Aug 12, 2018 Option 2: Uninstalling Homebrew with the Uninstall Script Manually. If you don’t like the idea of executing a script downloaded from the internet with curl (which is understandable for security conscious individuals), then you can also view, download, and review the uninstall script beforehand, and then execute it manually on the computer that you wish to remove Homebrew from. I wanted to see if I could develop on macOS Mojave. Going back to High Sierra seems like a bodge unless there is no way of getting homebrew to work.I also don't have that much storage on my computer so Installing Xcode 10 and the developer tools on Mojave and High Sierra would use up more storage. – iProgram Jun 9 '18 at 14:26.

Check compatibility

Install Pip Macos Homebrew

You can upgrade to macOS Mojave from OS X Mountain Lion or later on any of the following Mac models. Your Mac also needs at least 2GB of memory and 12.5GB of available storage space, or up to 18.5GB of storage space when upgrading from OS X Yosemite or earlier.

MacBook introduced in 2015 or later
MacBook Air introduced in 2012 or later
MacBook Pro introduced in 2012 or later
Mac mini introduced in 2012 or later
iMac introduced in 2012 or later
iMac Pro (all models)
Mac Pro introduced in 2013, plus mid-2010 or mid-2012 models with a recommended Metal-capable graphics card.

To find your Mac model, memory, storage space, and macOS version, choose About This Mac from the Apple menu . If your Mac isn't compatible with macOS Mojave, the installer will let you know.

Make a backup

Before installing any upgrade, it’s a good idea to back up your Mac. Time Machine makes it simple, and other backup methods are also available. Learn how to back up your Mac.

Get connected

It takes time to download and install macOS, so make sure that you have a reliable Internet connection. If you're using a Mac notebook computer, plug it into AC power.

Download macOS Mojave

For the strongest security and latest features, find out whether you can upgrade to macOS Catalina, the latest version of the Mac operating system.

If you still need macOS Mojave, use this App Store link: Get macOS Mojave.

Begin installation

After downloading, the installer opens automatically.

Click Continue and follow the onscreen instructions. You might find it easiest to begin installation in the evening so that it can complete overnight, if needed.

If the installer asks for permission to install a helper tool, enter the administrator name and password that you use to log in to your Mac, then click Add Helper.

Allow installation to complete

Please allow installation to complete without putting your Mac to sleep or closing its lid. Your Mac might restart, show a progress bar, or show a blank screen several times as it installs both macOS and related updates to your Mac firmware.

If you have hardware or software that isn't compatible with Mojave, you might be able to install an earlier macOS, such as High Sierra, Sierra, or El Capitan.
macOS Mojave won't install on top of a later version of macOS, but you can erase your disk first or install on another disk.
You can use macOS Recovery to reinstall macOS.

What year is it? Yeah it's December 2018. Nearly 2019. And I'm about to show you how to decrypt and copy your old 480p DVDs to your Mac. DVDs are yester-year's technology for certain. Although 90% of my collection exists on digitally available versions, I'm not inclined to re-purchase the entire collection on iTunes or Amazon. Nor am I inclined to be at the mercy of streaming services like Netflix that may have the feature one day, and due to licensing limits, lose it the next.

DVD drives have NOT been a thing for quite a few years now, so those of you who still have a DVD reader on your Mac (as I do on my 2009 Mac Pro) and haven't yet created digital copies of your DVD collections had better get cracking (intentional pun here) before you no longer have any DVD hardware available to copy them with!

Legality

Copying protected DVDs may or may not be legal in your jurisdiction so please be aware of your local laws and rights on owning and decrypting digitally protected DVDs. All of the software being used in this tutorial is legally and freely downloadable. Application of such software may depend on your local laws.

Get Homebrew

Homebrew touts itself as 'the missing package manager for macOS' and that it will 'install the stuff you need that Apple didn't.' Once installed on your Mac, you'll have access to hundreds of open source packages ready for you at your fingertips. Need to download a youtube video? Open a command prompt and type 'brew install youtube-dl'. Need to cross-compile for another platform? Type in 'brew install gcc'. Want to play Windows PC based games on macOS? Type in 'brew install wine'. It's that easy.

Installing Homebrew also couldn't be easier.

Start terminal.
At the command line type in /usr/bin/ruby -e '$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)'
Hit Return.
Hit Return again to allow the install to start.
Enter your Password.
Hit Return.

Wait for the download to start and for the installer to finish. That's it! You can get more information on Homebrew from our how-to article.

Install the decrypting software

Homebrew Macos 10.15

We'll need to make use of the legally grey software libdvdcss. To avoid legal issues, converter software like HandBrake purposefully omits the installation of this library. We can download it separately from our free and open source repository Homebrew.

Start Terminal.
At the proper enter brew install libdvdcss.
Hit enter.

Allow Homebrew to install the library and continue on to install HandBrake.

Install HandBrake

Handbrake is an open source media converter tool that is free to download and use. It can convert media between formats and of course, convert you're DVDs to digital files. Note that with the installation of the libdvdcss library, HandBrake can only convert unprotected DVDs.

Homebrew Install Macos Mojave

Navigate to the HandBrake website.
Click Download Handbrake.
Wait for the download to Complete.
Double click the downloaded HandBrake .dmg file.
Double click the HandBrake Icon.

Making copies

Once you have all of the requisite software you can now copy your collection.

Open HandBrake.
Select your DVD to copy.
Click Open.
Optionally set your quality Preset. I select HQ 480p30 Surround for my films.
Click Browse to select your save location.
Click Choose.
Clcik Start to start encoding.

The length of time to complete will depend on your hardware, the length of the media, and the quality of the conversion.

HandBrake will notify you when the job has completed.

Final comments

DVD at 480p can look old and outdated. Many streaming services have better quality visuals than physical DVDs can provide. So depending upon how much that matters to you, you might find that re-buying your favourite films and shows digitally might be worth the cost in terms of the time and effort it takes to convert them. Let us know your thoughts in the comments!
