Runaway Kernel Task process
On my computer, I had multiple versions of Snagit installed. This is because every time that I did a major upgrade the computer kept the old version.
When the computer boots up it still uses the Snagit 2019 version and libraries. When I would do capture it would mix up which version to use and get stuck in an endless loop.
The quick solution was to remove all but the current version of Snagit. In my case, it's Snagit 2020. My computer performance had improved since removing the applications. (I also restarted the computer after deleting the apps)
I notice this was a problem when using Microsoft Teams and Zoom. I am not sure why using video apps would cause an issue. I think it's just the amount of CPU that is being used.
Try This Fix!
So if you are having problems related to kernel_task, you may want to check to see if you have multiple versions of Snagit. (I assume this might be true for other system base apps.)
Note: My problem was with Snagit, your situation might be a different application.
Your best bet is to restart the computer to properly test to see if removing the old applications fixed the issue.
Thunderbolt Display Cable
One of the disadvantages of Apple's Thunderbolt display is that the cable is not all stable. This is the main cable from the back of the computer that is used to connect to a MacBook or iMac.
I have seen many Apple Thunderbolt displays encounter a tear in them because of the angle that you have to put it in a MacBook. Over time,
Unlike the power cable, there is no way to take this cable out. The end of the cable is mounted to the mainboard. So if something happens to the connector cable, you can't replace it.
You can see the cable starting to have a tear. It's only a matter of time before it breaks.
Broken but Not Dead
However the display isn't technically dead. You can still use it as an external display. Simply connect another Thunderbolt 2 cable to the port on the back of the display and then connect it to your computer.
The Apple Thunderbolt Display uses the old Thunderbolt 2 connector, not the new Thunderbolt 3 connector - also known as USB-C.
You can find a Thunderbolt 2 display cable on Amazon for about $40. That's kind of expensive for a cable but it is far cheaper than getting a brand new monitor.
One of the downsides of the new iMacs is that they don't have a DVD drive. This makes it challenging when you want to access old files or create DVD movies for events.
New External Drive
I thought DVD drives were all the same, so when it came time for me to get one I went cheap and purchased a $30 drive. What's nice is the drive had both USB 2 and USB-C ports. I was excited because I could connect this to the USB-C port and not take up any other standard USB port.
Going cheap was a big mistake.
When I started burning DVDs I got a lot of failures. Only about 1 out of 4 disks were good. This happened using the USB3 port and the ISB-C port.
I also had this problem using different computers. So the issue was with the drive. The thing is that it works fine some of the time.
I got a SuperDrive for my birthday and what a difference it makes.
I have burned 20 DVDs and they were all successful. I didn't encounter and toasted disks.
I have also access old DVDs without a problem. The drive seems much quieter than other external drives I have had in the past.
The morale of the story is to not be cheap when it comes to storage devices. Stick with brands you know.
Couple of complaints
The cable is too short. Basically, the device sits underneath the iMac monitor. Sure I can get a USB extension but that may impact the quality of data going to the drive. Come On Apple, make longer cords.
There is only one cable type - USB 3. It would be nice to have different cable options.
Have you ever wanted to take a quick picture using your iMac Camera?
You could use Apple PhotoBooth, but it can get tricky switching Cameras.
I like Quick Camera. It's a simple little app that allows you to easily save pictures.
I like it because I can check out the shot before getting on a Zoom or Microsoft Meeting calls.
If you have multiple cameras connected to your computer, You can easily switch the camera using the keyboard shortcuts. (This is also a good way to validate that the camera is properly connected to the computer. )
You can take a picture, when no one is in the picture, and use it as a background in a Zoom call.
This way if someone is actually in the background no one will know. In addition, you can turn off background lighting for those late-night zoom calls.
Getting Quick Camera
Quick Camera is available in the App Store and it's currently free.
Download Church Bulletin
Churches in Massachusetts have limited attendance because of COVID-19. I decided to create a new Keyboard Maestro Macro to download the latest church bulletin - that way I know what's going on at mu local parish.
My parish uses e-churchbulletins.com, which generates a PDF file every week. When a new bulletin gets created it overites the file on the server.
So I created the following Macro:
What this does:
Every day at 4 am, it runs a Bash script, using curl and downloads the latest bulletin and saves it to my local computer using the current day. (This way it doesn't wright over any previous downloads. )
Copy of the BASH script:
curl --output `date +%Y-%m-%d`.pdf https://www.e-churchbulletins.com/bulletins/
I have this running every day because I never know when the latest bulletin will be released.
The nice thing is that I just set it and forget it. Now I have a copy of all the church bulletins whenever I need to refer back to them.
This week I have been busy cleaning up the storage on my MacBook computer. The easy way I have found to backup files is to use iCloud. I create backup folders in my iCloud Drive and move files into that directory. On my iMac, I then move the files to an external drive.
The reason that I am doing this method, instead of just connecting the external drive to the computer, is that I want to make sure that I backup files that are worth keeping. I don't want to just throw everything on an external drive without knowing what it is.
Things I Learned About iCloud
When you move files to the iCloud drive on your computer it doesn't delete them from the computer. It basically moved it to the cloud services but you don't save space.
In order to save space you need to move the files of the iCloud service. This concept is the same as DropBox and other cloud services.
