Computer is miraculous!
As Windows Pro only supports 2 CPU sockets, after added 4 cores in VMware Fusion, the OS is still shown as 2 vCPU. To avoid this is, need to change cpuid.coresPerSocket to handle more than 2 cores.
In .vmx file change following parameter, numvcpus is the total number of cores, which can be changed in GUI. cpuid.coresPerSocket should be changed to half of numvcpus.
numvcpus = "4"
cpuid.coresPerSocket = "2"Android File Transfer Agent conflicts with Garmin Music, so need to disable it in order to work.
Open the “Activity Monitor” and kill the “Android File Transfer Agent” process. Open “System Preferences” > “Accounts”. Go to the “Login Items” tab of your user. Remove the “Android File Transfer Agent”.
Note: I haven't tried the process.
My print MF634Cx got error E015-0000, Canon support said it is not repairable. But I just got 4 new cartridges, want to reuse the ink. I bought a new MF645Cx, so want to try refilling the cartridges later. There are some refill videos on Internet.
To refill the cartridge, one method is to dig a hole, the second method is to open the cartridge.
Although some people said the number of page used indication will give error, refilled cartridge is still able to be used. Alternatively can buy CRG-054 Chip to replace it.

Click on lock icron beside address bar of browser, then view certificates.
The self generated CA certificate normally can be found in server, such as xxxx.ca.crt.
Following command will print out CA certificate, remove unnecessary lines, such as DONE, if any.
Note: I haven't validated the certificate retrieved using this method.
openssl s_client -showcerts -connect [server_address]:[port] < /dev/null | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p'Copy CA certificate into /usr/local/share/ca-certificates directory, such as xxxx.ca.crt, then run update-ca-certificates command to update system CA, then restart impacted service.
cp <xxxx.ca.crt> /usr/local/share/ca-certificates

Getting permission denied error when run ifup command, when using python3 /usr/sbin/ifup -a command, getting error as another instance of this application is already running
After using strace python3 /usr/sbin/ifup -a command, found that the command tried to access folder /run/network, but it doesn't exist.
Create folder /run/network after rebooted, then run command python3 /usr/sbin/ifup -a to bring up network manually.
Note: This is only a temporary solution, because the folder /run/network will disappear. Will troubleshoot again when got time.
