![]() When you’ve created your partition(s) – or if you’ve simply decided to wipe macOS and start from fresh – you next need to create a bootable USB stick with the latest version of Linux Mint on it. Mint has a clean, stylish design Linux Mint I did this on my iMac, and it seems to have worked fine. This basically acts as extra memory, in case the computer’s RAM ever fills up. Some people recommend creating a third partition, named SWAP, which is at least the same size as the amount of RAM inside your Mac. There’s a good guide to creating a partition for Linux here, once you’ve cleared sufficient space. You’ll need some free storage space (I’d say at least 40GB) to do this, so check your free storage first. Those looking to install Linux alongside macOS will need to use the Mac’s Disk Utility to create a partition on their hard disk for Linux to live in. If you want to keep all your files etc, make sure you have a backup, in case something goes wrong. Warning: this process is a little technical and carries a degree of risk. If you decide to install Linux alongside macOS, you’ll need to create space for it on your hard disk (or SSD) first. Wiping everything and starting from scratch is certainly easier, but you will lose all your apps, files and other data stored on the Mac. When it comes to installing Linux Mint on your Mac, you’ve got two choices: wipe out macOS and replace it with Linux Mint, or install Linux Mint alongside macOS. You’ll also need a USB stick with at least 4GB of storage. Definitely make sure you’ve got a full backup of any data you want to keep on the Mac before you embark on the process. The process is quite involved and best left to someone who knows their way around a computer. Installing Linux on a Mac isn’t without risks. There is a slight learning curve, and some things will work differently, but it shouldn’t be an entirely alien environment. It might not have the visual finesse of macOS, but you shouldn’t have too much trouble finding your way around. It’s a good-looking operating system, too. There are plenty more pre-installed apps and there’s a software store to add more. Please visit the official guide for OpenCore below to know how to configure EFI for your build.In terms of installed software, it has the Firefox web browser, Thunderbird for collecting email, and the superb LibreOffice for bashing out documents, spreadsheets and presentations. BUT, you will still need to continue the journey to the making or configuring the EFI. At this point, the macOS Catalina USB Installer is ready. Now copy the two files (BaseSystem.chunklist and BaseSystem.dmg) to the from the folder OpenCore-0.6.4-RELEASE/Utilities/macrecovery.ĭone. This OPENCORE is the USB partition we’ve mounted from the step above.Ĭreate a new folder called. Now my partition is mounted at / media/dhani/OPENCORE.įirst, we need to make a new directory inside the OPENCORE partition. Open Disks and then select the USB drive as shown below.Ĭlick the Mount button (little black triangle). I will use the Disks application that comes with Ubuntu 20.10. Now, we need to mount the OPENCORE partition we’ve created using the above method. The command will format the USB drive to FAT32 and rename it to OPENCORE. sudo umount /dev/sdb1Īnd then use this command sudo mkfs.vfat -F 32 -n "OPENCORE" /dev/sdb1 As you can see, my USB disk is mounted as /media/dhani/EFI. Now there is a partition /dev/sdb1 under /dev/sdb. Make sure there is no error on this process. ![]() ![]() Now type n to create a new partition table. Now type o to clear/delete all the partition tables that exist on the USB drive.Īnswer y and press Enter. Open Terminal and execute this command to check our USB drive lsblkĪs you can see, my SandDisk USB drive is recognized as sdb. Make sure there is no important data in it. Plug in the USB drive to the Ubuntu 20.10. Now we have all we need to build the macOS Catalina USB Installer. Wait until the download completes.Īfter the download process completed, you should see the following files inside the macrecovery folder macrecovery.py -b Mac-00BE6ED71E35EB86 -m 00000000000000000 downloadĪs you can see, I use python3 since I have the Python version 3.6.8 installed on my Ubuntu 20.10. cd ~/Downloads/OpenCorePkg-master/Utilities/macrecoveryĪnd then use this command to download macOS Catalina python3. First, open Terminal and then cd to the macrecovery folder inside the OpenCorePkg-master/Utilities/macrecovery folder. Make sure you are connected to the internet. Next, extract the Zip file and it will create a new directory called something like OpenCore-0.6.4-RELEASE. Now we need to get the latest OpenCore 0.6.4. Extract the zip file and use the we will use the macrecovery.py inside the Utilities folder.
