If you are like I was and find that your ##GB USB key is only showing 2MB or 3MB and needs to be formatted, you might need to “clean” it. These directions are for a Windows computer:
Open an Administrative Command Prompt:
DISKPART> list disk
Disk ### Status Size Free Dyn Gpt
——– ————- ——- ——- — —
Disk 0 Online 408 GB 0 B
Disk 1 Online 7509 MB 6619 MB
DISKPART> select disk 1
Disk 1 is now the selected disk.
DiskPart succeeded in cleaning the disk.
DISKPART> create partition primary
DiskPart succeeded in creating the specified partition.
You will then need to Format the USB key like usual.
This is pretty much a lot of copy and paste from here the article on the Apple Support site, but I wanted to find it easier than looking on their site.
See if the bad update was installed:
Follow these steps to see if the update was installed on your Mac.
- Launch the System Information app (Applications > Utilities or hold down the Option key and select Apple menu > System Information).
- In the left column, look for the Software header and expand it if needed. Select Installations.
- In the list in the top section of the main window, click the Software Name header to alphabetize the list.
- Scroll though the list and look for “Incompatible Kernel Extension Configuration Data” in the Software Name column. Then look at the version number.
- If the version is 3.28.1, you have the bad update and will need to get the latest version.
Install the new update via Wi-Fi:
Assuming you have Wi-Fi, you can use it to get the update. Get connected over Wi-Fi and follow these steps.
- Launch Terminal (Applications > Utilities).
- Enter the following:
sudo softwareupdate —background
This will update Incompatible Kernel Extension Configuration Data to version 3.28.2, which will correct the problem.
If you are like me want just want it disable to save disk space:
- Open an elevated command prompt
- Type in “powercfg -h [off/on]”
- Hit ENTER
- IF ON A LAPTOP: Look under Control Panel-> Power Options->Change Plan Settings->Change Advanced Power Settings->Battery and make sure none of the options are set to use “Hibernate”
High CPU load caused by the rundll32.exe file seen with any windows 7, 8, 8.1, and 10 upgrade or installation. The following items need to be disabled:
- Control Panel->Administrative tools->Task Scheduler
- Browse into Task Scheduler Library->Microsoft->Windows->Customer Experience Improvement Program
- Disable (right-click) all 3 of the following items under here: Consolidator, KernelCeipTask, UsbCeip
You shouldn’t see rundll32.exe chewing up so much CPU. On a windows 10 machine (upgraded from Windows 7) I worked on tonight this change made it so when launching and App you went from 20-60 seconds of delay to almost no delay at all.
Please perform the following steps:
1. Open a command prompt as administrator.
2. Run Diskpart application by typing Diskpart in the command prompt.
3. In the “Diskpart” prompt, enter rescan command and press Enter key to re-scan all partitions, volumes and drives available.
4. Then type in list disk and press Enter key to show all hard disk drive available.
5. Select the disk that contains the partition you want to remove. Normally, with just 1 hard disk, it will be disk 0. So the command will be:
Select disk 0
Finish by Enter key.
6. Type list partition and press Enter key to show all available and created partition in the disk selected.
7. Select the partition that wanted to be deleted by using the following command, followed by Enter key:
Select partition x
Where x is the number of the recovery partition to be removed and unlocked its space. Be careful with the number of this partition, as wrong number may get data wipes off.
8. Finally, type in delete partition override and press Enter key.
