 28th February onwards. If you have version 3.28.1 then you will need to update to the latest 3.28.2

Open Terminal (which is in Applications > Utilities)

Then type in the following command below exactly as you see it, followed by your admin password. You won’t see your password as it is permanently hidden, so don’t worry.

sudo softwareupdate –background

Quit Terminal and restart your computer.


Another way is to boot to Recovery Console, by holding Cmd R when booting the computer and then reinstalling your OS. The Terminal route is quicker and assumes you have access to a WiFi network to get your Ethernet working again.

Safari crashing when typing in search bar

[Leave a comment]


Safari crashes when typing in the address bar.


Apples servers causing the problems when trying to return queries and suggestions.


On a Desktop Mac….

Open Safari > Preferences > Search > and then untick ‘Include Safari Suggestions’ in the Smart Search Field section. Close Safari, shut down the machine and restart. You can then re-enable the ‘Include Safari Suggestions’.  If for some reason they are still getting search problems, then open Safari > Preferences > Privacy > and click on ‘Remove All Website Data’. Restart the machine and then Safari.


On an iOS device…..

Go into Settings > Safari > and turn off the toggle for ‘Safari Suggestions’, then restart the device.

If you don’t have any more problems, you can try turning the ‘Safari Suggestions’ back on, both on your iOS and Desktop device.
