Complete EFI is available in the releases page

A simple method to install a modified BIOS is available here (no external programmer required).

Post-install

For setting up the SMBIOS info, use GenSMBIOS

• Run GenSMBIOS, pick option 1 for downloading MacSerial and Option 3 for selecting out SMBIOS

  • MacBookPro10,2

• Open Config.plist, find PlatformInfo >> Generic

  • The Serial part gets copied to SystemSerialNumber.

  • The Board Serial part gets copied to MLB.

  • The SmUUID part gets copied to SystemUUID.

Reminder that you want either an invalid serial or valid serial numbers but those not in use, you want to get a message back like: 'Invalid Serial' or 'Purchase Date not Validated'Apple Check Coverage

Recommended additional steps to improve battery life with optimized CPU power management:

• Open Terminal, copy and paste the following command:

• A customized SSDT.aml for your specific machine will now be in the directory /Users/yourusername/Library/ssdtPRGen

• Rename to SSDT-PM.aml , and copy to EFI/OC/ACPI/

• Open Config.plist, enable ACPI>>Add>>SSDT-PM.aml

• Reboot

If you are using different model and alternative kext from Other folder does not work for you. Try:

• Download and install ThinkpadAssistant
• Open the app and check the launch on login option

• Go under SystemPreferences > Keyboard > Shortcuts > Screenshots
• Click on Screenshot and recording options key map
• Press PrtSc on your keyboard (it should came out as F13)

macOS 10.15, also known as macOS Catalina, is Mac’s most recent—next-generation—operating system. Apple’s macOS Catalina comes with more to offer compared to its predecessors. A few of this operating system’s features include experience-dedicated apps for podcasts, TV, and music. The best part about this OS is that upgrading is easy and free for all Mac users.

Before getting started, you first have to check if your Mac meets Catalina’s hardware requirements so you can proceed to install it. Here is a list of Mac devices and models compatible with macOS Catalina:

• MacBook 2015 and later
• MacBook Air 2012 or later
• MacBook Pro 2012 or later
• Mac Mini 2012 or later
• iMac 2012 or later
• iMac Pro 2017 or later
• Mac Pro 2013 or later

You can follow these steps to find out the kind of Mac you have:

1. Navigate to the Apple menu.
2. Select About This Mac.
3. The Overview tab will display your Mac from the Overview tab.

Important Information About macOS Catalina

In macOS Catalina, Apple no longer supports any 32-bit apps. Therefore, any apps on your Mac that have not been updated from 32-bit to 64-bit will not function on this OS.

To identify the 32-bit apps on your Mac, follow these steps:

1. On your screen’s top left corner, click on the Apple icon.
2. Select About This Mac.
3. At the bottom of the window, click on the button labeled System Report.
4. On the window’s left side, click on Applications (under the Software section).
5. A list of applications will populate.
6. To find the 64-bitcolumn,move to the right using your cursor. Any 32-bit apps will have No listed in this column.

Before you can upgrade to macOS Catalina, there a few things you have to sort out first, such as:

• Confirmation of your Mac’s compatibility for macOS Catalina.
• Creation of a Time Machine backup.
• Ensuring your Mac has sufficient storage to download, install, and upgrade to macOS Catalina.

Creating a Time Machine Backup

Before upgrading to macOS Catalina, it is crucial to create a Time Machine backup. The reason for the backup is a safety measure for when you find your Mac to be incompatible with the Catalina OS, which means you can erase the upgrade and restore it using the backup you created.

Creating a backup whether upgrading or downgrading your Mac is not only a good idea, but also imperative. Unless you would not mind losing everything, we highly recommend creating a Time Machine backup before upgrading to macOS Catalina. Without the backup, it would take a lot of time to restore your system to its previous OS. You would have to download each program, plug-in, and driver once more.

Follow these steps to format an external hard drive for macOS:

1. Start Disk Utility, which you can find by navigating to Applications > Utilities > Disk Utility.
2. Choose the hard drive device and then click on Erase (if initiated, the process is irreversible)
3. Choose a name for your drive (e.g., My Backup) and select the format: Mac OS Extended (Journaled), then click on Erase.

Follow these steps to create a Time Machine backup drive:

1. Start Time Machine and click on Select Disk.
2. Connect a drive (reformatted or empty).
3. Select the drive you have just connected (e.g., My Backup) and click on Use Disk.
4. Click on the Backup taskbar icon and then select Backup Now.

Downloading macOS Catalina

The upgrade to the macOS Catalina process involves two steps: backup and installation. After you have created a backup, the next step is visiting the App Store to download the macOS installer. Depending on your internet speed, the download may take some time. Upon completing the download, you can install the macOS Catalina app that you can find in your Applications folder.

Storage Space Required for the Download

macOS Catalina needs storage of 12.5GB to 18GB for upgrading. Therefore, if you have insufficient space on your Mac, you can make a backup of some files then delete them from your system to avail the storage required.