Make sure to check the Optimize Mac Storage checkbox in the iCloud settings. This will force iCloud to only download files that it needs.
You can add/remove space as needed. For example, you can upgrade to the 2TB plan for a couple of months for storage backups and then downgrade the service.
This is a great service if you are trying to clean up a couple of external drives. In addition, you can backup all your photos and videos taken on a vacation to the iCloud drive and not worry about losing them.
Often you may see strange icons next to the iCloud folder name. Here's what the icons mean:
|Cloud||Uploading to Cloud|
|Cloud with Arrow||Backed up to Cloud. Not stored locally. Tap on the folder|
|Circle with Progress||Copying locally|
Multcloud.com makes it super easy to view all your files in one simple interface. No worry about switching browsers or windows. You can move from server to server with a simple click.
The nice thing about Multcloud.com is that you can move files between cloud services. This is awesome when you're running low on space on a particular server.
You can even sync data between cloud services, ensuring that your data is always available.
The Free Plan gives you 30GB Data Traffic/Month. The next step up is $9.90 a month which gives you 150GB Data Traffic/Month.
Five Ways to get the most out of MultiCloud.com
Snapshot Of Your Cloud Accounts - At a glance you can see how much space is available in your cloud accounts.-
Move Evernote Files - You can backup your Evernote files to a different cloud service. I was able to move images from Evernote to Google Photos.
Automate Database Backups - Perform full MySQL database backups to a cloud to Amazon, Google, Drop Box. You can even schedule the transfers so you don't have to think about doing it every week.
Clean up an old Cloud Account - I setup my Mega account back in 2015 and didn't do anything with it. I basically had a lot of videos and photos. I used Multcloud.com to move these to Google Photos to free up space on Mega.
Know What You Have and Where - Multcloud.com is a great way to audit your cloud services. You can easily find files and move things around. This helps get the most out of each cloud service.
LaunchBar Image Actions
This week LaunchBar did it's yearly update (Version 6/13). The update include many changes to various features of the application. You can read all about the latest changes in the LaunchBar Release Note.
One of the changes that I wanted to check out is this Action Change:
Updated and improved image conversion actions (rotate, flip, resize, compress, etc.). They are now better chainable with subsequent actions ' the resulting images can be immediately sent to another action.
These actions are best using Instant Send. To use Instant Send, simply select an image and then click on the shift key twice. Now you have the power of LaunchBar in your hands.
Image Conversion Actions
Let's say that you need to flip an image:
- Select an Image.
- Click on the Shift Key twice.
- Type in Flip
- Select Flip Image Horizontal or Flip Image Vertical
- Click Return
- Now You can perform another action, such as Resize or Recompress an Image.
To perform a compression, type in Recompress. To Resize the image, type in Resize. You can perform various actions to the same image.
The last task can be to airdrop the file to someone. Simply type in air and then
Just keep in mind when you perform these actions, the original image will be modified. If you want to do a comparison of the image, make a copy of the image.
New iPhones Coming Soon
Apple will be making some product announcements in late September. In the past, the announcements are related to new iPhone's products and accessories.
These are perfectly timed for the Christmas Season and the Back to School shopping.
This year the announcements are a bit late perhaps because of quality control issues.
Best Time To Buy Apple Products
If you are thinking of getting a new iPhone your better off waiting for a couple of weeks - maybe a month. Even if you don't get the latest and greatest, some of the older models may have deep discounts.
To find out when to buy a Macintosh computer, I highly recommend the Mac Rumor's Buyers Guide. They are the best resource on when the best time to get a new Apple device.
This year the rumor is that the new iPhones will be using the 5G standard. There's very limited support worldwide for 5G, so it will be interesting to see how sales go.
In Boston, Verizon has 5G Ultra Wideband coverage in some parts of the Fenway area, including Fenway Park, Foxborough, Boston Marathon Finish Line, and the Boston Garden. It appears that the 5g network is best for the sports venue. Outside of these areas, you're getting the usual 4G LTE.
Macintosh HFS Disk Format
When macOS Catalina was introduced, Apple quietly made a change to how it supports old file system formats.
Apple dropped support for formatting or writing HFS disks and images, which remain supported as read-only volumes. Starting with macOS 10.15, **HFS disks can no longer be read**.
This means that if you have CDs or DVDs using this format you will start seeing this error:
Could not mount 'X. (com.apple.DiskManagement.disenter error 49153.)
There is no way around reading these disk media files in macOS Catalina and beyond. You will need to rollback to the previous MacOS or use an older iMac.
Remember this doesn't happen to all media. Only media files that used HFS disk format.
Note: This also applies to USB Thumb drives. If you have some old drives that suddenly stopped working, it could be this reason.
There is a difference between HFS formats:
- HFS - Mac OS Standard, Introduced with System 2.1 in September, 1985.
- HFS+ - Mac OS Extended, Introduced as part of Mac OS 8.1 in January, 1998.
Apple stopped supporting HFS since macOS Sierra - which was released 3 years ago. Apple Still supports HFS+ format. Apple currently favors the Apple File System (APFS)
Using Disk Utility, I highlighted the file system being used my Netscape 6 CD. As you can see it was formatted for Max OS Standard. So now, if I want to get files off this CD, I have to use an old Mac. (Netscape had some cool space images on these CDs.)
