    How to reset the PRAM (or NVRAM) on your Mac 

    On a recent chat with Apple support, the representative suggested I reset my PRAM. From what I understand this will clear BIOS like values that may cause a Mac to malfunction. It only takes a second to do – here’s how:

    Press CMD+OPTION+P+R, then start the system. You’ll need three hands or a portable keyboard to do it.

    Hold those four keys down until you hear a second startup chime (or if you’ve previously disabled in, until you hear one chime).

    That’s it!

    Note that there are technical differences between the PRAM, NVRAM and the SMC, but I really don’t know what they are. You can reset them all to make your Mac behave if it’s doing weird things though.

    How to start Mac OS X Yosemite in Safe Mode 

    Hold down SHIFT during normal boot, until the loading bar appears. It will take longer than usual to start the system. Some services are not available.

    Safe Mode will clear several caches and verify the startup disks.

    From the command line, or on remote systems, boot into Safe Mode using this:

    sudo nvram boot-args="-x"
    

    When you want to boot into “normal” mode again, change the startup parameters to nothing:

    sudo nvram boot-args=""
    

    Very handy article from the Apple Knowledge Base:

    How to update Plesk via the Command Line 

    Plesk-LogoYou can update Plesk via the Web Interface (under Tools and Settings – Updates and Upgrades). However sometimes the interface times out, or browsers get confused – therefore it’s good to know that you can apply updates via the command line interface as well. In this article I’ll show you how (in Linux – I don’t know much about running Plesk on Windows I’m afraid).

    We need to download the standard installer script for this. It’s a powerful little tool which can also be used to add or remove components from the current Plesk installation, or to install Plesk on a barebones server.

    As of 2017 the link can be found here:

    If you click the option “Download Plesk installer for Linux”, you’ll see the actual script open in a new browser tab. Not what we want, although you could copy and paste this into a new file on your Linux system. Instead, right-click on the link and choose “Copy Link” instead.

    With that link in your clipboard, connect to your server via SSH and download the file with something like wget:

    wget http://autoinstall.plesk.com/plesk-installer?long-url-here
    

    This will result in a file called “plesk-installer” with some nasty parameters at the end, several hundred characters in total. Let’s rename it to something easier and tweak the execution permissions:

    mv plesk-installer* plesk-installer
    chmod +x plesk-installer
    

    Now we can run the script like so:

    ./plesk-installer
    
    Welcome to the Parallels Installation and Upgrade Wizard!
    ===============================================================================
    
    This wizard will guide you through the installation or upgrade process. Before
    installing or upgrading Parallels products, be sure to back up your data.
    
    To start the installation or upgrade, press N and then press Enter.
    To quit the installer, press Q and then press Enter.
    

    Follow the instructions to upgrade Plesk. You can also call the script with several options, for a full list of those call it with “–help”. To see all available versions of Plesk during the installation, use “–all-versions”, which will eventually lead you to a screen similar to this:

    Select the desired products and their versions

    N) Go to the next page; P) Go to the previous page; Q) Cancel installing
    To select a version, type the respective number;
    Select an action [N]: 
    

    If you call the script without any parameters, only micro updates and additional components are applied. Micro updates are usually applied automatically if this feature is enabled (it is by default).
