If you want to impress your friends in conversation, you should keep track of your Mac’s fans and relay to them how fast they tend to spin during particular tasks. If that doesn’t solve your issue, consider heading to an Apple Store, or another authorized repair shop. In these cases, resetting the SMC often works-this is the low-level controller that manages thermal management and other things.

If the hardware report says everything is fine with your fan, your issue is probably a software one. But look at all the steps carefully, and only proceed if you’re completely confident you can get this done yourself. If your fan is running, you hear a quite. It’s not impossible, however: check out iFixIt‘s guides if you want to attempt the repair yourself. With either a MacBook or MacBook Pro, you should press it to the bottom of the case. I managed to replace my own broken fan on a 2011 MacBook Pro, but the internals inside more recent Macs are a great deal less friendly for home repair. My advice: head to the Apple Store or any authorized Apple repair shop. If you have a broken fan, you need to replace it. Your Mac will test your hardware, and let you know if your fan is broken. First, select them using Command + A, then click the minus (-) icon to remove them all. On the next screen, remove every network in the list.
In the left pane, select Wi-Fi, then click the Advanced button in the bottom-right corner. Turn your computer off, then hold the “D” key while turning it on. One possible solution involves the System Preferences -> Network menu. Think your fan might be broken? The first thing you should do is launch Apple Diagnostics, one of the hidden startup options on your Mac. But for the occasional test, it’s nice to have control-just turn things back to automatic when you’re done. I really do not recommend disabling the automatic fan control: leaving your fans on constantly will wear them out and waste energy, and leaving them off will overheat your Mac over time. Turn the fan up and see if you can hear anything. To find out if your fans are working at all, you can click the “Custom” speed button.

The same goes if you see a low CPU temperature-say, around 45-and the fans are running at full speed. If you see high CPU temperatures-say, over 80 or 90 degrees-and that the fans aren’t running, you might have an issue. The minimum, current, and maximum speed are shown in that order. So it is indeed a flashed 4,1.For the most part, however, we’re interested in your fan’s current speed. The machine i'm looking at has the 2009 4,1 SMC versions and the 2010 5,1 boot rom. My Thinkpad X1 Carbon is even lighter and thinner at 2.5lbs, and also faster with far more storage and speed. At the time, it was revolutionary, but not anymore. The latest version in 2021 has shaved off a tiny bit at 2.8lbs.

Then shutdown the system and hold down the power button until a tone occurs, then the system will restart and show a progress bar to update the firmware. Macbook Air is super light and thin at about 3lbs.

You can however download the 5,1 firmware form Apple and simply mount the disk image prior to running the tool and it will work fine. That is because Apple changed the location of the 5,1 efi firmware image.

Mac Pro Firmware Upgrade Utility Released!ītw, the firmware upgrade tool 4,1 to 5,1 shows error 5570. Here are some links I found meanwhile for reference: I'm not sure what happens when mixing them, but apparently the system does either not boot or the fan's go crazy, perhaps depending whether you put a 5,1 cpu board into a 4,1 system or vise versa. So to answer my question, it is not possible to use a 5,1 CPU board in a 4,1 system or vise versa. It is important that the SMC version of the CPU and system are the same. SMC mainly deals with temperatures and fan speeds. Prepare the Mac you want to revive in DFU Mode: On a desktop Mac: disconnect Macs power cord > hold the power button and reconnect the power cord to bring the Mac to power > keep holding down the power key for 10 seconds until a DFU icon shows up on the working Mac. After upgrading a Mac Pro 4,1 to 5,1, the SMC firmware was still 1.39f5. Open Apple Configurator 2 software on the working Mac. The system and CPU board SMC version remains at 1.39f5 for the MacPro 2009. At this speed the Mac Pro is virtually silent. The firmware upgarde tool does not update the SMC firmware, but installs a different boot rom version. The vast majority of the time the Mac Pro’s single fan spins at a paltry 769 RPM. There was a misunderstanding regarding the firmware upgrade tool to upgarde a Mac Pro 4,1 to 5,1.
