This SMC firmware update is designed for early 2006 Apple iMacs with Intel processors. It aims to optimize system performance and fix any potential bugs or issues related to the SMC (System Management Controller) firmware.
There are two parts to the process: Installing the firmware update application and then utilizing the firmware update application to install the SMC Firmware Update. Here are the steps to follow:
1. Start by downloading the SMC Firmware Update 1.0 from Apple Downloads.
2. Close all applications that are marked in the Dock with a small triangle.
3. Then double-click on the SMC Update.pkg file.
4. After reading the licensing agreement, click on Continue and then click Agree if you accept the terms.
5. Click Install to install the update application.
6. Once the software is successfully installed, click Close to start the updater application. You can find the updater in /Applications/Utilities, in case you skipped this part.
7. After reading the onscreen firmware update installation instructions, restart your computer to proceed. While your computer starts, the SMC will be updated, and your computer's fans will run at full speed during the update, but will return to normal once the update completes. Do not interrupt the update process.
Once the firmware update is complete, the computer will restart again, and you should see a message stating that the update was successful. Click OK to continue. If you see the dialog that you saw in step 7 instead of a message that the update was successful, try installing the update again (use the updater in /Applications/Utilities/). Do not interrupt the update.
One important requirement to note is that this firmware update only works on iMac (Early 2006) computers. By following these steps, you can install the SMC Firmware Update 1.0 effectively and improve the System Management Control (SMC) firmware on your computer.
